Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary goal of this project is to determine if an innovative behavioral weight loss program that incorporates new developments from the field of behavior therapy produces superior weight control than standard behavioral treatment. A sample of 200 adults from the community are participating in this study.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Be between the ages of 18 and 70
* Have a BMI between 27-50

* Agree to provide permission for the research team to regularly contact your physician throughout the study to share information on changes in your weight.
* Successfully complete all steps in the enrollment process

Exclusion Criteria

* You have a medical condition or psychiatric condition that may limit your ability to comply with the behavioral recommendations of the program or pose a risk to you during weight loss.
* You are pregnant or plan to become pregnant in the next three years.
* Report recently beginning a course of or changing the dosage of prescription medications that can cause significant weight loss or weight gain.
* You are participating in or plan to participate in another weight loss program in the next three years.
* The research team identifies any factors that would render you potentially unable or unlikely to follow the protocol, or unable to benefit from it.
