Bryan Johnson, who sold Braintree for $800 million, treats his diet like software: each version is tested, measured, and refined based on clinical data and outcomes. His biological age is 0.64, meaning he ages only 7.6 months per calendar year. Every calorie must justify itself.
Years ago, I sold my company, Braintree Venmo, for $800 million. I've been spending those millions trying to reduce my speed of aging, and I just achieved a personal best, 0.64. That roughly means that for every 12 months that pass, I only age for 7.6 months. Now, an important part of this is my diet. My team and I have gone through a methodical process over the years where we've built my diet much like I built software at Braintree Venmo. When you build software, you build version one, and it moves to version two and version three. Every version get a little better because you remove the bad stuff and you add more good stuff. I've done the same thing with my diet. We've gone through all the scientific evidence. We've combed through all the best studies. We've identified what the clinically relevant dose is. We've put that into a program where every calorie has to fight for its life. I then ingest it for a while. We measure my body, and I become the most measured person in history. And we see, did it have the effect we thought it would have? And we repeat this again and again and again, version one to version two to version three.
