Childhood obesity has become a public health epidemic, and currently a battle exists over how to frame and address this problem. This paper explores how public policy approaches can be employed to address obesity. We present the argument that obesity should be viewed as the consequence of a “toxic environment” rather than the result of the population failing to take enough “personal responsibility.” In order to make progress in decreasing the prevalence of obesity, we must shift our view of obesity (...) away from the medical model to a public health model . At the same time, we must be sensitive to the problem of weight bias.Potential obstacles to taking a public policy approach are identified, as well as suggestions on how to overcome them. (shrink)
