You may have a genetic predisposition to putting on weight, but that is NOT what makes a person obese. Eating more calories than you expend, eating CRAP, and not being active over a long period of time is what makes a person obese. I am absolutely the architect of what I am, today...I take 100% responsibility for it and I know how I got here. I also suffered from depression in my mid twenties...and yes, as a coping mechanism I often ate. But that was because I had begun using food for purposes other than fuel - and that was, again, something I could have chosen NOT to do. But I didn't...I kept doing it, because it made me "feel" good, temporarily. Meanwhile, the pounds just kept piling up.
When you reach a certain level of obesity, I will agree that it becomes almost an impossibility to reverse it based on sheer willpower and self-discipline, alone. Very few people are able to stick it out for the duration of time it takes to lose 100 pounds...let alone 200 or more. But it was the choices they made throughout their lifetimes that got them to the point where they had that problem.
So no, @@Barepigies3, I can't agree with you. It isn't a mystery why we are all obese. We ate too much, and we ate the wrong things, repetitively, over a long period of years. I suggest you start taking ownership of your role in your weight and the behaviors that led to it, because you will find success in long-term weight loss very difficult if you don't.
