Researchers at the University of Exeter in the UK have found that a walk of just fifteen minutes can reduce chocolate cravings. Following three days of abstinence, 25 regular chocolate eaters were asked to either complete a 15-minute brisk walk or rest, in a random order. They then engaged in tasks that would normally induce chocolate cravings, including a mental challenge and opening a chocolate bar. After exercise participants reported lower cravings than after rest.
