Well, I would disagree with the assertion that wanting to look good HAS TO BE for someone else's benefit... losing weight, at least for me, is more than just so that I can look good to other people -- it's so I can feel better, about myself -- emotionally, physically, everything. My motivations to lose weight are 100% for my benefit.
In terms of health... well, I'm 24 years old now. When I first began taking my weight problem seriously, I was 19 (about to be 20). Even at 264lbs and 5'4" tall, although I felt terrible about myself and all, I had normal blood pressure, normal cholesterol, no diabetes or heart problems, no breathing problems, no knee or joint problems, etc etc. I wasn't (yet) experiencing any negative health affects of being obese. That's not to say that, given time and some aging, i wouldn't have developed them, but at that point, I had no immediate health reasons to lose weight. Also, when you're 19... I mean, I'm a pretty cautious person, but who worries about what they're health will be in middle age when they're 19 years old?
But even though 99% of my desire to lose weight was for "superficial" reasons -- wanting to look and feel better physically -- I still did it completely and totally for myself.


great comment, Chickie.
The more you get involved the more you'll see that we all have different things that are making us want to lose the pounds but it's all for the common cause!
