I admire people who work hard and get shit done. I don't admire people who accomplish things but use it belittle other people, and insinuate that the opinions of those who haven't had the same success aren't as valid. I think accountability is great, but using appearance as a gauge of credibility is going to make you a victim of the next Ted Bundy.
I'm about 15 pounds overweight at this point, and the rest of this weight is really, really hard to get off. I get the sense that most of the posters saying that 'fatties are just making excuses and not trying hard enough' are men. I don't think I am fit, but I have healthy habits (primal diet, regular exercise, limit alcohol, try to sleep well, meditation to deal with emotional issues), and I have very good health markers (doctors are always so surprised at my blood pressure, and ask me if I exercise). At this point I'm more worried about dying early due to the harm caused by stress and negativity and being an angry person in general, not due to 15 extra freaking pounds that I'm already aware make me extremely unattractive to most of the men I see every day.
