If insulin is used, which insulin type is recommended to minimize weight gain?

• A. Basal insulin
• B. Rapid-acting insulin
• C. Mixed insulin
• D. Inhaled insulin

Answer: (A)

Managing weight gain on insulin hinges on the dosing pattern: basal versus bolus coverage. Basal insulin provides a steady background level that mainly controls fasting glucose and requires less mealtime dosing. Because it reduces the need for large bolus doses around meals, the total insulin exposure tends to be smaller than regimens that rely heavily on rapid-acting or mixed insulins to cover eating. Since insulin promotes energy storage and reduces glucose loss in urine, more total insulin — especially from meal-time boluses — typically leads to more weight gain. Inhaled insulin is a rapid-acting, meal-time option and adds to total bolus insulin, which can also contribute to weight gain. Therefore, the most weight-gain-minimizing approach among these options is basal insulin.
