It's the stopping when you are full that is the key. I cannot eat past fullness, and I have never had a weight problem. I don't even own a scale. But most people seem to be able to keep eating past the point of fullness, and that's how they get fat. And once you get fat, it's hard to lose weight, since fat is the body's long term energy storage system.
I often wish I could eat more than I can, that is for sure.
Agreed on all counts....eating past the point of fullness goes against the body's signals that it's sending you...."STOP EATIING!" :-)
I think that many overweight troubles are as a result of intentionally overriding the natural signals that God put in us to to help us keep healthy.
