Summary

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.

Detailed description

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.

Interventions

Type	Name	Description
BEHAVIORAL	WW	WW assigns foods to a point value calculated through a proprietary algorithm that accounts for the food's caloric value, saturated and unsaturated fat, sugar, fiber, and protein. Members are encouraged to track their food and beverage intake, with the goal of staying within their personal points targets assigned based in an individual's sex, age height, weight, goals, and activity. The program also has "Zero Point Foods" (list of healthy foods with no point value) and can be eaten freely. In addition to the personal points, participants will be asked to attend WW coach-led virtual workshops conducted over Zoom, engage with peer- support, and WW-trained behavior change experts via 24/7 chat.
