Weight Watchers Report Finds Integrated GLP-1 Support Drives Significantly Greater Weight Loss Than Medication Alone

Weight Watchers’ Med+ members who regularly engaged with their GLP-1 Success Program lost up to 61% more body weight in the first month and 29% more in one year, on average, than those who took medication alone.

Med+ members prescribed medication also reported, on average, over 30% more weight loss than select competitors at 12 months.

NEW YORK, March 11, 2026 (GLOBE NEWSWIRE) -- WW International, Inc. (NASDAQ: WW) (“Weight Watchers”), the global leader in science-backed weight health, today released a GLP-1 Results Report which finds that individuals who take GLP-1 medications and regularly engage in the Weight Watchers GLP-1 Success Program achieved significantly greater weight loss and better health outcomes than those using medication alone. The Weight Watchers evidence review builds on a growing body of research on long-term weight management. For example, a recent systematic review published in the British Medical Journal found that weight regain commonly occurs after discontinuation of anti-obesity medications, while guidance from the World Health Organization continues to emphasize the role of nutrition, physical activity, and other lifestyle factors in supporting metabolic health.

“GLP-1 medications are transforming obesity care — but a growing body of research is proving that medication alone is not enough to create lasting results,” said Weight Watchers CEO Tara Comonte. “To maximize the impact of these medical breakthroughs, Weight Watchers has established an integrated weight health platform that combines medication with structured nutritional, behavioral, and lifestyle supports. The results speak for themselves: members who pair weight loss medication with Weight Watchers’ GLP-1 Success Program lose up to 61% more weight in the first month and nearly 30% more weight over a year, on average, compared to those who do not engage with our approach. Clearly, GLP-1s work better with Weight Watchers.”

Weight Watchers’ Med+ platform, combined with the GLP-1 Success Program, offers access to board-certified physicians, FDA-approved prescriptions, and lifestyle support to drive better outcomes and create lasting habits that can sustain results over time. Designed to specifically address side effects, nutrition gaps, muscle loss, and plateaus, the program helps members stay consistent with the tools they need for success throughout their GLP-1 journey.

The GLP-1 Results Report also identified benefits beyond the scale. Additional clinical and real-world evidence cited show that Weight Watchers programs are associated with improvements in important health and behavioral measures — including hemoglobin A1c, blood pressure, diet quality, physical activity, and quality of life — that support long-term health and sustainability.

In the Weight Watchers app, members can track nutrition, follow guided fitness and strength-focused movement sessions, connect with others on GLP-1s, access dietitians, and discover easy recipes and meal plans — supporting sustainable weight loss and maintaining muscle. The membership also offers a variety of workshops led by physicians, registered dietitians, and Weight Watchers-trained coaches to help members maximize the impact of their GLP-1s.

The key findings in the GLP-1 Results Report illustrate:
