1. l Definition and Reasons Behind Popularity Definition • Carbohydrate Counting is a meal planning approach based on the following ideas 1 : • Carbohydrates is the main nutrient affecting post-prandial glycemic • l response Total amount of carbohydrates is more important than source of carbohydrates Reasons behind popularity • Effectiveness 2 • Flexibility 3 • Ease of implementation 4 1.
