Peter Attia, a renowned physician and researcher, shares his 12+ year DEXA scan results, revealing the changes in his body composition, lean muscle mass, visceral adipose tissue, and more. He discusses how different dietary approaches, including ketosis, fasting, and high protein, and training protocols impacted his body composition and blood biomarkers. He also outlines his planned approach moving forward based on his most recent DEXA scan.

👨‍🔬 **DEXA scans and body composition tracking:** Peter discusses the importance of tracking data over time to identify trends in body composition. He shares his DEXA scan results from the past 12 years, highlighting the impact of various dietary and exercise interventions on his body composition.

📈 **Dietary and training protocols:** Peter delves into the effects of different dietary approaches, such as ketogenic diet, time-restricted feeding, and prolonged fasting, on his body composition and blood biomarkers. He also explores the impact of different training protocols, including endurance training, strength training, and blood flow restriction training, on his lean muscle mass and overall fitness.

🧬 **Metabolic health and blood biomarkers:** Peter emphasizes the significance of monitoring blood biomarkers, such as glucose, insulin, and cholesterol, to assess metabolic health and make informed decisions about dietary and exercise interventions.

🎯 **Future approach:** Based on his most recent DEXA scan, Peter outlines his planned approach for optimizing his health and body composition moving forward. He discusses his goals, strategies, and the lessons learned from his past experiences with different dietary and training methods.

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.
