In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber sit down with Tony Orlando, founder of Dexa Plus and DexaScan.com, to unpack why DEXA scans are becoming one of the top longevity markers. They explore how DEXA goes far beyond a simple "body fat test," revealing bone density, muscle distribution, and visceral fat levels that directly impact long-term health, performance, and fracture risk. Tony explains why waiting until insurance finally covers a scan at age 65 or 70 is

Dr. Marc Humbert and Dr. Cameron Garber break down how your body produces ATP through the ATP-PC, glycolytic, and oxidative systems, why "power" (max rate) and "capacity" (how long) are different, and how CardioCoach metabolic testing (VO₂, VCO₂, fuel use) turns those ideas into precise workouts. We dig into thresholds, "fat max,"
