Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Research suggests that when one spouse loses weight, the other spouse does too. This study will examine whether a ripple effect is observed in untreated spouses and children of individuals participating in a nationally available weight loss program. Participants will be randomly assigned to either receive Weight Watchers immediately or at the end of a 6-month waiting period. Participants and untreated spouses (and any children in the home) will be assessed at baseline, 3, and 6 months.
