Trial Summary

What is the purpose of this trial?

The goal of the Self-monitoring With Internet Technology to Choose Healthy Diets (SWITCH) study is to examine a 12-week remotely delivered program designed to help adults adopt a healthy dietary lifestyle and lose weight in a diverse cohort of adults with overweight/obesity. The intervention uses a self-determination theory framework to provide a deeper understanding of the factors that influence dietary behavior within the context of tracking. This study incorporates autonomy-supportive strategies to encourage participants to feel more in control of their dietary choices and will provide information and resources to boost participant's competence in achieving their dietary goals. The intervention includes weekly learning modules to support healthy eating and weight loss and daily dietary tracking with visual feedback, all accessible within the SWITCH app.
