We've traced the metabolic roots of cancer, kidney disease and Alzheimer's on this show. Keep going down that rabbit hole, and you arrive somewhere most people have never heard of: metabolic
psychiatry.
Dr Bret Scher spent over twenty years as a cardiologist before the revolving door of patients who weren't getting better sent him looking for what conventional medicine was missing. He now leads Metabolic Mind at the Baszucki Group, funding and connecting the researchers building the evidence base for ketogenic therapy in serious mental illness.
He and Ben get into where this field actually came from: epilepsy, then a string of accidental discoveries where people went keto for weight loss and watched decades of psychiatric symptoms lift. They cover what ketosis does to GABA and glutamate, why depressed brains show reduced glucose uptake but can still burn ketones, the \"brain energy mismatch\" theory, what GLP-1s reveal about metabolic root causes, and the trials landing over the next few years. Dr Scher is careful throughout about where the evidence is strong and where it's still case reports and theory.
MILESTONE MOMENTS
⚡ 03:51 — A woman in her seventies with decades of psychosis went on a ketogenic diet to lose weight. Her schizophrenia symptoms disappeared. Nobody was treating her psychiatric illness.
⚡ ~04:50 — Researcher Dr Ian Campbell, who lives with bipolar depression: \"If I'm going to be depressed, I don't want to be fat and depressed.\" Then the depression lifted too.
⚡ 07:27 — The way in for sceptical doctors: people with serious mental illness die prematurely from metabolic disease. You'd want to treat that anyway.
⚡ 10:07 — \"If it was just serotonin, SSRIs would be phenomenal at putting depression into remission. And they're not. We have to be honest.\"
⚡ 12:46 — Imaging shows reduced glucose utilisation in major depression and serious mental illness. But those same brains can still use ketones.
⚡ 14:49 — Pregnancy, infection, autoimmune disease — any surge in energy demand can tip an already marginal system over the edge.
⚡ 20:52 — Why GLP-1s improve cardiovascular outcomes and PCOS symptoms: not the arteries, the underlying metabolic health. Two doors to the same house.
⚡ 22:46 — \"You think that patient who's had intractable epilepsy and is now seizure-free cares what the mechanism is?\"
⚡ 30:40 — Continuous ketone monitors just got approved. Checking once a day tells you almost nothing about how ketones track with mood.
⚡ 41:05 — What has surprised him most in twenty years of medicine, and it isn't the science.
