The physician behind Outlive and Medicine 3.0 — his Four Horsemen framework and where inflammation fits into it.
This page describes Peter Attia's publicly known work in detail. It is not a personal endorsement of THE FAD, and none of this is medical advice.
Peter Attia is a physician trained in general surgery who shifted his focus to what he calls "Medicine 3.0" — proactively addressing the root causes of chronic disease decades before they become symptomatic, rather than only treating disease once it appears. His book Outlive and his long-running podcast lay out this framework in detail.
Attia organises much of his work around four categories of disease responsible for the majority of non-accidental deaths: cardiovascular disease, cancer, neurodegenerative disease, and type 2 diabetes/metabolic dysfunction. Chronic inflammation is a recurring thread he discusses across several of these — directly overlapping with our own pages on heart health, cancer risk, and blood sugar.
Of everything Attia discusses, exercise — particularly a combination of Zone 2 cardio and strength training focused on stability and grip strength — gets the most emphasis in his own stated framework, more than diet specifics. See our Zone 2 cardio deep dive and HRV page for the research he frequently references on this.
Unlike some figures on this page, Attia has generally avoided prescribing one specific named diet, instead emphasising protein adequacy, avoiding metabolic dysfunction (tracked via markers like fasting insulin and continuous glucose monitoring), and personalising food choices based on individual biomarker response — a more flexible stance than strict programs like keto or paleo that some other figures in this space advocate more strongly.
Attia is generally careful to distinguish strong, replicated evidence from his own extrapolation and personal practice, and often says so explicitly on his podcast — a good model for how to read any single figure's recommendations critically, including everything on this page.
