What is the purpose of carbohydrate counting in insulin therapy?

The purpose of carbohydrate counting in insulin therapy is to calculate the amount of insulin needed based on carbohydrate consumption. This practice is essential for individuals with diabetes, as carbohydrates are the macronutrient that most significantly affects blood glucose levels. By understanding how many grams of carbohydrates are consumed, a person can adjust their insulin dosage accordingly to maintain glucose levels within the target range.

For example, if a person knows they consume a specific number of carbohydrates at a meal, they can use a predetermined insulin-to-carb ratio to determine how much insulin to administer. This tailored approach improves glucose management, reduces the risk of hyperglycemia (high blood sugar), and enhances overall diabetes control.

The other choices relate to different aspects of diabetes management but do not directly associate with the primary goal of carbohydrate counting in insulin therapy. Protein intake, overall calorie monitoring, and physical activity levels contribute to an individual's health and diabetes management but are not the central focus of carbohydrate counting.
