5. You reward yourself with food.
Do you allow yourself to have that extra piece of pizza or order that dessert when dining out because you "went to the gym" earlier? If so, you may be undoing all of that good calorie-burning with too many treats.

Get-Results Remedy: Familiarize yourself with the calorie contents of your favorite foods—and find out how many calories you're really burning through exercise. (SparkPeople's Nutrition Tracker andFitness Tracker will help you learn!) Remember that while you may have run 3 miles at the gym, that only burned 300 calories, which isn't nearly equivalent to the calorie count in that brownie sundae you ate later. Focus on how good exercise makes you feel rather than what it allows you to eat after; and choose foods that fuel your workouts, rather than the other way around.
