What research says about WW
Since its foundation in 1963, WW has always been rooted in science. Our dedicated Science team uses credible, established research to inform our consistently-evolving program, and works closely with the scientific community to ensure we meet the highest standards.
Over the past four decades, more than 125 studies (including over 25 gold standard randomized trials) have examined the efficacy and impact of the WW program. The body evidence is clear: WW is an efficacious, scalable, and cost-effective program with sustained weight loss and wellness outcomes.
Below, find a comprehensive list of published, peer-reviewed scientific articles evaluating WW.
