A 45-year-old tech exec who says he has reduced his biological age by 5 years says he finishes his last meal of the day by 11 a.m.

• Bryan Johnson spends up to $2 million a year on a rigorous program to reduce his biological age.

• The tech exec recently confirmed he eats his last meal of the day at 11 a.m.

• His typical "dinner" consists of meals like an orange and fennel salad or a stuffed sweet potato.

In order to dramatically reduce his biological age, 45-year-old tech entrepreneur Bryan Johnson abides by a rather unconventional eating schedule: He eats his last meal of the day at 11 a.m.

Johnson has an $2 million-a-year anti-aging program known as Project Blueprint. The program, Johnson and his doctors claim, has helped him restore his heart to that of a 37 year-old, tightened his skin to that of a 28-year-old, and brought his lung capacity back to that of an 18-year-old.

"My final meal of the day is at 11 am," he wrote in the comments of a post from a surprised Twitter user who had asked him to verify whether he really ate "dinner" at such an early hour on Tuesday. ""I eat between ~6-11am," he added.

Johnson, a centimillionaire according to Bloomberg, earned a bulk of his wealth as the founder of Braintree, a payments processing company that he sold to eBay for $800 million in cash in 2013. He later founded a biotech focused venture firm called OS Fund, and Kernel, a company that makes helmets to monitor brain activity.

Within a five-hour window, Johnson eats three meals, according to an overview of his diet available on Blueprint. That includes a "Green Giant" smoothie chock full of supplements like Spermidine, creatine, and collagen peptides, a "Super Veggie" salad, a "Nutty Pudding," and a third meal (i.e. dinner) of around 500 calories.

Some examples of the third meal listed on Blueprint include an orange fennel salad made with Cara Cara oranges, fresh mint, and goji berries. Or, a stuffed sweet potato filled with chickpeas, roasted grape tomatoes, and mashed avocado.

In addition to these meals, Johnson takes a host of supplements including zinc, turmeric, and lithium. All in all he takes in about 1977 calories a day and, according to Blueprint, spends about $44.91 a day on food and $11.24 a day on supplements. His "dinner" usually averages out to around $11 a day, based on Blueprint.

In an email to Insider, Johnson said he's been trialing different eating windows and times for two years. Between his Blueprint diet and the 6 a.m. to 11 a.m. eating window Johnson said that his resting heart rate is between "~46-50 bpm at bedtime" which he added was the strongest predictor of his sleep quality.

And while Johnson now seems pretty committed to his anti-aging regimen he's also admitted that he wasn't always this fastidious about eating to live longer.

In a 2020 post on Medium titled "I fired myself" Johnson wrote that he was regularly binging on carbs and sugar between 5 to 10 p.m. "Evening Bryan," as Johnson called his alter ego in the post, "overate and gained more than fifty pounds, fueling relentless shame, guilt and malaise."

Johnson wrote that this behavior had repercussions on his mood, sleep, and performance. "In short, Evening Bryan was making life miserable for all Bryans," he wrote.

"So, a year ago, I fired Evening Bryan from his shift, revoking his authority to make food consumption decisions." Since then only "Morning Bryan" is authorized to make decisions on when, what, and how much to eat, Johnson wrote.
