Depression, Ketones, and the Brain: What the Newest Science Reveals

In this part 2 of my interview with Dr. Bret Scher, double board-certified cardiologist, lipidologist, and Medical Director at the Metabolic Mind and Baszucki Group, we explore the revolutionary connection between metabolic health and mental health — and how ketogenic therapy may reshape psychiatry forever. We discuss the new Translational Psychiatry 2025 study showing that a ketogenic diet led to dramatic improvements in depression symptoms — with 100% of participants improving and an average 70% reduction in depression scores. We break down the study design, clinical implications, and what this means for the future of mental health treatment. From inflammation and neurotransmitters to insulin resistance and brain energy metabolism, we dive into the mechanisms explaining how ketones support brain health. Dr. Scher also shares how the Coalition for Metabolic Health aims to unite experts across cardiology, endocrinology, and psychiatry to address the global metabolic crisis. If you’ve ever wondered how diet affects the brain, or why the future of psychiatry may lie in metabolism, nutrition, and mitochondrial health, this conversation will expand your mind — and give you hope for a more holistic, science-based approach to mental health.
