Fast food is arguably one of the biggest parts of American culture. No, we literally mean it. The oily grease runs through our national veins. But fast food — the Big Macs, KFC buckets, Taco Bell tacos, and Pizza Hut pizzas — is a part of athlete culture... or is it?

Athletes may eat fast food served to them, like, say, when the Clemson Tigers football team visited the White House in January 2019. However, fast food comes with a lot of fat, grease, and sugar, so it comes with negatives, too.

With all that said, we're going to go over 10 athletes who like fast food and five who can't stand it.
