The nurse counsels the 30-year-old woman with type 2 diabetes who is overweight and noncompliant that control of diabetes would most improve if she were to:

A. Eat a high-protein diet: A high-protein diet is not specifically recommended for improving blood glucose control in type 2 diabetes. A balanced diet with a focus on carbohydrates, fiber, and portion control is more effective for long-term management. B. Lose weight: Weight loss is one of the most effective ways to improve blood sugar control in type 2 diabetes. It reduces insulin resistance, enhances insulin sensitivity, and leads to better overall glucose management. C. Take insulin: Insulin is typically not the first treatment for type 2 diabetes, especially in individuals who are overweight. Lifestyle changes, including diet and exercise, are generally prioritized before moving to insulin therapy. D. Take more metformin (Glucophage): While metformin is an important medication, weight loss through lifestyle modifications often has a more significant and lasting impact on blood sugar control than simply increasing the dosage of medication.
