Unfortunately, like all simple things, the devil's in the detail. You can vary the left hand side of the equation (diet) or the right (excercise), or both simulaneously (my preference). And not all (energy in)s are equal - you can have two diets with similar caloric intake, but if one has high fat content there's other issues generated.
Don't take this the wrong way - I'm not into guilt-trips, but I found the initial picture pathetic, in the original meaning of the word. There's a lot of reasons why someone gets morbidly obese like that poor woman, and a lot of it's emotional in my experience. You are of course responsible for your own actions, and every action has a reaction and all that. But horrendous childhoods, low self esteem, abuse, lack of support, social isolation - they can all sow the seeds. And once you pass a certain point, it's very hard to go back.
Sorry - I know that was really preachy...
