Carbohydrate counting or "carb counting" is a meal planning technique for persons with diabetes for managing blood glucose levels by tracking the grams of carbohydrate consumed at meals. It has shown to improve glycaemic control and glycaemic variability and decreases risk of hypoglycaemia in persons with diabetes especially on insulins. ⋯ It also gives flexibility of food choice, helps to identify patterns in blood glucose levels and adjustment of pre meals short acting insulins as related to food intake. In this short review we have summarised basic principles of carbohydrate counting, its application in clinical practice and also exchange lists primarily pertaining to South Asian population.
