Why Tech CEO Bryan Johnson Eats His Last Meal of the Day Before Noon

The reverse age-er might finish dinner before you’re awake.


any intermittent fasters like actor Mark Wahlberg and longevity expert Andrew Huberman cook up the first meal of their day around noon, but by that time, tech CEO Bryan Johnson is already done with his daily food intake. In a recent tweet, the 45-year-old longevity chaser revealed  that he eats dinner at 11 a.m. 

In the comments, followers asked Johnson if dinner (which sometimes means “lunch” in the UK) was his third meal. He confirmed that “dinner” is “the final meal of [his] day.”

Frontloading his caloric intake into the first few hours of the day is just the latest method in Johnson’s Project Blueprint, a multi-million dollar attempt at reversing his biological age. Other tactics include injecting himself with blood from his 17-year-old son, swearing off solid food for green mystery mush, and downing 27 supplements a day. 

Since starting Project Blueprint in 2021, he told Bloomberg that he’s reversed the biological age of his heart to 37, his skin to 28, and his lungs to 18 years old. His ultimate goal: is to reverse the age of 70 of his organs to 18 with the help of 29-year-old self-proclaimed “rejuvenation doctor” Oliver Zolman.

Johnson says that he eats in a time restricted window between 6 a.m. and 11 a.m., following an  extreme intermittent fasting protocol. 

Intermittent fasting, or time restricted eating, may have longevity boosting benefits by promoting autophagy—the process in which your cells clear out old or damaged proteins—and weight loss (1). It may also boost brain and heart health, lower chronic disease risk (2), reduce inflammation (3), and aid in glucose regulation (4).

Other longevity experts who claim to have reversed their biological age, like David Sinclair and Mark Hyman, also employ intermittent fasting as part of their routine. 

I guess we’ll be on the lookout to see if Johnson goes full Benjamin Button and turns into a baby.
