Our Story
Since 1963, Weight Watchers® has been built on one enduring belief: real change happens with support.
While the science of weight health continues to evolve—from nutrition frameworks to GLP-1 medications—one truth remains constant: sustainable success requires behavior change, expert guidance, and accountability fueled by community.
Our Purpose
We help people succeed on their journey—not just to lose weight, but to keep it off and live healthier lives. Our evidence-based programs drive meaningful outcomes and support long-term health by combining medical innovation, behavioral science, and human connection—giving members the tools, support, and confidence to move forward with self-compassion.
Our Vision
Our vision is progress that lasts, care that adapts, and success that feels sustainable.We envision a future where weight health support is integrated, personalized, and deeply human—where no one, on or off medication, is left on their own, but supported with guidance, structure, and community.
Our Approach
GLP-1 medications are powerful tools—which is why we provide access to board-certified clinicians who can prescribe GLP-1s to eligible members.* But while these medications can help support weight loss results, they do not replace the need for healthy habits. Sustainable weight loss still requires nutritious eating, movement, community, accountability, and education. We combine access to medication with evidence-based behavior change, smart technology, and supportive community to help members succeed at every step. With expert guidance, flexible structure, and a culture rooted in kindness and respect, we help people not only lose weight more effectively—but improve their nutrition** and overall quality of life.***
Our Promise
Our promise for the next 60 years is simple: blend science with kindness. Meet people wherever they are—on a screen, in a workshop, or on a walk—and use every tool, from medication access to nutrition and data, to make change more personal and human. And through it all, keep the heart of Weight Watchers rooted in compassion and community—because no one should have to walk this path alone.

About Us
Weight Watchers is a global leader in weight management, trusted for more than 60 years to deliver results on the scale and beyond. Research and real-world outcomes show that members following the Points Program lose 3.5x more weight than standard nutritional guidance^, while members prescribed GLP-1 medications through the Med+ Program lose 30% more weight than select competitors^^. Across Programs, members also experience meaningful improvements in well-being and quality of life†. We’re proud to lead with science, compassion, and respect while building the future of weight health around what truly helps people thrive.

^^Based on an internal analysis of 3,260 Weight Watchers Med+ members prescribed a GLP-1 medication and self-reported both a starting weight and a weight at month 12. On average members lost 21.0% of body weight in 12 months. Compared to an analysis of (i) 17,475 Calibrate members who received at least one month of GLP-1 medication, were enrolled and had a valid weight at month 12, and lost 15.7% body weight in 12 months; (ii) an analysis of 500+ Form Health patients who received intensive lifestyle therapy and semaglutide, and had an average weight loss 13.6% body weight in 12 months; and (iii) an analysis of 1,812 Hims & Hers members prescribed a compounded injectable GLP-1 medication through the Hims & Hers platform, reported their weight at month 12, and lost an average of 12.2% body weight in 12 months. Cohorts differed in inclusion criteria, medication type, and follow-up duration. Not randomized, controlled clinical trials. Self-reported outcomes have not been independently verified. Individual results may vary.
