Counting net carbs is important for people on the keto diet because it helps them stay in ketosis. Net carbs are the number of carbohydrates that are absorbed by the body and impact blood sugar levels and insulin response. On the keto diet, it is recommended to consume fewer than 50 grams of net carbs per day, with some sources suggesting a range of 15 to 30 grams. Net carbs can be calculated by subtracting dietary fibre and certain sugar alcohols from the total carbohydrate content of a food. This calculation is important because it helps individuals on the keto diet monitor their carbohydrate intake and ensure they do not exceed their daily limit, which can be challenging due to the restrictive nature of the diet.
What You'll Learn
Net carbs are the carbs absorbed into your bloodstream
Net carbs are the only carbs that count on the keto diet. They are the carbs that are absorbed into your bloodstream and kick your body into ketosis, a metabolic state where it burns fat for energy instead of carbohydrates. Net carbs are calculated by subtracting fibre and sugar alcohols from the total number of carbohydrates in a food item because these are not fully absorbed by the body.
Net carbs are the carbs that raise your blood sugar. They include simple carbs like glucose, fructose, and lactose, complex carbs like dextrin and cellobiose, and starches, which are chains of glucose. These "carby" foods are high in net carbs: pasta, bread, grains, certain fruits, starchy vegetables, and table sugar.
To calculate the net carbs in a food item, you can use the following equation: Net carbs = total carbs - fibre - sugar alcohols. For example, if a food item has 20 grams of total carbohydrates and 8 grams of fibre, the net carb count is 12 grams.
It is important to track net carbs on a keto diet because it ensures you stay within your carbohydrate target and helps you maintain nutritional ketosis. Counting net carbs is also less restrictive than counting total carbs, allowing you to include nutrient-dense foods like fruits, vegetables, and nuts in your diet.
By focusing on net carbs, you can better manage your blood sugar and insulin levels, which is crucial for triggering the fat-burning state of ketosis and reaping the benefits of the keto diet, such as weight loss, hunger control, and reduced inflammation.

Total carbs include all carb components, even those unabsorbed
The keto diet is a low-carb, high-fat diet. It involves taking a very low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes. On a keto diet, you're getting about 70-80% of your calories from fat, 20-25% from protein, and 5-10% from carbs. This is why there is a large focus on tracking your carbohydrate intake.
Total carbs include all types of carbohydrates, including fiber and sugar alcohols, which are not fully absorbed by the body. Net carbs, on the other hand, are all the carbohydrates in food that can be absorbed and used by the body for energy. Net carbs are calculated by subtracting fiber and sugar alcohols from the total carbohydrates. This is because fiber and sugar alcohols are not digested like other carbohydrates. Instead of breaking down into glucose and elevating blood sugar, they pass through the digestive tract intact and are then broken down by gut bacteria.
When you're on a keto diet, it's important to track your net carbs to make sure you're staying within your carbohydrate target. Most keto diets have you aiming for between 20 to 50 grams of net carbs per day. This can be calculated by looking at the nutrition label of the food you're eating or finding the nutrition facts online. For example, one cup of cooked cauliflower florets contains 5 grams of total carbohydrates, but only 3 grams of net carbs since it contains 2 grams of fiber.
By focusing on net carbs, you can include more nutrient-dense foods in your diet, such as avocados, berries, nuts, and low-carb vegetables. These foods are high in fiber (total carbs) but low in net carbs. Most people would benefit from increasing their fiber intake, which has been linked to better digestive and cardiovascular health.

Net carbs are calculated by subtracting dietary fibre from total carbs
The keto diet is a low-carb, high-fat diet. It involves taking a very low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes. On the keto diet, it is important to keep track of your net carbs, which are calculated by subtracting dietary fibre from total carbs.
Total carbs refer to the total number of carbohydrates from all sources, including sugar, fibre, and sometimes sugar alcohols. On the other hand, net carbs refer to the total carbs minus the fibre. Net carbs are the only carbs that count on the keto diet because they are the carbs that can be absorbed and used by the body for energy. Fibre, on the other hand, is not digested by the body and does not impact blood sugar levels.
To calculate net carbs, simply subtract the amount of fibre from the total amount of carbohydrates. For example, if a food has 20 grams of total carbohydrates and 8 grams of fibre, the net carb count would be 12 grams. Most keto diets recommend limiting net carbs to between 20 and 50 grams per day.
It is important to note that sugar alcohols, such as xylitol and erythritol, are also not counted towards the total carb count as they are not digested by the body and do not impact blood sugar levels. However, some sugar alcohols, such as maltitol and sorbitol, may still have an impact on blood sugar levels.
By focusing on net carbs, the keto diet allows for the inclusion of nutrient-dense foods such as fruits, vegetables, and nuts, which are high in fibre but low in net carbs. This makes the keto diet less restrictive and ensures that individuals still consume important micronutrients.

Counting net carbs allows for more nutritious food choices
Counting net carbs is essential when following a ketogenic diet, as it helps you stay within the recommended range of 70-80% fat, 20-25% protein, and 5-10% carbohydrates. Net carbs are calculated by subtracting fibre and sugar alcohols from the total carbohydrate count, and they are the only carbs that count towards your daily intake. This distinction is crucial because fibre and sugar alcohols are not digested like other carbohydrates and do not impact your blood sugar levels.
By focusing on net carbs, you can include more nutritious foods in your diet while still maintaining ketosis. For example, avocados, berries, nuts, and low-carb vegetables are all excellent sources of fibre and other essential nutrients. They are also relatively high in total carbohydrates, but because these are mostly fibre, they have a low net carb count. Including these foods in your diet ensures you get the benefits of their vitamins, minerals, and fibre, which can improve your overall health and digestion.
In contrast, a strict total carb count could lead to the exclusion of these nutrient-dense foods, potentially resulting in nutritional deficiencies. For example, a cup of cooked cauliflower contains 5 grams of total carbohydrates but only 3 grams of net carbs because 2 grams are fibre. If you were only counting total carbs, you might avoid cauliflower and other healthy, fibrous vegetables, which could negatively impact your health in the long run.
Additionally, a diet that includes net carbs tends to be less restrictive. For instance, if you limit yourself to 20 grams of net carbs per day, you can still enjoy a variety of fruits, vegetables, and nuts. However, restricting total carbs to 20 grams would mean eliminating these food groups almost entirely. This flexibility in the keto diet can make it easier to adhere to and ensure you get a diverse range of nutrients.
Finally, counting net carbs can help you make more informed choices about the types of carbohydrates you consume. While net carbs include simple carbs, complex carbs, and starches, not all sources of these are equal. For example, sugar alcohols like xylitol and erythritol are generally considered safe on the keto diet because they don't impact blood sugar levels. On the other hand, some processed "low-carb" or "keto-friendly" products may still contain ingredients that raise blood sugar, such as dextrose or cane sugar juice. By understanding net carbs, you can make better decisions about which carbohydrates to include in your diet and ensure you're getting the full benefits of the keto diet.

Net carbs are important for staying in ketosis
When following a ketogenic diet, it is crucial to monitor your daily carbohydrate consumption to ensure you stay within the recommended range. Net carbs are the key metric to focus on, as they represent the amount of carbohydrates that can trigger an insulin response. Insulin is a hormone that helps regulate blood sugar levels, and too much of it can prevent your body from entering the state of ketosis.
Ketosis is a metabolic state where your body becomes extremely efficient at burning fat for energy instead of carbohydrates. This is achieved by drastically reducing your carbohydrate intake and replacing it with healthy fats. By minimizing your net carb consumption, you can effectively stimulate your body to utilize fat as its primary fuel source, promoting weight loss and improved blood sugar control.
To calculate your net carb intake, simply subtract the amount of fiber and sugar alcohols from the total carbohydrate count. For example, if a food contains 20 grams of total carbohydrates, and 5 grams of fiber, the net carb count would be 15 grams. Aiming for a net carb intake of 20-50 grams per day is generally recommended for most keto diets.
It is important to note that not all carbohydrates are created equal. Some "carby" foods, such as pasta, bread, grains, certain fruits, starchy vegetables, and table sugar, are high in net carbs and should be limited on a keto diet. However, foods like avocados, berries, nuts, and low-carb vegetables are lower in net carbs and can be enjoyed in moderation while still maintaining ketosis.
In summary, net carbs are crucial for staying in ketosis because they represent the digestible carbohydrates that can impact your blood sugar and insulin levels. By keeping your net carb intake within the recommended range, you can effectively stay in ketosis and reap the potential benefits of the keto diet, such as weight loss, reduced inflammation, and improved blood sugar control.

Frequently asked questions
Net carbs are the number of carbohydrates that are absorbed by your body and used for energy. Net carbs = total carbs – fibre.
Net carbs are important because they help you stay in ketosis, which is the goal of the keto diet. Ketosis is a metabolic state where your body shifts from burning carbs for energy to burning fat for fuel.
The standard ketogenic diet recommends consuming as few as 20 grams of net carbs per day, which equates to 5-10% of your total calorie intake. However, the right number of net carbs varies from person to person.
To calculate net carbs, take the total carbohydrates and subtract the grams of fibre and sugar alcohols. The remaining amount is the net carb count.
On keto, you should avoid high-carbohydrate foods such as most fruits, pasta, potatoes, candy, rice, and bread. Instead, focus on low-carb vegetables (especially those that grow above ground), avocados, berries, cocoa powder, dark chocolate, and shirataki noodles.
