What this research studies

If you join, you would enroll as a Veteran together with a romantic or non-romantic person you live with who also participates. You will be randomly assigned to either the usual VA weight-management program or to a version where you and your support person are taught communication and support skills to help maintain diet and activity changes. The study team will measure weight, adherence, and other outcomes over time and use virtual and primary care–linked visits to deliver the intervention. The goal is to see whether involving a household support person helps Veterans sustain weight loss better than standard care.

Who could benefit from this research

Good fit: Ideal candidates are Veterans age 21 or older with obesity who live with and can enroll a romantic or non-romantic support person willing to participate.

Not a fit: People who do not live with a supportive cohabiting person or who cannot engage a partner to join the program are unlikely to benefit from this specific approach.

Why it matters

Potential benefit: If successful, this approach could help Veterans keep weight off longer and reduce the risk of diabetes, heart disease, and other obesity-related conditions.

How similar studies have performed: Existing VA programs like MOVE! produce short-term weight loss but often see regain, and adding household support is a promising but not yet proven method for improving long-term maintenance.
