Dietary Insights and Nutritional Education in Adults on GLP-1 Therapy

Purpose

This pilot study will evaluate the feasibility, acceptability, and perceived usefulness of the SWITCH mobile nutrition behavioral intervention among adults receiving GLP-1 receptor agonist therapy for obesity and/or type 2 diabetes. Participants will complete baseline assessments, receive a 6-week app-based nutrition intervention consisting of daily dietary self-monitoring and weekly learning modules, and complete follow-up assessments and a structured interview.

SWITCH Intervention
  • Behavioral: SWITCH Diets - Mobile Nutrition Behavioral Intervention
    SWITCH Diets is a mobile health nutrition intervention adapted for adults receiving GLP-1 therapy. Participants track food intake daily in the app and receive tailored goals for fiber, potassium, magnesium, and protein, based on baseline characteristics. The app provides visual feedback on progress toward nutrient goals and weekly learning modules with diet-related education, audio/video content, recipes, and quizzes.
