Attia's case rests on reframing medicine around preventing the four chronic diseases that actually kill most people rather than reacting once they're diagnosed, and pairing that with fairly aggressive personal targets, LDL cholesterol far below conventional guidelines, extensive testing, and a heavy emphasis on structured exercise for what he calls the "Centenarian Decathlon." The most substantive criticism has been about who can actually use this advice: DEXA scans, continuous glucose monitors, and personal trainers assume a level of time and money most readers don't have, and the mental health chapter is noticeably thinner than the physiology-heavy chapters around it. Even critics who disagree with specific numbers, particularly the cholesterol targets, generally credit the underlying science as more rigorous than the typical longevity book.
