Carbohydrates, commonly known as carbs, are naturally present in various foods, including grains, sweets, starches, legumes, and dairy products. When we consume foods and drinks containing carbs, our body breaks them down into glucose, which fuels our cells and raises blood glucose levels. For individuals without diabetes, the body's insulin response effectively manages these blood glucose spikes. However, for those with diabetes, insulin either doesn't function correctly or isn't produced in sufficient amounts, making it challenging to regulate blood glucose levels.
Learning about carbohydrate counting can be a valuable tool for managing blood glucose levels, especially when combined with an appropriate treatment plan. The consistent carbohydrate diet (CCHO), also known as the constant carbohydrate or controlled carbohydrate diet, focuses on consuming the same amount of carbohydrates each day to help stabilize blood sugar levels.
Understanding Carbohydrates and Their Impact on Blood Sugar
There are three primary types of carbohydrates found in food: starches, sugar, and fiber. The term "total carbohydrate" on nutrition labels encompasses all three. The goal is to prioritize nutrient-dense carbs, which are rich in fiber, vitamins, and minerals, while being low in added sugars, sodium, and unhealthy fats.
Types of Carbohydrates
Sugars: These are simple carbohydrates that are quickly broken down by the digestive system. Some sugars occur naturally, such as fructose in fruit, while others are processed, like white table sugar.
Starches: These are complex carbohydrates that digest more slowly. Examples include lima beans, potatoes, and whole grains.

Fiber: Also a complex carbohydrate, fiber is found in foods like apples, celery, and chickpeas.
Carb Counting: A Tool for Diabetes Management
Carb counting involves tracking the number of grams of carbohydrates in meals and snacks to match them with the appropriate insulin dosage, if applicable.
Carb Counting for Type 1 Diabetes
If you have type 1 diabetes, your pancreas no longer produces insulin. Therefore, you must take insulin to manage blood glucose fluctuations caused by the food you eat. Carb counting becomes essential to determine the correct insulin dosage based on the carbohydrate content of your meals and snacks.
Carb Counting for Type 2 Diabetes
If you have type 2 diabetes, you may experience insulin resistance, where your body doesn't respond effectively to the insulin it produces, or you may not produce enough insulin to maintain target blood glucose levels. Monitoring your carb intake is crucial. Eating a consistent amount of carbs at meals and snacks throughout the day can help avoid high blood glucose levels.
Methods of Carb Counting
Advanced Carb Counting: This method is typically recommended for individuals on intensive insulin therapy, such as those with type 1 diabetes or some with type 2 diabetes. It involves calculating the precise number of carbohydrate grams in each meal and dosing mealtime insulin accordingly, using an insulin-to-carb ratio.

Basic Carb Counting: Individuals with type 2 diabetes who don't take mealtime insulin may opt for a simpler approach, focusing on "carbohydrate choices," where one choice equals approximately 15 grams of carbs.
Diabetes Plate Method: This method involves dividing a plate into sections, with a quarter of the plate allocated to whole grains, starchy vegetables, fruits, or dairy.
Determining Your Ideal Carb Intake
There is no universal "magic number" for the ideal number of carbs per meal. Individual carbohydrate needs are determined by factors such as body size, activity level, appetite, and hunger. Consulting with a registered dietitian nutritionist (RDN/RD) or Certified Diabetes Care and Education Specialist (CDCES) is recommended to create a personalized eating plan.
Finding a Diabetes Education Program
Tracking your food intake and blood sugar levels before and after meals for a few days can provide valuable insights into how different meals impact your blood glucose. This information can help you and your diabetes care team determine the right amount of carbs for you.
Reading Food Labels for Carb Information
Food labels provide essential information for carb counting.

Key Information on Food Labels
Serving Size: This indicates the amount of food that the nutrition information is based on. If you consume more than one serving, you'll need to adjust the carb count accordingly.
Grams of Total Carbohydrate: This number includes all carbs: sugar, starch, and fiber.
The Role of Protein and Fat
While carb counting focuses on carbohydrates, it's important to remember that meals typically consist of a mix of carbs, protein, and fat. High protein and fat content can affect how quickly the body absorbs carbs, influencing blood sugar levels.
Tracking your blood sugar levels and discussing them with your diabetes care team, including an RDN/RD and/or CDCES, can help you understand how different foods impact your blood sugar. Continuous glucose monitoring (CGM) or self-monitoring of blood glucose can also be beneficial, especially for insulin dosing.
Food Choices for a Consistent Carbohydrate Diet
When following a CCHO diet, it's important to choose nutrient-rich foods. Opt for whole, unprocessed foods in their natural state, such as vegetables, fruits, whole grains, and lean proteins. Limit processed foods, which often contain added salt, sugar, carbs, fat, or preservatives.
Implementing the Consistent Carbohydrate Diet (CCHO)
The CCHO diet aims to maintain stable blood sugar levels by consuming a consistent amount of carbohydrates each day. This approach can be particularly helpful for individuals with fluctuating blood sugar levels, often associated with diabetes.
Benefits of the CCHO Diet
- Stable Blood Sugar Levels: By consuming a consistent amount of carbs, you can minimize blood sugar spikes and crashes.
- Reduced Medication Needs: Limiting carbs may reduce the need for insulin or other diabetes medications.
- No Side Effects: Unlike some diabetes medications, the CCHO diet has no known side effects.
Replacing Carb Counting with "Choices"
Instead of counting individual carbs, the CCHO diet uses "choices" as units of measurement. One carb choice is equivalent to approximately 15 grams of carbohydrates.

Sample Recipes for a CCHO Diet
Here are a few recipes that can be incorporated into a CCHO meal plan:
Breakfast: Oatmeal with Strawberries and Almonds
- 1 cup old-fashioned rolled oats (not quick cooking, gluten-free)
- 2 cups water
- 1/4 teaspoon salt
- 1/4 cup raspberry fruit spread
- 1/2 teaspoon almond extract
- 2 cups strawberries, quartered
- 1 ounce slivered almonds, toasted
Total carbs: 33
Combine water, oats, and salt in a medium-size pan. Bring to a boil, reduce heat, and simmer 10 minutes uncovered. Remove from heat and let stand 2 minutes. Place the fruit spread in a small microwave-safe bowl and cook on high setting for 15 seconds or until slightly melted. Remove from heat and stir in the extract. Spoon equal amounts of the oatmeal in four bowls. Top with 1 tablespoon fruit spread, 1/2 cup berries, and 1 tablespoon toasted almonds.
Lunch: Ham, Cheese, and Avocado Lettuce Wrap
- 1 teaspoon lime juice
- 1/2 ounce reduced-fat Colby jack cheese
- 1/4 avocado, mashed
- 1 1/2 ounces low-sodium deli ham
- 1 large Bibb lettuce leaf
- 1 teaspoon chili powder
- 2 hard-boiled egg whites
- 12 roasted almonds, unsalted
- 1 green apple
- 3 baby carrots
Put the ham, cheese, and avocado on the lettuce leaf, then roll it tightly and wrap in plastic wrap. Serve it with the egg whites, almonds, green apple, and baby carrots.
Total carbs: 35
Dinner: Chicken and Mushroom Sauté
- 1 pound boneless, skinless chicken breasts
- 1 tablespoon olive oil
- 1/4 cup all-purpose flour
- 1 tablespoon margarine (trans fat-free)
- 10 ounces white (button) mushrooms, sliced
- 1/4 teaspoon black pepper
- 1/3 cup balsamic vinegar
- 1/2 cup low-sodium, fat-free chicken broth
Place the chicken breast in a plastic bag and pound it thin with a mallet. Heat olive oil over medium-high heat in a skillet. Dredge the chicken in flour and coat it on both sides. Add the chicken to the pan and sauté 5 minutes per side. Remove the chicken from the pan and set aside. Melt the margarine in the pan. Add the mushrooms and pepper and cook for 5 minutes. Add the balsamic vinegar to the pan and bring it to a boil to reduce the liquid. Add the chicken broth to the pan and simmer 2 minutes.
