How is WW different than Noom?

WW is Weight Watchers Reimagined, and the #1 Program for weight loss. myWW™ is our most customized plan ever!


WW is the #1 Doctor Recommended Weight Loss Program*



U.S. News & World Report Rankings*

In 2019 WW was ranked #1 Best Diet for Weight Loss for the 9th consecutive year.

No 2019 ranking.


More than 50 years of history successfully scaling effective, accessible, science-based weight management.

Noom was founded about 10 years ago and launched the Noom App in 2010.

Scientific Evidence

100 published studies conducted in 5 countries on 4 continents have rigorously evaluated the WW program and demonstrated its efficacy. 

Numerous randomized clinical trials have shown that WW is more effective for weight loss than self-help, university-based treatment, and physician advice. WW has been shown to be effective among individuals with diabetes and prediabetes. 

Research cited by Noom admits having “limitations,” including that one study was “not a randomized, controlled trial, and thus comparisons with a control group could not be made,” and that in another study “all of the data including food and exercise were self-reported and prone to social desirability which may lead to inaccurate data.” Some other research describes limitations (e.g., “limited generalizability,” “uncontrolled,” “pilot,” etc.). The only randomized, controlled study was limited to patients with eating disorders. 

How does it work? WW incorporates healthy eating, activity and mindset. Our SmartPoints® system assigns one easy-to-understand number to foods and beverages that takes into account calories, saturated fat, sugar, and protein.  Members are given a daily SmartPoints budget, as well as additional weekly and rollover points for added flexibility.  Members  can spend their personalized SmartPoints budget on any food.   WW recognizes the benefits of regular activity and encourages members to find ways to move for pleasure.  With FitPoints 2.0, members can create  a personalized activity plan to help them on their journey.  Building healthy habits is also about being in the right frame of mind.  WW provides tools, including its app, for members to use anytime, anywhere to shift to a more helpful mindset.  Users are given a personalized daily calorie budget based on age, sex, activity level, and weight loss goals. Foods are grouped in colours (green, yellow and red) to help guide users towards healthier choices. Noom also uses psychological strategies including with messaging via its app to help users manage  the mental and emotional barriers to weight loss.
What can I eat? Everything's still on the menu. In fact, there are over 200 ZeroPoint™ foods that you don't have to weigh, measure, or  track.   These foods form the basis of a healthy eating pattern.

No foods are off limits. Foods are grouped into a traffic light system of  green, yellow, and red foods.  Green foods are lowest in caloric density and/or contain the highest concentration of healthy nutrients; yellow foods which have more calories and/or less healthy nutrients per serving than green should be eaten in moderate amounts; red foods which are highest in caloric density and/or have the least healthy nutrients are meant to be eaten with less frequency and in smaller amounts. 

How can I access the program?
