Attia, a onetime researcher who earned an M.D. but never completed his surgical residency, is beloved by his fans for his measured, scientific approach to living one’s best life. On a recent podcast, he spends two hours examining Alzheimer’s disease in women. Other episodes delve into timely topics such as protein intake, fertility, chronic pain, and nicotine; his October discussion about the safety of Tylenol use during pregnancy offers an evidence-based counterpoint to the alarmist White House press conference on that issue. But he’s also been knocked for overhyping treatments with limited data behind them and for exploiting his eager fans (a course he offered on longevity cost $2,500, according to a 2023 Wall Street Journal article). Eric Topol, a high-profile cardiologist who directs the Scripps Research Translational Institute, called Attia a “huckster” earlier today.
