Summary

This is a single-arm feasibility trial to examine an mHealth intervention that combines high fiber education, home-delivered high fiber foods, and use of continuous glucose monitors.

Detailed description

This is a single-arm trial enrolling young adults (aged 18-39) with prediabetes (based on hemoglobin A1c). Enrolled individuals will complete baseline data collection in person to assess insulin resistance (venous blood samples). Enrolled individuals will then complete a three-month fully-mHealth based intervention focused exclusively on promoting greater fiber intake. Participants will receive weekly home-delivered shipments of high fiber foods and wear a continuous glucose monitor at two time points as a form of biofeedback. After the three months, participants will return for repeat assessment of insulin resistance. After that repeat assessment, participants will do a one-month observation period using cell phone-based ecological momentary assessments.
