I would agree to a point but in my experience genetics is the overriding factor. BTW, I don't really weigh 450lbs. That was a joke. Not necessarily a funny one, though!

Having gone from super skinny to pretty fat and then back to normal width I know for a fact that THE overriding factor is diet and exercise. I was too poor to eat when I was super skinny, got a good job and good money and good food and got fat, then took control of what I was eating and started getting plenty of exercise to get normal.
