In this episode, I share my full DEXA scan results, including a visceral fat score of 0.38 pounds, which I’m determined to drop to “0.0 fricking zero” through sprinting—shown in research to preferentially burn visceral fat.

My body fat is 21 pounds (12.5%), and I break down the fat and lean mass distribution throughout my body, including minor asymmetries. I was advised to gain 2–3 pounds of muscle for longevity, though my sprinting and high jump goals favor staying lean. I discuss why chronic endurance training can increase visceral fat due to cortisol overproduction, while short, explosive workouts like sprints or strength training create a healthy stress response.

You’ll also learn why bone density suffers in cyclists and astronauts, what makes muscles a glucose sink, why Dr. Ron Sinha and Dr. Gabrielle Lyon emphasize maintaining muscle as the key to long-term health and metabolic flexibility, and I end the show with a plug for muscle-centric medicine—focusing on building and maintaining muscle as the key to longevity and leanness.
