Primary outcomePrimary: Change in Weight From Baseline — 210.1; 211.7; 199.4; 204.6 lbs
Summary
The goals of the study are to use the Noom mobile app to help individuals with weight loss and weight loss maintenance. This project will test the comparative efficacy of Noom Health vs. Noom Digital Health for weight loss, quality of life, psychosocial functioning, and self-reported health status. It is expected that use of Noom Health will show post-intervention success relative to Noom Digital Health as well as long-term success with weight loss maintenance. Data is expected to show that participants who are older, have less support, have more health conditions, and with more psychosocial problems will benefit more from Noom Health. It is also expected that confidence in the ability to lose weight will produce more successful results in Noom Health vs. Noom Digital Health.
