MIAMI BEACH, FL - JULY 18: Jeff Baughman bites into his double cheeseburger with a Super Fries and a Super Coke on July 18, 2002 at a McDonalds in Miami Beach, 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)
