Don't be embarassed, or put yourself down just because you have a medical problem that concerns your weight. I am on steroids and nobody told me that I may gain weight, I went 6'1" 210 lbs to 240 lbs in 2 months. I have lost almost half that now but I just ballooned up and nothing I could do to stop it until it leveled out.
I would venture to say that as far as fat people are concerned that most of them are lazy with low self esteem, and don't even try to lose weight, or if they exercise or anything then they eat it right back. That is my stereotype of fat people and probably is the general consenus. Fuck yea they should pay more for airline seats, and it is like a lot of minorities, they want more than what is all equal right now. We should all be equal no matter of the race, color, religion, body weight or whatever. The only rule would be to people that can't help it to be that way, i.e. medical issues. Fat people may think of themselves as having a mental issue. Well I concur, change your fucking attitude and get a life. Get off your dead ass and get a job, do some work, do something. You know like most people. Only then should you get the respect that you deserve.
Sorry but it is the truth, you have to work off more than you take in, it is as simple as that. No amount of bs diets are going to work until you follow that simple rule. Self control. Self respect.
