I got fat because I ate too much. That means I ate more than I burned off. Overweight was the result.

But I often hear of overweight/obese people who supposedly didn't get that way from overeating. Hard for me to believe. What percent of the overweight population falls into that category?

I have a little hypothesis that if anyone loses weight from the gastro-instestinal surgery, then they were only fat in the first place because they ate too much. If all the surgery does is reduce the amount they can eat, then they didn't "need" the surgery at all. They only had to eat less.

What do you think?
