what barriers might be keeping people from becoming more physically fit? These questions point to a host of often-ignored variables that need to be better understood and included in discussions about weight gain and health, like leisure time (or lack thereof), the commodification of food preparation, the changing structure of our food system, food policy, car dependence, over-aggressive marketing of nutritiously shallow food products, changing parental pressures, and barriers to self-powered forms of personal transportation. Doing this shows weigh gain to be a sociological problem rather than product of individual weakness.
