Bret Scher, MD

Medical Director, Metabolic Mind and Baszucki Group

Bret is the host of the Metabolic Mind YouTube channel and podcast. He is a board-certified cardiologist, lipidologist, and leading expert in therapeutic uses of metabolic therapies, including ketogenic diets. Prior to joining Baszucki Group, Bret was the medical director at DietDoctor.com, an online platform promoting improving metabolic health through low-carb nutrition, where he was a content creator and medical reviewer. Earlier in his career, he worked as a cardiologist in San Diego. Bret has spent most of his 20-year career as a preventive cardiologist, helping people improve their metabolic health and preventing heart disease using low-carb nutrition and lifestyle interventions. His deep passion for educating the public about the benefits of metabolic therapies grew from his experience with the prevailing medical teaching, which frequently misrepresents nutrition science and undervalues metabolic health. Bret received an MD from The Ohio State University College of Medicine and a BS in Biology from Stanford University. He grew up in San Diego and began competing in triathlons at an early age, which helped fuel his love of health and fitness. He continues to enjoy spending time outdoors mountain biking, swimming, hiking, and playing baseball with his two boys.

Key Highlights

  • Cardiovascular disease is the leading cause of mortality among people with severe mental illness, contributing to a life expectancy that can be approximately 20 years shorter than their peers.
  • A large analysis of nearly 36,000 participants found that antipsychotic medications can negatively affect glucose regulation regardless of weight gain, treatment duration, diagnosis, age, or previous antipsychotic exposure.
  • The experts argue that psychiatrists should take a more active role in metabolic care—screening and monitoring glucose, insulin, lipids, blood pressure, and other cardiometabolic risk factors rather than assuming another clinician will address them.
  • Improving metabolic health may also improve psychiatric treatment outcomes, as obesity and insulin resistance are associated with poorer responses to treatments for depression, highlighting how closely metabolic and mental health interact.
  • Treatment doesn’t have to be either psychiatric or metabolic: exercise, dietary interventions, ketogenic therapy, medications such as metformin or GLP-1 drugs, and standard psychiatric care may all have roles in a more comprehensive approach.

The Healing Depression Project: A New Path Beyond “Treatment Resistant” Depression

The Metabolic Mind Podcast features Silvia Covelli and functional medicine psychiatrist Dr. Achina Stein discussing the Healing Depression Project, an immersive retreat designed to address root causes of chronic and treatment-resistant depression. They explore how functional medicine testing, therapeutic ketogenic nutrition (gluten- and dairy-free), sleep repair, morning light exposure, daily walking, meditation, and intensive psychodrama can work together to reduce symptoms. The conversation highlights why a one-size-fits-all, pill-only approach often falls short, shares early outcome data and follow-up insights, and offers practical priorities for people seeking sustainable depression recovery through metabolic and lifestyle strategies.

Is Ketosis Safe for Mental Health?

In this Metabolic Mind episode, Dr. Bret Scher explains why nutritional ketosis is a safe, natural metabolic state and not to be confused with life-threatening diabetic ketoacidosis. He breaks down how the body alternates between burning glucose and fat, how ketones fuel the brain, and why ketogenic therapies are emerging as powerful tools for improving mental health. This clear explanation helps viewers—and their clinicians—understand the science behind ketosis, its safety, and its potential benefits for conditions like bipolar disorder, depression, and schizophrenia.
