Peter Attia explores bone health across the lifespan, starting with how bone mineral density (BMD) works, how it’s measured (e.g., DEXA scans), and how it changes with age — especially between men and women due to hormonal influences like oestrogen. He explains the serious consequences of poor bone health, such as fractures and increased mortality, and discusses risk factors including age, sex, medications, and prolonged inactivity. He also covers preventive strategies: the role of exercise and mechanical loading in strengthening bones, nutrition and supplements, timing of BMD scanning, how children can build bone early in life, and how to mitigate bone loss during sedentary periods or weight loss.
