I ate like Warren Buffett for a week - and it was miserable

Warren Buffett is one of the most successful investors in history.

He also has a really weird diet.

Buffett's diet of sugary soda, junk food, and limited vegetables has reached legendary status.

The Berkshire Hathaway CEO drinks around five cans of Coca Cola products a day, munches constantly on See's Candies, and uses so much salt former Wells Fargo CEO John Stumpf said it was like a "snowstorm."

Business Insider has tried various people's diets - from Elon Musk to Tom Brady - so I decided to take on Buffett's strange food tastes for a work week and see what it was like.

There were some basic ground rules - three meals a day, no alcohol, and avoiding vegetables.

Overall, I just tried to maintain the general attitude that the man himself defines his diet.

"I checked the actuarial tables, and the lowest death rate is among six-year-olds. So I decided to eat like a six-year-old," Buffett told Fortune. "It's the safest course I can take."
