Keep Track of Snacks
Eating out of the package is one of the easiest ways to go overboard on calories -- before you know it, your big bag of chips will be empty. Snacks that come in 100-calorie packs can take the guesswork out of portion sizes. Or you can put the exact amount you want to eat on a plate. If you're on the go, use a convenient container; for nuts, pack a 1-ounce portion, and use a 1-cup holder for popcorn, whole-grain crackers, or fruit.
