Using an AI Mobile Application to Promote Healthy Eating
United States114 participantsStarted 2026-10
Plain-language summary
The goal of this feasibility study is to determine the adherence, acceptability, and usability of the behavioral intervention of a mobile AI application and its effects on food choices and diet quality. A secondary goal is to assess whether the app's accuracy or feasibility differs by food security status. Study participants are UC Davis students aged 18-24 years. The main question it aims to answer is:
\- Does the gamified app version that delivers behavioral nudges have a higher adherence and acceptability rate, and does this translate to better dietary behaviors?
Participants will use either the intervention app (dietary assessment + gamification) or the control app (non-gamified, dietary assessment only) for six weeks to record all their food intake. Diet quality will be assessed at baseline and endline, and a Likert scale acceptability questionnaire will be administered at endline.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial is studying a mobile app to promote healthy eating in people who are already healthy — given that I'm not being treated for a specific condition, is participating in a study like this something that makes sense for my situation, or would my time be better spent elsewhere?
2The trial is measuring how acceptable, easy to use, and consistently people stick with the app — does that mean this is still in early testing stages where researchers are mainly trying to figure out whether the app works well as a tool, rather than proving it actually improves health outcomes?
3Since the trial hasn't started recruiting yet, do you have a sense of when it might open, and is there anything I should be doing in the meantime to work on healthy eating through established programs you'd recommend?
4The study assigns participants to different versions of the app — can you help me understand what that means for me practically, like whether I might receive a version with fewer AI features, and how that could affect what I get out of participating?
5Are there any concerns about sharing my dietary or personal health data through an AI-based app as part of a research study, and what questions should I be asking the research team about privacy and data use before I sign up?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
