Mediterranean diet adherence in people with type 1 diabetes starting the MiniMed 780G

Official title: Adherence to Mediterranean Diet in Type 1 Diabetes Initiating Minimed 780G: Glucose Metrics vs Insulin Metrics, is There a Difference

Run by Attikon Hospital · NCT06646107 · Data updated 2026-11-12

We will test whether sticking to a Mediterranean diet changes CGM and insulin metrics in people with type 1 diabetes who are starting the MiniMed 780G system.

Is this trial a fit for you?

Likely a good fit

People with type 1 diabetes who are on multiple daily injections or an insulin pump, are planning to start the MiniMed 780G system, and meet clinical entry criteria (for example HbA1c <12.5% and clinically able to start AHCL) are ideal candidates.

Probably not a fit

Patients who are not starting the MiniMed 780G, who had diabetic ketoacidosis within the prior six months, or who cannot attend regional in-person visits are unlikely to gain direct benefit from this project.

What this trial studies

This observational project will enroll 240 children, adolescents and young adults with type 1 diabetes across Italy, Greece and Israel who are scheduled to begin the MiniMed 780G system. After a 7-day run-in participants complete a 7-day food diary and the PREDIMED questionnaire, receive a one-hour Mediterranean diet counseling session, then start the 780G and are followed for 12 weeks with baseline and 12-week measurements. Key outcomes include HbA1c, CGM and insulin metrics, anthropometrics, body composition, blood pressure, lipids and gut microbiome, while endothelial and cardiovascular markers will be measured at baseline, 6 and 12 months with an optional extension to one year. The analysis compares diet adherence before and after device initiation and relates adherence scores to glucose control and insulin use metrics.

Why it matters

Potential benefit: If successful, the results could help patients and clinicians know whether following a Mediterranean diet improves glucose control or insulin needs after starting the MiniMed 780G.

How similar studies have gone: Previous studies show automated insulin delivery systems like the MiniMed 780G improve CGM metrics and Mediterranean-style diets are linked to better cardiometabolic markers, but combining diet adherence with AHCL outcomes is relatively novel.
