Opening: Keto, Mental Health, and a Bold Claim
The episode opens with Ede’s assertion that ketogenic diets can rapidly reduce anxiety and even induce remission in severe mental illnesses. Steven introduces her as a Harvard‑trained psychiatrist pioneering nutrition‑based treatment in psychiatry, and she briefly recounts her own health collapse and counterintuitive dietary recovery.
- •In a clinical series, 43% of patients with bipolar, major depression, or schizophrenia reached remission on a ketogenic diet; 64% reduced psychiatric meds.
- •Ede’s own early‑40s health decline (fatigue, IBS, anxiety, depression) resolved on a diet opposite to standard guidelines: low‑carb, high‑fat, animal‑focused.
- •Her experience drove her into years of independent study of nutrition science focused on brain health.
- •Nutrition strategies can yield mood, cognition, and productivity gains in days to weeks when targeted correctly.
- 7:10 – 13:00
What Is Metabolic Psychiatry?
Ede defines her field, metabolic psychiatry, as the study of how food and metabolism affect brain function and mental health. She contrasts this emerging framework with the traditional ‘chemical imbalance’ narrative and introduces inflammation, oxidative stress, and insulin resistance as core drivers of psychiatric disorders.
- •Metabolic psychiatry was coined ~5+ years ago by Dr. Shebani Sethi at Stanford.
- •Traditional psychiatry frames mental illness as chronic, mysterious, and incurable, managed with lifelong meds and therapy.
- •Newer research highlights brain inflammation, oxidative stress, and insulin resistance as primary pathophysiological drivers.
- •These metabolic insults are strongly shaped by diet, environment, and lifestyle, not just genetics.
- 13:00 – 25:00
From Conventional Psychiatrist to Nutrition Specialist
Ede walks through her academic training and first decade as a conventional psychiatrist focused on meds and psychotherapy. She explains how repeated clinical disappointment and her own health crisis led her to re‑examine the role of nutrition in mental health, which had been largely absent from her medical education.
- •Background: biology degree, diabetes research, medical school at University of Vermont, Harvard psychiatry residency; 25 years in practice.
- •Medical school included only 2–3 hours of nutrition lectures; residency had none linking food to brain health.
- •Despite best efforts, most patients did not significantly improve on standard care—mirrored by senior colleagues’ experience.
- •Her personal trial‑and‑error food journal (2007) led to an animal‑heavy, low‑carb diet that resolved both physical and previously ‘normal’ mental symptoms.
- 25:00 – 37:40
The Diet That ‘Should Have Killed Me’ but Healed My Brain
Ede describes the specific diet that transformed her health and why it seemed to contradict everything she’d been taught. She then outlines how years of independent study into the primary research reshaped her understanding of red meat, whole grains, and plant foods, culminating in the three core nutritional principles in her book.
- •Her effective diet: mostly meat and seafood, low‑carb, low‑fiber, high‑fat; no whole grains or legumes; minimal plants.
- •It resolved chronic fatigue, IBS, fibromyalgia‑like pain, migraines, and seasonal depression while improving daytime energy and anxiety.
- •She initially considered recommending it reckless, so she immersed herself in primary nutrition science and a Harvard School of Public Health course.
- •She emphasizes the ‘power of subtraction’: removing harmful foods (e.g., refined carbs, seed oils) often matters more than adding superfoods.
- •Her three principles for brain nutrition are formulated: nourish, protect, energize.
- 37:40 – 46:20
Universal Principles: Nourish, Protect, Energize
Ede elaborates on the three foundational principles that she believes apply to all humans. She argues that a brain‑healthy diet is by definition body‑healthy, must include some animal foods, must remove pro‑inflammatory ingredients, and must maintain low, stable glucose and insulin for optimal brain energy.
- •Nourish: deliver all essential nutrients in whole‑food form; without supplements or fortified products, this is not achievable on a purely plant‑based diet.
- •Protect: remove foods that trigger inflammation and oxidative stress (chiefly refined carbohydrates and industrial seed oils).
- •Energize: ensure the brain has steady, clean fuel by controlling glucose and, crucially, insulin; insulin resistance undermines brain energy.
- •These rules are universal for cells, but application is personalized based on metabolism, age, activity, conditions, and preferences.
- 46:20 – 57:20
Personalizing Diet: Metabolic Health, Tolerances, and Environment
The discussion turns to individual variability: everyone’s cells need the same core nutrients and protection, but people differ in carbohydrate tolerance, immune reactivity, gut integrity, and goals. Ede explains her framework for customization and the impact of environmental toxins on food sensitivities.
- •Personalization is not about different cellular requirements; it’s about different tolerances, damage levels, and contexts.
- •First personalization layer: metabolic status—how insulin‑resistant someone is determines how low‑carb or ketogenic they may need to go.
- •Second layer: immune and gut integrity; environmental exposures (plastics, pesticides, antibiotics, food additives, ultra‑processed foods) erode barriers and raise food sensitivities.
- •Ede provides food lists in her book to help people systematically eliminate the most likely culprits instead of random trial‑and‑error.
- •Assessing where you are on the insulin resistance spectrum gives leverage over future physical and mental health risks.
- 57:20 – 1:11:40
Ketogenic Diet 101: History, Definition, and Brain Mechanisms
Ede defines what a ketogenic diet actually is, dispelling the notion that it is merely a fad weight‑loss regime. She recounts its origin as a fasting‑mimicking therapy for epilepsy and explains how ketosis affects inflammation, oxidative stress, neurotransmitters, and brain energy reliability.
- •A ketogenic diet was first designed in 1921 to control seizures in children by mimicking fasting without starvation.
- •It remains highly effective for epilepsy: >50% of patients get >50% seizure reduction; 10–20% become seizure‑free.
- •Mechanisms: reduces inflammation, oxidative stress, and insulin resistance; improves balance of neurotransmitters like glutamate, GABA, serotonin, dopamine, norepinephrine.
- •Fundamental idea: many mental and physical diseases are different expressions of the same underlying metabolic malfunction; the specific disease depends on individual vulnerability.
- 1:11:40 – 1:22:20
The Toulouse Study: Keto for Refractory Bipolar, Depression, Schizophrenia
Ede details the retrospective inpatient study by Dr. Albert Danan in Toulouse. Treatment‑resistant adults with severe mood and psychotic disorders tried a mildly ketogenic whole‑foods diet under close supervision, producing results that dramatically exceed typical psychiatric outcomes.
- •31 adults with chronic, treatment‑resistant bipolar disorder, major depression, or schizophrenia (ill on average 10+ years, many up to 30).
- •All were on ~5 psych meds each and had poor metabolic health (obesity, hypertension, high blood sugar, etc.).
- •28 remained on the keto diet for ≥2 weeks; all improved, 43% reached clinical remission, 64% reduced psychiatric meds, and all improved metabolic markers.
- •Hospitalization is both a confounder (environment change) and a strength (tight dietary and medical oversight).
- •The design can’t fully separate keto effects from other changes, but similar results are not seen with standard hospital diets and care.
- 1:22:20 – 1:31:00
Is It Keto, or Just ‘Healthier Food’ and Fewer Calories?
Steven pushes on whether the benefits might simply come from eating less junk or fewer calories, not ketosis. Ede explains insulin as the key regulator, alternative ways to get into ketosis (fasting, calorie restriction, exercise), and why keto is uniquely sustainable for long‑term ketone production.
- •Ketosis is fundamentally about lowering insulin enough to enable robust fat burning; carb quantity, protein, and energy intake all matter.
- •You can reach ketosis via fasting, heavy exercise, or very low calorie diets, but these methods are difficult or unsafe to sustain indefinitely.
- •A well‑formulated keto diet is the only practically sustainable way to remain in nutritional ketosis long‑term.
- •She acknowledges that cleaner, whole‑food, non‑keto diets would likely also improve outcomes compared to a standard Western diet; newer trials are needed to isolate ketone-specific effects.
- 1:31:00 – 1:52:40
Adherence, ‘Keto Flu’, and Why Keto May Still Be Easier
The conversation addresses the real‑world difficulty of sticking to keto in a high‑carb world. Ede contrasts early adaptation discomfort with long‑term appetite stability and provides practical strategies—such as slow transitions and electrolytes—to reduce the ‘keto flu’ that deters many people.
- •Biggest challenges: social environment, food availability, sugar addiction, and life logistics (travel, stress).
- •Ede claims that once adapted, keto is the easiest diet she has ever stuck to because of stabilized appetite and mood.
- •‘Keto flu’—headaches, fatigue, feeling worse before better—is mainly due to electrolyte shifts and abrupt metabolic switching.
- •Mitigation: supplement sodium/potassium/magnesium, taper carbs gradually over 1–2 weeks, and use a moderate‑carb ‘bridge’ phase.
- •Many people can sense ketosis by the ability to skip meals effortlessly and reduced food preoccupation, even before measuring ketones.
- 1:52:40 – 2:12:00
What Counts as ‘Keto Food’? Insulin, Not a Fixed List
Steven asks which foods are ‘allowed’ on keto and whether ketosis is binary. Ede reframes keto as a metabolic state determined chiefly by insulin levels and explains how blood ketone meters quantify ketosis. She notes that nearly any food can fit if you understand its insulin effect and portion context.
- •Keto is not inherently ‘meat and dairy’; you can be in ketosis with vegan, vegetarian, omnivore, or carnivore diets if insulin stays low.
- •Insulin responds to refined and whole carbohydrates, protein (especially processed forms), and minimally to fat.
- •Nutritional ketosis is commonly defined as β‑hydroxybutyrate ≥ 0.5 mmol/L in blood.
- •To reach that threshold, three things must happen: lower glucose, lower insulin, and deplete liver glycogen enough to trigger fat burning.
- •Ketosis activates repair, recycling, and maintenance pathways that are relatively dormant in constant high‑insulin states; Ede believes everyone benefits from spending at least intermittent time in ketosis.
- 2:12:00 – 2:23:00
Intermittent Ketosis, Ancestral Patterns, and the Mediterranean Question
Ede speculates that ancestral eating patterns likely allowed insulin to fall overnight, putting people into mild ketosis regularly, even without deliberate carbohydrate restriction. She differentiates between modern high‑carb, high‑snacking habits and whole‑food omnivorous diets where overnight healing periods may suffice for metabolically healthy individuals.
- •Historically, people ate fewer refined carbs, less often, and relied on seasonal whole‑food carbs; this likely led to nightly or frequent mild ketosis in the young and healthy.
- •Modern adults often require multiple days of fasting to reach ketosis due to chronic insulin resistance.
- •Children on standard diets sometimes wake up in mild ketosis, showing greater metabolic flexibility.
- •Metabolically healthy, active people might maintain brain health without strict keto by focusing on whole‑food carbs, meal timing, and overnight insulin dips.
- •The precise role of Mediterranean‑style diets in inducing clinically relevant ketosis remains to be clearly defined in controlled studies.
- 2:23:00 – 2:45:00
Diet and ADHD: Old Few‑Foods Trials and New Keto Studies
The discussion pivots to the surge in ADHD diagnoses and whether diet plays a causal role. Ede cites older European ‘few‑foods’ elimination trials in children and outlines forthcoming randomized trials of keto for adult ADHD and depression, while acknowledging the complexity of cause‑and‑effect and individual differences.
- •Few‑foods diets (chicken, lamb, limited fruits/vegetables, no common allergens) produced 62–82% response rates and ~70% apparent remission in some ADHD studies within weeks.
- •Despite this, major organizations (AAP, NICE) do not recommend dietary modification as standard ADHD treatment, citing ‘insufficient evidence’.
- •Ede argues that these low‑risk interventions warrant more use given the side‑effect and cost profile of stimulant meds.
- •Upcoming trials at Oxford and University of Michigan will test ketogenic diets for adults with ADHD, some with comorbid depression, tracking daily ketones and symptoms.
- •Epidemiologic links: children with obesity and adults with type 2 diabetes have roughly doubled ADHD rates, consistent with metabolic involvement, though causality is complex.
- 2:45:00 – 2:59:00
Medication, Function, and Lifestyle: Nuanced Treatment Decisions for ADHD
Steven shares his own ADHD diagnosis and decision to forgo medication, contrasted with dramatic benefits others report from stimulants. Ede draws on her specialist ADHD practice to acknowledge how life‑changing meds can be, while arguing that diet and lifestyle changes may prevent or reduce severity for many.
- •Stimulants are among psychiatry’s most effective medications and can be life‑changing, especially in severe ADHD.
- •ADHD carries serious risks: suicidality, substance use, accidents, depression, anxiety, and doubled divorce rates.
- •Severity spectrum matters—some can compensate via lifestyle design, others cannot function without medication.
- •Ede promotes a ‘risk‑benefit’ approach: consider meds, diet, exercise, and environment together rather than medication‑only or diet‑only dogma.
- •Keto may help a subset but is not proposed as a universal replacement for medication.
- 2:59:00 – 3:10:40
Case Study: Bipolar Suicidality Modulated by Ketosis
Ede recounts a bipolar II patient whose suicidal ideation was tightly coupled to his metabolic state. Each time he entered ketosis, his urge to die during marital conflicts disappeared, despite no change in external stressors, suggesting ketosis altered his emotional reactivity and coping capacity.
- •Patient with bipolar II had intense suicidal ideation triggered by marital arguments.
- •On a ketogenic diet, suicidal thoughts vanished; off keto, they rapidly returned—even though the marriage dynamics were unchanged.
- •Daily ketone tracking showed a close relationship between metabolic state and symptom intensity.
- •Patients often describe a ‘buffer’ or mental space in ketosis that allows more flexible, less reflexive responses to stress.
- •This pattern supports a direct biological role of metabolism in mood regulation beyond psychosocial factors alone.
- 3:10:40 – 3:24:00
Food Addiction, Insulin, and the Stress–Eating Feedback Loop
The conversation broadens to binge eating and food addiction. Ede explains that ultra‑processed carbs and sugar drive sharp glucose/insulin swings that in turn destabilize stress and appetite hormones, creating a self‑reinforcing cycle of craving and overeating that is engineered by food manufacturers.
- •Insulin is a ‘master metabolic hormone’ controlling not just blood sugar but appetite, satiety, stress hormones, reproductive hormones, and blood pressure.
- •Refined carbs cause glucose spikes that lead, hours later, to surges in adrenaline and cortisol, which feel like anxiety or irritability.
- •Example study: teenage boys who drank sugar‑sweetened soda had quadrupled adrenaline 4–5 hours later versus sugar‑free controls.
- •Ultra‑processed foods are deliberately engineered to be irresistible and unsatisfying, overriding natural satiety signals.
- •Removing refined carbs and processed foods for a few days can dramatically reduce cravings, giving people back a sense of control.
- 3:24:00 – 3:38:00
Case Study: Carl’s Lifelong Depression and Anxiety on Carnivore
Ede tells the story of Carl, a mid‑60s man with lifelong depression, anxiety, and exercise‑managed symptoms who deteriorated in his 60s. After failed medication and developing cannabis dependence, he tried a strict carnivore diet and experienced complete remission of his psychiatric symptoms within six weeks.
- •Carl had decades of depression/anxiety; medication improved depression but induced mania, leading to cannabis addiction.
- •He then used extreme exercise (cycling and walking up to 25 miles) as ‘medicine’ until symptoms overwhelmed even that.
- •On a dairy‑free carnivore diet (3–4 lbs of fatty pork/beef daily) with consistent mild ketosis, his anxiety attacks abated by week 3 and all depression/anxiety scores were zero by week 6.
- •He later reintroduced some carbs (potatoes, plain yogurt) to regain lost weight and adjust for exercise, maintaining remission.
- •Key lesson: understanding principles lets individuals tweak diets while preserving metabolic and mental benefits.
- 3:38:00 – 4:02:00
Carnivore, Nutrient Adequacy, Fiber, and Long‑Term Unknowns
Steven raises common objections to carnivore diets: nutrient deficiencies and lack of fiber. Ede argues that meat, seafood, and poultry together contain all essential nutrients, whereas no plant alone does; challenges the assumed necessity of fiber; and stresses the absence of long‑term data for any diet, urging open‑minded but cautious experimentation.
- •Ede maintains that meat/seafood/poultry provide all essential nutrients; eggs and dairy have some gaps if used alone.
- •Fiber is not an essential nutrient and is, by definition, indigestible by humans; its main benefits are contextual (blunting glucose spikes in high‑carb diets).
- •Claims that fiber ‘sweeps toxins’ lack direct empirical support; the gut self‑cleans via epithelial turnover and motility.
- •Butyrate for colon cells can be produced via microbial fermentation of fiber or via ketone metabolism on low‑carb diets.
- •There are no 20‑year randomized trials of any dietary pattern (Mediterranean, vegan, carnivore, keto); long‑term fears about keto should be balanced with clear, short‑ and medium‑term metabolic and mental health improvements.
- 4:02:00 – 4:16:00
Weight Loss, Insulin, and Why Ketones Matter More Than Calories
Many people use keto for body composition. Ede explains that fat loss fundamentally depends on lowering insulin, not just cutting calories, and that being in measurable ketosis is strong evidence that the body is actively burning fat, something that often doesn’t happen on conventional ‘healthy’ diets.
- •You cannot burn stored fat if insulin is chronically elevated; lowering insulin unlocks fat loss.
- •Ketones are a ‘mirror image’ of insulin: high ketones generally mean low insulin and active fat burning.
- •Stable glucose readings can mask high insulin; continuous glucose monitors cannot show insulin directly.
- •Her 91‑year‑old mother lost 50 lbs only when she achieved consistent daily ketosis, despite previously good glucose profiles.
- •Home ketone meters and CGMs are increasingly accessible tools that can guide individuals in fine‑tuning diets for both weight and mental health.
- 4:16:00 – 4:39:00
Implementation: Measurement, Psychology, and Multidisciplinary Support
Steven mentions his annual keto habit and lack of measurement. Ede underscores the value of tracking ketones to ensure true ketosis, describes how she uses long initial sessions to understand patients’ lives, and argues that effective keto interventions in mental health usually require a team approach including nutrition, medical, and psychological support.
- •Ketone meters help distinguish ‘low‑carb’ from true metabolic ketosis and guide individual carb/protein thresholds.
- •Most of Ede’s clinical work is not explaining science but helping patients navigate emotional ties to food, social pressures, and setbacks.
- •Initial evaluations often take 90–120 minutes over multiple sessions before any diet prescription is made.
- •Ideal care team: keto‑knowledgeable dietitian, prescribing clinician (for medication and physical monitoring), and therapist/coach for motivation and behavior change.
- •Around week 3, many patients experience a distinct shift as their cells adapt, with notable improvements in mental clarity and emotional stability.
- 4:39:00 – 4:54:00
Keto and Anxiety: Evidence and Emerging Trials
In response to a direct question about anxiety, Ede reiterates that reduced anxiety and enhanced mental clarity are among the most consistent benefits seen across her practice and the emerging literature. Steven notes recent systematic reviews and a Stanford pilot in serious mental illness, underlining that randomized trials are still needed.
- •Ede observes that most people experience markedly reduced anxiety within 3 days to 3 weeks of starting keto.
- •Mechanisms include stabilizing cortisol and adrenaline by removing glucose/insulin spikes, plus anti‑inflammatory and antioxidant effects.
- •A 2023 systematic review found promising signals for low‑carb/keto in mood and anxiety disorders but called for more RCTs.
- •A 2024 Stanford pilot in schizophrenia/bipolar reported improved energy, sleep, mood, and quality of life on keto.
- •Ede emphasizes keto as a powerful, but not yet fully validated, tool in the broader mental health toolkit.
- 4:54:00
Closing Reflections: Relationships, Regret, and Who the Book Is For
The episode ends with a personal question about avoiding regret at life’s end. Ede prioritizes cultivating a healthy, meaningful relationship over professional achievements, then returns to her mission: offering hope to people with mental health issues who feel they have tried everything, by equipping them with clear, practical nutritional science.
- •Ede’s personal answer to minimizing deathbed regret: focus on building at least one truly good, healthy relationship.
- •She is grateful to have written her book, but values personal relationships even more highly.
- •She positions the book for anyone with mental health concerns—especially those who feel out of options—who are willing to try one more evidence‑informed intervention.
- •The book is written for laypeople, translating metabolic psychiatry into accessible language and actionable strategies.
- •She encourages a ‘nutritionally pro‑choice’ stance: optimize the diet you can actually live with, using the principles of nourish, protect, energize.
