Apples are one of the few fruits that contain pectin, which naturally slows digestion and promotes a feeling of fullness, according to a study in Gastroenterology. In fact, people who ate an apple as part of a meal felt more satiated and ate less than those who consumed a calorically equivalent amount of juice and applesauce. "Whole apples take a long time to eat for very few calories," says Susan Roberts, PhD, professor of nutrition at Tufts University. Your body has more time to tell your brain that you're no longer hungry. That means you can eat lots of this low-energy-density, high-satiety fruit and avoid feeling deprived while losing weight, adds Roberts.



Feel even fuller: Add apple chunks to oatmeal or salad, or slices to a turkey-on-whole-wheat sandwich.
