Elon Musk reportedly once drank 8 cans of Diet Coke and a ton of coffee every day

Elon Musk may make batteries for a living, but the billionaire entrepreneur once required a shocking amount of caffeine to stay energised.

At one point, the Tesla and SpaceX CEO was reportedly consuming eight cans of Diet Coke and several large coffees in a day to keep himself alert and on top of his gruelling work schedule, Inc. previously reported.

This was back when Musk was working 100 hours per week during the launch of his companies.

“I got so freaking jacked that I seriously started to feel like I was losing my peripheral vision,” Musk told Inc. He claims his office now has caffeine-free Diet Coke.

Sure, we’re all guilty of craving a coffee pick-me-up, but that is a ton of caffeine.

Most adults can safely consume 400 mg of caffeine each day. Diet Coke has 42 mg of caffeine in each can (more than any other type of Coca-Cola), which means he was consuming 336 mg in just soda drinks.

Adding coffee into the mix likely put him over than 400 mg max. A tall coffee from Starbucks has about 260 mg of caffeine per cup.

Musk isn’t alone in his unhealthy eating habits.

Warren Buffett, who is 86 years old, has a McDonald’s breakfast sandwich every day. On days when the market is down, Buffett claims he is more frugal and opts for the $US2.95 Sausage McMuffin with egg and cheese. On good days, he’ll order the bacon, egg, and cheese biscuit for $US3.17. Every morning, he tells his current wife, Astrid, to put the exact change in the center cup holder of his car.

When Buffett arrives at his desk at Berkshire Hathaway in Omaha, he sits down to eat his breakfast with a glass of Coke. He drinks five Cokes per day.
