How to fix it: If you have a really strong craving, it's fine to indulge –- a little. Try to prevent yourself from going overboard by placing only a certain amount of food in front of you. Put potato chips in a small bowl rather than eating them right out of the bag, for example. This is especially important after a tough run or workout, when you may feel that a big-calorie binge is justified. In reality, you could end up eating way more calories than you burned during your run.
