The role of physicians in promoting weight loss

There are numerous costs resulting from being overweight or obese. A relevant question is how to effectively reduce rates of obesity. I examine the effect of advice from a physician or heath care provider to lose weight on individual weight outcomes using survey data. I account for selection bias using a control function approach and rely on data restrictions to control for simultaneity. I find robust results indicating that advice has a significant effect on weight loss. Several studies suggest physicians may not adequately advise their patients about weight loss. The results of this paper highlight an important opportunity for physicians to advise at-risk patients.
