Britain’s Royal Society for Public Health is arguing that food labels should include information on how much exercise is needed to burn off the food’s calories. The Society’s chief executive has called for introducing “activity equivalent” calorie labeling, with symbols that would show how many minutes of certain types of exercise are required to burn the product’s calories. But Mashable cited Dr. Jemima Stockton of University College London’s Epidemiology and Public Health Department as saying that approach wouldn’t work, since people burn calories at different rates for the same activities. She explained, “For example, a heavier person will burn the same number of calories in a weight-bearing physical activity like jogging in less time than a lighter person because they will be carrying more weight.”
