Researchers at the Nutrition Obesity Research Center at the University of Alabama at Birmingham have listed unproven assumptions and myths about dieting in a report that finds science does not back up many long-held ideas about physical education, crash diets, quick fixes, motivation and even daily weigh-ins. Other obesity experts applauded the report in The New England Journal of Medicine, including Madelyn Fernstrom of the University of Pittsburgh Weight Management Center, who said ideas about obesity are "spinning out of control.”
