Heart HealthPeter Attia Tackles Heart Disease, Dementia, NAD Skepticism and Strength Training Efficiency
In AMA #84, Peter Attia covers a broad range of practical longevity topics. He explains why family health history often outperforms genetic testing for assessing disease risk, and why cardiovascular disease remains undertreated despite available tools. He addresses whether someone can be overweight yet metabolically healthy, arguing fat distribution matters enormously. For time-pressed individuals, he outlines a minimum effective dose for strength training centered on intensity over volume. On dementia prevention, he prioritizes exercise, sleep quality, and cardiometabolic optimization. He expresses continued skepticism toward NAD-boosting supplements, specifying what evidence would shift his view. Finally, he clarifies when hydration and electrolyte supplementation genuinely matters versus when it is unnecessary. Throughout, Attia emphasizes applying evidence to individual risk tolerance rather than following one-size-fits-all guidelines.
