"Body image is particularly important for women. There seems to be a transfer that when women feel bad they eat more. That can have devastating effects emotionally and physically. But for men experiencing obesity, the reverse is true, and obesity seems to be protective against depression. It's the so-called 'jolly fat man' theory, which suggests that overweight people are actually happier."

McCarty said that finding is not surprising since many of the least nutritional items are inexpensive, and low income areas do not have the same sources of fresh fruits and vegetables that more affluent ones have.
"It costs more to eat well," she said.
