An interventional study of SWITCH Diets - Mobile Nutrition Behavioral Intervention in Obesity Type 2 Diabetes Mellitus and Obesity, sponsored by University of South Carolina. Recruiting at 1 site in United States. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-09-23.
Sponsored by University of South Carolina · Not applicable, Interventional, and Other
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.
Age between 18 and 65 years.
Exclusion Criteria:
Presence of type 1 diabetes mellitus
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.
Intervention acceptability, usefulness and ease of use
Acceptability, satisfaction, and perceived burden of the intervention, assessed using the Treatment Acceptability and Preferences (TAP) measure(0-10 scale; 0 = not at all, 10 = extremely), with 0-3 indicating low and 7-10 high levels (higher burden = less favorable). Perceived usefulness, ease of use, and intention to use digital tools, assessed using the Technology Acceptance Model (TAM) survey (1-5 Likert scale; 1 = strongly disagree, 5 = strongly agree), with 1.0-2.4 indicating low and 3.5-5.0 high levels.
Time frame: End of 6-week intervention
Change in Healthy Eating Index
The Healthy Eating Index (HEI) is a scoring metric developed by the U.S. Department of Agriculture (USDA) and the NCI to assess how well a person's diet conforms to the Dietary Guidelines for Americans. It evaluates the consumption of 13 dietary components, including both adequacy (foods to increase) and moderation (foods to decrease). The scores range from 0 to 100. An ideal overall HEI score of 100 reflects that the set of foods aligns with key dietary recommendations and dietary patterns published in the Dietary Guidelines.
Time frame: Baseline to end of 6-week intervention
