Since its foundation in 1963, WeightWatchers has always been rooted in science. Our dedicated Science team uses credible, cutting-edge research to inform our consistently-evolving program, and works closely with the academic scientific community to ensure we meet the highest standards. WeightWatchers is committed to research that addresses knowledge gaps in the field of weight management.
Over the past four decades, over 175 studies have been published on WeightWatchers, including more than 40 publications using gold standard randomized controlled trials examining the efficacy and impact of the WeightWatchers program. The body of evidence is clear: WeightWatchers is an effective, scalable, and cost-effective program with sustained weight loss and wellness outcomes.
The research doesn’t stop here though: we’re committed to continuing to work with the scientific community to advance the scientific literature and stay up to date on the latest in weight management-related science.
