Getting over obesity takes more than a diet change

Have you known someone (even yourself) that has become morbidly obese and has probably thrown every trick in the book to become "normal" again regarding weight?

Although obese people in the U.S. (and in schools especially) are mocked way more than supported (in a sign of deteriorating mentalities in this country), the struggle to transition from obese to normal is the hardest struggle to make in life for many people. It's way more than radically changing one's diet from what I have seen.

Are the emotional barriers and societal stigmas too hard to overcome for many? Sure -- and then there are some that blast past those obstacles and retake control of their lives. That has to be one of the hardest things ever to face a human being. What are your thoughts?
