The WW Unlimited Workshops and Digital Program is an evidence-based behavioral weight management program that guides members toward personal weight and wellness goals through a personalized curriculum, complemented with behavioral weekly goals to drive healthy habits. The program includes foods that can be eaten in moderation without the need to tracking, as well as a points system that rates foods. In addition, members have access to food, activity, water, sleep, and weight trackers, meal planning tools, recipes, guided meditations and workouts, peer support, and access to online workshops and WW-trained behavior change coach.~To compare the 6-month changes in diet quality (HEI-2015 total score), in adult participants enrolled in a commercial weight-loss program (WW) vs. control, a total of 376 adults will be recruited via social media and other online platforms in the contiguous 48 States of the US. Participants will be randomly assigned to access the WW app, or a control, and will be followed-up for 6 months.
The main objective of this study is to determine whether a behavior change weight management and wellness program (WW) delivered via an app for 6-months will be effective in improving diet quality in U.S. adult participants, relative to a control group through a randomized controlled trial.
