Yes, but Buffett’s diet has been famously bad and well documented in the media. Cookies and ice cream for breakfast according to one article on LinkedIn by Bill Gates. Daily McDonalds, hamburgers, and a lifelong love of (addiction to?) Coca Cola.

So while the definition of eating well has always changed, I’m not sure it was ever what Buffett reportedly does. And if Buffett’s diet is actually as reported, he is likely an outlier in terms of typical effects of such a diet into old age.

“If I eat 2,700 calories a day, a quarter of that is Coca-Cola. I do it every day.”
