Dr. Erin Bellamy, a clinical psychologist and pioneer in metabolic psychiatry, argues that ketogenic metabolic therapy can be a powerful, sustainable alternative to psychiatric medications for mental health conditions—especially those tied to food addiction. Drawing from her PhD research and clinical work at IKRT, she explains how nutritional ketosis, achieved through a low-carb, high-fat diet and strategic fasting, can reduce depression, anxiety, and binge-eating behaviors by stabilizing brain chemistry. Unlike medications that often worsen metabolic health, ketosis improves insulin sensitivity, reduces neuroinflammation, and creates a 'buffer' that helps individuals resist food triggers—similar to the effects of GLP-1 drugs but without muscle loss or long-term dependency. Bellamy emphasizes that the brain is fundamentally metabolic, and ignoring nutrition in mental health treatment is a critical oversight. She shares compelling clinical results from her 19-person study and outlines a vision for scaling this therapy globally via telehealth, especially for underserved populations. Her message is clear: fix the metabolism first, and mental health outcomes improve dramatically.
Nutritional ketosis (under 50g carbs/day) reduces depression and anxiety symptoms by regulating neurotransmitters like GABA and glutamate.
Ketogenic therapy creates a 'buffer' that helps people resist food triggers, even in high-risk environments like supermarkets.
GLP-1 drugs reduce appetite but cause muscle and bone loss; ketogenic diets preserve lean mass while offering similar food noise reduction.
Exogenous ketones can help during the transition into ketosis but should not replace endogenous ketone production.
Metabolic health is foundational to mental health—fixing diet and metabolism may be more effective than medication alone for many.

Introduction to Metabolic Psychiatry and Dr. Bellamy's Journey
Dr. Vera Tarman introduces the episode and guest Dr. Erin Bellamy, a clinical psychologist and CEO of IKRT, who specializes in ketogenic metabolic therapy for mental health and food addiction.
From Eating Disorders to Metabolic Psychiatry
Bellamy shares how her academic focus on eating disorders and emotional regulation led her to explore the biological underpinnings of mental health, culminating in her discovery of the 1965 study on ketogenic diets and schizophrenia.
Defining Ketogenic Metabolic Therapy
Bellamy clarifies the difference between metabolic psychiatry (the umbrella field) and ketogenic therapy (a key intervention), defining therapeutic carbohydrate restriction (20–50g/day) and distinguishing it from 'dirty keto' or fad diets.
The Brain-Body Connection: Metabolic Roots of Mental Illness
Bellamy argues that conditions like schizophrenia, bipolar disorder, and depression share metabolic roots—insulin resistance, mitochondrial dysfunction—and may be manifestations of 'type 3 diabetes'.
Ketogenic Therapy vs. Psychiatric Medications
Bellamy critiques antipsychotics that worsen metabolic health, advocating for ketogenic therapy as a first-line or complementary intervention to mitigate side effects and improve overall outcomes.
“not what you think and it's more about the bio than the psycho and the social, but together it's all three.”
“gave me once was it's like there is a pane of glass. between me and that. And there's just, I'm not interested. I can walk down past it without a problem.”
“We know that ketogenic therapy can work for so many people, but how do we get it to the people that either can't get out of bed because they're so depressed, but you get to reach them in their own home through the internet?”
