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

  • Shannon argues the GLP-1 conversation in low-carb spaces can overlook a key group: people eating clean, very low carb, and still not reaching health or weight goals, especially after major life stressors, and who may benefit from GLP-1 support without being framed as lacking discipline.
  • She shares her own experience gaining 40 pounds during her mother’s hospice and after her death despite maintaining the same low-carb approach, then losing the weight after starting a GLP-1, describing it as needed assistance rather than a shortcut.
  • Her main side effect has been lower-leg and foot muscle spasms that improved with higher daily electrolyte intake, plus temporary periods of very low appetite after dose increases that resolved over time.
  • She emphasizes the importance of dose flexibility, preferring vials over prefilled autoinjectors so patients can start lower, increase more gradually, and avoid overly large jumps that can trigger nausea, inadequate intake, fatigue, sleep disruption, and electrolyte imbalance.
  • Shannon draws a parallel to addiction medicine, describing GLP-1s as potentially analogous to evidence-based medications that quiet “brain chatter,” reduce relapse drivers, and should be discussed without stigma, while still supporting lifestyle changes and whole-food nutrition rather than “just fewer Oreos.”

GLP-1 and Ketosis: Novel Mental Health Treatments

Can weight-loss drugs help the brain? In this Metabolic Mind episode, Dr. Bret Scher interviews Dr. Roger McIntyre—Professor of Psychiatry and Pharmacology at the University of Toronto—about GLP-1 receptor agonists (e.g., Wegovy, Ozempic) and ketogenic therapy in mood disorders. Dr. McIntyre explains why psychiatry’s spotlight is moving from simple neurotransmitter theories to brain energy and cellular metabolism, and how GLP-1s might aid mood both indirectly (better metabolic health) and directly (GLP-1 action in brain circuits). He draws parallels with nutritional ketosis, noting overlapping effects on inflammation, insulin signaling, mitochondria, and neural networks. While optimistic, he stresses staying within current GLP-1 indications and building high-quality clinical trials for both medications and keto before broad psychiatric adoption. The takeaway: a future of “brain-protective” care that integrates meds, diet, sleep, exercise, and psychotherapy—shifting treatment toward resilience and offering real hope for people with depression and bipolar disorder.

Could GLP1 medications help patients go keto?

In this wrap-up episode, Dr. Bret Scher compares GLP-1 medications such as Wegovy and Ozempic with ketogenic therapy for metabolic and mental health. Experts discuss benefits, risks, and why lifestyle interventions—especially ketogenic diets—should come first, with GLP-1s serving as short-term bridges to lasting wellness.

Psychiatrist Shares His Experience With GLP1 Weight Loss Drugs with Dr Rodrigo Mansuer

In this Metabolic Mind episode, Dr. Bret Scher interviews psychiatrist–scientist Dr. Rodrigo Mansur (University of Toronto) about GLP-1 receptor agonists like semaglutide (Ozempic/Wegovy) in psychiatry. Beyond weight loss, GLP-1s act on brain circuits tied to mood, motivation, and cognition—raising the possibility of direct antidepressant and pro-cognitive effects. Mansur shares early signals from pilot work and an ongoing placebo-controlled trial of oral semaglutide in depression, where interim monitoring shows improvement without emergent suicidality so far. He emphasizes caution and balance: prioritize lifestyle and medication optimization, consider metformin, and reserve GLP-1s for carefully selected patients with close safety monitoring. For clinicians and patients navigating medication-induced weight gain and treatment-resistant symptoms, this conversation lays out current evidence, open questions, and how to discuss risks and benefits in real-world care.

The Ultra-Processed Food Debate: Science, Bias, & Truth

In this Metabolic Mind Podcast episode, Dr. Bret Scher hosts Harvard endocrinologist Dr. David Ludwig and investigative journalist Gary Taubes for a lively debate on ultra-processed foods, nutrition research quality, and scientific bias. They unpack why “ultra-processed” can be a vague, catch-all category, critique how randomized trials and media headlines may overstate conclusions, and discuss methodological red flags like short crossover designs, energy density confounding, and uneven dropouts. The conversation explores confirmation bias in peer review and funding, why mechanism-based thinking matters (especially for refined carbohydrates), and what individuals can do now—experiment thoughtfully with diet changes to see what improves their health.
