One can of cola = one hour”s run: Exercise labels could be “more effective than calorie counts” Warning labels that explain how much exercise is needed to run off the calories in junk food are far more effective than traditional counts, researchers say. It was found that teenagers who were shown the warnings on fizzy drink cans – which stated an hour”s run would be needed to get rid of the calories – were half as likely to drink them.
