Brief Summary
The goal of this project is to investigate how to enhance the effects of an online-only (mHealth) couples weight loss program. This study will use an innovative methodological framework, the Multiphase Optimization Strategy (MOST), to test four different strategies for weight loss and partner support in addition to a core intervention (i.e., dyadic action planning, joint feedback on goal progress, autonomy support training, and home environment modifications).

Interventions
Behavioral weight loss core (lessons, self weighing, self-monitoring, individual action planning, feedback and progress check ins)
Participants will develop dyadic action plans together.
Participants will see data on their partner's progress, in addition to their own weight and behavioral data.
Participants will receive training in how to create an autonomy supportive environment within their marriage/partnership.
Participants will be trained in how to structure their home environment to support health behavior.
