What is carbohydrate counting?
Carbohydrate counting is a way to plan your meals by counting the amount of carbohydrate in foods. Carbohydrates are the sugars, starches, and fiber found in fruit, grains, vegetables, and milk products. Carbohydrates increase your blood sugar levels. Carbohydrate counting can help you eat the right amount of carbohydrate to keep your blood sugar levels under control.
What do I need to know about planning meals using carbohydrate counting?
- A carbohydrate serving contains about 15 grams (g) of carbohydrate. A dietitian or healthcare provider will tell you how many carbohydrate servings you should have for each meal and snack. The number of servings will be based on your age, weight, usual food intake, and physical activity level. It will also be based on your blood sugar levels and diabetes medicine.
- Check your serving sizes using measuring cups or a food scale. Also read nutrition labels to find out how much carbohydrate is in the foods you eat. See "Total Amount of Carbohydrate" on the label for the amount. The amount of carbohydrate in the serving size listed on the package may be more than 15 g. Keep track of the amount of carbohydrate servings you have for each meal and snack. The number of carbohydrate servings you have may need to be adjusted based on your blood sugar levels. Do not avoid carbohydrates or skip meals. Your blood sugar may fall too low if you do not eat enough carbohydrate or you skip meals.

How do I use carbohydrate counting to plan meals?
- Count carbohydrate amounts using serving sizes:
- Pasta dinner example: You plan to have pasta, tossed salad, and an 8-ounce glass of milk. Your healthcare provider tells you that you may have 4 carbohydrate servings for dinner. One carbohydrate serving of pasta is ⅓ cup. One cup of pasta will equal 3 carbohydrate servings. An 8-ounce glass of milk will count as 1 carbohydrate serving. These amounts of food would equal 4 carbohydrate servings. One cup of tossed salad does not count toward your carbohydrate servings.
- Count carbohydrate amounts using food labels: Find the total amount of carbohydrate in a packaged food by reading the food label. Food labels tell you the serving size of the food and the total carbohydrate amount in each serving. Find the serving size on the food label and then decide how many servings you will eat. Multiply the number of servings you plan to eat by the carbohydrate amount per serving.
- Granola bar snack example: Your meal plan allows you to have 2 carbohydrate servings (30 grams) of carbohydrate for a snack. You plan to eat 1 package of granola bars, which contains 2 bars. According to the food label, the serving size of food in this package is 1 bar. Each serving (1 bar) contains 25 grams of carbohydrate. The total amount of carbohydrate in this package of granola bars would be 50 g. Based on your meal plan, you should eat only 1 bar.
