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.

Conditions

  • Overweight and Obesity

Interventions

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.
