In my experience it is a horseshoe, people that eat out for every meal tend to be either on the high end of the income spectrum and thin or the very low end and obese. These are broad strokes, but my experience in rural America and in SF bears this out, rich people eat out very often and tend to be fit and the very poor also eat out more than average but tend to be obese. Everyone else is in the middle.
