To Mr. B Natural, and all the others in here who have never been obese and spew such vitriol. I would like to pass this info on to you.
I am a fat guy. Yes, it is my fault. Certainly, I have the knowledge to change the fact that I am a fat guy.
What I'd like to address is that unless you've been obese (and by obese I don't mean 20-30+ lbs. overweight, I'm talking 100+ lbs. overweight) you have no idea what kind of shit goes along with it. It is certainly easy to say trite things like "put down the fork, go for a jog," but you have no idea how demeaning that is for fat people. You don't understand the vast amount of self-loathing that fat people deal with every day. Just feeling like shit and feeling exhausted from the moment you wake up, until the moment you go to bed at night. The endless cycle of weight gain -> depression -> over-eating -> weight gain that occurs, and the pathetic feeling of satiety you feel when shoving junk food down your gullet, while simultaneously knowing that you're pitiful for doing it.
Yes, I realize that this is all self-induced, and that I wasn't born obese, but I have been obese since around 10-12. I went to Weight Watchers meetings from the ages of 13-16. You have no idea how pathetic it makes you feel being in a room full of middle-aged women and men, it's like looking into a sad crystal ball. Being indoctrinated into the idea of "eat this Snackwell's or Weight Watchers snack, you can have all you want because they are fat free!" I don't blame my mother for this, she really bought into the low-fat diet and to this day I am still trying to convince her otherwise.
TL;DR: To all the people who have never been seriously obese and spout trite shit like, "put down the fork" or "respect your body" or "it's your fault and no one else's" or "of course I've never been obese, I'd never let myself get to that point," you really just don't get it. Also, you are not saying anything that fat people already know. I'm not saying you should simply drop the issue, as health is important, but I would simply ask that people stop de-humanizing fat people. There are people underneath those sweaty rolls of flesh.
