When you find yourself reaching for a snack—WAIT! Are you really even hungry? Or are you simply eating out of habit? Next time you find yourself gravitating toward a junk food fix do a short burst of physical activity instead. A dozen jumping jacks, 15 crunches, a walk around the block… you get the idea! By the time your heart rate returns to normal you will find that your craving has passed—and not only did you save yourself from empty calories, you burned extra calories as well!
