Numerous studies (See the first chapter of "Why we get Fat, by Taubes) have shown that Obesity is a disease of poverty. The food that keeps you lean (protein/fats) is expensive. Carbs are cheap. Poor people eat carbs. Rich people eat steak, chicken, fish. There is no significant research that shows adding exercise to an overweight person's lifestyle will significantly reduce their weight - typically just increases their appetite.
