Every body is different. Some people's norm weight is heavier and others' are lighter. I agree that for some people food has an emotional component that could use the guidance of a therapist, but some people are just heavier and that's fine. There could be no exercise, eating, or emotional problem- just the way their genes deal with the food they intake. It's unfair to look at every bigger person and assume they haven't worked out some "issue" that thin people have "worked hard to overcome." Most of the time it's just genetics.
