Yes control has a big deal to it but theres more. Fat people have to eat and exercise to loose the weight and keep it off. Then theres skinny people who can do whatever they want and won’t gain any weight. My brother eats alot but he also works pretty hard, then me I eat maybe 2 small meals a day but am pretty lazy. Both of us are 5’6" and under 130lbs. I wouldn’t even be able to do the ‘supersize me’ diet because I just can’t eat that much. If I get a combo meal, most of the time I don’t even eat the fries because I’m full. I don’t eat unless I’m actually hungry and when I do eat, I eat real meals. I rarely eat snacks.
