A lot of the difference between urban US and a lot of rural areas is the urban tend to walk more. IMO its a lot easier in the burbs and rural areas to take the pickup to the store then walk there. Most work is more machine work than used to be the case. When was the last time you saw crops harvested by hand or ditches dug by hand? Before you say anything, I am currently an old fat dude who is not in shape. My excuse is medical problems that make me less moble. A gym is good, but it only lasts so long and then back to your cubicle or easy chair. People have access to all kinds of food all the time-in the old days fast food did not exist, pizza was not found in the freezer. In the 1950's I knew a pair of brothers who were about 350 each. They were the biggest people in town. Now days they would not stand out.
