Psychiatrist Dr. Chris Palmer reveals how ketogenic diets and carbohydrate restriction can treat depression, anxiety, and even treatment-resistant psychotic disorders by optimizing mitochondrial function and brain metabolism. His research shows a 33-year-old man with schizoaffective disorder lost 160 pounds and became seizure-free after adopting a ketogenic diet, with hallucinations resolving within weeks—despite failing 17 psychiatric medications. Mitochondrial dysfunction underlies multiple mental health conditions; restoring mitochondrial health through ketogenic diets, calorie restriction, and fasting can improve neurotransmitter production, hormone regulation, and inflammation control.
