Damn, I can relate so well. I've always thought that obese people were unattractive, unhygienic, and lazy, but in-terms of core attributes/traits, those specific undesirable qualities didn't bother me that much.  However, after having dealt with a fat friend (6'0", 300+ lbs), & after getting to know him better over a prolonged period of time, I realized that he was (1): EXTREMELY dishonest (aside from a plethora of other lies, he literally lied to my face, just to save 5 minutes of his time), (2): EXTREMELY narcissistic/entitled/selfish (his father is a multi-millionaire who is like 3rd or 4th in the chain-of-command at "Planet Fatness"; so it's obvious he was spoiled), (3): possesses an insane lack-of-awareness & uses every-type of mental-gymnastics to rationalize his immoral and/or self-destructive actions, (4): despite being aware that he's fat (told me multiple times that he's going to start dieting & running), he doesn't possess a milligram of self-discipline/self-control, and thus eats absolute shit all-day, every-day while never exerting himself physically whatsoever. [TL;DR]: Being fat is not only physically unhealthy & unattractive, but more importantly, it's merely an outward reflection of extremely unhealthy and unattractive mental qualities as well (which after my newfound awareness of this simple fact they don't want to ever admit to, is why I joined and now love, FPH).
