Clinical Trial Summary

The aim of this study is to compare brain changes in individuals with overweight or obesity enrolled in either the Noom Healthy Weight program or a matched control. The study objectives (primary and secondary) are to measure brain change reported as ERP and EEG data over a 16-week timeframe. Additionally, we will explore changes in the default mode network (resting-state asymmetry in EEG measurements), changes in executive functioning, quality of life, mood, and salivary markers as they relate to EEG data.

Intervention

Behavioral:
• Noom Healthy Weight; mobile behavior change program for weight loss.
The mobile cognitive behavior change program follows guidelines from the Obesity Society's "2013 Guidelines for the Management of Overweight and Obesity in Adults" NIH "Practical Guide on the Identification, Evaluation, and Treatment of Overweight and Obesity in Adults". There are 52 weeks of curriculum with 1-3 articles to read per day. Users are requested to perform weight logging once daily and food logging after each meal. Users are assigned human coaches and are able to interact with them via in-app messaging or phone communication. Users are also assigned to support groups via in-app messaging.

Other:
• Matched Control
Matched control group (Noom-branded 'healthy eating' short guide on weight loss).
