Learn Portion Control

Meal-replacement bars are a temporary tool to help you manage your weight. They work because they prevent you from underestimating how many calories you're getting. To keep the weight off, however, you must learn proper portion sizes so you don't gain the weight back when you return to eating regular foods. Once you're familiar with how recommended portion sizes look, you'll remember how much to dole out for staples such as protein, fruit, vegetables and whole grains. Create a cheat sheet to stick on the fridge as a reminder of the appropriate portion sizes.
