Generally speaking, people from the South tend to be fatter while people from the North-East an West are a bit leaner. However, I think that American obesity is overrated. Sure, we're not thin, but the rest of the world isn't exactly svelte either. According to the links below, even the fattest parts of America are no match for various Mediteranian nations.
