Not the opposite, more like an additional point to what I mentioned. The key thing for people reading this who have never gone from fat to fit is that EVERYONE treats you better when you get fit. Men and women, it's not necessarily about sexual attraction people just appear to treat physical attractive people better in all cases.

Yes. This was the primary motivation for me to lose weight last year. Health is a close second, but it's a much more delayed gratification thing vs. seeing the immediate social benefits just 6mo later.

Going from morbidly obese to the mid-range of the normal weight BMI chart in about 6mo time has been absolutely eye opening for me.

It's less about sex than it is about appeal. I don't care so much about being desirable to the opposite sex these days - but the impact of being considered conventionally attractive in pretty much all social contexts is profound.

There certainly is an impact from self confidence, but it cannot explain the whole difference. Humans simply treat people they find attractive differently than those they do not.
