Participants will receive an evidence-based behavioral weight control program focused on physical activity and reducing caloric intake. They will be provided with a Fitbit Zip and digital body weight scale for self-monitoring of physical activity and body weight, respectively. They will track caloric intake via the MyFitnessPal smartphone application. They will have access to a study website and attend weekly, in-person group counseling sessions.
Participants will receive the same intervention components as the Standard group, as well as two extra Fitbit Zips and digital body weight scales to share with up to two persons in their social circle who will be invited to serve as their support partners.
