Because its obviously a thyroid problem and can be cured by a pill. I have a "relative" that complains about it a lot, while they do next to nothing activity wise at all and think that work is actually "working out". Their job is sitting behind a computer and talking on the phone BTW. The sad thing about it, to me, is that overweight people tend to always put it on "being skinny" versus the real issue which is being healthy.
