Mark Hyman: meet the doctor who says he can make us live to 120

Hyman is tall and handsome, a very clever hunk, young Michael Douglas meets Christian Bale. He is one of those doctors whose Instagram follower count (2.8 million) dwarfs Edward Enninful’s (1.6 million) and whose podcast guests include Gwyneth Paltrow. He speaks quickly and confidently without raising his voice; monotonous and instructive, like an ASMR with perks. “It’s important to get people to follow a diet that’s going to activate what I call the longevity switches,” he says, using the kinds of words that make the British grimace. “I focus on treating the body as a system,” he says, and on “the fundamental pathways that activate our healing, repair, and regeneration.” “I was a yoga teacher before I became a doctor,” he adds later.
