Bottom line

Easily outshining the competition, Weight Watchers promotes a sensible diet, exercise, group support and a positive attitude that has been proven effective in a variety of scientific studies. There are no off-limit foods, and the program can be customized for those with special dietary needs. In-person, group meetings are the plan's cornerstone, but you can choose to do Weight Watchers without them, using online "meetings" and other support options, as well as food and activity-tracking programs, instead.

Breaking it down


Top-shelf performance. Weight Watchers encourages weight loss with a sensible diet of healthy, whole foods, plus exercise and a positive attitude. It earns top marks from researchers and nutrition experts because there are no forbidden foods. Weight Watchers has been evaluated in a number of clinical studies, with researchers unanimously concluding that it's effective for both weight loss and long-term weight control. Studies show this type of diet program is easier to stick to for the long term than more restrictive diets. It consistently makes the "top weight loss diet" list in yearly diet roundups and expert reviews.

Key features

Group support is key. Weight Watcher's flagship feature has always been social support, which experts say is key to sticking to a long-term eating plan. Traditionally, these were in the form of physical meetings where people weigh in, share tips and stories, and provide general support and encouragement. Those still exist, but for those who can't fit in a meeting, or don't have a facility close by, there is a full range of online services, including support groups, recipes, tips, coaching, and tracking software. There are even mobile apps available. Exercise is encouraged on Weight Watchers and you can earn extra food points through activity, something that earns high praise from experts on obesity and weight loss. Weight Watchers also accommodates those with special dietary needs.

Ease of use

You must track food and activity. Eating on Weight Watchers requires budgeting food points throughout the day, which one expert review notes requires "medium" effort. Points values are assigned to a food based upon a formula that includes fat, sugar, protein and carbohydrate count; in other words, they do the math, but you have to be diligent about keeping track. There are points for specific categories, such as dairy, to help you balance your nutrients, as well as flexible points for treats. You can eat unlimited amounts of fresh fruits and vegetables. If you don't like to track, there is an easier option called the Simply Filling Technique in which you choose from a list of foods and eat until you are satisfied, but not stuffed. There are many cookbooks available that have recipes with pre-calculated points. Weight Watchers easily syncs with several fitness devices to automatically track your activity.

Lifestyle factors

Support comes at a cost. There is a $20 registration fee to join Weight Watchers, although that fee is often waived. An online-only membership is about $5 per week; meetings will cost you about $15 per week, unless they're included in your monthly pass. The monthly passes range from $20 per month to $70 per month, and each level offers more support, such as personal coaching and meetings. While Weight Watchers does cost money, experts and consumer-reviewers agree that compared to diet plans that require prepackaged meals, it's much less expensive and you get a lot for your money. One issue we discovered: the Weight Watchers site says you can "Join for Free," but that's not quite true. You can't join unless you pay at least the minimum of $20 for a one-month plan, or $40 for a three-month savings plan (though the latter is not always offered, so watch for promotions). The "free" is merely a waiver of the starter fee of $20.
