Biohacker Bryan Johnson ditches meat to 'live forever' but still hits 130g protein daily on a vegetarian diet. Here's his secret

Billionaire biohacker Bryan Johnson, known for his $2 million-a-year anti-aging project Project Blueprint, has shared how he meets his daily protein requirements on a vegetarian diet. Johnson, who has sold his payments company Braintree to PayPal for $800 million, revealed his eating strategy on X (formerly Twitter), offering insights into both his personal health philosophy and his futuristic thinking.

Two Reasons He Avoids Meat
In a recent tweet thread, Johnson explained, “I don’t eat meat for two reasons. First, scientific evidence paints a path to optimal health without it. Second, very soon, AI may be as powerful and dominant to us as we are to animals. It’s prudent to keep this in mind.”

His decision reflects not only a commitment to longevity but also a broader ethical and existential perspective shaped by the rapidly evolving role of artificial intelligence.

I consume 130g of protein daily from flax, pea, hemp, legumes (lentils, peas, beans), vegetables, collagen peptides, nuts and seeds.

Hitting Protein Goals Without Animal Products
Despite skipping meat, Johnson consumes 130 grams of protein daily, relying on plant-based and vegetarian-friendly sources. He detailed, “I consume 130g of protein daily from flax, pea, hemp, legumes (lentils, peas, beans), vegetables, collagen peptides, nuts and seeds.”

This combination allows him to fuel his intensive anti-aging regimen, which includes hyperbaric oxygen therapy, red light exposure, precise sleep tracking, and rigorous exercise, all part of his long-term mission to optimize human health.

From Anti-Aging to Anti-Extinction
Johnson’s vegetarian choices tie into a larger philosophy he calls the “Four Layers of Don’t Die,” where individual health, cultural investment, governance, and technological alignment converge. He argues that humanity must prioritize vitality and preservation — especially as AI systems grow increasingly powerful.

“Superintelligence is in the birth canal on planet Earth,” Johnson wrote in a recent post. “If control is limited, the only rational act is alignment. We align with life itself.” His plant-based diet is one small but symbolic part of this broader vision.

Johnson’s approach underscores the intersection of personal health and global ethics. Critics have questioned whether longevity science can truly defy biology, yet Johnson reframes the discussion, linking diet, lifestyle, and AI ethics into a singular vision: to ensure not just human survival, but civilization’s ability to teach life to future intelligence.
