Bryan Johnson's Two Primary Reasons for Not Eating Meat

Biohacker Bryan Johnson has publicly stated two main reasons for his meat-free diet, a key component of his intensive Project Blueprint aimed at reversing aging.

Reason 1: The Health and Longevity Argument

Johnson's first reason is based on his team's analysis of extensive scientific data, which he believes indicates that a plant-based diet offers the optimal path toward health and longevity. The Blueprint protocol is an evidence-based system, and every component, including his diet, is meticulously tracked and adjusted based on biomarkers.

• Data-driven diet: Johnson's vegan-by-choice diet consists of precise, nutrient-dense meals like the 'Super Veggie' and 'Nutty Pudding'. His team continually refines the diet based on blood tests, MRI scans, and other diagnostic data, aiming for peak physiological function.
• Scientific consensus: While not all longevity researchers agree on the optimal diet, numerous studies link high plant-based food intake to reduced risks of heart disease, type 2 diabetes, and other age-related conditions. Johnson aligns his intake of whole foods, fiber, and polyphenols with this research.
• High protein intake: Despite being plant-based, Johnson consumes around 130 grams of protein daily from sources like legumes, seeds, and protein powders, ensuring he meets his nutritional needs without animal products. He acknowledges that some things cannot be acquired from diet alone, necessitating his extensive supplement stack, which includes non-vegan collagen peptides.

Reason 2: The Ethical and AI Alignment Argument

Johnson's second, more philosophical reason is rooted in his ethical concerns regarding the future of artificial intelligence.

• Compassion as a scaling law: Johnson posits that humans' treatment of animals today could set an ethical precedent for how future, more powerful AI might treat humanity. By modeling compassion toward less powerful beings, he hopes to instill this value in the developing superintelligence.
• A personal experience: This ethical view was cemented after a hunting experience where he emotionally broke down, realizing his responsibility in taking an elk's life. This moment was a significant turning point in his adoption of a strictly plant-based lifestyle.
• The bigger picture: His anti-meat stance connects to a larger philosophical framework he calls the "Four Layers of Don't Die," which links individual health to broader ethical and technological alignment. For Johnson, individual health choices are part of a grander mission to ensure humanity's long-term survival and prosperity alongside advanced AI.
