Participants will enroll in the BWLI program for 12 months. BWLI consists of a 8-month initial intervention phase followed by 4-month maintenance phase. The initial intervention phase comprises four types of contact:

• 1-hour to 1-hour, 30 minute group weight-management class led by facilitator (once per week; 26 classes followed by a one week break and an additional 8 weight management review classes)
• 45 minute, physical activity led by facilitator (one-two times per week);
• 20 minute, monthly individual visit with facilitator to address barriers to goals and appropriate skills; and
• weigh-in during weight management group and individual visits (once each week).

Participants randomly assigned to this condition will begin simultaneously with BWLI and run concurrently across the eight months of the intervention. Peer navigators will meet individually and face-to-face with research participants in time and places convenient to the person as needed. Specific practices are determined by the research participant with the peer navigator and may include:

• partnering with participant on BWLI homework;
• meeting with participant and BWLI facilitator individually;
• attending all other health care appointments; and
• partnering on tasks that arise out of those appointments.

Participants in this arm will receive integrated care from their usual provider, which is treatment as usual. Integrated care is mental health specialty and general medical care providers working together to address the physical and behavioral health care needs of patients. One-third of research participants will be randomized to integrated care alone.
