In this episode, Brent is joined by endocrinologist and longtime FDA leader Dr. G. Alexander Fleming to break down one of the most consequential diseases of modern life: type 2 diabetes. Dr. Fleming explains the real difference between type 1 and type 2, why insulin resistance is the root problem, and how biomarkers like fasting glucose, A1C, and fasting insulin work together to reveal your true metabolic health. He also discusses the promises and pitfalls of blockbuster medications like metformin and semaglutide, the public-health failures that helped fuel today's metabolic crisis, and why strength training may be one of the most important longevity tools we have. Hope you enjoy.
