Now many believe it is a combination of lifestyle factors and genetics, as well as a propensity for some people's bodies to be hyper-efficient at storing calories. This tendency would benefit people in societies where starvation is rampant but is a huge problem in developed countries where food is plentiful and lifestyles are increasingly sedentary, Vernon said.

This doesn't make sense. If genetics was really such an important factor you would have seen this phenomenon much earlier. People have had the opportunity to eat to overeat a long long time. It can't be genetics. There always existed an elite who did not have to exert themselves in any way and who had access to all the food they want. They had servants to do the work, and carriages to cart them about. Yet you simply didn't see obesity as you see it now.

As for excercise ... yes people exercise less than ever, but there isn't such a huge difference from before. Not everyone had to work on the farm. Why the explosion of obesity now.

It cannot be anything else than FOOD. The answer is staring them in the face, if only the could see past their precious attachement to the Pyramid God
