Since the mid-1980s, Americans have gotten fatter. Numerous policy initiatives have failed to reverse the upward trend in body weights, and the Center for Disease Control labels obesity as an "epidemic" generating enormous health costs. Plaintiffs' lawyers and public health organizations are devising litigation to address this problem with the argument that false advertising contributes to or causes many weight problems. On the first panel of this event, scholars will discuss their empirical research into the causes of U.S. obesity, which include declining food prices and a decrease in on-the-job physical activity. Speakers on the second panel will discuss the legal basis for obesity suits and the merits of regulating and legislating in this area.
