Currently, carb counting is a nutritional strategy that has allowed a greater adherence and dietary management of patients with diabetes mellitus, because it allows the consumption of a greater variety of foods. However, also requires greater adherence by the patient to maintain an adequate blood glucose monitoring and the ability to determine the amount of carbohydrates in the meals. Since diabetes mellitus is a chronic disease, a more flexible and varied diet will allow better monitoring, taking into account their glycemic control in long-term. The objective of this study was to examine the applicability of this method to a less restrictive diet and nutritionally adequate for the patient with diabetes mellitus, as well an individual dietary adjustment that is needed to better glycemic control, identifying nutritional advantages and disadvantages of the method.
