The diets of tech execs: From Mark Zuckerberg’s ‘kill what you eat’ phase to Tim Cook’s love of Diet Mountain Dew

“I’m not sure how I’d survive without English Breakfast tea,” he told the Daily Mail in 2016.

Branson starts his day with fruit salad and muesli for breakfast. Occasionally, the billionaire will eat kipper, a herring-like fish, instead.

Earlier this year, Bezos’ fiancée, Lauren Sanchez, said that Bezos makes pancakes every Sunday morning.

“He gets the Betty Crocker cookbook out every time, and I’m like, ‘OK, you’re the smartest man in the world; why don’t you have this memorized yet?'” Sanchez told The Wall Street Journal.

The former news anchor told the Journal that Bezos is also “extremely dedicated to his workouts” with his personal trainer Wes Okerson.

The cookies are high in protein and fiber, and low in carbs, according to the company’s website.

Cuban invested in the company in 2012 after its cofounder sent him a sample box of the cookies with a letter asking him to invest $50,000 in the company for a 25% stake, CNBC reported.

“I don’t just eat them, I live on them,” Cuban says on his company website. “It is not an exaggeration to say there are days when I have had them for breakfast, lunch, and dinner.”

His favorite type of cookie is the Healthy Oatmeal Bite, according to the company.

“All those cans also add up to something like 35 pounds of aluminum a year,” Gates wrote in 2014.

Earlier this year, Michelin star chef Jordi Cruz said that Gates once reserved his entire restaurant for two days and only ordered a Diet Coke.

The Apple cofounder would sometimes eat only one or two foods at a time, for weeks, according to Walter Isaacson’s biography.

At one point, his diet was strictly carrots and apples. At another time, he was a “fruitarian” and would only eat fruits, vegetables, nuts, seeds, and grains, the book said.

Jobs told Isaacson he “swore off meat” when he was a freshman at Reed College, and he later gave up grains and milk.

“If there was a way that I could not eat so I could work more, I would not eat,” Musk said in Ashlee Vance’s biography “Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future.”

Musk used to skip breakfast — or eat a Mars bar or donut to start his day.

“I’m trying to cut down on sweet stuff, and I should have an omelet and coffee,” Musk said in 2017, according to Entrepreneur.

But he hasn’t appeared to curb the habit much. The billionaire said on X earlier this year that he eats a donut every morning. 

“I’d rather eat tasty food and live a shorter life,” Musk told Joe Rogan in 2020.

Musk posted a photo on X in 2022 of what he said at the time was his bedside table. The picture included four cans of caffeine-free Diet Coke.

Musk has expressed his love for the beverage several times over the years. 

In 2007, Inc. said in a profile of Musk that he was drinking eight cans a day at one point.

“I got so freaking jacked that I seriously started to feel like I was losing my peripheral vision,” Musk said, though he added that the electric-car maker has since begun offering caffeine-free Diet Coke at its offices.

In 2022, he wrote on X that he doesn’t care if Diet Coke “lowers my life expectancy.”

He once hosted Twitter cofounder Jack Dorsey and treated him to a goat he had killed, Dorsey told Rolling Stone. Dorsey said he remembered that the goat was served cold, so he stuck to salad for dinner.

In 2019, Dorsey said he only eats one meal a day — dinner — during the work week, then fasts the entire weekend, following a diet trend popular in Silicon Valley at the time called “intermittent fasting.”

The Twitter cofounder said it helps him focus.

By 2020, though, Dorsey said he was eating seven meals a week — just dinner.

“The first time I did it, like day three, I felt like I was hallucinating,” Dorsey said.

“It was a weird state to be in. But as I did it the next two times, it just became so apparent to me how much of our days are centered around meals and how — the experience I had was when I was fasting for much longer, how time really slowed down,” he said on a 2019 episode of the podcast “Ben Greenfield Life.”

In the post, he also noted that he takes methyl B-12, Omega-3, Iron, and Vitamin D-3 as supplements.

Recently, Altman said he also takes the diabetes drug metformin, which has become popular with biohackers as a way to slow aging.

While he usually consumes his first can with “potato stix” he sometimes switches it up with ice cream, Fortune said.

Buffet has jokingly said he eats “like a six-year-old” because actuarial tables say six-year-olds have the lowest death rate, Fortune noted. 

Bill Gates, a friend of Buffet’s, has observed that his fellow billionaire largely has a diet of McDonald’s hamburgers and Oreos, Fortune noted.
