Living in the South (in the US), I see obesity on a daily basis. There is very little emphasis on exercise, eating healthy, or health in general. It's almost cultural (sadly). My state leads the country in childhood obesity, so the problem isn't going away.
This is sadly the case for the whole of the developed western World I think. Mass consumerism and advertising coupled with sedentary lifestyles don't help. Although there are seeds of change and its refreshing even to see that Macdonalds is reacting by slightly amending their menus to offer healthy options. Here in the UK there is even a new sugar tax on softdrink companies.
