Randomized Clinical Trial Published In JAMA Network Open Reveals Effectiveness of Widely-Available Commercial Weight Management Program
NEW YORK, Aug. 22, 2022 /PRNewswire/ -- A new randomized clinical trial published in JAMA Network Open found that those engaged in WeightWatchers, a commercially available weight loss program, lost more than twice the amount of weight than those who tried to lose weight on their own. Those randomly assigned to WeightWatchers were also more likely to achieve clinically significant weight loss of five percent at three and twelve months, which can help lead to health benefits - including improvements in blood pressure, blood cholesterol and blood sugar.1
Participants assigned to WW had access to the app and community support - including Workshops, expert Coaches and tools. These participants also experienced WeightWatchers' unique and simplified approach to self-monitoring - with a list of over 200 foods that participants didn't need to weigh, measure or track. As a result, the findings also suggest that programs with lower demands for self-monitoring of nutritious foods can produce clinically significant weight loss.
"Given the global prevalence of obesity, accessible and effective treatment options are needed to manage obesity and its comorbid conditions, but few commercial programs have been rigorously evaluated," said Deborah Tate, PhD, study co-author and a professor of health behavior and nutrition at the University of North Carolina at Chapel Hill. "We are encouraged by these findings which suggest that health care professionals might discuss the potential merits of commercial programs compared with efforts patients might undertake to lose weight on their own for greater likelihood of clinical benefit."
The worldwide prevalence of obesity nearly tripled between 1975 and 2016. In 2016, more than 1.9 billion adults aged 18 years and older were living with overweight and of these, over 650 million adults were living with obesity.2To provide practical solutions for obesity in America specifically, the U.S. Preventive Services Task Force (USPSTF) guidelines state that primary care physicians and other clinicians should offer or refer adult patients with obesity for intensive, multi-component behavioral intervention, of which WeightWatchers meets these standards. However, despite this guidance, most people try to lose weight on their own rather than choosing scientifically proven approaches.
"These study findings are particularly meaningful in a world where rigid DIY approaches, free apps and fads on social media and in the news are common approaches for weight loss," said Gary Foster, PhD, study co-author and Chief Scientific Officer, WW. "This three-country study shows that WeightWatchers is an effective and scalable approach. We're also encouraged that our new approach - where you don't have to track everything you eat and drink - leads to clinically significant weight loss."
The study (Tate DF, Lutes LD, Bryant M, et al. Efficacy of a Commercial Weight Management Program Compared With a Do-It-Yourself Approach: A Randomized Clinical Trial. JAMA Netw Open. 2022;5(8):e2226561. doi:10.1001/jamanetworkopen.2022.26561) was funded by WW International. It was run as an investigator-led trial with all data collection and analysis conducted by the independent research teams, researchers assessed 373 adults with overweight or obesity in the U.S., Canada and U.K.
WW has published 130+ clinical trials, over 35 of which are rigorous, randomized control trials which have examined its efficacy and impact. In addition, WeightWatchers 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.3,4These 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.
