I work in a restaurant. There's a guy that comes in every day and orders a cup of veggies and a cup of brown rice. (most people get a "meal" bowl with mostly rice, some chicken or beef, and some veggies)
A few days ago my boss mentioned that the guy had been getting the same lunch for years, day in day out, and that he (boss) would get sick of eating the same thing every day. I said, "yeah and he doesn't even eat meat!"
Boss replies: "well that's why he's so skinny."
I'm pretty sure he's skinny because he eats like a bird, not because he avoids meat.
