I don't think it is gene related at all, that link should be quite convincing. Technology has made life easy. The growing amount of office jobs and factories that demand physical work are dissappearing is 1 cause. I've been overweight before(I'm 5'9"), I weighed 210 lbs when I was 17, when I got a physically demanding job at 18 I dropped the weight, went down to 145 lbs. I'm a tone 165 now. I have an over weight mother and an overweight sister, and my mothers side of the family...all her sisters are overweight except one....the one that is the most ambitious. 1 of her brothers is over weight...the laziest. Like Illusional said, fat parents have bad eating habits. If they cook their own meals they cook every piece of fat they can to give it more taste. Feeding it to the children, of course they will get big.
Obesity is controllable, this gene BS is just a cry for sympathy so it will make it "ok" to keep stuffing your face.
Impossible is a word only to be found in the dictionary of fools.
