Will employers solve the obesity epidemic?

Federal rules went into effect in July to allow companies to pressure workers to lead healthier lifestyles, as we discuss in "A new solution to the obesity epidemic?" One employer has cut health insurance co-pays for workers who follow healthier lifestyles. Another is penalizing those who smoke by making them pay more toward their health insurance. It plans to extend financial penalties to those who exhibit problems such as high blood glucose by 2009. Is this fair? And will it help the nation's obesity crisis? Post your thoughts here.
