High-fiber mHealth program for young adults with prediabetes
Official title: Preliminary Examination of an Innovative mHealth-Based Dietary Fiber Intervention to Improve Outcomes in Young Adults With Prediabetes: A Feasibility Study
Run by University of Oklahoma · NCT07491653 · Data updated 2026-11-12
This three-month phone-based program tests whether weekly home-delivered high-fiber foods, brief education, and continuous glucose monitor feedback can improve blood sugar control in young adults (18–39) with prediabetes.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are English-speaking young adults (18–39) living near the Tulsa metro with prediabetes by HbA1c, who can use a compatible smartphone and are not pregnant, breastfeeding, on GLP-1 agonists, or have eating disorders or disqualifying food allergies.
✕Probably not a fit
People with established diabetes, those pregnant or breastfeeding, individuals on GLP-1 receptor agonists, those with serious eating disorders or food restrictions, or anyone unable to use a smartphone or attend Tulsa visits are unlikely to benefit from this intervention.

What this trial studies
This single-arm feasibility trial enrolls adults aged 18–39 with prediabetes and collects baseline venous blood to measure insulin resistance. Participants complete a three-month fully mHealth intervention that provides high-fiber nutrition education, weekly home deliveries of high-fiber foods, and periodic continuous glucose monitor (CGM) use for biofeedback. After the intervention participants return for repeat blood testing of insulin resistance and then complete a one-month observation period with smartphone-based ecological momentary assessments. Outcomes focus on feasibility, changes in glycemic markers and insulin resistance, and real-world adherence to higher-fiber eating.
Why it matters
Potential benefit: If successful, the approach could help lower blood sugar and improve insulin resistance through practical dietary changes delivered and reinforced via smartphones and CGM feedback.
How similar studies have gone: Separate research supports that higher dietary fiber and mHealth or CGM-based feedback can improve glycemic control, but combining home food delivery with CGM-based biofeedback in young adults with prediabetes is relatively novel.
