Pears deliver a dose of fiber (about 5.5 grams per medium-sized fruit), which helps keep you satisfied long after you eat them. But that’s not where their fat-fighting power ends. A Brazilian research team found that a group of women who included pears in their diet each day lost more weight than the group who included oat cookies—even though the pears and the oat cookies had the same number of calories. Slice pears up and dip them into nonfat plain yogurt for a snack, dice them and add them to salads, or poach them for dessert.
