What's feeding America's obesity epidemic?

 Experts have blamed everything from junk food, sedentary jobs, failure to exercise just self-control. For years, magazines, websites, and other media have been slammed for using pictures of skinny models. Some say those images promote eating disorders by giving young women a wildly unrealistic view of the female form. Now the Yale doctors say photos and videos that depict obese people stuffing their faces with fatty food or sprawling self-indulgently on a sofa are pushing fat people toward even bigger bodies.
