How does weight management influence glucose regulation in type 2 diabetes?

• A. Weight loss improves insulin sensitivity and can reduce medication requirements and improve glycemic control
• B. Weight loss has no effect
• C. Weight gain improves glycemic control
• D. Weight loss worsens glycemic control

Answer: (A)

Weight management is a major lever in how glucose is regulated in type 2 diabetes. Losing excess weight, especially visceral fat, makes the body's tissues more responsive to insulin. When insulin sensitivity improves, glucose is taken up into muscle and fat more effectively, and the liver reduces its production of glucose. This combination lowers blood sugar levels and can allow for lower medication doses or even improved glycemic control without increasing medications. Even modest weight loss—around 5–10% of body weight—can yield meaningful improvements in insulin sensitivity and glucose control. On the flip side, gaining weight tends to worsen insulin resistance and make blood sugar harder to manage. So maintaining a healthy weight supports better glucose regulation in type 2 diabetes.
