Probably one of the most versatile fall foods around, nutrient- and fiber-rich apples can be used in everything from beverages to main courses to desserts. Apples are the perfect addition to your weight-loss plan, says Karen Langston, a certified nutritionist and board member of The National Association of Nutritional Professionals.
