Very rarely do fat people actually get that way by cramming fast food and abusing their bodies. They get there through genetics, or thyroid issues, or antidepressants (hi there!)

Gods, yes. I so hate that antidepressants do this. I'm on them for nerve pain, and probably will be on them for the rest of my life. I love the fact that I'm mostly pain free now, but they made me put on 50 lbs, which I hate. I wasn't skinny by any means before the meds, but I was very happy and comfortable with the way I looked, and unfortunately, the meds are making it impossible for me to get back there. *grumbles*
