---

110 participants in 2 patient groups

Standard

Active Comparator group

Description:

A 12-week internet-based weight loss program that involves weekly video lessons, a self-monitoring platform where participants submit their weight, calorie, and activity information, and weekly automated feedback.

Treatment:

Behavioral: Standard

Early intervention

Experimental group

Description:

Participants randomized to Early Intervention will receive the same internet-based weight loss program compared to the Standard group. In addition, Early Intervention participants achieving less than optimal weight loss following several weeks of treatment will be given the opportunity to come to the Weight Control and Diabetes Research Center for an individual visit. At this visit, an interventionist will discuss with the participant any barriers that he or she may be experiencing and recommend alternate strategies to assist in their weight loss. One such strategy would be to recommend the use of meal replacement products or portion controlled meals. In addition to this one-time visit, the interventionist will follow up with the participant via phone weekly, for 2 weeks following this in-person visit.

Treatment:

Behavioral: Early Intervention
