Obesity & TeenagersAccording to a new teenage obesity study, over two decades, teenagers have been getting fatter because they have been exercising less, not because they have been eating more. Researcher Lisa Sutherland of the University of North Carolina at Chapel Hill analyzed federal data on the diet, weight and physical activity of teens, ages 12 to 19. From 1980 to 2000, calories eaten rose 1 percent and obesity rose 10 percent, while physical activity dropped 13 percent. Those percentages show that teenagers must have been getting fat primarily because they burned fewer calories. "If caloric intake is flat and physical activity is declining, there is a cause and effect relationship there," Sutherland said. She presented her findings last month in San Diego at a scientific conference of the Federation of American Societies for Experimental Biology. However, although other experts accept the idea that teens have become less active, the experts find it hard to swallow the conclusion that teens have not been overeating as well.
