From the Guidelines

Type 2 diabetics should consider carbohydrate counting as part of their diabetes management, as it helps maintain blood glucose levels by matching food intake with medication and activity levels, with a focus on reducing overall carbohydrate intake to improve glycemia, as recommended by the most recent guidelines 1.

Importance of Carbohydrate Counting

Carbohydrate counting is essential for type 2 diabetics, especially those taking mealtime insulin, as it allows for the calculation of appropriate insulin doses using their prescribed insulin-to-carb ratio. Even type 2 diabetics not on insulin benefit from carb awareness, aiming for consistent carbohydrate intake at meals.

Key Recommendations

  • Emphasize minimally processed, nutrient-dense, high-fiber sources of carbohydrate (at least 14 g fiber per 1,000 kcal) 1.
  • Replace sugar-sweetened beverages with water or low-calorie beverages to manage glycemia and reduce cardiometabolic disease risk 1.
  • Provide education on the glycemic impact of carbohydrate, fat, and protein tailored to an individual’s needs, insulin plan, and preferences to optimize mealtime insulin dosing 1.

Benefits of Carbohydrate Counting

  • Improves glycemic control
  • Reduces risk of hypoglycemia
  • Allows for personalized meal planning based on individual medication regimens, activity levels, and health goals
  • Supports weight management and overall health outcomes

Tools for Accurate Counting

  • Measuring cups
  • Food scales
  • Smartphone apps
  • Working with a registered dietitian to develop a personalized carbohydrate plan By following these guidelines and recommendations, type 2 diabetics can effectively manage their carbohydrate intake and improve their overall health outcomes, as supported by the most recent and highest quality study 1.

From the Research

Carbohydrate Counting for Type 2 Diabetics

  • Carbohydrate counting is a meal planning technique that can help individuals with diabetes, including type 2 diabetics, manage their blood glucose levels by tracking the grams of carbohydrate consumed at meals 2, 3.
  • This approach can be beneficial for people with all types of diabetes, including type 2 diabetes, as it can help improve glycaemic control and quality of life 2.
  • There are different levels of carbohydrate counting, ranging from basic to advanced, which can be tailored to individual needs and goals 3.
  • Research has shown that carbohydrate counting can be an effective approach for managing type 2 diabetes, and can be used in conjunction with other treatments, such as medication and lifestyle changes 4.

Benefits of Carbohydrate Counting for Type 2 Diabetics

  • Carbohydrate counting can help individuals with type 2 diabetes improve their glycaemic control and reduce their risk of complications 3, 4.
  • This approach can also help individuals with type 2 diabetes develop healthier eating habits and improve their overall quality of life 2, 3.
  • Carbohydrate counting can be tailored to individual needs and goals, and can be used in conjunction with other treatments, such as medication and lifestyle changes 3, 4.

Studies on Carbohydrate Counting for Type 2 Diabetics

  • A randomized, controlled trial found that basic carbohydrate counting as an add-on to standard dietary care led to improved skills in estimating carbohydrate intake among individuals with type 2 diabetes, although no significant differences in glycaemic control were found 4.
  • Another study discussed the use of carbohydrate counting as a meal planning approach for individuals with diabetes, including those with type 2 diabetes, and highlighted its potential benefits for improving glycaemic control and quality of life 3.
