Abstract

TED is a lifestyle-based self-regulation model within NeuroAffective-CBTยฎ (NA-CBTยฎ), designed to stabilise the Bodyโ€“Brainโ€“Affect triangle by targeting three powerful yet frequently neglected regulators of emotion: sleep, movement, and diet/metabolism. Framed both as a memorable acronym and as an imaginal โ€œinner friendโ€, TED translates complex neuroscience into accessible, everyday actions that help individuals regulate mood, reduce cravings, strengthen self-esteem, and calm chronic threat responses.

Rather than replacing the medicalโ€“disease model, TED complements it by highlighting underrepresented biological and behavioural factors in psychotherapy: sleep quality, physical activity, metabolic health, and gutโ€“brain communication (Goldstein & Walker, 2014; Jacka, 2017; Kandola et al., 2019). These are conceptualised as neuroaffective regulators that shape dopamine and serotonin function, circadian rhythms, inflammatory pathways, and vagal signalling (Slavich & Irwin, 2014).

Across the previously published TED series, eight instalments explored key pillars and adjuncts in depth (Creatine, Insulin Resistance, Omega-3 Fatty Acids, Magnesium, Vitamin C, Sleep, Exercise, and Nutrition). This final article integrates those findings into a coherent, applied framework, illustrating how TED can be used in assessment, formulation, treatment planning, and ongoing monitoring within NA-CBTยฎ. While summarising converging evidence from neuroscience, nutritional psychiatry, and exercise physiology (Jacka et al., 2017; Stathopoulou et al., 2006; Craft & Perna, 2004), it also identifies priorities for future empirical research.

NeuroAffective-CBTยฎ and TED are presented as part of an emerging, neuroscience-informed โ€œfourth waveโ€ of CBT that is cognitive, behavioural, affective, and deeply embodied.

Clinician Summary

What is TED?
TED (Tiredโ€“Exerciseโ€“Diet) is a lifestyle-based self-regulation framework at the heart of NeuroAffective-CBTยฎ. It targets three key neuroaffective regulators: sleep and rest (Tired), movement and physical strengthening (Exercise), and diet/metabolism (Diet).

How is TED used?
TED operates in three interlocking ways:

  • as a checklist for physiological contributors to distress (โ€œHow tired am I? How much have I moved? What have I eaten and drunk today?โ€)
  • as an imaginal inner coach that reminds clients to โ€œTiredโ€“Exerciseโ€“Diet your way out of troubleโ€ in moments of overwhelm, shame, or hopelessness
  • as a framework for integrating sleep, movement, and nutrition into assessment, formulation, treatment planning, and relapse prevention

Why does TED matter?
By improving sleep, movement, and diet, TED reduces physiological volatility, supports more stable dopamine and serotonin function, and calms threat and prediction systems. This embodied stability makes it easier for clients to benefit from core CBT techniques such as behavioural activation, cognitive restructuring, and exposure.

How does TED relate to medical care?
TED is not a replacement for medical care, pharmacotherapy, or other specialist input. It offers a practical, neuroscience-informed way for clinicians to bring lifestyle science into therapy while working collaboratively with GPs, psychiatrists, endocrinologists, and nutrition professionals.

Introduction: From Cinema TED to Clinical TED

In the adult comedy TED, a handsome yet emotionally struggling โ€œalpha-maleโ€ forms an unlikely but deeply supportive bond with a small, wisecracking teddy bear, also called Ted. Despite his colourful vocabulary, Ted the bear becomes a reliable guide through crises, a companion the protagonist relies on when life becomes chaotic and overwhelming. He is flawed, humorous, sometimes inappropriate, but ultimately loyal and protective.

The TED model in NeuroAffective-CBTยฎ borrows from this metaphor. TED is introduced as an imaginal trusted friend or inner coach who reminds us to โ€œTiredโ€“Exerciseโ€“Diet your way out of troubleโ€ when emotions feel overwhelming. Clinically, TED operates in three interlocking ways:

  1. As a checklist โ€“ a rapid screen of sleep, movement, and diet/metabolism:
    How tired am I? How much have I moved? What have I eaten and drunk today?
  2. As an imaginal inner coach โ€“ a supportive internal friendly figure (e.g. could be, Ted the friendly teddy bear) who nudges clients toward self-care when the mind is flooded with shame, fear, or hopelessness.
  3. As a structured framework โ€“ a systematic method for integrating sleep, movement, and nutritional factors into assessment, formulation, intervention, and relapse-prevention work, ensuring that key physiological regulators of affect are addressed alongside cognitive and emotional processes.

Before describing TED in detail, it is helpful to situate it within the broader context of NeuroAffective-CBTยฎ and an emerging fourth wave of CBT.

Beyond the Medical-Disease Model: Context and Rationale

The dominant approach to psychopathology for many decades has been the medicalโ€“disease model, which frames conditions such as depression and anxiety primarily in terms of disorders of brain chemistry. In this view, dysregulation of neurotransmitters like serotonin, norepinephrine, and dopamine is considered central, and treatment often focuses on pharmacological interventions designed to increase their availability or modify their signalling.

Psychiatrically prescribed medication can be life-saving and remains an essential part of treatment for many individuals struggling with mental illness. However, this model has clear limitations. It tends to downplay psychosocial, lifestyle, and environmental contributors to mental health; it risks reinforcing a passive identity (โ€œmy brain chemicals are brokenโ€) and under-emphasising agency, context, and learning; and it often neglects the emerging evidence around gutโ€“brain communication (Mirea, 2024), inflammation (Slavich & Irwin, 2014), glucose metabolism (Inchauspe, 2023), and physical activity (Kandola et al., 2019) as major determinants of emotional regulation.

For example, approximately 95% of the bodyโ€™s serotonin is produced in the gut rather than the brain. The gut microbiome can produce GABA, a key inhibitory neurotransmitter that supports calm and relaxation. Gut health and mental health are therefore intimately linked, and interventions such as increased intake of natural pre- and probiotic foods (Greek yoghurt, kefir, garlic, green bananas, sauerkraut and others) can influence emotional states in ways that are not merely โ€œpsychologicalโ€ but physiologically grounded (Jacka, 2017; Marx et al., 2017).

At the same time, converging evidence indicates that sleep deprivation, physical inactivity, and diets high in refined carbohydrates and added sugars profoundly affect mood, cognition, and affect regulation (Baglioni et al., 2011; Walker, 2017; Lassale et al., 2019). NA-CBTยฎ and the TED model arise from the need to bring these lifestyle dimensions to the centre of psychotherapy, rather than treating them as optional โ€œwellbeing tipsโ€ or peripheral lifestyle advice. TED proposes that in order to understand emotional dysregulation, and to support sustainable change, we must consider how a person sleeps, moves, and eats as integral components of case formulation and treatment.

NeuroAffective-CBTยฎ and the Emergence of a Fourth Wave

NeuroAffective-CBTยฎ is an integrative, transdiagnostic model that remains rooted in the evidence base of CBT while extending it in several important ways. As an extension of evidence-based CBT (Hofmann et al., 2012), NeuroAffective-CBTยฎ integrates affective neuroscience and lifestyle science to address physiological and emotional regulation more comprehensively. It focuses explicitly on subclinical affective underlayers such as shame, self-loathing, and internal threat, which often cut across diagnostic categories and are central to chronic distress (Mirea, 2018a; Mirea, 2018b). It is grounded in a neuroaffective perspective that views the brainโ€™s core function as prediction and protection (McEwen, 2007). Cognition and affect are understood as inseparable: affect acts as the organismโ€™s rapid error-signalling system, whereas cognition forms the interpretative and meaning-making layer built upon it.

NA-CBTยฎ emphasises the Bodyโ€“Brainโ€“Affect triangle, recognising that physiological states shape emotional and cognitive processes and that emotions, thoughts, and behaviours in turn shape physiological states. Within the broader CBT tradition, NA-CBTยฎ and TED can be seen as part of an emerging fourth wave:

  • First wave: behavioural conditioning and observable learning.
  • Second wave: cognitive restructuring and the link between thoughts and emotions.
  • Third wave: contextual and acceptance-based models such as ACT, DBT, and mindfulness-based approaches.
  • Fourth wave (emerging): neuroscience-informed, transdiagnostic, and embodied CBT that integrates brain, body, lifestyle science, and authentic living (e.g., NeuroAffective-CBTยฎ, Hypno-CBTยฎ, Strength-based CBT, Process-based CBT).

This fourth wave synthesises and extends earlier CBT developments and incorporates insights from neuroscience, physiology, metabolism, and lifestyle science (Jacka, 2017; Kandola et al., 2019; Walker, 2017). It also examines macro-level contextual factors such as digitalisation and the increasing presence of AI, and how these shape attention, craving, emotional regulation, and interpersonal connection (Yang et al., 2016). NA-CBTยฎ positions itself at this intersection, with TED serving as the practical lifestyle-regulation arm.

Beyond the TED framework, NeuroAffective-CBTยฎ contributes several distinctive features to the emerging fourth wave of CBT. It places affective underlayers such as shame, self-loathing, and internal threat at the centre of formulation and intervention, offering a level of affective precision not typically found in traditional or third-wave models. Its Pendulum-Effect formulation provides a dynamic map of overcompensation, avoidance, and capitulation patterns, linking them directly to core affect and physiological states. NA-CBTยฎ uniquely integrates subcortical affective neuroscience, positioning precognitive affect, not cognition, as the first layer of experience. Its predictionโ€“protection model reframes symptoms as miscalibrated survival strategies rather than distortions or deficits. Through modules such as the Integrated Self, it emphasises identity consolidation and self-repair, complementing but extending beyond ACT or mindfulness-based work. Finally, NA-CBTยฎ offers a deeply embodied perspective through the Bodyโ€“Brainโ€“Affect triangle, using physiological stabilisation as a prerequisite for cognitive and emotional change. Together, these contributions position NA-CBTยฎ as a distinctive and fully articulated example of fourth-wave CBT.

Affect, Emotion and Regulation in NA-CBTยฎ

Affect regulation refers to the ability to influence more primitive feeling states and bodily arousal using skills such as cognitive reappraisal, mindfulness, imagery, grounding, expressive work, and soothing behaviours (Palmer & Alfano, 2017). Emotion regulation, in contrast, involves the capacity to notice, label, interpret, and intentionally modulate specific emotions as they arise, integrating appraisal, meaning-making, and deliberate behavioural choices in response to internal or external cues.

Within NeuroAffective-CBTยฎ, these processes are understood through the predictionโ€“protection model. The brain is constantly predicting threat or safety, using prior learning to anticipate what will happen next and how dangerous it might be. The bodyโ€™s signals would heavily shape what the brain predicts. When physiological systems become dysregulated, because of poor sleep, low movement, glucose instability, or inflammatory dietary patterns, the brain becomes more sensitive to threat cues and more prone to false alarms. Neutral events begin to feel dangerous, interpersonal signals are more easily misinterpreted, and emotional reactions tend to rise faster and hit harder.

TED was introduced more than fifteen years ago as a module within NA-CBTยฎ precisely to stabilise these underlying physiological contributors to emotional volatility. By focusing on three lifestyle domains with particularly strong evidence bases, sleep/rest, physical activity, and diet/metabolism (Baglioni et al., 2011; Craft & Perna, 2004; Jacka et al., 2017), TED offers a practical route for reducing physiological volatility and supporting emotional steadiness. It provides both a language and a structure that clinicians and clients can use together to understand why emotional regulation sometimes fails and how it can be strengthened.

Hormones, Neurotransmitters, and Emotional Regulation

Hormones exert a significant influence on how reactive, energised, and emotionally sensitive we feel. Cortisol and adrenaline shape stress readiness; thyroid hormones regulate metabolic pace and cognitive clarity; and sex hormones such as oestrogen and testosterone contribute to mood stability, drive, and motivation. Yet hormones form only one layer of a much wider regulatory system that also includes neurotransmitters, neural circuits, lifestyle patterns, and learned psychological skills.

A simple way to explain this to clients is that hormones set the stage, neurotransmitters run the reactions, and thoughts, behaviours, and lifestyle influence both. Hormones establish the background level of sensitivity and reactivity, while neurotransmitters such as serotonin, dopamine, GABA, and glutamate govern moment-to-moment emotional responses, motivation, reward, soothing, learning, and intensity (Panksepp, 1998). These biological systems are then shaped and reshaped by experiences, relationships, and daily habits operating from โ€œaboveโ€ (thinking, interpretation, meaning) and โ€œbelowโ€ (body, physiology, affect) simultaneously.

Within NeuroAffective-CBTยฎ, emotional regulation is understood as emerging from the interaction between these interconnected levels. At the neural level, the prefrontal cortex supports planning, perspective-taking, and self-control; the amygdala detects threat and salience; and the hippocampus encodes context and meaning. These structures interact through networks of neurotransmittersโ€”serotonin supporting emotional steadiness, dopamine driving motivation and reward learning, GABA providing inhibitory calming, and glutamate facilitating excitation and learning (Panksepp, 1998; Serafini, 2012).

Hormonal systems modulate these neural processes by altering baseline arousal, sensitivity to stress, and metabolic readiness. Lifestyle factors such as sleep, movement, nutrition, blood sugar regulation, shape both hormonal and neurotransmitter environments. Learned psychological skills, such as cognitive restructuring, self-talk, mindfulness, and compassion, help individuals interpret and respond to internal and external events in ways that either escalate or soften emotional arousal.

Hormones therefore influence emotional life, but they do not dictate it. When cortisol is high, for instance, the body enters a stress-ready state; yet whether a person calms themselves, reframes the situation, seeks support, or spirals into panic depends on their skills, histories, and existing neural pathways, not cortisol alone. This perspective is central to NA-CBTยฎ: it reduces a sense of biological fatalism and invites clients to see emotional regulation as a system they can influence rather than a fate imposed by hormones.

Within this model, affect originates in evolutionarily older systems. Jaak Pankseppโ€™s (1998) work on primary affective systems suggests that mammals share basic circuits such as RAGE (anger), FEAR, PANIC/GRIEF (sadness), LUST, CARE, SEEKING, and PLAY (joy). These are precognitive, rapid, and deeply embodied. Once their signals enter awareness, they move into the domain of emotion, where the prefrontal cortex and associated networks interpret, label, and contextualise them in light of memory, beliefs, and social learning. Shame and guilt, for example, are not primary affects but secondary, cognitively mediated emotions, as they require self-reflection and social evaluation.

This distinction is clinically important. It helps therapists and clients recognise that intense feelings often reflect rapid, subcortical affective activations rather than โ€œirrationalityโ€ or โ€œcharacter flawsโ€. It also underscores that emotional regulation must work in both directions: bottom up, through body, affect, and physiology, and top down, through cognition, meaning, and narrative (Palmer & Alfano, 2017).

TED targets this integrated system primarily from the bottom up. By stabilising sleep (Walker, 2017), movement (Craft & Perna, 2004), and nutrition (Jacka et al., 2017), TED reduces physiological volatility, supports more predictable affective responses, and makes higher-order emotional skills easier to access and practise in therapy.

The TED Model: Structure, Metaphor, and Mechanisms

Within NeuroAffective-CBTยฎ, TED occupies a central position. The standard six-module structure of NA-CBTยฎ comprises: Assessment and the Pendulum-Effect formulation; Psychoeducation and Motivation; TED (Tiredโ€“Exerciseโ€“Diet); the Integrated Self; Coping Skills; and Relapse Prevention. Although presented as discrete modules, the middle sections are conceptualised as intersecting and interchangeable; clinicians are encouraged to move fluidly between them according to client readiness, therapeutic timing, and clinical priorities. The only fixed elements are that therapy begins with a comprehensive assessment and concludes with relapse-prevention planning.

TED is formally introduced in Module 3, but its principles are woven throughout Modules 3 to 6, supporting emotional regulation, cognitive flexibility, and long-term resilience (see Figure 2). Clinically, TED can be summarised in a single phrase: โ€œTiredโ€“Exerciseโ€“Diet your way out of trouble.โ€ Yet behind this apparently simple slogan lies a structured framework.


Figure [1]

TED sits at the centre of the model because stabilising sleep, movement, and nutrition provides the physiological foundation required for deeper cognitive, emotional, and behavioural change across all later modules.


There are three main ways in which TED operates. It functions as a checklist: Has this person slept? How well? Have they moved today? What, when, and how have they eaten and drunk? It functions as a personal guide or inner friend: the internal TED who nudges us towards healthier choices when the mind feels overwhelmed or hopeless. And finally, it functions as a framework for assessment, formulation, and intervention, integrating physiological, emotional, and cognitive levels into a coherent plan.

The empirical foundation for TED rests on a substantial body of research showing that sleep quality, physical activity, and diet consistently predict mental health outcomes, including mood, cognitive function, and stress resilience. Studies in student, adult, and clinical samples repeatedly highlight that these โ€œbig threeโ€ health behaviours are strongly associated with emotional well-being. TEDโ€™s contribution is to translate this knowledge into a simple, clinically actionable structure that fits naturally within CBT practice.

With this backdrop, we can turn to the three pillars of TED in more detail.

The โ€œTโ€: Tired โ€“ Sleep and Rest

โ€œTโ€ stands simultaneously for being physically tired and emotionally exhausted. It signals the need to attend to basic sleep hygiene and rest, and it can also carry a motivational subtext: โ€œArenโ€™t you tired of feeling this way? Let us sleep, exercise, and diet our way out of this.โ€

Sleep deprivation is now recognised as a central risk factor for a wide range of mental health problems (Baglioni et al., 2011; Mauss et al., 2013). Across decades of research, no major psychiatric condition has been found in which sleep is consistently normal. Everyday experience aligns with this: a parent who has slept poorly commonly reports a โ€œshort fuseโ€, heightened irritability, and emotional reactivity the next day.

Neuroscientific work, including studies from the University of California, Berkeley, has helped clarify why this occurs. When well rested, medial prefrontal regions maintain robust connections with the amygdala, acting as a rational, context-sensitive control system for emotional responses (Goldstein & Walker, 2014). Under sleep deprivation, this connection weakens or โ€œdecouplesโ€, leaving the amygdala hyper-reactive and more likely to misinterpret neutral or mildly unpleasant stimuli as threatening (Ben Simon et al., 2020). As a result, individuals become more emotionally volatile with reduced regulatory capacity.

Despite this evidence, sleep is still often under-assessed in psychotherapy. NA-CBTยฎ and TED place sleep at the centre of affect regulation work. Clinically, this includes not only encouraging approximate targets such as eight hours of sleep per night, aligned as far as possible with natural circadian rhythms and dark hours, but also exploring beliefs and emotions around sleep itself. Many clients experience shame and performance anxiety about their sleep, viewing it as another area of failure. Non-punitive sleep logging, focusing on patterns and benefits rather than self-criticism, becomes an important intervention. Psychoeducation based on accessible resources, such as the work of Matthew Walker (Walker, 2017), supports behavioural changes and provides a compelling rationale for prioritising sleep.

TED also draws attention to behaviours that undermine sleep: heavy meals or late strength training close to bedtime, late-night screen use, excessive caffeine, alcohol effects on sleep architecture, and unregulated napping. Addressing these patterns often yields surprisingly rapid improvements not only in fatigue but also in mood, cognitive clarity, concentration, and stress tolerance (Palmer & Alfano, 2017).

Sleep is therefore not a peripheral wellbeing tip but a central determinant of emotional regulation. Within the TED model, stabilising sleep is treated as a primary intervention that reduces baseline physiological volatility, allowing clients to access higher-order cognitive and emotional skills more effectively during therapy.

The โ€œEโ€: Exercise โ€“ Movement and Strength

โ€œEโ€ represents exercise, or more broadly movement and physical strengthening. Regular physical activity is one of the most robust non-pharmacological interventions for mental health (Craft & Perna, 2004; Stathopoulou et al., 2006; Kandola et al., 2019). It supports immune function and hormonal regulation, increases neuroplasticity and brain-derived growth factors, enhances protein synthesis and brain repair, reduces stress hormones, and improves mood. Importantly, it also strengthens self-efficacy and body confidence, which are highly relevant in work with shame and self-loathing.

From an evolutionary perspective, human bodies and brains developed in environments that demanded varied physical activity, not sedentary, screen-based living combined with high-sugar food availability. Our speciesโ€™ curiosity, resilience, and physical robustness historically supported exploration and survival; TED reintroduces these ingredients in a modern therapeutic context, not as idealised athletic targets but as realistic, sustainable movement practices that support emotional regulation.

Within TED and NA-CBTยฎ, exercise is always tailored to the individualโ€™s age, sex, health status, cultural context, and physical ability. The emphasis falls on daily, sustainable movement, not perfection or performance. Therapy may involve alternating between strengthening and relaxation-focused modalities: for example, combining resistance training, walking, or team sports with practices such as yoga, breath-based techniques, or Progressive Muscle Relaxation (PMR).

PMR, first described by Edmund Jacobson (Jacobson, 1974), is particularly relevant in NA-CBTยฎ. Clients sequentially tense and relax muscle groups while practising diaphragmatic breathing and focused attention. Over time, they learn to distinguish โ€œtenseโ€ from โ€œrelaxedโ€ internal states, identify where stress is held in the body, and actively release muscular tension. This somatic awareness often becomes an anchor in emotional regulation work, especially for individuals who struggle to notice early signs of escalation.

Condition-specific approaches can also be used judiciously. Martial arts may support people with low confidence or assertiveness difficulties, providing a structured, embodied context for practising boundaries and power. Team sports can evolve into graded-exposure opportunities for those with social anxiety, allowing contact and cooperation in a meaningful, non-clinical context. In contrast, bodybuilding may be contraindicated for some clients with body dysmorphic disorder where it risks reinforcing preoccupation and compulsive checking. In each case, the task is to co-design a movement plan that honours the clientโ€™s values, identity, and health, while gently expanding their sense of agency.

Beyond emotional regulation, exercise directly affects metabolic and reward systems. Regular movement increases muscle mass and therefore glucose-storage capacity, making metabolic stability easier to achieve (Kandola et al., 2019). As insulin sensitivity improves, emotional fluctuations and cravings often reduce. Exercise also influences dopamine pathways associated with motivation, anticipation, and reward learning (Phillips, 2017), contributing to reductions in rumination, anhedonia, and stress reactivity.

In this way, the exercise pillar of TED becomes more than a behavioural recommendation; it is a neuroaffective intervention that shapes physiology, emotion, and cognition simultaneously.

The โ€œDโ€: Diet โ€“ Nutrition, Metabolism, and the Bodyโ€“Brain-Affect Axis

โ€œDโ€ stands for diet, encompassing both eating and drinking. The link between diet and mental health is surprisingly direct and increasingly well-documented, yet historically it has been underexamined within psychological practice. Food is not simply fuel or a matter of โ€œhealthyโ€ versus โ€œunhealthyโ€ choices. It is deeply cultural, embedded in rituals, celebrations, and identity; it is emotional, tied to comfort, attachment, and memories; it is social and sometimes spiritual, woven into community life, values, and fasting practices.

TED recognises this complexity while focusing on the core biological mechanisms through which diet influences emotional regulation, cognition, and motivation. Modern diets in many contexts are high in refined carbohydrates and added sugars. This pattern produces repeated glucose spikes that contribute to increased fat storage, low-grade systemic inflammation, accelerated tissue ageing through glycation, and insulin resistance that can progress to type 2 diabetes. Crucially, early metabolic dysregulation often presents with psychological symptoms such as irritability, anxiety, low motivation, disturbed sleep, reduced libido, fluctuations in mood, and emotional reactivity. It is not uncommon for individuals to be treated for anxiety or depression without screening for metabolic contributors.

Insulin is central to this picture, transporting glucose into liver and muscle cells and, once those are saturated, into fat cells. Regular exercise increases muscle mass and therefore increases glucose-storage capacity, illustrating the synergy between the exercise and diet pillars of TED (Craft & Perna, 2004). As insulin sensitivity improves, blood sugar levels become more stable, and emotional fluctuations and cravings often reduce (Inchauspe, 2023).

From a neurobiological standpoint, sugar dependence can be genuinely difficult to shift. Repeated sugar intake drives dopamine release and reinforces reward learning in patterns that resemble other habit-forming or addictive patterns (Stathopoulou et al., 2006; Wise et al., 2016). Over time, a paradox often emerges: people feel less energised but more dependent on sugar, even as health consequences accumulate.

Emerging research on the gutโ€“brain axis extends this understanding beyond microbiome composition alone. Work by researchers such as Maya Kaelberer has identified specialised neuropod cells in the gut that detect nutrients like glucose and amino acids and convert this detection into fast electrical signals to the brain (Kaelberer et al., 2018). This suggests that the gut can detect genuine metabolic reward and communicate it within milliseconds, helping explain why organisms consistently prefer sugar-water to certain artificial sweeteners even when both taste equally sweet. For clients, this underscores that cravings are not purely โ€œin the mindโ€; they reflect learned neurobiological patterns linking gut detection, dopamine, and prediction.

Diet quality also interacts with inflammation and depression. Mediterranean-style diets rich in vegetables, fruits, fibre, fish, and healthy fats are associated with reduced depressive symptoms and improved emotional resilience (Jacka et al., 2017; Opie et al., 2018; Lassale et al., 2019). Conversely, ultra-processed, high-sugar diets increase systemic inflammation, a robust predictor of depression, anxiety, and metabolic disorders (Slavich & Irwin, 2014). Diets rich in micronutrientsโ€”including B-vitamins, folate, omega-3 fatty acids, vitamin D, magnesium, and vitamin Cโ€”support neuroplasticity and new learning, which are central to emotional flexibility in CBT (Serafini, 2012; Andrรฉ et al., 2008).

TED therefore treats diet as a neuroaffective process rather than a purely behavioural one. In clinical work, this may involve exploring not only what people eat but why, when, and how. Beliefs such as โ€œFood is good if it tastes goodโ€, โ€œEating this makes me a good or bad personโ€, or โ€œI deserve this after a hard dayโ€ are explored gently. Through mindful eating and cognitive reframing, clients learn to soften rigid narratives, reduce guilt, stabilise eating patterns, and cultivate a more compassionate approach to self and nourishment.

Psychological Assessment and Bloodwork Analysis

Although TED is a lifestyle-first framework, it recognises that specific micronutrients can provide meaningful support for mood, energy, and emotional balance when used appropriately. Vitamin C contributes to the synthesis of key neurotransmitters involved in stress and well-being (Serafini, 2012); magnesium supports sleep, muscle relaxation, and anxiety regulation (Palmer & Alfano, 2017); omega-3 fatty acids reduce inflammation and support brain health (Marx et al., 2017); vitamin D plays a central role in immunity and mood stability, particularly in winter months (Lassale et al., 2019); and creatine enhances cellular energy, with emerging evidence for its role in stress tolerance and cognitive functioning (Juneja et al., 2024).

TED does not promote supplements as substitutes for sleep, movement, nutrition, or appropriately prescribed treatment. Rather, it emphasises careful physiological assessment at the outset of therapy, so that these foundational systems can be supported and improved. Many experiences that are often interpreted as purely psychological, fatigue, irritability, low mood, mental fog, anxiety, can in fact arise from underlying physiological issues such as dysregulated blood glucose or early insulin resistance (Jacka, 2017; Inchauspe, 2023), vitamin D deficiency (Lassale et al., 2019), iron deficiency (particularly in women), vitamin B12 insufficiency, magnesium depletion, thyroid dysfunction, or other metabolic irregularities.

For this reason, NeuroAffective-CBTยฎ encourages routine bloodwork early in therapy where possible, alongside collaborative working with GPs, endocrinologists, nutritionists, and even personal trainers when appropriate. CBT psychotherapists, clinical psychologists, and other doctoral-level therapists are not expected to function as nutritionists or physicians. Nevertheless, a working knowledge of the neurobiology of sleep, exercise, and nutrition is increasingly importantโ€”not only because these domains interface with the medicalโ€“disease model, but because disruptions in these systems are directly relevant to psychological treatment rather than peripheral โ€œwellbeing advice.โ€ Routine blood tests frequently reveal co-occurring issues such as low vitamin D, iron, or B-vitamin levels, as well as untreated or under-treated thyroid dysfunctions (Jacka, 2017). Recognising these patterns does not turn the psychotherapist into a medical prescriber, but it does allow for more informed questioning, clearer integration within case formulation and treatment planning, improved liaison with medical professionals, and compassionate normalisation for clients who struggle to understand why their emotional system may feel chronically overtaxed.

As Figure [2] illustrates, hormones exert a significant influence on how reactive, sensitive, and energised we feel. Cortisol and adrenaline underpin both acute and chronic stress states (McEwen, 2007), shaping irritability, hyper-alertness, and emotional overwhelm. Thyroid hormones, together with dopamine, regulate energy, drive, vitality, and cognitive clarity (Phillips, 2017), while sex hormones such as oestrogen and testosterone play central roles in emotional stability, motivation, confidence, and overall well-being. When these systems drift out of balance, whether through chronic stress, metabolic disturbance, or natural hormonal fluctuations, emotional sensitivity often increases and mood becomes more vulnerable to rapid shifts. Hormonal balance therefore contributes meaningfully to emotional regulation, although it is only one component within a broader regulatory system that also includes neurotransmitters such as serotonin (Serafini, 2012), lifestyle factors such as sleep, movement, and diet (Walker, 2017; Kandola et al., 2019), and learned psychological skills.


Figure [2]

Hormonal balance clearly shapes emotional sensitivity and reactivity.
Hormones are only one part of the regulatory system.


Within the TED model, micronutrients are therefore conceptualised as strategic adjuncts rather than foundations. When they are clinically indicated, medically monitored, and integrated into a comprehensive therapeutic plan, they can help stabilise the physiological terrain on which psychological intervention takes place. By pairing targeted micronutrient science with the core pillars of sleep, movement, and nutrition, TED supports a biologically grounded, holistic approach to emotional health that honours the bodyโ€“brain integration at the heart of NeuroAffective-CBTยฎ.

Ultimately, this integrated approach helps therapists distinguish between primarily psychological processes and biologically driven symptoms, and to incorporate both levels into their case formulation. Addressing relevant physiological imbalances alongside psychological work often makes treatment more efficient, precise, and sustainable, and offers clients a more coherent explanation for their difficulties and their recovery.

Implementation of TED within NeuroAffective-CBTยฎ

As noted earlier, TED is the third therapy module within the six-module NA-CBTยฎ structure: Assessment and Pendulum-Effect; Psychoeducation and Motivation; TED; the Integrated Self; Coping Skills; and Relapse Prevention. Although presented as separate headings, NA-CBTยฎ conceptualises the middle modules as overlapping and interchangeable. Clinicians are invited to move back and forth between them according to clinical priorities and the clientโ€™s readiness. The only fixed points are a thorough assessment at the start and a considered relapse-prevention phase at the end.

The Pendulum-Effect case formulation, introduced during assessment (Mirea, 2018a; Mirea, 2018b), is particularly relevant to TED. It conceptualises self-sabotaging strategies such as, comfort eating, excessive drinking, withdrawal, or overworking, as reinforcing patterns of self-neglect rather than failures of willpower. The formulation maps the dynamic interactions between core affect (e.g., shame, guilt, fear, anger, or disgust), shame-based beliefs and self-loathing narratives, and the maladaptive compensatory strategies of overcompensation, avoidance, and capitulation. It also highlights physiological vulnerabilities such as overeating and metabolic instability (Jacka, 2017), disrupted sleep from rumination (Mauss et al., 2013), and chronically low movement (Kandola et al., 2019). TED is woven through this formulation as both a target of change and a stabilising resource, addressing the physiological factors that maintain the pendulumโ€™s swing. A typical example might be: I overeat alone because it makes me feel better (overcompensation); nobody wants to see me anyway (capitulation); so I might as well stay home and avoid answering invitations or reaching out (avoidance). Over time, these oscillating patterns reinforce the very shame and self-loathing from which they originally attempted to protect.

In early sessions, assessment extends beyond symptoms and cognition to examine sleep patterns and circadian disruption (Walker, 2017), movement levels and physical conditioning (Craft & Perna, 2004), dietary habits and cravings (Inchauspe, 2023), and available medical information such as bloodwork and metabolic markers (Jacka et al., 2017). Given the rising incidence of metabolic difficulties across age groups, NA-CBTยฎ encourages collaborative relationships with healthcare providers and does not restrict itself to a purely psychological lens.

The psychoeducation and motivation module introduces clients to the Brain-Core Function model of prediction and protection (Mirea, 2018a), the Bodyโ€“Brainโ€“Affect triangle, and the role of sleep, movement, and diet in shaping emotional reactivity, cravings, and cognitive clarity (Walker, 2017; Kandola et al., 2019; Jacka, 2017). TED is framed as an inner friend or supportive internal coach who prompts daily self-checks (โ€œHow tired am I?โ€, โ€œHow much have I moved today?โ€, โ€œWhat have I eaten and drunk today?โ€). This externalises self-regulation in a non-shaming, accessible way and helps clients gradually internalise healthier habits.

Goals are then set collaboratively and intentionally kept small, concrete, and measurable. Adjusting bedtime by even twenty or thirty minutes, adding a brief daily walk, bringing forward the last meal of the day, or reducing one marked source of daily glucose spikes can all serve as early steps. These steps are framed as experiments rather than rigid rules, reducing pressure and allowing curiosity and learning to guide change.

Clients are encouraged to track sleep, movement, diet, mood, and cravings between sessions. These logs strengthen self-efficacy and help link physiological changes with emotional and cognitive patterns, supporting the collaborative empiricism at the heart of CBT (Hofmann et al., 2012). TED is then integrated with core CBT interventions such as behavioural activation, cognitive restructuring, exposure and response prevention, and mindfulness or compassion-based practices. As physiological stability improves, clients often find that cognitively and emotionally challenging work becomes more tolerable and more effective.

Applied Practice Examples

Clinical case material helps illustrate how TED operates in practice. One client presenting with volatile mood swings and intense shame spirals showed notable improvement after consistent work on sleep hygiene, including earlier bedtimes, a reduction in evening screen time, lighter evening meals, and increased daylight exposure in the morning. As sleep stabilised, emotional volatility decreased, and the client described feeling โ€œless on edgeโ€ and more able to engage with cognitive restructuring.

In another case, a client sought therapy for work-related stress and depression. Their pattern of skipping breakfast, relying on late-night dinners, and consuming multiple teas and coffees during the day contributed to fragmented sleep and reduced workplace efficiency. Tailored psychoeducation, alongside structured changes in sleep routine and meal patterns, led to markedly improved daytime productivity and better stress regulation within weeks. The clientโ€™s sense of self-efficacy also increased, making them more willing to address deeper beliefs about worth and failure.

TEDโ€™s exercise pillar also plays a role in craving regulation. Regular movement, even at modest levels such as brisk walking or light resistance training, often reduces sugar cravings and ruminative thinking within days. As insulin sensitivity improves and dopamine signalling becomes more stable, the learned association between emotional distress and sugary foods weakens. Clients report feeling less โ€œpulledโ€ towards certain foods and more capable of choosing alternatives that align with their values and health goals. Unplanned benefits often arise: modest weight loss, improved muscle tone, and enhanced physical confidence, all of which support self-appreciation and self-esteem. These early wins are framed not as pressure to โ€œdo moreโ€ but as evidence of the clientโ€™s growing strength and capacity to care for themselves.

Diet-related case examples also highlight the role of beliefs and expectations. In one instance, bloodwork revealed significant iron deficiency in a female client who had labelled her longstanding exhaustion, cognitive fog, and menstrual migraines as โ€œdepression.โ€ Psychoeducation about mood, physiology, and the impact of blood loss, combined with appropriate iron supplementation and dietary adjustments, led to marked improvements in energy, anxiety, and confidence over a relatively short period. A problem that had been experienced as a fixed psychological defect was reframed as a largely correctable biological imbalance embedded within a broader emotional context.

TED is particularly helpful in work with shame and self-loathing. In early sessions, clinicians explore these core affects and the resultant self-sabotaging strategies, framing them non-judgementally as understandable, historically adaptive patterns that once protected the client. Comfort eating, for example, may function as a pendulum-like oscillation between overcompensation and capitulation: โ€œI eat to feel better and I stay at home, safely away from people who I believe dislike me anyway.โ€ Excessive drinking, withdrawal, and overworking can operate through similar mechanisms of self-protection that inadvertently become self-neglect. TED enters here as a gentle, embodied pathway into change. When the โ€œmind and heartโ€ feel overwhelmed or intractable, TED redirects attention to the body, which can often be supported more immediately and predictably.

For clients apprehensive about trauma-focused work or deep exploration of shame, TED offers a stabilising starting point. As physiological dysregulation settles and concrete changes accumulate, more complex work, trauma processing, addressing entrenched shame, challenging self-loathing, or revising internalised narratives, becomes safer and less overwhelming. Clients begin to experience themselves as capable of caring for their bodies, which strengthens self-respect, reduces shame, and nurtures a more compassionate relationship with the self.

Implications for Psychotherapy Practice

The TED model offers a range of practical and conceptual advantages for clinicians seeking to integrate lifestyle science into psychotherapeutic work. By positioning sleep, movement, and diet as core regulatory mechanisms rather than secondary lifestyle factors, TED provides a clear framework for understanding how physiological states shape affect, cognition, and behaviour.

First, TED facilitates genuine lifestyleโ€“mental health integration. It invites clinicians to bring questions about sleep, activity, and diet into the heart of case formulation, particularly in cases where emotional dysregulation, chronic shame, or persistent anxiety have not responded sufficiently to cognitive or behavioural strategies alone. By stabilising the bodyโ€“brain system through targeted lifestyle adjustments, clients often become more receptive to therapeutic interventions and experience improvements in mood, concentration, and resilience that would be difficult to achieve through cognitive work alone.

Second, TED reframes cravings, whether for sugar, carbohydrates, emotional eating, alcohol, or even digital media, as learned, prediction-driven responses rooted in the brainโ€™s reward and metabolic systems. This reframing allows clinicians to normalise cravings rather than judge or pathologise them. Clients learn to see cravings as modifiable neuro-behavioural habits shaped by past learning and current physiology. Behavioural tools such as exposure, response prevention, and habit reversal can then be applied, alongside cognitive strategies for reappraising urges and anticipating triggering contexts, and physiological strategies for stabilising sleep and blood sugar.

Third, TED provides accessible psychoeducational language that demystifies complex neuroscience. Terms such as โ€œtired brainโ€, โ€œhungry amygdalaโ€, โ€œglucose crashโ€, โ€œall over the place hormones”, brain predicting threatsโ€, or โ€œinner TED coachโ€ help clients visualise how their physiological state influences their emotional reactions. This clarity typically reduces self-blame, increases motivation, and strengthens the therapeutic alliance. For many clients, TED becomes a daily reference point for self-regulation outside sessions.

Fourth, TED naturally supports motivational work by emphasising small, achievable, and trackable changes. Adjusting bedtime slightly, adding short movement breaks throughout the day, bringing a meal forward, or reducing a single high-glucose food can all be framed as experiments that accumulate into meaningful change. These micro-behaviours provide early wins that reinforce self-efficacy, particularly helpful for clients who feel overwhelmed, hopeless, or stuck in patterns of avoidance and self-criticism.

Fifth, TED aligns seamlessly with third-wave therapies such as ACT, DBT, mindfulness-based interventions, and compassion-focused approaches. It provides the physiological grounding for concepts like acceptance, values-based action, distress tolerance, present-moment awareness, and self-compassion. By stabilising physiological states, TED enhances clientsโ€™ capacity to engage in exposure, mindfulness exercises, grounding techniques, and metacognitive work, making psychological flexibility more accessible. At the same time, its explicit integration of neuroscience, lifestyle science, and biologically informed self-regulation positions TED, and NA-CBTยฎ more broadly, not only as compatible with third-wave approaches but as part of a developing fourth wave of CBT in which cognitive, behavioural, affective, and embodied interventions are more fully synthesised.

Finally, TED offers a framework for understanding and responding to the challenges of digital life. Sleep patterns, attention, cravings, and emotional processing are increasingly shaped by screens, notification systems, food delivery ecosystems, and AI-driven attention-capturing loops. TED enables clinicians to help clients explore how digital environments interact with the three pillars: late-night screen use disrupting sleep, sedentary work reducing movement, food delivery apps increasing access to high-glucose foods, and constant online stimulation affecting reward sensitivity and craving. In this way, TED remains relevant to emerging cultural and technological realities.

Using TED in Your Therapy Practice

Early Sessions: Assessment and Hypothesis Building
Dedicate some session time to a structured TED assessment. Map sleep patterns, movement levels, and dietary routines alongside internalised shame, self-loathing, overwhelming affect, and the clientโ€™s compensatory, avoidant, or capitulating strategies. Begin developing a hypothesis, such as the Pendulum-Effect formulation, linking physiological dysregulation with emotional volatility and behavioural coping.

Socratic dialogue should be gentle, curious, and function-focused, helping clients discover the purpose behind their patterns rather than defending against judgement. Useful questions include:

  • โ€œWhat does overeating or drinking give you in the short term?โ€
  • โ€œIf this behaviour is an overcompensation, what might it be protecting you from feeling?โ€ (overcompensation)
  • โ€œWhen you withdraw or drink alone, what emotion are you moving away from?โ€ (avoidance)
  • โ€œIs there a part of you that believes you deserve to feel bad or shouldnโ€™t ask for support?โ€ (capitulation)
  • โ€œWhere do you see yourself on the pendulumโ€”pushing hard, giving up, or avoiding?โ€
  • โ€œHow does poor sleep or unstable blood sugar shape your emotional reactions?โ€

These questions help uncover the oscillation between overcompensation, capitulation, and avoidance, and set the stage for how TED can stabilise the physiological base that supports emotional regulation.

Earlyโ€“Middle Sessions: Co-Creating Small, Concrete Experiments Introduce one small, achievable change in each TED pillar, tailored to the clientโ€™s readiness, needs, and physical ability. Collaboratively set goals and provide brief psychoeducation that links these changes to emotional regulation, metabolic stability, and bloodwork findings when available. Examples include:

  • Bringing bedtime forward by 20โ€“30 minutes, adapted to the clientโ€™s lifestyle, routines, and sleep challenges.
  • A 10-minute daily walk, structured movement break, or sports activity, chosen in line with the clientโ€™s interests, physical ability, and therapeutic goals.
  • Moving the last main meal earlier in the day, tailored to the clientโ€™s schedule and eating patterns, supported by psychoeducation about glucose regulation and relevant bloodwork findings.
  • Taking clinically appropriate supplements indicated by bloodwork (e.g., vitamin D, iron, omega-3, magnesium), always under medical guidance.
  • Reducing one predictable source of daily glucose spikes, such as sugary snacks, sugary drinks, or late-night eating.

Encourage the use of simple tracking tools, sleep logs, movement logs, food logs, or continuous/flash glucose monitors where appropriate, to build insight into how physiological shifts influence mood, cravings, and cognitive clarity. These tracking measures support collaborative empiricism and help normalise the link between daily habits and emotional regulation.

Middle Sessions: Linking Physiology to Emotion and Cognition
As clients log sleep, movement, diet, and cravings, use these patterns to illustrate how physiological stability supports emotional steadiness and cognitive flexibility. Help clients notice:

  • how improved sleep strengthens emotional tolerance
  • how regular movement reduces cravings and rumination
  • how steady glucose levels soften shame spirals and urgency
  • how nutritional changes affect mood, fatigue, and motivation

Socratic questions deepen insight:

  • โ€œWhat do you notice happens to your mood on days when you sleep better?โ€
  • โ€œHow does movement affect the intensity or duration of difficult feelings?โ€
  • โ€œWhat patterns do you see between your eating rhythms and your triggers?โ€

TED then becomes a living part of the formulation, showing how stabilising physiology enhances the effectiveness and tolerability of behavioural activation, cognitive restructuring, and exposure work.

Relapse Prevention: Embedding TED as a Long-Term Inner Coach
In the final phase, TED becomes a personalised self-regulation checklist and internal companion. Clients learn to ask themselves:

  • โ€œHow tired am I?โ€
  • โ€œHow much have I moved today?โ€
  • โ€œWhat have I eaten or drunk that might affect my mood?โ€

TED is framed as an inner guideโ€”protective, stabilising, and compassionateโ€”rather than a set of behavioural rules. Some clients benefit from using a literal teddy bear or symbol to anchor this internalisation.

In this way, TED supports long-term resilience by strengthening embodied awareness, preventing physiological drift, and sustaining the emotional stability needed for continued psychological growth.

Additional Socratic Questions

The following questions can be adapted depending on the clientโ€™s history, readiness, and goals.

Exploring Function and Purpose:

  • โ€œWhat does this behaviour give you in the short term?โ€
  • โ€œWhat does it help you avoid emotionally?โ€
  • โ€œWhat happens internally just before the behaviour starts?โ€
  • โ€œIf the behaviour could talk, what would it say it is trying to protect you from?โ€

Exploring Shame and Self-Loathing Underlayers:

  • โ€œWhat does this behaviour say about how you see yourself?โ€
  • โ€œIs there an old belief or story about yourself that gets activated here?โ€
  • โ€œIf someone you cared about struggled in this way, how would you interpret their behaviour?โ€

Exploring the Pendulum-Effect:

  • โ€œWhere do you notice yourself on the pendulumโ€”pushing hard, giving up, or avoiding?โ€
  • โ€œWhat triggers a shift from one end of the pendulum to the other?โ€
  • โ€œWhat would a more balanced middle position look like for you?โ€

Linking TED to Emotional Patterns:

  • โ€œHow does your sleep or lack of sleep influence how quickly you reach this behaviour?โ€
  • โ€œDo cravings or urges feel stronger on days when youโ€™ve eaten in a certain way?โ€
  • โ€œWhen your energy is low, which part of the pendulum do you tend to move toward?โ€

Building Insight and Motivation:

  • โ€œWhat would change if you had 10% more sleep or energy this week?โ€
  • โ€œWhich TED pillar feels easiest to adjust first?โ€
  • โ€œWhat small shift could help the pendulum swing less violently?โ€
  • โ€œWhich of these would feel like the smallest possible step forward?โ€
  • โ€œWhat would a 10% improvement look like this week?โ€
  • โ€œHow will we know if this experiment is helping?โ€

Limitations and Future Research

While TED is grounded in clinical practice and supported by an existing evidence base drawn from multiple disciplines, dedicated empirical evaluation of TED as a specific framework is still emerging. Future research should include randomised controlled trials comparing standard CBT with NA-CBTยฎ incorporating TED, as well as longitudinal studies tracking lifestyle changes and emotional outcomes over time (Hofmann et al., 2012). Mediation analyses exploring pathways such as improved sleep leading to reduced emotional reactivity (Mauss et al., 2013; Ben Simon et al., 2020) and enhanced self-esteem, or dietary change reducing inflammation and improving mood and cognition (Slavich & Irwin, 2014; Jacka et al., 2017), would be particularly valuable.

Cross-cultural and developmental studies are needed to examine the generalisability of TED across different age groups, cultural contexts, and health systems. Doseโ€“response investigations could clarify the intensity and duration of sleep, exercise, and dietary changes required to produce clinically meaningful improvements (Kandola et al., 2019; Walker, 2017). Mechanistic studies incorporating biomarkers such as inflammatory markers (Slavich & Irwin, 2014), insulin sensitivity indices (Jacka, 2017), microbiome profiles (Marx et al., 2017), and neuroimaging would help map the physiological pathways through which TED exerts its effects. Finally, further work is needed to evaluate micronutrients and supplements as adjuncts, rather than replacements, to psychotherapy and medication within an integrated neuroaffective framework (Marx et al., 2017; Juneja et al., 2024).

Conclusion and Clinical Caveats

NeuroAffective-CBTยฎ remains firmly anchored in the evidence-based strengths of traditional CBT. Its cognitive and behavioural techniques, long proven effective across a wide range of disorders (Hofmann et al., 2012), continue to form the backbone of therapeutic change. TED extends these foundations by highlighting a simple but often overlooked truth: psychological suffering does not occur independently of biology, and emotional healing does not unfold in isolation from the bodyโ€™s regulatory systems.

Hormones, neurotransmitters, metabolic processes, and sleepโ€“wake rhythms continuously influence how individuals feel, think, and relate. Cortisol affects stress sensitivity (McEwen, 2007); adrenaline heightens fear and readiness; oxytocin fosters bonding and trust. Thyroid hormones, oestrogen, and testosterone support mood stability, motivation, and energy (Phillips, 2017). At the same time, the brainโ€™s regulatory circuits, the prefrontal cortex, amygdala, hippocampus, and associated networks, govern moment-to-moment emotional responses through neurotransmitters such as serotonin, dopamine, GABA, and glutamate (Serafini, 2012). Within this landscape, TED fills a critical therapeutic gap by providing a framework that honours the dynamic interplay between biological foundations, affective patterns, learned psychological habits, and behavioural skills.

TED reminds us that hormones may set the stage, neurotransmitters may shape moment-to-moment emotional reactions, and thoughts and habits continually influence both. Emotional regulation arises from the integration of all these systems, not from any single one. By stabilising physiology, improving sleep quality, increasing movement, and optimising nutrition, clients gain access to greater cognitive flexibility, emotional steadiness, and healthier behavioural patterns. This embodied stability allows deeper therapeutic work to take root, including trauma processing, shame reduction, and the reshaping of entrenched beliefs.

As metabolic disturbance, sleep dysregulation, sedentary lifestyles, and nutritional deficiencies increase globally, psychotherapy can no longer afford to ignore the body. The future of effective mental health intervention lies at the intersection of brain, body, affect, and behaviour, exactly where TED is positioned. By integrating lifestyle science with neuroaffective principles, NeuroAffective-CBTยฎ represents an emerging โ€œfourth waveโ€ of CBT: neuroscience-informed, embodied, and responsive to the realities of modern living and one that may be understood philosophically as a movement towards more authentic living.

At the same time, it remains essential to emphasise that TED and related lifestyle interventions do not replace medical care or psychiatric treatment. Routine health checks and bloodwork, especially from adolescence onwards, are vital given rising rates of diabetes, metabolic disorders, and nutritional deficiencies. Supplements should remain adjunctive, ideally used under medical guidance, rather than replacing prescribed medication. TED is best understood as a self-regulation framework that invites clinicians and clients alike to recognise that meaningful psychological change is not purely cognitive; it is profoundly physiological.

By attending to how we sleep, move, and eat, we cultivate not only emotional resilience but also a more compassionate, empowered relationship with the Self. TED offers a concise yet comprehensive way of weaving sleep, movement, and diet into psychotherapy. It bridges neuroscience, lifestyle medicine, and cognitiveโ€“behavioural interventions in ways that are accessible to both clinicians and clients. Ultimately, TED encourages us to view physiology as the fertile soil in which psychological change grows, reminding us that lasting transformation is not only a matter of thought but of the whole embodied person.

TED Series – Part VIII: The Hidden Conversation: How Nutrition Shapes Emotional States


Daniel Mirea (October 2025)

Abstract

In this eighth instalment of the TED (Tiredโ€“Exerciseโ€“Diet) Series, we turn to the neuroscience of food and drink, how what we consume shapes emotional regulation, cognitive performance, and overall mental health. Food is not merely fuel; it is information – biochemical data moving continuously from gut to brain and back again, influencing motivation, focus, mood, and even how we learn and relate.

Introducing TED within the NA-CBTยฎ Framework

Within the NeuroAffective-CBTยฎ framework, TED (Tired, Exercise, Diet) functions as the biologically grounded scaffold of self-regulation that stabilises the Bodyโ€“Brainโ€“Affect triangle. Here, โ€œDโ€ for Diet is not a list of prohibitions or lifestyle prescriptions. It represents a set of neuro-behavioural levers capable of modulating dopamine, serotonin, immune signalling, circadian rhythm, and the vagus-mediated gutโ€“brain axis, the intricate โ€œwiring loomโ€ that connects body and mind (Mirea, 2023; Mirea, 2025).

Earlier instalments in this series examined the key physiological regulators that underlie emotional and cognitive balance:

โ€ข Creatine โ€“ cellular energy and motivation (Part I)
โ€ข Insulin Resistance โ€“ metabolic flexibility and mood (Part II)
โ€ข Omega-3 Fatty Acids โ€“ neuronal membrane integrity (Part III)
โ€ข Magnesium โ€“ stress buffering and neural inhibition (Part IV)
โ€ข Vitamin C โ€“ antioxidant defence and neurotransmitter synthesis (Part V)
โ€ข Sleep – the neurobiology of fatigue and recovery within the Tired pillar (Part VI)
โ€ข Exercise, Sport Science and Movement โ€“ strength and resilience (Part VII)

This final chapter focuses on Diet, how nutrition interacts with the emotional brain and how eating can steady the mind, foster neuroplasticity, and restore a coherent dialogue between body and affect. Each meal sends molecular messages, amino acids, fatty acids, micronutrients that speak directly to our emotional circuitry. If sleep restores and movement activates, diet sustains, it provides the biochemical landscape on which both rest and action depend.

Understanding this hidden conversation allows us to view nutrition not as restriction, but as regulation – a way of cultivating emotional steadiness and cognitive vitality through biochemical literacy. Within NeuroAffective-CBTยฎ, such literacy transforms eating from an automatic behaviour into an intentional act of self-alignment.

When Food Became Feeling

The Evolutionary Roots of Emotional Nutrition

The connection between what we eat and how we feel seems obvious at first glance. Food is survival, and the brain, natureโ€™s master regulator of survival, is inevitably obsessed with what we ingest. To keep us alive, it rewards us for consuming what nourishes and warns us against what harms. In that sense, emotions are communication tools: they push or pull us toward or away from things essential to survival. Pleasure tells us to approach; disgust tells us to avoid.

Emotions are central to every moment of our lives, shaping perception, decision, and meaning. Yet despite their importance, few of us truly understand where emotions come from or how deeply they intertwine the brain and body. Emotion is not a phenomenon that happens in the head alone; it is a full-body event, a conversation between neural circuits, hormones, muscles, and sensory organs (Huberman, 2023).

The scientific story of emotion stretches back centuries, from Darwinโ€™s early theories of universal emotional expression to modern neuroscience. Darwin (1872) proposed that emotions evolved as adaptive action programs, biologically embedded to guide behaviour and secure survival. This idea has since found robust confirmation in neuroimaging and behavioural research (Panksepp, 1998).

According to Dr Andrew Huberman, Professor of Neurobiology at Stanford University, the two most robust and universal emotional responses are approach and avoidance. When we encounter something we like for instance, a pleasant smell or taste, the correspondent behaviour is to lean in, inhale, and expand our posture to take in more of it. When we encounter something we dislike, our default behavioural response or instinct is to lean back, turn away, or even hold our breath, a remnant of ancient mechanisms that once protected us from ingesting toxins or inhaling pathogens (Huberman, 2023).

These primitive body movements reflect the underlying logic of emotion itself: a biological pushโ€“pull system that regulates approach and aversion. Deep brain structures such as the basal ganglia contain โ€œgoโ€ circuits that promote action and โ€œno-goโ€ circuits that inhibit it – mechanisms that operate beneath conscious awareness yet determine much of our emotional behaviour (Mirea, 2023; Huberman, 2023).

From this perspective, emotions are the brainโ€™s predictions about necessary actions in any given moment. They are not arbitrary feelings but dynamic signals that prepare the body to move, toward nourishment or away from threat. Food, therefore, sits precisely at this decision point. Taste, smell, interoception, and posture converge to produce motivation and choice.

Since the dawn of our species, emotion and nourishment have been partners in survival. The infantโ€™s first emotional learning arises through feeding: hunger, relief, pleasure, comfort. Long before we had words, flavour was communication. Even today, every bite still speaks to the nervous system – an unbroken dialogue between physiology and feeling.

In NeuroAffective-CBTยฎ, emotion is described as a bodyโ€“brainโ€“affect circuit. The body gathers sensory and chemical data; the brain interprets that data into feeling; affect then drives behaviour – approach or avoidance. Food is part of that loop. Each meal is both nutrition and information.

TED Takeaway: We do not just eat to live; we live through what we eat. Food is our first emotional language. Design your environment so that โ€œmove-towardโ€ cues lead you to the foods that truly support you. Make the right choice the easy choice!


The Gut: A Second Brain with Its Own Voice

How the Microbiome Speaks the Language of Emotion

Inside your abdomen lives a civilisation of roughly 39 trillion microorganisms, weighing about as much as your brain. Together, they form the gut microbiome, an ecosystem that digests food, manufactures vitamins, regulates immunity, and produces neuroactive chemicals such as serotonin and GABA, both of which directly influence mood, calmness, and emotional tone (Wei et al., 2022; Appleton, 2018).

Astonishingly, about 95% of the bodyโ€™s serotonin, often called the โ€œhappy chemicalโ€, is synthesised not in the brain, but in the gutโ€™s enterochromaffin cells (Wei et al., 2022). When this microbial community thrives, serotonin and GABA levels rise, helping the brain register safety and satisfaction. When inflammation, stress, or poor diet disturb the microbiome, the system tips into imbalance, and emotional symptoms often emerge as irritability, anxiety, or low mood (Appleton, 2018).

This intricate conversation between the gut and the brain travels along the vagus nerve, the bodyโ€™s longest cranial nerve, connecting the brain to nearly every major organ. It meanders from the brainstem through the chest to the intestines, touching the heart, lungs, and liver along its route. It is, in effect, the biological internet cable linking your internal organs to your emotional life. When the gut releases inflammatory or distress signals, the vagus nerve carries those alarms upward to the brain; when we breathe slowly, hum, sing, or chew mindfully, it transmits calm signals in the opposite direction (Lu et al., 2024).

But this communication is not purely chemical. Within the gut wall lies a network of neuropod cells, remarkable sensory units discovered by Dr Maya Kaelberer and colleagues at Duke University. These cells are equipped with electrical synapses that can detect nutrients such as glucose, amino acids, and fatty acids, and then send rapid signals directly to the brain (within milliseconds), to shape perception, emotion, and appetite (Kaelberer et al., 2018).

This discovery explains why the gut is sometimes referred to as the โ€œsecond brain.โ€ It does not merely digest; it perceives. The gut continuously samples the external world through food, drink, and bacteria and, informs the brain about what is safe, satisfying, or potentially harmful. It helps explain cravings, aversions, and the emotional resonance of eating. When you enjoy a morning coffee with a biscuit, the gutโ€™s chemical sensors are already communicating with your midbrain reward circuits, producing the pleasurable surge that fuels alertness and comfort.

In NeuroAffective-CBTยฎ, this gutโ€“brain dialogue embodies the biological foundation of interoceptive awareness, also known as, the ability to sense internal bodily states. When we practise mindfulness or direct calm, non-judgemental attention inward, we become more attuned to these subtle signals. Over time, this practice refines emotional regulation by aligning bodily feedback with cognitive understanding (Goldin and Gross, 2010; Mirea, 2024).

From the rectum to the oesophagus, this 9โ€“10 metre canal is not only our largest internal organ but arguably our most socially connected one, continually interpreting the external world through what we ingest and how we feel. As we begin to appreciate this complexity, we can see that mental health is not confined to the brain. It is a networked experience, a dialogue between neurons, microbes, and meaning.

TED Takeaway: When your gut talks, your brain listens. Nourish that conversation!


Good Bacteria, Bad Mood: The Microbiome and Depression

When Emotional Health Depends on Microbial Harmony

The phrase โ€œgut feelingโ€ has never been more literal. In recent years, neuroscience has confirmed what intuition long suspected, that our mental health depends not only on the chemistry of the brain but also on the ecology of the gut. The bacteria, fungi, and viruses that inhabit our intestines do far more than digest food; they influence emotion, immunity, and even identity. When that internal ecosystem becomes imbalanced, mood often follows.

Research has shown that people suffering from depression or chronic anxiety tend to have less diverse gut microbiomes, alongside a higher concentration of bacterial species that produce inflammatory metabolites (Kelly et al., 2016; Foster et al., 2021). These molecules can cross the bloodโ€“brain barrier, altering neurotransmitter balance and disrupting neural circuits involved in mood regulation. In a striking series of animal experiments, transferring gut bacteria from a depressed mouse to a healthy one was enough to induce depressive behaviours in the recipient (Zheng et al., 2016).

Early human studies echo these findings. In small clinical trials, faecal microbiota transplants (FMT) from non-depressed donors temporarily improved depressive symptoms in treatment-resistant patients (Valles-Colomer et al., 2019). While the idea of โ€œtransplanting happinessโ€ remains more metaphorical than practical, these results demonstrate a powerful biological truth: our emotional wellbeing is influenced by the microbial conversations happening below the diaphragm.

When the microbiome loses diversity, certain gut bacteria begin releasing pro-inflammatory cytokines, immune messengers that signal distress throughout the body. The brain interprets these signals as threat or fatigue, activating neural circuits associated with low mood, lethargy, and loss of pleasure. In this way, inflammation acts as a bridge between gut imbalance and emotional imbalance (Miller and Raison, 2016).

Conversely, cultivating a healthy and varied microbiome supports resilience. Factors that enhance microbial diversity include:

โ€ข A fibre-rich, plant-based diet with fermented foods and minimal ultra-processed ingredients.
โ€ข Regular aerobic exercise, which increases microbial species richness.
โ€ข Consistent sleep patterns, since gut flora follow circadian rhythms of their own.

The connection between gut health and depression is not just theoretical. The landmark SMILES trial (Jacka et al., 2017) demonstrated that a Mediterranean-style diet, rich in whole grains, legumes, vegetables, and olive oil, reduced depressive symptoms by about 30% within twelve weeks. Importantly, these improvements were independent of social support, confirming that what we eat can influence mood directly through biological pathways.

This evolving field, sometimes called nutritional psychiatry, reframes mental health as an ecosystem problem rather than a purely chemical one. As the NeuroAffective-CBTยฎ model suggests, emotional regulation is an embodied skill, a dialogue between body, brain, and affect (Mirea, 2023). The gut microbiome, communicating through the vagus nerve and immune signalling, is an active participant in that dialogue.

When we eat poorly, weโ€™re not just starving our bodies; weโ€™re silencing billions of microscopic allies whose job is to keep our minds in balance. Rebuilding that internal community is therefore not just a digestive act, it is an act of self-care, a physiological form of emotional literacy.

TED Takeaway: A healthy mind begins in a healthy gut. Diversity in your diet builds diversity in your emotions. Feed the bacteria that help you feel alive.


Feeding the Mind from the Inside Out

How Nutrition Speaks the Language of Emotion

If the gut is a second brain, then every meal is a message. What we eat doesnโ€™t just fill us, it informs us, shaping mood, motivation, and resilience through a constant biochemical dialogue between microbes and mind. In the NeuroAffective-CBTยฎ model, this represents the living interface between body, brain, and affect: the nutritional conversation that regulates how we feel and function (Mirea, 2023).

When we eat well, the gut microbiome flourishes. Beneficial bacteria such as Lactobacillus and Bifidobacterium convert dietary fibre and complex carbohydrates into short-chain fatty acids like butyrate, which reduce inflammation and support the integrity of the gut lining (Cryan et al., 2019). These molecules also cross into the bloodstream, where they influence brain chemistry, increasing serotonin and BDNF (brain-derived neurotrophic factor), both critical for stable mood and cognitive flexibility.

By contrast, processed foods rich in refined sugar and saturated fats feed inflammatory microbes, producing cytokines that weaken the gut barrier and signal distress to the brain (Miller and Raison, 2016). The emotional fallout can manifest as irritability, fatigue, and a sense of mental fog – the psychological shadow of biological inflammation.

The Role of Prebiotics and Probiotics

Two categories of food play an especially important role in nurturing the gutโ€“brain connection: prebiotics and probiotics.

Prebiotics are the fibres that feed beneficial bacteria, found abundantly in garlic, onions, oats, bananas, walnuts, and polyphenol-rich foods like olive oil, berries, and red grapes. Regular consumption of these foods maintains a diverse microbial population, strengthening the bodyโ€™s immune and emotional defences (Gibson et al., 2017).

Probiotics, by contrast, are the bacteria themselves, living microorganisms that, when consumed in sufficient quantities, support the health of the microbiome. These are found in fermented foods such as yoghurt, kefir, sauerkraut, miso, tempeh, and kombucha. When ingested regularly, probiotics can influence the production of neurotransmitters like GABA, the calming chemical that reduces anxiety and promotes relaxation (Sarkar et al., 2016).

Because of their measurable effect on mental health, some clinicians now call these organisms psychobiotics, living agents that support psychological wellbeing through the gutโ€“brain axis (Dinan et al., 2013).

Timing, Movement, and Mindfulness

Timing matters too. Probiotic capsules and fermented foods are most effective when taken on an empty stomach or before a light meal, allowing beneficial bacteria to pass through the stomachโ€™s acidic environment without being destroyed (Appleton, 2018).

Movement also plays a part. Aerobic exercise, brisk walking, cycling, swimming, improves microbial diversity, enhances vagal tone, and increases BDNF, reinforcing both mental and emotional resilience (Biddle et al., 2019). Likewise, consistent sleep supports microbial rhythms that align with the circadian cycle, anchoring energy and emotional stability.

Finally, mindfulness serves as the behavioural amplifier of this entire system. Paying attention to what and how we eat, slowing down, tasting, and breathing, activates the parasympathetic nervous system via the vagus nerve, enhancing digestion and emotional regulation. Mindful eating isnโ€™t a trend; itโ€™s neurobiology in action (Goldin and Gross, 2010).

The Emotional Ecology of Eating

Each meal is both nourishment and feedback. The brain interprets the gutโ€™s chemical and mechanical signals, fullness, acidity, nutrient quality, and translates them into emotion. When the body says safe, the mind feels calm. When the body says threat, the mind feels uneasy. Over time, the foods we choose either reinforce stability or erode it.

In this sense, food is not just nutrition; itโ€™s participation in a living ecosystem, one that rewards diversity, balance, and attention. The microbiome is not a silent partner; it is a dynamic community that mirrors how we live. A chaotic diet creates inner noise. A mindful one restores harmony.

TED Takeaway: Care for your microbes as you would a garden: feed them, move with them, let them rest. They return the favour with energy, clarity, and emotional balance. Mindfulness is not a trend; itโ€™s neurobiology in action.


Diet and Depression: What the SMILES Trial Taught Us

How Food Became a Form of Therapy

For decades, the relationship between food and mood has been treated as secondary, a lifestyle footnote rather than a therapeutic pathway. Yet emerging evidence now places diet at the centre of mental health. The food on your plate can influence neurotransmitters, inflammation, neuroplasticity, and ultimately, your emotional resilience.

The clearest demonstration of this came from Australia in 2017, when Professor Felice Jacka and her team published the landmark SMILES Trial (Supporting the Modification of lifestyle in Lowered Emotional States). The study asked a deceptively simple question:
โ€œCould changing oneโ€™s diet treat depression as effectively as conventional therapies?โ€.

A New Kind of Antidepressant

The researchers recruited adults diagnosed with major depressive disorder and divided them into two groups. One group received regular social support sessions, conversation, connection, and empathy. The other met with a dietitian who guided them through a modified Mediterranean diet, rich in vegetables, fruits, legumes, whole grains, fish, and olive oil, while minimising processed foods, sugar, and refined carbohydrates (Jacka et al., 2017).

After twelve weeks, the results were striking. The diet group showed a 32% reduction in depressive symptoms, compared to only 8% in the social-support group. Roughly one in three participants in the dietary intervention achieved full remission from depression, without medication changes.

Follow-up research (Opie et al., 2018; Lai et al., 2013) replicated these findings: when we nourish the brain with anti-inflammatory foods and micronutrients that enhance serotonin, dopamine, and BDNF, mood stabilises and cognition sharpens. The Mediterranean diet wasnโ€™t simply helping people feel better; it was changing their biology.

Why It Works: Inflammation and Neuroplasticity

The mechanism is now clearer. Diets high in refined sugar, processed fats, and artificial additives trigger systemic inflammation, increasing pro-inflammatory cytokines that interfere with neurotransmitter metabolism (Miller and Raison, 2016). Chronic inflammation dampens neuroplasticity, the brainโ€™s ability to form and strengthen neural connections, especially in regions like the hippocampus and prefrontal cortex, both vital for motivation and emotional regulation.

In contrast, Mediterranean-style diets are anti-inflammatory. They deliver omega-3 fatty acids, polyphenols, antioxidants, folate, and B-vitamins, all of which support synaptic growth, mitochondrial health, and neurotransmitter balance (Marx et al., 2017). Within days, high-quality nutrition can raise levels of BDNF, a protein that acts as fertiliser for neurons, improving learning, memory, and emotional flexibility (Andrรฉ et al., 2008).

In NeuroAffective-CBTยฎ, this biological process mirrors the therapeutic one: both involve rewiring, re-establishing communication between disrupted neural circuits. When inflammation drops and BDNF rises, the emotional brain becomes more responsive to therapy, mindfulness, and behavioural change (Mirea, 2023). Diet doesnโ€™t replace psychotherapy; it prepares the terrain for it.

Food as Behavioural Change

From a behavioural perspective, modifying diet is itself a neuroaffective intervention. Choosing whole foods over processed ones engages the prefrontal cortex, the brainโ€™s executive centre, and strengthens self-regulation circuits. This is the same cognitiveโ€“emotional skill that therapy trains: recognising impulses and acting intentionally. Each meal becomes an opportunity to practise regulation, reward delay, and self-care.

Moreover, eating well reinforces a positive feedback loop. Balanced blood sugar and nutrient-rich foods stabilise the autonomic nervous system, calming the vagus nerve and reducing emotional reactivity. Over time, people report not only better mood but also a greater sense of clarity and motivation, biological calm translating into psychological coherence.

The SMILES trial and subsequent studies remind us that emotional healing can begin with something as ordinary as lunch. A colourful plate may be the most accessible form of neurochemistry we possess.

TED Takeaway: Changing whatโ€™s on your plate can change whatโ€™s on your mind. Food is the most consistent, self-administered antidepressant youโ€™ll ever take.


Inflammation, Neuroplasticity, and the Healing Brain

How the Bodyโ€™s Chemistry Shapes the Mindโ€™s Resilience

For most of the twentieth century, depression was described as a chemical imbalance, a deficiency of serotonin, dopamine, or noradrenaline that could be corrected with medication. That model helped reduce stigma and offered effective treatments for many, but it left out something crucial: why those chemical imbalances occurred in the first place.

Over the past two decades, neuroscience has reframed this understanding. We now know that depression and anxiety are not simply deficits in neurotransmitters but disorders of connectivity and plasticity. In other words, the problem lies not only in the chemicals themselves, but in the wiring that allows brain cells to communicate (Duman and Duman, 2015; Serafini, 2012).

The Fire Within: How Inflammation Shapes Emotion

Inflammation is the bodyโ€™s ancient alarm system; a protective mechanism designed to fight infection and heal injury. But when the immune system becomes overactive through chronic stress, poor diet, or environmental toxins, this inflammation becomes systemic. Pro-inflammatory cytokines like IL-6 and TNF-ฮฑ flood the bloodstream and reach the brain, where they disrupt neurotransmission, reduce serotonin availability, and interfere with energy metabolism in neurons (Miller and Raison, 2016).

This inflammatory โ€œfogโ€ particularly affects the hippocampus and prefrontal cortex, regions crucial for motivation, memory, and self-reflection. Inflammation shrinks dendritic spines, weakens synapses, and slows the birth of new neurons, a process called neurogenesis (Kang et al., 2012). The result is a brain less capable of flexibility, learning, and emotional recovery.

But here lies the hopeful paradox: if the brain can become unwell through maladaptive plasticity, it can also heal through adaptive plasticity. The very circuits that fall silent under inflammation can reignite when nourished, exercised, and engaged through therapy.

Food as Neural Fertiliser

Anti-inflammatory diets, particularly Mediterranean-style nutrition, provide the building blocks for neuroplasticity. Omega-3 fatty acids, B-vitamins, folate, and antioxidants all contribute to the production of Brain-Derived Neurotrophic Factor (BDNF), a protein that promotes the growth and repair of synaptic connections (Andrรฉ et al., 2008).

In both humans and animals, increased BDNF correlates with reduced depressive symptoms and enhanced learning capacity (Duman and Duman, 2015). Even more striking, changes in BDNF can occur within days of improving diet, exercise, or sleep patterns (Serafini, 2012). Antidepressant medications, mindfulness training, and aerobic activity all elevate BDNF through similar pathways, demonstrating that biological and psychological interventions converge on the same neural mechanisms (Yang et al., 2016).

This overlap helps explain why the NeuroAffective-CBTยฎ model emphasises a multi-system approach: emotion, cognition, and physiology are not separate domains but parallel feedback loops. When diet reduces inflammation, therapy becomes more effective. When therapy enhances self-regulation, it reduces physiological stress. The brain heals through both bottom-up and top-down signals, food and thought working in tandem.

The Practice of Rewiring

In clinical terms, neuroplasticity means that the brain can literally change its structure in response to experience. New synapses form as we learn, and old, unused ones dissolve. This principle, โ€œneurons that fire together wire togetherโ€, describes both learning and healing.
Every act of mindful eating, exercise, or reframed thought in therapy strengthens certain circuits and weakens others. Over time, these microscopic changes accumulate into a macroscopic shift in emotional stability. Healing is not a switch; itโ€™s a training process, a gradual re-sculpting of the brainโ€™s networks through repeated experience.

From Inflammation to Integration

Understanding depression as an inflammatory and connectivity disorder allows us to see recovery as a process of integration, not correction. The goal is not to โ€œfixโ€ a broken brain but to create the conditions, nutritional, psychological, and relational, in which it can heal itself.

When inflammation subsides, BDNF rises, and neuroplasticity reawakens, the brain regains its natural rhythm of adaptation. The world begins to look different not because it has changed, but because the neural machinery perceiving it has been renewed.

TED Takeaway: Depression isnโ€™t just in your mind itโ€™s in your wiring. Reduce inflammation, nourish your brain, and practise new ways of thinking: thatโ€™s how neurons learn hope.


Energy, Glucose, and the Emotional Roller-Coaster

How Blood Sugar Shapes Behaviour and Mood

Every emotion has a metabolic signature. The brainโ€™s ability to focus, regulate mood, or recover from stress depends on a steady supply of energy, and that energy runs almost entirely on glucose. Yet, like a child on a sugar high, our modern diets deliver glucose in erratic bursts rather than balanced waves.
The result is what many of us recognise intuitively: the mid-morning energy crash, the irritability that accompanies hunger, or the brain fog after a sugary lunch. These are not signs of weak willpower but of metabolic turbulence – fluctuations in blood sugar that the brain interprets as emotional instability.

The Brainโ€™s Hunger for Balance

Although the brain represents only about 2% of body weight, it consumes nearly 20% of all glucose available in the bloodstream (Mergenthaler et al., 2013). Because it cannot store much energy, even brief drops in blood sugar can trigger fatigue, distractibility, or irritability. Conversely, sharp glucose spikes from refined carbohydrates or sweetened drinks cause transient dopamine surges followed by cortisol rebounds, leading to the emotional equivalent of a sugar hangover (Ludwig, 2002).

These rapid fluctuations affect the prefrontal cortex – the region responsible for self-control, focus, and emotional regulation. When glucose levels fall too low, this part of the brain becomes less efficient, and impulsive, reactive behaviours take the lead (Gailliot and Baumeister, 2007). In NeuroAffective-CBTยฎ terms, this is when cognitive regulation gives way to affective overwhelm, when physiology outpaces psychology.

The Glucoseโ€“Mood Connection

Clinical evidence supports this link. People with insulin resistance or poorly controlled blood sugar show higher rates of depression and anxiety, while those who stabilise glucose through diet and exercise experience improved mood and cognitive function (Luo et al., 2022). Chronic glucose variability increases oxidative stress and inflammatory cytokines, which impair both neuronal health and neurotransmitter balance โ€” especially serotonin and dopamine, the โ€œmood messengersโ€ that govern motivation and reward (Treadway and Zald, 2011).
In practical terms, mood stability often mirrors glucose stability. A diet rich in whole grains, fibre, protein, and healthy fats slows digestion and moderates glucose absorption. This prevents extreme highs and lows, sustaining steady energy to the brain throughout the day. The difference may feel subtle, fewer cravings, clearer thinking, a calmer baseline, but over time, these micro-adjustments translate into significant emotional resilience.

How to Flatten the Curve

Small, mindful habits can smooth the emotional and metabolic roller-coaster:

โ€ข Start the day savoury. A protein-based breakfast (e.g., eggs, yoghurt, or nuts) reduces morning glucose spikes and keeps dopamine stable through the first stressors of the day.
โ€ข Eat vegetables before starch. Fibre and phytonutrients slow carbohydrate absorption, flattening post-meal glucose peaks (Jovanovic et al., 2009).
โ€ข Walk for ten minutes after meals. Even light physical movement enhances insulin sensitivity and improves glucose uptake, translating into a calmer nervous system.
โ€ข Avoid โ€œnaked carbs.โ€ Pair carbohydrates with protein or fat to delay glucose release and prevent sharp insulin responses.

These strategies are not merely nutritional tricks, they are self-regulation tools. They train the body to maintain equilibrium, and the brain to interpret safety instead of scarcity.

From Sugar Spikes to Emotional Stability

When blood sugar stabilises, the bodyโ€“brainโ€“affect loop settles into coherence. The vagus nerve signals calm, the limbic system reduces alarm responses, and the prefrontal cortex resumes executive control. In this synchrony, the emotional brain becomes less volatile and more available for reflection, empathy, and learning, the core functions of psychological growth.

From a NeuroAffective-CBTยฎ perspective, managing glucose is a form of embodied mindfulness: paying attention to the bodyโ€™s energy patterns and adjusting behaviour to sustain internal balance. Itโ€™s not a diet; itโ€™s emotional literacy in biochemical form.

TED Takeaway: Flat glucose curves make flat emotional seas. Balance your blood sugar to balance your behaviour, stability in biology creates stability in being.


The Body Remembers What the Mind Forgets

Integration as the Final Language of Healing

By now it is clear that mental health is not confined to the skull. The mind is not a separate entity floating above the body; it is a conversation within it โ€” a continuous feedback loop between cells, organs, microbes, and meaning. Every thought has a heartbeat. Every emotion has a chemical echo.

In NeuroAffective-CBTยฎ, we call this the bodyโ€“brainโ€“affect triangle, a living system of regulation in which physiology, cognition, and feeling inform one another. When that dialogue is coherent, we experience emotional balance and clarity. When it breaks down through exhaustion, poor diet, or chronic stress, the body begins to speak in symptoms the mind may not yet understand.

The Biology of Memory and Emotion

The body remembers what the mind forgets because experience is not stored in words but in networks: of neurons, hormones, and sensations. Emotional memories, joy, fear, loss, are distributed across the nervous system, woven into posture, breathing, digestion, and sleep. Chronic inflammation, unstable glucose, or poor gut health can reactivate these circuits, producing what feels like psychological distress but is, in fact, physiological dissonance.

Conversely, when we restore the biological foundations of safety, balanced nutrition, restorative sleep, consistent movement, the same networks become available for reprocessing through therapy and reflection. The emotional brain can only heal when the body feels safe enough to listen.

This is why the TED framework (Tired, Exercise, Diet), is more than a lifestyle checklist. It is a neurobiological protocol for emotional coherence. By regulating fatigue, movement, and nutrition, we restore the stability that allows higher cognition – empathy, creativity, and self-awareness, to flourish (Mirea, 2023).

From Self-Regulation to Self-Understanding

Healing begins with self-regulation but matures into self-understanding. Each meal, each breath, each night of sleep becomes a message to the nervous system: You are safe enough to grow. When inflammation recedes, BDNF rises, and neural connections strengthen, therapy deepens. Mindfulness becomes easier. The world feels less like a threat and more like an invitation.

In this light, diet is not only about nutrients; it is about relationship with oneโ€™s body, with the environment, and with others. Sharing food, preparing it mindfully, and consuming it with gratitude engage ancient neural pathways of belonging and calm. The microbiome thrives not just on fibre and polyphenols but on human connection itself.

The Integration of Knowing and Feeling

Modern neuroscience and ancient wisdom converge on the same insight: we cannot think our way out of a dysregulated body. Emotional regulation begins in the viscera, in the gut that senses, the heart that signals, the breath that synchronises. The task of psychotherapy, then, is not to escape biology but to integrate it, to build bridges between inner experience and outer awareness.
When the mind listens to the body, and the body trusts the mind, coherence emerges. This is the moment when therapy, nutrition, and neuroscience meet, not as separate disciplines, but as languages of the same truth: that to feel well, we must live in alignment with what our biology has always known.

TED Takeaway: The state of your gut is the tone of your thoughts. Heal one, and the other learns to sing again.

TED Series, Part V: Vitamin C and Mental Health: Neurotransmitters, Stress, and Emotional Resilience

Daniel Mirea (October 2025)
NeuroAffective-CBTยฎ | https://neuroaffectivecbt.com


Abstract

In this fifth instalment of TED (Tiredโ€“Exerciseโ€“Diet) series, of the NeuroAffective-CBTยฎ project, we explore the multifaceted role of Vitamin C in mental health. Emerging evidence suggests optimal neurocognitive benefits occur at daily intakes of 200โ€“500 mg. Beyond its reputation as an immune booster, Vitamin C functions as a key modulator of neurotransmitter synthesis, oxidative stress, and immuneโ€“brain communication. Drawing on recent research in neuroscience, nutritional psychiatry, and psychoneuroimmunology, this article examines how Vitamin C supports emotional regulation, cognitive performance, and resilience under chronic stress. Integrating this evidence within the NeuroAffective-CBTยฎ (NA-CBT) framework, we highlight Vitamin C as a practical component of lifestyle-oriented psychotherapy, bridging nutrition, physiology, and affect regulation.


Introducing TED in the NeuroAffective-CBTยฎ Framework

The TED model (Tiredโ€“Exerciseโ€“Diet) synthesises neuroscience, psychophysiology, and behavioural science into an integrated scaffold for emotional regulation and biological stability. Within NeuroAffective-CBTยฎ, TED interventions are introduced early in therapy to restore homeostasis across the Bodyโ€“Brainโ€“Affect triangle, the physiological foundation of affective regulation, motivation, and self-concept (Mirea, 2023; Mirea, 2025).

Following earlier TED instalments on Creatine (Part I), Insulin Resistance (Part II), Omega-3 (Part III), and Magnesium (Part IV), this chapter focuses on Vitamin C, a micronutrient that bridges diet, stress, immunity, and cognition. Despite being essential to brain and body function, humans have lost the genetic capacity to synthesise Vitamin C, making dietary intake or supplementation critical for maintaining mental and metabolic health.


Evolutionary Context: A Necessary Deficiency

Unlike most mammals, humans lack the gulonolactone oxidase gene required for endogenous Vitamin C synthesis. Evolutionarily, this was likely pruned due to ancestral diets rich in fruits and vegetation (Harrison & May, 2009). Consequently, Vitamin C must be obtained through food, primarily fruits, vegetables, and, more recently, supplementation.

This evolutionary dependency aligns with human dietary anatomy: our dentition and digestive tract are optimised for plant-based, nutrient-dense foods rather than raw animal flesh. Thus, our reliance on Vitamin C-rich diets is biologically hardwired, linking nutrition directly to both immune and psychological resilience.

From a TED perspective, this represents a fundamental Dietโ€“Affect relationship: emotional and physiological stability rely on the consistent intake of nutrients we cannot make ourselves.


Vitamin C and Neurotransmitter Synthesis

Vitamin C plays a pivotal biochemical role in neurotransmitter regulation. It acts as a cofactor for dopamine ฮฒ-hydroxylase, the enzyme converting dopamine into norepinephrine (adrenaline), essential for motivation, attention, and stress response (Otte et al., 2016). It is also necessary for the metabolism of tryptophan into serotonin, the neurotransmitter most associated with emotional regulation and well-being (Young, 2020).

Low Vitamin C levels have been linked to reduced serotonin and norepinephrine activity, contributing to low mood, fatigue, and anxiety. In turn, adequate Vitamin C enhances the synthesis and stability of these neurotransmitters, improving energy and affective balance.

๐Ÿ’ก TED Translation:
Vitamin C acts as a โ€œbiochemical connectorโ€ in the Tired and Diet domains, fuelling the brainโ€™s ability to convert nutrients into emotion-regulating signals. When Vitamin C is low, dopamine and serotonin pathways slow down, leading to fatigue, irritability, and low resilience under stress.


Stress, Cortisol, and Oxidative Load

Vitamin C is among the most concentrated antioxidants in the brain and adrenal glands, the latter being the bodyโ€™s cortisol-producing centres. Chronic psychological or physical stress depletes Vitamin C rapidly, while low Vitamin C status impairs the bodyโ€™s ability to modulate cortisol output (Brody et al., 2002).

Experimental studies show that supplementation can reduce stress-induced cortisol elevations and improve mood under high-pressure conditions, such as academic or occupational stress (de Oliveira et al., 2015). The relationship is reciprocal: stress depletes Vitamin C, and deficiency heightens the physiological stress response.

๐Ÿ’ก TED Translation:
This is where Tired meets Diet: stress โ€œburns throughโ€ Vitamin C reserves, and depletion feeds back into higher cortisol and anxiety. Maintaining adequate Vitamin C helps keep the stress response efficient rather than overreactive.


Vitamin C, Immunity, and the Gutโ€“Brain Axis

Vitamin C supports both innate and adaptive immunity, promoting leukocyte function, barrier integrity, and antioxidant defence (Carr & Maggini, 2017). Its influence extends to the gutโ€“brain axis, the bidirectional communication between intestinal microbiota and the central nervous system.

Figure 1: The Vitamin Cโ€“Neurotransmitterโ€“Stress Interaction Loop

Deficiency in Vitamin C increases intestinal permeability (โ€œleaky gutโ€) and systemic inflammation, which can trigger neuroinflammatory cascades linked to depression and anxiety (Otte et al., 2016). Adequate Vitamin C intake may therefore modulate mood indirectly by maintaining gut integrity and reducing inflammatory load.

๐Ÿ’ก TED Translation:
Within TED, Vitamin C stabilises both the body and the mind, supporting the โ€œDietโ€ domain by maintaining gut health and the โ€œAffectโ€ domain by reducing the inflammatory signals that disrupt mood regulation.


Epigenetic and Cognitive Dimensions

Emerging research suggests Vitamin C contributes to epigenetic regulation, influencing DNA methylation and histone modification processes involved in early neurodevelopment and long-term emotional outcomes (de Beni et al., 2021).

High concentrations of Vitamin C are found in the brain and cerebrospinal fluid, particularly in the hippocampus and cortex, regions essential for memory and emotional learning. Even when blood levels fall, the brain retains Vitamin C preferentially, highlighting its role in preserving neurocognitive function under stress.

๐Ÿ’กTED takeaway:

Your brain treats Vitamin C like gold, it holds onto it even when the rest of your body runs low. Thatโ€™s because Vitamin C helps protect brain cells, supports memory, and keeps emotional circuits flexible under stress. New research shows that Vitamin C doesnโ€™t just work in the moment, it may even influence how certain genes involved in brain development and emotional balance get โ€œswitched onโ€ or โ€œoff.โ€ In simple terms, Vitamin C helps your brain stay adaptable, protecting your mood and mental sharpness over time. In TED language, vitamin C fuels both Diet and Affect, nourishing your brainโ€™s chemistry while helping it handle lifeโ€™s stress without burning out.


Clinical and TED Practical Guidance

Recommended dietary intake for adults is 75โ€“90 mg/day, but emerging data suggest higher doses (200โ€“500 mg/day) may optimise antioxidant and neurochemical benefits (Carr & Rowe, 2020).

Natural sources:

  • Citrus fruits (orange, lemon, grapefruit)
  • Kiwi, strawberries, papaya
  • Bell peppers, broccoli, spinach, kale

Supplementation:

  • Divide doses (e.g., 250 mg twice daily) for better absorption.
  • Combine with flavonoid-rich foods (e.g., berries, green tea) to enhance bioavailability.
  • Avoid smoking and chronic alcohol use, which accelerate Vitamin C depletion.

๐Ÿ’กTED Translation:
Think of Vitamin C as your brainโ€™s โ€œdaily maintenance nutrientโ€, keeping neurotransmitters balanced, inflammation low, and energy steady. Consistent intake, alongside sleep and exercise regulation, reinforces the biological base for emotional stability and therapeutic progress. This is such a vital hormone, clinicians may consider psychoeducating clients on Vitamin Cโ€™s stress-buffering role when addressing fatigue or anxiety, integrating nutritional discussions within TED-based behavioural activation plans.


Summary & Outlook

Vitamin C exemplifies the TED principle that emotional health begins with biological balance. It supports neurotransmitter synthesis, moderates stress responses, protects against oxidative damage, and sustains gut and immune integrity. Within NeuroAffective-CBTยฎ, Vitamin C functions as both a preventive and adjunctive intervention, enhancing emotional resilience and amplifying the effects of psychotherapeutic change.

Like Omega-3, Magnesium, and Creatine in earlier TED modules, Vitamin C represents a key neuro-metabolic pathway where diet and mood converge. However, supplementation should never replace clinical care, it must be introduced under professional guidance and viewed as a supportive component of comprehensive mental health treatment.

Emerging evidence suggests that optimal neurocognitive benefits occur at daily intakes of 200โ€“500 mg of slow release (or time release) Vitamin C, the type that stays longer in the system. Future research should explore Vitamin C supplementation within structured TED protocols for mood, stress, and cognitive disorders, bridging nutritional neuroscience with applied behavioural interventions.

Abstract

In this fourth instalment of the TED (Tiredโ€“Exerciseโ€“Diet) Series, we explore magnesium, an essential mineral often overlooked in discussions of mood, stress, and emotional regulation. Drawing from neuroscience, nutritional psychiatry, and the NeuroAffective-CBTยฎ framework, this article examines how magnesium supports brain function, sleep, and affective stability. It highlights evidence linking low magnesium levels to stress sensitivity, anxiety, and depression, and outlines how restoring magnesium balance may enhance emotional resilience, cognitive clarity, and therapeutic responsiveness.


Introducing TED in the NeuroAffective-CBTยฎ Framework

The TED (Tiredโ€“Exerciseโ€“Diet) model integrates neuroscience, psychophysiology, and behavioural science to restore balance across the Bodyโ€“Brainโ€“Affect triangle central to emotional health. Within NeuroAffective-CBTยฎ, TED interventions target the biological underpinnings of affective instability, fatigue, sleep disruption, poor diet, and chronic stress (Mirea, 2023; Mirea, 2025).

Following earlier TED instalments on Creatine (Part I), Insulin Resistance (Part II), and Omega-3 Fatty Acids (Part III), part IV turns to Magnesium, the quiet stabiliser of the nervous system. Though often overlooked, magnesium deficiency is widespread and increasingly recognised as a modifiable factor in stress, anxiety, and mood disorders. Despite its importance, subclinical magnesium deficiency affects an estimated 60โ€“70% of adults, with even higher rates observed in those under chronic stress or psychological strain (Maguire, 2018).


Magnesium and the Stress Response

Both physical and emotional stress, common in our multi-tasking, always-connected society, rapidly drain the bodyโ€™s magnesium stores. Research shows an inverse relationship between cortisol and magnesium levels: the higher the magnesium, the lower the cortisol (Takase et al., 2004). In turn, chronic stress accelerates magnesium loss through the urine and cellular loss, a process that weakens the bodyโ€™s ability to recover, creating a self-perpetuating loop of tension, fatigue, and anxiety.

In controlled studies, adrenaline infusions have been shown to rapidly and persistently reduce serum magnesium, with levels remaining low even after stress hormones subside (White et al., 1992). Observational data echo this: students under exam stress and soldiers anticipating conflict both show sharp declines in magnesium concentrations, particularly in red blood cells (Takase et al., 2004).

Environmental and sensory stressors such as noise exposure also increase magnesium loss through urine, lasting up to 48 hours post-exposure, suggesting that both psychological and physical stressors drain the same metabolic reserve.

TED translation: This is where Tired meets Diet, stress burns through magnesium, and low magnesium magnifies stress sensitivity, forming a self-perpetuating loop of fatigue and emotional tension.


Mechanisms: How Stress and Sleep Deplete Magnesium

During acute stress, the fight-or-flight response mobilises magnesium from cells into the bloodstream to support energy production and neuromuscular activity. However, prolonged or repeated stress leads to excretion rather than recycling, gradually lowering the bodyโ€™s magnesium reservoir.

Cortisol intensifies this cycle by stimulating the kidneys to excrete more magnesium, while inflammatory stress hormones further impair intestinal absorption. Over time, this results in lower intracellular magnesium in tissues such as muscle, brain, and heart, correlating with symptoms of tension, irritability, and restlessness.

Chronic sleep loss compounds the problem. Both short-term and long-term sleep deprivation reduce red blood cell magnesium levels, impairing vascular flow and contributing to the โ€œwired but tiredโ€ pattern common in anxiety and burnout (Takase et al., 2004).

Magnesium and Mental Health: Depression, ADHD, and Brain Aging

Magnesium and Depression

Epidemiological data from the National Health and Nutrition Examination Survey (NHANES) show that adults with the lowest magnesium intake have significantly higher rates of depression, particularly younger adults (Jacka et al., 2009).

A 2019 meta-analysis of 11 studies found that people with the lowest magnesium consumption were 81% more likely to experience depression than those with the highest (Derom et al., 2019).

Mechanistically, magnesium supports serotonin function, reduces neuroinflammation, and stabilises the excitatoryโ€“inhibitory balance of the brain, aligning with TEDโ€™s goal of calming hyperaroused affective circuits.

Magnesium and ADHD

Around 90% of individuals with ADHD show suboptimal magnesium levels, which correlate with irritability, restlessness, and sleep issues. Supplementing magnesium glycinate (125โ€“300 mg/day) for 4โ€“6 weeks can reduce symptoms and may even ease stimulant-related side effects.

Magnesium, Cognition, and Brain Aging

Recent research using UK Biobank data (n = 6,000) found that individuals with higher dietary magnesium intake (~550 mg/day) had larger grey matter and hippocampal volumes than those consuming ~350 mg/day, roughly the RDA (Peterson et al., 2023). These structural differences may reflect slower brain aging, roughly equivalent to one year of preserved neural integrity.

Complementary studies link higher magnesium intake to a lower risk of dementia and mild cognitive impairment in older adults, especially women (Yary et al., 2016). Magnesiumโ€™s neuroprotective effects likely stem from reducing oxidative stress, enhancing synaptic plasticity, and maintaining mitochondrial efficiency.


Magnesium and Sleep Physiology

Magnesium supports the onset and maintenance of sleep by activating GABAergic pathways and regulating melatonin synthesis. Randomised trials and meta-analyses show mixed outcomes likely due to differences in baseline magnesium status among participants, but studies consistently find that deficient individuals experience improved sleep quality following supplementation (Abbasi et al., 2012).

TED translation: Magnesium supports Tired by enhancing sleep restoration, Exercise by improving muscle relaxation, and Diet by regulating the energyโ€“stress feedback loop that shapes mood and focus.


Forms, Absorption, and Co-Nutrients

Not all magnesium forms are equally effective:

  • Best absorbed: Magnesium glycinate, citrate, malate, and L-threonate.
  • Less effective: Magnesium oxide (low absorption, laxative effect).

Optimise absorption by:

  • Taking magnesium with meals that include healthy fats or carbohydrates.
  • Co-supplementing vitamin D3 and vitamin B6, which enhance uptake.
  • Using divided doses throughout the day.
  • Avoiding enteric-coated capsules that delay intestinal release.

Magnesium L-threonate, in particular, crosses the bloodโ€“brain barrier and supports learning, memory, and synaptic density (Slutsky et al., 2010).

โš–๏ธ Dosage and Clinical Application

Target symptomRecommended formTypical dosageNotes
General stress / anxietyMagnesium glycinate or citrate250โ€“400 mg/daySplit doses with meals
Sleep disturbanceMagnesium glycinate or citrate200โ€“300 mg before bedEnhances relaxation
ADHD (children/adolescents)Magnesium glycinate powder125โ€“300 mg/dayGentle, better tolerated
Cognitive performanceMagnesium L-threonate1โ€“2 g/day (elemental Mg โ‰ˆ 150 mg)Crosses bloodโ€“brain barrier

Therapeutic effects typically take 3โ€“4 weeks as intracellular magnesium levels gradually normalise.

๐Ÿ’ก TED Translation

In TED terms:

  • Tired: Magnesium restores cellular energy and supports sleep recovery.
  • Exercise: Adequate magnesium improves muscle performance, oxygen delivery, and recovery.
  • Diet: Replenishing magnesium reduces stress reactivity and emotional fatigue.

Together, these effects stabilise the Bodyโ€“Brainโ€“Affect system, preventing the physiological overload that fuels shame-based and affective dysregulation.


Summary & Outlook

Magnesium is a cornerstone of emotional and metabolic balance. Chronic stress, disrupted sleep, and processed diets have created widespread deficiency that quietly undermines mental health.

Evidence now supports magnesium as a low-cost, physiologically synergistic intervention for anxiety, ADHD, depression, and stress-related fatigue. Within the NeuroAffective-CBTยฎ framework, it complements psychotherapeutic change by restoring the biological foundations of calm, focus, and resilience. When combined with structured TED interventions, consistent sleep, regular movement, and nutrient-dense meals, magnesium reinforces the physiological stability needed for enduring psychological growth.

Future directions include evaluating magnesium supplementation within integrated TED protocols for mood and stress-related disorders, bridging nutritional neuroscience with applied cognitive-behavioural intervention research.

TED Series, Part III: Omega-3 and Mental Health.

New Research Findings and NeuroAffective-CBTยฎ Implications

In this third instalment of the TED (Tiredโ€“Exerciseโ€“Diet) Series, we explore how omega-3 fatty acids, particularly EPA and DHA, influence mood, cognition, and emotional regulation. Drawing from neuroscience, nutritional psychiatry, and the NeuroAffective-CBTยฎ framework, this article examines the growing evidence that dietary fats do more than protect the heart, they also nourish the mind. Blending practical TED applications with current clinical research, it offers clinicians and readers accessible strategies for integrating omega-3s into a new lifestyle-based approach to mental health.

Introducing TED in the NeuroAffective-CBTยฎ Framework

The TED (Tiredโ€“Exerciseโ€“Diet) model brings neuroscience, nutritional psychiatry, psychophysiology, and behavioural science into an integrated framework for emotional regulation and mental health. Within the broader NeuroAffective-CBTยฎ (NA-CBT) programme, TED is introduced early to support self-regulation and biological stability, the โ€œBodyโ€“Brainโ€“Affectโ€ triangle that underpins shame-based and affective disorders (Mirea, 2023; Mirea, 2025).

Earlier parts of this series explored the roles of creatine and insulin regulation in mood and cognition. This third instalment turns to omega-3 fatty acids, essential nutrients that play a central role in brain health, mood regulation, and anti-inflammatory balance.


Why Omega-3s Matter: The Brainโ€™s Structural Fat

When people hear the word โ€œfat,โ€ they often think of storage fat the kind that accumulates around the waist or organs. But the brain depends on an entirely different type: structural fat, which makes up the cell membranes of neurons. These membranes control how signals and chemicals move between brain cells, and their flexibility directly affects how efficiently neurons communicate (Huberman, 2023).

Omega-3 fatty acids, primarily EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are the building blocks of these membranes. DHA maintains the structure of neurons, while EPA modulates inflammation and neurotransmission, influencing serotonin and dopamine signalling (Freeman et al., 2006; Mocking et al., 2020).

From a TED perspective, this is where Diet meets Affect: better membrane health and lower inflammation translate into improved emotional regulation, resilience to stress, and more stable mood patterns.

๐Ÿงฌ What Are EPA and DHA? (In Simple Terms)

When we talk about omega-3 fatty acids, weโ€™re mostly referring to two main types that the body uses for brain and heart health:

  • EPA (Eicosapentaenoic Acid): Think of EPA as the firefighter in your system. It helps reduce inflammation, calm overactive stress responses, and balance the brainโ€™s chemical messengers that affect mood. Studies show that getting enough EPA can help lift low mood and reduce symptoms of depression.
  • DHA (Docosahexaenoic Acid): DHA is more like the architect of your brain. It builds and maintains the structure of your brain cells, especially in areas responsible for memory, focus, and emotional stability. Itโ€™s crucial for brain development, but also for keeping adult brains flexible and resilient under stress.

Both EPA and DHA work together , EPA helps your brain feel better, and DHA helps it work better. You can get them from oily fish like salmon, sardines, and mackerel, or from algal oil if you follow a plant-based diet.

๐Ÿ’ก TED Translation:
EPA supports the Diet part of TED by reducing emotional inflammation, those biochemical โ€œstormsโ€ that make you feel tense or flat. DHA supports the Tired part, helping your brain stay sharp and recover faster when youโ€™re mentally drained. Together, they strengthen the brainโ€“body connection that TED and NeuroAffective-CBTยฎ aim to restore. It is important to note that these supplements do not cure mental health conditions but can operate as adjuncts to therapy and medication, supporting recovery and prevention.


๐Ÿ”ฌ Evidence from Research: Depression, Focus, and Emotional Health

EPA and Depression – What Research Shows

A growing number of studies show that omega-3 supplements rich in EPA (about 1 gram per day) can noticeably reduce symptoms of depression. In some cases, the improvements are similar to those seen with common antidepressant medications in people with mild to moderate depression (Peet & Horrobin, 2002; Martins, 2009; Mocking et al., 2020).

One major study compared 1 gram of EPA to fluoxetine (Prozac), a widely used SSRI antidepressant and found that both worked equally well in improving mood. The group that combined EPA and fluoxetine together did even better, suggesting that omega-3s may enhance the effects of antidepressant treatment (Nemets et al., 2006).

Scientists believe EPA helps mood in several ways. It reduces inflammation in the body and brain (which can interfere with mood-regulating chemicals like serotonin) and keeps brain cell membranes flexible, allowing signals to travel more efficiently between neurons (Su et al., 2018).

๐Ÿ’ก TED Translation:
In TED terms, EPA acts like a โ€œmood stabiliserโ€ for the bodyโ€“brain system, calming internal inflammation, improving brain energy flow, and helping emotions move more smoothly through the day.

DHA and Cognition – The Brainโ€™s Structural Support

While EPA helps regulate mood and inflammation, DHA focuses more on the structure and performance of brain cells. Itโ€™s especially concentrated in brain areas responsible for memory, focus, and emotional balance, such as the prefrontal cortex and hippocampus.

Research shows that people who get enough DHA perform better on memory and attention tasks, particularly older adults or those who normally eat little fish or other omega-3 sources (Yurko-Mauro et al., 2010). DHA helps brain cells maintain flexible outer membranes, allowing them to communicate efficiently and adapt to new information, a process linked to learning and resilience.

When DHA levels are low, brain signalling can become sluggish, affecting concentration, motivation, and even emotional stability. Regular intake through food (like oily fish) or supplements can help restore this โ€œneural flexibility.โ€

๐Ÿ’ก TED Translation:
In TED language, DHA supports the Tired and Diet domains, it helps the brain stay sharp, focused, and emotionally steady, especially under mental fatigue or stress. Think of it as giving your neurons the healthy fat insulation they need to keep your thoughts and emotions running smoothly.


โš–๏ธ Dosage, Ratios, and Practical Guidance

Most research suggests that taking between 1,000 and 2,000 mg per day of omega-3 fatty acids, especially formulations higher in EPA, can noticeably improve mood, focus, and general wellbeing (Martins, 2009; Mocking et al., 2020). For depression and emotional balance, experts often recommend that EPA make up at least 60% of the total omega-3 blend.

You can get these healthy fats from both food and supplements:

  • ๐ŸŸ Natural sources: oily fish such as salmon, sardines, mackerel, and anchovies.
  • ๐ŸŒฑ Plant-based options: chia seeds, flaxseed, walnuts, and algal oil (a vegan source rich in DHA).
  • ๐Ÿ’Š Supplements: choose products that are molecularly distilled or third-party tested for purity and heavy-metal safety.

Because omega-3s are fat-soluble, they are best absorbed when taken with meals that include some healthy fat, such as avocado, eggs, or olive oil.

๐Ÿ’ก TED Translation:
Omega-3s are like the high-quality oil in your brainโ€™s engine, helping neurons glide, communicate, and self-repair. For best results, pair consistent intake with the other TED elements: regular sleep (Tired), sports (Exercise), and nutrient-dense meals (Diet).


TED Practical Layer: Combining Nutrition with Behaviour

The TED approach is about how we live, not just what we take. Omega-3s work best when integrated into daily habits that support absorption, brain function, and emotional balance.

Here are a few practical ways to make that happen:

  1. Take omega-3s with meals that contain healthy fats.
    These fats, like those from eggs, olive oil, or avocado, help your body absorb EPA and DHA more efficiently.
  2. Pair with regular movement.
    Exercise increases enzymes that help omega-3s get into brain cells (Dyall, 2014). Even short daily walks or light strength training enhance this process.
  3. Balance omega-6 intake.
    Many modern diets contain too much omega-6 (from seed oils and processed foods), which can block omega-3 benefits. Aim for a lower omega-6 to omega-3 ratio (around 3:1) to reduce inflammation and support mood regulation (Simopoulos, 2016).
  4. Track mood and focus.
    Keep a brief weekly log of your energy, sleep, and emotional stability. Over a month or two, most people notice more mental clarity and steadier mood.

๐Ÿ’ก TED Translation:
Small, consistent actions matter. Taking omega-3s in the morning, walking regularly, and eating real, unprocessed foods all work together to open up the bodyโ€“brainโ€“affect loop, the very system TED aims to strengthen.

TED and NeuroAffective-CBTยฎ Integration

In the NeuroAffective-CBTยฎ (NA-CBT) framework, the TED model (Tired, Exercise, Diet) bridges the gap between the mind and body. Omega-3 supplementation fits naturally within the Diet domain, but its effects ripple across all three.

Low omega-3 levels have been linked to mood dysregulation, impulsivity, and emotional reactivity โ€” all central features of the bodyโ€“brainโ€“affect triangle that NA-CBT helps regulate (Mirea, 2025). Supporting neuronal health through dietary means therefore complements core CBT processes such as emotional awareness, behavioural activation, and self-compassion.

For clinicians, this integration can be structured through a few evidence-informed steps:

  1. Screen for dietary insufficiency or inflammation markers (e.g., high omega-6 intake, poor diet quality).
  2. Psychoeducate clients on the bodyโ€“mind connection โ€” explain how stabilising the bodyโ€™s biochemistry supports cognitive flexibility.
  3. Encourage gradual habit stacking, introducing omega-3s alongside TED routines (sleep hygiene, consistent exercise).
  4. Monitor outcomes, tracking not just mood changes, but energy, focus, and emotional resilience.

๐Ÿ’ก TED Translation:
Think of omega-3s as emotional lubricants, subtle but powerful agents that help the brainโ€™s communication systems run smoothly, making it easier for CBT tools to โ€œclick.โ€ Combined with good sleep and movement, they form part of a whole-person therapy that builds physiological and psychological balance from the inside out.


Summary & Outlook

The evidence around omega-3 fatty acids, particularly EPA and DHA, continues to grow, positioning them as safe, low-cost, and biologically plausible adjuncts for improving mood, cognition, and emotional regulation. In depression, EPA-dominant formulations (~1 g/day) have demonstrated antidepressant effects comparable to SSRIs in mild-to-moderate cases (Nemets et al., 2006; Mocking et al., 2020). DHA, on the other hand, plays a structural and neuroprotective role, supporting long-term cognitive resilience.

From the TED viewpoint, omega-3s bridge physiology and psychology. They not only support neuronal efficiency but also improve the emotional flexibility required for therapeutic change โ€” embodying TEDโ€™s principle that lifestyle science and psychotherapy are most effective when integrated.

Within the TED (Tiredโ€“Exerciseโ€“Diet) framework, omega-3s exemplify how dietary micro-interventions can amplify psychotherapeutic outcomes. Combined with good sleep, consistent exercise, and emotional processing, the three TED pillars, they help restore the physiological stability necessary for deeper psychological change.

For clinicians, the takeaway is practical:

  • Screen for dietary quality and omega-3 intake early in assessment.
  • Encourage balanced omega-3 to omega-6 ratios.
  • Integrate nutritional strategies alongside CBT interventions.
  • Track progress using both subjective (mood, focus) and objective (diet logs) measures.

๐Ÿ’ก Final Thought (TED Translation):
Omega-3s donโ€™t just feed the body, they fuel the brain. When woven into the TED lifestyle and NeuroAffective-CBTยฎ framework, they help restore energy, sharpen thinking, and smooth the emotional landscape, supporting the long-term goal of mindโ€“body regulation.
