Yes, well, Run for twenty minutes to burn off those excess calories from "unhealthy" foods. This latest initiative intended to encourage people to lose weight [sorry I can't give the link - can some kind person please help me out?] is doomed to failure. Is it supposed to be a shock tactic? An overweight person is not going to run for twenty minutes unless they're conscripts in the army. And besides, when it comes to calories, they're eitherin excess or not.
