In this “Ask Me Anything” (AMA) episode, Peter reviews the last 12+ years of his DEXA scan results revealing the changes to his body composition, lean muscle mass, visceral adipose tissue, and more. He explains how his body composition and blood biomarkers were impacted by the various dietary approaches (ketosis, fasting, high protein, etc.) and training protocols (primarily endurance, primarily strength training, etc.) he has undertaken over the years. Furthermore, Peter explains his planned approach moving forward following his most recent DEXA scan in late 2022.
