Apples

Apples of all varieties and types help suppress hunger for a number of reasons. First, apples are filled with soluble fiber and pectin, which help you feel full. Apples also regulate your glucose and boost your energy level. Finally, apples require lots of chewing time, which helps slow you down and gives your body more time to realize that you're no longer hungry. Plus, they just taste good!
