The Weight Watchers Core Plan instructs participants to choose snacks, meals and beverages from an approved list of generic foods and branded items. Don't worry about counting points; just stick to the list and stop eating when you have satisfied your hunger. The program promotes weight loss by eating high volumes of low-calorie foods and promises the same weight loss (1 to 2 lb. per week) as when counting points.
