Brief Summary

This study is a 3-group, parallel design, randomized controlled trial (RCT) in 105 adults with obesity and food insecurity that will compare BWL-Alone (including standard-of-care referral and connection with community food resources; n=35) to BWL plus food supplementation with either food vouchers (BWL+VOUCHER; n=35) or home-delivered, medically tailored groceries consistent with BWL recommendations (BWL+HOME; n=35). All groups will have BWL treatment provided for 24 weeks per clinical guidelines. Food vouchers and HOME will be provided for 24 weeks of treatment. Assessments will be conducted at baseline, and weeks 12 and 24.

This group will receive the BWL program as well as home-delivered boxes of groceries of low-energy density foods conducive to weight management guidelines. Groceries will include shelf-stable and perishable products like lean meats, fresh vegetables, and fruits. Every 2 weeks, participants assigned to this group will be allowed to select a choice of one of 4 boxes with slightly varied contents. Each box will have approximately $40 worth of groceries.

BWL+HOME

The behavioral weight loss program consists of 14 individual lifestyle counseling sessions provided over 24 weeks. Each session will be approximately 15-20 minutes. Visits will be scheduled weekly for the first 4 weeks (weeks 1, 2, 3, and 4) and every-other week from weeks 6-24 (weeks 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24).
