Wow! And that's on top of the German tradition of possessing robust mid-sections. But, yeah I see a lot of fatsos around down in the valley towns. Teens and children even. Has nothing to do with black or white. People just pound junk food and sit around on their asses all day. I never see them out on the trails or swimming in the many lakes around here. Just the 40 and up crowd - well, not crowds. More of an East Coast thing. I don't see as many fatties in CA or CO. Quite the opposite.
There's a direct correlation between the lack of open space an obesity. A study of large cities a few years back showed San Diego that showed the highest amount of open space and lowest obesity where Philadelphia had the least open space and highest obesity.
That said, I fully believe the largest contributor to obesity is processed foods as the chemicals in them throw off the body's ability to adjust its metabolism.
