Trial Summary

What is the purpose of this trial?Self-monitoring (of weight, intake, and activity) is a core component in evidence-based lifestyle interventions for obesity. Research has shown that interventionist feedback increases adherence to self-monitoring and improves weight loss outcomes; however, little empirical evidence exists on how this feedback should be provided. This research study aims to optimize the provision of self-monitoring feedback.

Eligibility Criteria

This trial is for individuals looking to manage obesity through weight loss. Participants should be committed to self-monitoring their diet, physical activity, and weight. Specific eligibility criteria are not provided, but typically include being over a certain age and having a body mass index (BMI) that classifies as obese.

Participant Groups

The study tests how different components like diet quality, goal setting, calorie goals, and physical activity affect the success of self-monitoring in treating obesity. It aims to find the best way to provide feedback that encourages adherence to these components.
