A lot of women feel they get very hungry between meals and need something to tide them over. Go for it. Snacking is a great idea because it provides more opportunities for women to get the foods they need. A reasonable snack contains anywhere from about 80 to 120 calories. That includes a piece of fruit, an ounce of cheese, 2 to 3 tablespoons of nuts or a small container of yogurt. Don’t forget those baby carrots—just go easy on the hummus and other dips, which tend to have a lot of calories.
