The ideal number of daily points is specific to each person depending on gender, weight, weight loss goal, and pregnancy status. Fruits, vegetables, and lean proteins are encouraged. Over 200 foods are considered Zero Point foods and can be eaten without tracking or worrying about portion size.

Weekly meetings are also an important part of the Weight Watchers diet. Meetings include guidance from leaders and support from other program participants. Be sure to seek and follow relevant directions from your physician or other healthcare professional before starting this diet.
