October 5/Orlando/Chicago Sun-Times -- The vast majority of adolescents underestimate the number of calories contained in the meals they purchase at fast food restaurants, researchers found.
Of those ages 11-20 surveyed outside of fast food chains in four U.S. cities, 80% underestimated the actual calorie content, and 30% misjudged the amount by at least 500 calories, Jason Block, MD, of Harvard Medical School in Boston, reported at the Obesity Society meeting here.
