Swap For Less Calories

Should you stick with low-fat yogurt or go Greek? You might want to pledge with Chobani's vanilla nonfat Greek yogurt -- it'll save you 10 calories a serving over Stonyfield's vanilla lowfat. This Chobani flavor has more than double the protein and less sugar, too.

Small, consistent calorie reductions will lower that number on the scale. Check out FitSugar's five popular food swaps to get taut and stay that way.
