Adjust for IQ and that correlation goes away.
I'm not saying fat people are all dumb, there are a lot of factors that can affect that, but the more intelligent you are the more likely it is you will find a way to lose weight.
I also suspect that by fat they mean obese. And you do have to be pretty stupid to let it get that bad.
Accurate. IQ predicts obesity, and stupid people earn less.
