WELCOME TO THE WW SCIENCE CENTER

WHERE TRUE BEHAVIORAL CHANGE BEGINS.

The health and wellness-sphere is loaded with fads, trends, and fake news. The
WW Science Center is the antidote to all that. We are, and always will be,
rooted in nutrition and behavior change science. And we use this research—along
with expert insight—to help members build life-changing habits and reach their
weight-loss and wellness goals.

As science evolves, so do we! That’s why we’re excited to introduce our most
individualized program yet: the NEW! PersonalPoints™ Program.

> 


GET TO KNOW OUR PERSONALPOINTS™ PROGRAM

With WW’s new PersonalPoints Program, members receive a personalized plan
designed specifically for them by our nutrition experts—no two plans are the
same! And “personalized” isn’t just a buzzword. Research has proven that
individualized approaches lead to greater engagement and greater weight loss
than a one-size-fits-all approach.

> “After working in this field for over 30 years, I’ve seen countless ideas
> about how to make losing weight easier and more sustainable, but I have never
> seen something like this new program.” —Dr. Gary Foster, Ph.D., WW Chief
> Scientific Officer

How the NEW PersonalPoints Program works:

 * Science, simplified. We use the latest nutritional research to guide members
   toward a healthier pattern of eating, nudging them toward foods that are
   higher in healthy fats, fiber, and protein and lower in added sugars and
   saturated fats. An updated food algorithm distills calories and complex
   nutrient data down to one number—a food’s PersonalPoints value—to make eating
   healthier easier.
 * PersonalPoints tailored for real life. When members join WW, they answer a
   series of questions designed by our nutrition and behavior change experts to
   help us understand which foods they love most and reach for often. They’ll
   then receive a PersonalPoints Budget and ZeroPoint™ foods list (foods members
   don’t need to track) that’s customized to the foods they love.
 * For the first time ever, members can add Points! Behavior change science
   tells us that when we receive positive reinforcement for doing something,
   we’re more likely to repeat it. And repetition is what creates habits. To
   encourage good-for-you habits, WW’s PersonalPoints Program features a first
   for the weight-loss industry as a whole: Members’ Budgets now grow when they
   eat non-starchy veggies, drink water, and get active.
 * Support that goes beyond the scale. The program also helps members move more,
   shift to a healthier mindset, and sleep better. Our award-winning app is
   packed with helpful tools and resources, including 24/7 live Coaching
   sessions, on-demand meditations and expert-led workouts, 5-minute Coaching
   audio lessons, strategies to improve sleep, and more.

HOW WW EXPERTS DEVELOPED THE NEW PROGRAM

To deliver on our mission is to help members develop healthy habits—and ensure
that only the best programs reach our members—WW experts spent over two years
rigorously testing the new program with more than 6,000 members across the
globe. Here's how:

 * WW’s dedicated Science team researched the latest in nutrition and behavior
   change principles to better understand what might make a member’s journey
   easier.
 * Using those learnings, we updated our Points formula and created
   individualized plans that are attune to how people really live.
 * WW then tested our new program with members to get their feedback, followed
   by a 6-month clinical trial with over 150 participants conducted by
   independent researchers at the University of Connecticut.

WW’S COMMITMENT TO SCIENCE AND EFFICACY

Since 1963, WW has been rooted in science. Today, the WW program is guided by
our Science team—a 12-person-strong group of innovators, including
psychologists, registered dietitians, behavioral scientists, and other experts.
The team regularly partners with universities to conduct clinical research.

Because of this commitment, WW is one of the few programs that fulfills all of
the criteria that expert panels deem necessary in order for behavioral lifestyle
weight-loss interventions to be effective.1, 2 These panels include the United
States Preventive Task Force, The Obesity Society, the American College of
Cardiology, the American Heart Association, UK National Institute for Health and
Care Excellence, and the Australian Government’s National Health and Medical
Research Council.

That’s not all: Over the past five decades, more than 130 published papers and
randomized controlled trials have examined the efficacy and impact of the WW
program. WW is the #1 doctor-recommended weight-loss program according to a new
survey of 14,000 doctors†. And for the past 11 years, WW has been named the #1
Best Diet for Weight Loss by U.S. News & World Report.

SIGNIFICANT & EFFECTIVE WEIGHT LOSS

WW has been evaluated across the world—the United States3,5,7, United
Kingdom, Germany4,12, China9, and Australia4—and found to produce significant
weight loss in each country. 

In numerous randomized, controlled studies, WW was found to be more effective
for sustained  weight loss—defined as 6 to 12 months—compared to:

 * Physician counseling: WW is 2 times more effective for weight loss than
   physician counseling.4
 * Professionally delivered program: WW is 3 times more effective in producing
   10 percent weight loss than professionally delivered programs.5
 * Other commercial programs: Out of 141 commercial and proprietary weight-loss
   programs, WW was identified as one of two programs clinicians should
   prioritize for referral due to our sustained weight loss and
   cost-effectiveness.6

Additionally, WW has been evaluated and found to be effective for chronic health
conditions, such as :

 * Prediabetes—WW is 27 times more effective for weight loss than a
   self-initiated program and produced greater improvements in glucose control
   in those with prediabetes.7
 * Type 2 diabetes—WW is 2 times as effective for weight loss than standard
   diabetes nutrition counseling and education, and produced greater
   improvements in glucose control in those with type 2 diabetes.8

COST EFFECTIVE

In a review of weight-loss programs, WW was shown to be the most cost-effective
when compared to other clinically proven nonsurgical programs such as Vtrim,
Qysmia, Orlistat, and Jenny Craig.10 

†Based on a 2020 IQVIA survey of 14,000 doctors who recommend weight-loss
programs to patients.
