WeightWatchers® Science Centre | WW Australia
Welcome to the WeightWatchers® Science Centre
Where true behavioural change begins.
The health and wellness-sphere is loaded with fads, trends, and fake news. The WW Science Centre is the antidote to all that. We are, and always will be, rooted in nutrition and behaviour 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.
WW’s commitment to science and efficacy
Since 1963, WeightWatchers 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, behavioural 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 behavioural lifestyle weight-loss interventions to be effective. 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 randomised controlled trials have examined the efficacy and impact of the WW program. And for the past 13 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 States, United Kingdom, Germany, China, and Australia—and found to produce significant weight loss in each country.
In numerous randomised 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.
- Professionally delivered program: WW is 3 times more effective in producing 10 percent weight loss than professionally delivered programs.
- Other commercial programs: Out of 141 commercial and proprietary weight-loss programs, WW was identified as one of two programs clinicians should prioritise for referral due to our sustained weight loss and cost-effectiveness.
