Pears: Why you need them: Pack the fruit bowl with pears if you want to lose pounds, reports a study out of the University of Rio de Janeiro. In the study, which was published in the journal Nutrition, women who ate three pears a day consumed fewer total daily calories and lost more weight than those who didn’t. Rich in fiber (one pear packs 15% of your daily recommended amount), pears help you feel full and keep you from overeating.

Best way to work them in: Eat a pear before a meal to help curb hunger. Ditch the peeler, though; most of the fruit’s beneficial fiber is in the skin.
