The trick, however, is to not overdo the snacks. Here are some guidelines for weight loss snacks:

Women should strive for two snacks per day.If you get very little exercise and are over 50, limit yourself to 200 calories of snacks per day.If you are very active and younger, you can have two 200-calorie snacks per day.If you find that you are having more than a three pound a week weight loss, choose from the higher-calorie snacks or add additional snacks to your daily menus until you maintain or lose at a rate of no more than two pounds per week.
