Social factors affecting obesity?

I struggle with sociology, just wondering if anyone could help me giving me some ideas to get me started?


Our society has a comfort level that eliminates the need for any physical activity. With plentiful food and no requirement for physical activity, obesity has become a problem. When food was not as plentiful and work required more physical activity, obesity was not a problem. Man has made a good effort to eliminate the level of physical activity required to produce goods and services by creating machines that do the physical work.
