Being poor doesn't make you fat per se, but if you look at most stats, higher social levels(whatever that means in each country) usually means less obesity. When I worked in construction, most people were eating an absolute crap and were often overweight. Then I joined a professional services company and I literally walked into an office of 50 or so people, where everybody was slim and most people ate pretty healthy, home made food.

There are lots of factors why that's the case,but to say it's not happening like this wouldn't be right either.
