Peak Human - A Food Lies Film Podcast

Dr. Doug McGuff is an emergency physician, exercise researcher, and co-author of Body by Science. Known for his pioneering work in high-intensity resistance training, McGuff blends decades of medical practice with deep knowledge of physiology to reveal how short, focused workouts can yield extraordinary health benefits. He also runs training studios in South Carolina that specialize in safe, supervised strength training. In this episode of Peak Human, Brian Sanders and Dr. McGuff dive into why most people misunderstand exercise, the dangers of overtraining, and how nutrition and movement fit together for long-term health. They cover everything from the “12-minute workout” to the role of myokines, why VO₂ max is misunderstood, and how subsidies and processed foods hijacked the human diet. This conversation reframes what it truly means to build strength, resilience, and health for life.     Show Notes: 03:00 Dr. McGuff’s Background: Emergency Medicine & Strength Training 07:00 Adaptive Resistance Training
