Longevity expert Bryan Johnson reveals his 'Don't Die' diet, prison edition, for entrepreneur in jail. Netizens react: 'He'd be in prison for centuries'

Elizabeth Holmes, the former Theranos chief now serving an 11-year prison term for deceiving investors, has unexpectedly resumed her presence on X, the platform once known as Twitter. Beginning on September 2, she started posting again, surprising many who assumed incarceration would keep her silent.

A Request to a Longevity Expert

Just days later, on September 5, Holmes directly appealed to Bryan Johnson, a well-known biohacker and longevity enthusiast, asking him to devise a prison-friendly nutrition plan designed to extend lifespan. Johnson, who has become famous for his strict wellness experiments, responded by tailoring a detailed meal guide based on limited prison food choices.

The Suggested Meal Plan

Responding to the request, the longevity expert said this was what he'd eat in prison: Johnson’s plan offered a structure that combined balance with practicality. Breakfast included oats with almond milk, raisins, and a small portion of almonds. Lunch had two possible variations: one revolving around brown rice, dehydrated vegetables, tuna, and olive oil, and another featuring bean chili with an occasional addition of beef for iron. A protein bar and cashews were suggested as snacks, while dinner mirrored lunch with rice, vegetable flakes, and mackerel. The day concluded with peppermint tea. Johnson estimated the plan to provide around 1,800 calories, nearly 100 grams of protein, close to 200 grams of carbohydrates, and about 90 grams of healthy fats.

Viral Reactions on Social Media

The post quickly gained attention across the platform. Holmes responded with a tongue-in-cheek thank-you, wishing Johnson eternal life. Other users chimed in humorously, suggesting he create affordable versions of such diet plans for underprivileged urban communities, while one quipped that Johnson himself should avoid prison since his anti-ageing methods might keep him confined indefinitely.

Johnson’s Larger Mission

Beyond this viral exchange, Bryan Johnson remains deeply invested in reversing biological ageing. He reportedly spends nearly $2 million annually on advanced medical testing, supplements, and a rigid routine of exercise, sleep, and diet. Having sold his payment technology firm to eBay in his 30s, Johnson now dedicates his resources and time exclusively to exploring whether science can meaningfully delay or even undo the effects of growing older.
