Adherence
Individualized Medical Nutrition Therapy (MNT) provided by a Registered Dietitian Nutritionist (RDN) significantly improves glycemic control (A1C reduction up to 2.0% in T2D and 1.9% in T1D) and is cost-effective, making it a fundamental component of diabetes management.
Ask your doctor for a referral to a Registered Dietitian Nutritionist (RDN) who specializes in diabetes. Expect about 3-6 visits in the first six months to build your personalized plan, followed by at least one check-in per year. This is covered by Medicare and many insurers. The goal is to lower your A1C and manage weight through sustainable changes tailored to your culture and preferences, not a rigid diet.
Strong evidence supports the effectiveness of MNT interventions provided by RDNs for improving A1C, with absolute decreases up to 2.0% (in type 2 diabetes) and up to 1.9% (in type 1 diabetes) at 3–6 months. Ongoing MNT support is helpful in maintaining glycemic improvements.

- Intensive lifestyle interventions modeled on the Diabetes Prevention Program (DPP), including individualized MNT and physical activity, reduce the incidence of type 2 diabetes by 58% in adults with prediabetes and overweight/obesity.Strong
- Reducing overall carbohydrate intake, particularly to very low-carbohydrate levels (<26% of calories), demonstrates the most evidence for improving glycemia (A1C) and reducing medication needs in adults with type 2 diabetes, especially in the short term (3-6 months).Good
