MIAMIL – JULY 18: A double hamburger is seen on July 18, 2002 at a Burger King in Miami, Florida. The health effects of an American diet of super-sized fast foods are becoming apparent as increasing numbers of children and adults are being treated for obesity. Studies seem to point to the fact that many overweight children and adults get a large portion of their calories by consuming too many sodas and sweetened juices and beverages. Sweetened drinks + “super-sized” meals + the convenience of fast food + a decrease in physical activity = a recipe for obesity. (Photo by Joe Raedle/Getty Images)
