Who could benefit from this research
✓Could help
Adults (21+) with type 2 diabetes and a baseline hemoglobin A1c of about 6.8–8.5% who are willing to wear a CGM and attend nutrition counseling sessions are ideal candidates.
✕Less likely to help
People with type 1 diabetes, those with A1c outside the study range, pregnant individuals, or anyone unwilling/unable to use a CGM or attend visits are unlikely to benefit from or qualify for this trial.
What this research studies
You would wear a continuous glucose monitor (CGM) and either receive personalized medical nutrition therapy based on your real-time glucose patterns or not, depending on the group you are randomized into. The 12-week trial enrolls 72 adults with type 2 diabetes and baseline A1c between 6.8% and 8.5%, split into four groups combining blinded or unblinded CGM with or without nutrition counseling. Study staff will review CGM data to provide individualized meal guidance for those in the nutrition therapy arms, while others will wear CGMs without tailored counseling. The team will compare changes in A1c, glucose variability, and diabetes self-efficacy across the groups.
Why it matters
Potential benefit: If successful, this approach could improve blood sugar control, reduce glucose swings, and help people feel more confident managing their diabetes through personalized meal plans.
How similar studies have gone: Previous studies show CGM use in lifestyle programs can lower A1c and improve diabetes self-efficacy, but using CGM data specifically to personalize medical nutrition therapy is a relatively new approach with limited large trial evidence.
