I agree with you that obesity is a choice. I also think that obesity has much more to do with eating too much and less to do with exercising too little. However, I think fat people have a right to be fat.
I agree that you can always out-eat an exercise program. Easily. In fact, that may be one of the more self-defeating myths out there... that if I exercise hard enough I can eat whatever I want.
My life is spent in a struggle not to eat too much, too often. I’ve recently realized that that’s not likely to change too much. And I don’t know which side is going to prevail.
