Bryan Johnson — known for being the biotech CEO spending millions on his experimental approach to reversing aging — follows a strict diet that involves eating a blended mush of steamed vegetables and lentils, according to a Time Magazine profile published Wednesday.
Johnson told Time's Charlotte Alter that he thought his strict health routine was "the most significant revolution in the history of Homo sapiens."
"I no longer have arousal from eating junk food," Johnson told Insider in a separate interview. "People think that a cheat day for me, like the reward would be eating pizza and donuts. It makes me nauseous to even think about," he said.
This blended vegetable mush forms only one part of his daily diet, according to Johnson's website, which also features images of his meals — though only before they're blended.
The rest of it includes eating over 100 supplement pills a day, a "nutty pudding" — a mix of macadamia nut milk, ground nuts, and fruits — and a third meal that varies between options like a roasted veggie lettuce wrap and chickpea curry over greens.
Johnson also defended his unusual approach to extending his lifespan — which he calls Project Blueprint — on-stage at the anti-aging conference RAADfest in September, saying that criticism of Project Blueprint stems from addiction to bad behavior.
He added that he thought society's addiction to bad behavior comes from being surrounded by fast food joints, sugary drinks, and the smartphone — which he described as "a basically heroin-like device."
"If you could actually measure the biochemical reactions between the two of us," said Johnson, referring to detractors of his diet, "I would argue I experience more exquisite joy from my food consumption than they do."
To be sure, scientists told Insider that Johnson's approach has unclear health benefits.
"If you expect to live significantly longer than, say, 115 — which is more or less the maximum lifespan of our species — then there is currently zero evidence this can be accomplished," Jan Vijg, a genetics professor at the Albert Einstein College of Medicine, told Insider in February.
Johnson did not immediately respond to a request for further comment, sent outside regular business hours.
