A 38-year-old man in Maryland claims to have eaten almost only pizza for the last 23 years. The surprisingly svelte Dan Janssen grew up eating regular foods, but when he was 15 he became a vegetarian for ethical reasons. There was just one problem: he hates vegetables. Ever since, Dan has been eating two 14-inch cheese pizzas a day and that’s about it. He even worked at Domino's in college to ensure a steady supply. That's commitment!
