This interview features Natalie West, a 20-year clinical psychologist and psychotherapist who has spent 15 years treating mental health conditions through dietary intervention. Natalie shares how she was mentored early in her career by a specialist in psychiatric nutrition who insisted that gut health and food choices were inseparable from psychological wellbeing. Long before it became mainstream, her clinical approach already involved eliminating wheat, gluten, processed foods, and sugar for patients presenting with depression, anxiety, and high-end disorders like schizophrenia.
A significant portion of the conversation explores the gut-brain connection, including the fact that over 75% of the serotonin the body needs is produced in the gut. When the gut is inflamed by sugar and processed foods, neurotransmitter production breaks down entirely. Dr. Anthony Chaffee explains that ketones, not glucose, are the brain's primary fuel source, and that switching to a ketogenic or carnivore diet bypasses insulin resistance in the brain, effectively "turning the lights back on" for people who have suffered chronic depression or cognitive fog. Natalie also highlights work by psychiatrists like Dr. Chris Palmer and Dr. Georgia Ede, whose studies show ketogenic diets reducing or eliminating hallucinations and medication dependency in patients with severe schizophrenia.
Natalie recounts her own shift to a fully zero-carb carnivore diet after reintroducing sourdough bread during lockdown caused facial numbness and borderline Type 2 diabetes markers. Within two weeks of going carnivore, her energy surged, inflammation dropped, and her thinking sharpened. She now incorporates three structured adaptation phases into her clinical protocol, combining weekly psychological adjustments with dietary transition support. She also shares a client case where a man who had attempted suicide six weeks prior reported, after working with her, waking without depression or anxiety for the first time.
The conversation also challenges the idea that a vegan diet supplemented with synthetic nutrients is nutritionally equivalent to an animal-based diet. Natalie argues that if a diet requires heavy supplementation, it is by definition inadequate. Both speakers discuss how heme iron, complete amino acids, and high-quality fat from animal sources are essential for hormone production, neurotransmitter synthesis, and sustained mental health. Listeners dealing with treatment-resistant depression, anxiety, or more serious psychiatric diagnoses will find this episode particularly valuable as a guide to understanding the dietary roots of mental illness.
Key Takeaways
- Over 75% of the body's serotonin is produced in the gut, meaning that a diet high in sugar and processed foods directly degrades neurotransmitter production and contributes to depression and anxiety.
- Ketones are the brain's primary fuel source according to biochemistry textbooks, and switching to a ketogenic or carnivore diet bypasses brain insulin resistance, restoring mental clarity and energy where carbohydrate-driven metabolism fails.
- Eliminating wheat and gluten can have rapid neurological effects: Natalie developed facial numbness within 7 days of reintroducing sourdough bread, and blood tests revealed borderline Type 2 diabetes markers and a celiac marker she had not previously identified.
- Severe psychiatric conditions including schizophrenia have shown dramatic improvement on ketogenic diets. In one case cited by Dr. Chris Palmer, a patient's hallucinations disappeared within 4 weeks and he was fully off medication; in another, a woman in her 70s with schizophrenia diagnosed at age 17 was medication-free within 6 months.
- Higher LDL cholesterol supports brain function by enabling correct neurotransmitter production (including GABA, dopamine, serotonin, and norepinephrine), and is also essential for sex hormone synthesis, making cholesterol-lowering interventions potentially harmful to mental health.
- Eating every 3 hours to 'boost metabolism' is counterproductive because the resulting constant insulin elevation actively suppresses metabolic function. Shifting to carnivore or zero-carb eating eliminates chronic insulin spikes and restores natural hunger signals.
- Cravings during dietary transition are not commands to act on. Consuming high-salt electrolytes at craving peaks (typically around 4pm) can suppress cravings effectively, and cravings diminish substantially once the adaptation phase is complete.
- Supplementing a vegan diet with synthetic nutrients does not make it nutritionally equivalent to an animal-based diet because synthetic supplements lack the bioavailability of food-derived nutrients, and plant compounds like oxalates (in spinach and kale) actively block absorption of other nutrients.
