If you want to eat and drink like a billionaire, forget the filet mignon, oysters, caviar and truffles, never mind the champagne and fine wine: Just scarf down a boatload of snack foods and soda pop.

That’s what mega-wealthy investor Warren Buffett does. At 84, the Berkshire Hathaway CEO – renowned for both his frugality and his curiously lowbrow taste in food – says he drinks at least five 12-ounce servings of Coca-Cola, made by a company he owns a great deal of stock in, every single day.

“I’m one quarter Coca-Cola,” Warren Buffett told Fortune. “If I eat 2700 calories a day, a quarter of that is Coca-Cola.”

Three of those Cokes (regular or Cherry) he’ll consume during the day, two at night. Sometimes he’ll have one for breakfast first thing in the morning, occasionally enjoying it with a can of potato sticks – Utz brand, to be precise, a company he told Fortune he’s thinking of buying. He has also been known to greet the day with a big bowl of ice cream.

His sugar-, sodium- and fat-heavy diet may not be terribly healthy, but he maintains that it’s strategic. “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,” he told Fortune. “It’s the safest course I can take.”
