Summary

This study tests whether a virtual weight management program that includes a support person (like a family member or friend) helps Veterans with obesity lose weight. 320 Veterans and their partners will participate in 8 virtual sessions over 14 weeks. The main goal is to see if this approach leads to weight loss and healthier habits compared to standard care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
HealthyTogether behavioral intervention
What this could lead to
If it works, this could provide an effective, scalable weight management option for Veterans that leverages social support.
What could go wrong
This is a relatively small, early-stage behavioral trial. Results may not generalize to non-Veterans, and weight loss may be modest or not sustained long-term.
