An average 10km run burns 600cal. Sure just living burns 2000cal, but its a noticeable change. In Addition, for most people its much easier to track their exercise, than pedantic tracking calories.

A casual search on google says a chocolate bar is about 500~600 calories ... so you could maybe skip that chocolate bar and not feel the need to run so much.

(Not to totally give up exercise tho' - there are other health benefits besides losing weight)
