Adherence
Individualized medical nutrition therapy (MNT) by a registered dietitian reduces hemoglobin A1c by 1-2% in type 2 diabetes, with the greatest benefit seen in newly diagnosed patients.
Work with a registered dietitian to create a personalized eating plan rather than following a generic 'diabetes diet.' Focus on nutrient-dense foods, portion control, and matching your food intake to your medication (if on insulin). Consistency and professional support are more important than adhering to a specific macronutrient ratio.
Nutrition therapy interventions implemented by registered dietitians/nutritionists reduced HbA1c levels by an average of 1% to 2% (range -0.23% to -2.6%) depending on the type and duration of diabetes and the HbA1c level at implementation.
