Volumetrics is an eating plan championed by Barbara Rolls of Penn State University, and it's based on getting more mileage out of low-density foods. For example, a huge salad—or in this case, nearly 4 cups of popcorn—will leave you more satisfied than a square of chocolate, and for far fewer calories. If you're someone who gets depressed by measly portions, reach for healthy snacks that have a high water content like fruits, veggies—or our favorite crunchy munchie: popcorn. For a pre-popped variety, we love SkinnyPop because it's free of additives and tasty without being too salty.
If you're craving something sweet and sinful, grab this mini pack of jelly beans. With just 4 calories in each bean, they're the slimmest way to enjoy cotton candy, toasted marshmallows, and strawberry shortcake. As an added bonus: Jelly Belly uses real fruit purees to flavor their beans. It's still candy in every sense, but it's certainly the lesser of many sugar-loaded evils.
Oatmeal is a complex carb, meaning it helps fill you up without spiking your blood sugar. Plus, it's a good source of fiber and eating more fiber helps people lose weight and keep it off. While we think of it typically as breakfast, a small bowl of oats makes a hearty, filling and delicious snack. To make this snack more convenient-keep a packet or two of unsweetened instant oatmeal at your desk or make overnight oats in a mason jar.
