About this trial
The goal of this study is to test multiple individual treatment components added to a 6-month standard mobile behavioral weight loss program that are intended to help participants follow dietary recommendations and meet their dietary goals more often. The four components to be studied include switching dietary tracking methods, receiving access to a goal planning tool, receiving additional personalized text messages, and receiving three sessions with a health coach. The study will identify the best combination of these additional treatments for improving total number of weeks in the program that participants meet their dietary goals.
