The keto diet is a low-carb, high-fat diet that involves taking a very low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes. The diet aims to bring the body into a state of ketosis, where it uses fat for energy instead of carbohydrates. To achieve this, keto dieters must count their net carbs, which is the amount of carbs in a food minus the fibre and sugar alcohol. Fibre and sugar alcohol are not counted because they are not fully absorbed by the body and do not contribute to an insulin response. The keto diet typically restricts net carbs to 20-50 grams per day, but this can vary depending on individual factors such as age, weight, gender, and physical activity level.

Net carbs are the only carbs that count on keto
Net carbs are the only type of carbs that are counted when on a keto diet. This is because net carbs are the only type of carbs that are absorbed into the body and have an impact on blood sugar levels. Net carbs are calculated by taking the total amount of carbohydrates in a food or meal and subtracting the amount of fibre and sugar alcohols. This is because fibre and sugar alcohols are not absorbed into the bloodstream and are not digested like other carbohydrates. Instead, they pass intact into the colon where they are digested by gut bacteria.
Net carbs are important for keto dieters to track because the keto diet is an extremely low-carb, high-fat diet that aims to bring the body into a state of ketosis. Ketosis is a state where the body changes from using glucose as its primary energy source to using ketones created from fat metabolism. By limiting net carbs, keto dieters can ensure they are staying within their carbohydrate target and maintaining ketosis.
The Atkins Diet is another low-carb diet that also focuses on tracking net carbs. On Atkins, net carbs are calculated in the same way as on keto. The Atkins Diet emphasises that net carbs are the only carbs that need to be counted because they are the ones that significantly impact blood sugar levels.
While total carbs include all types of carbohydrates, including fibre and sugar alcohols, these are not fully absorbed by the body. Therefore, when calculating daily carbohydrate consumption on keto, only net carbs are counted. This distinction is crucial for achieving keto diet goals and managing overall health.

Net carbs are calculated by subtracting fibre and sugar alcohols from total carbs
Net carbs refer to the total amount of digestible carbohydrates in a food product or meal. They are calculated by subtracting fibre and sugar alcohols from the total number of carbohydrates. This is because fibre and sugar alcohols are not fully digested and absorbed by the body.
The formula for calculating net carbs is: Net carbs = total carbs – fibre – sugar alcohols.
For example, if a food contains 20 grams of total carbohydrates, 10 grams of fibre, and 10 grams of sugar alcohols, you would subtract 10 grams of fibre and 5 grams of sugar alcohols (as only half of sugar alcohols are counted) from the total carbohydrates: 20 grams – 10 grams – 5 grams = 5 grams of net carbs.
It is important to note that not all sugar alcohols are treated equally in this calculation. Erythritol, for instance, can be completely subtracted from the total carbohydrates, as it is not digested or absorbed by the body at all.
Calculating net carbs is particularly relevant for people on low-carb or keto diets, as it helps them stay within their daily carb limit and maintain a state of ketosis, where the body burns fat for energy instead of carbohydrates.

Net carbs are the carbs absorbed into your body
Net carbs are the number of grams of carbohydrates that significantly impact your blood sugar level. They are the only carbs that are counted on the Atkins and keto diets. Net carbs are the carbs absorbed into your body.
Net carbs are calculated by subtracting the grams of fibre and sugar alcohols from the total grams of carbohydrates. For example, if a food has 31 grams of total carbohydrates and 3.5 grams of fibre, it has 27.5 grams of net carbs. This calculation is important because net carbs are the only carbs that count on the keto diet.
The keto diet is a low-carb, high-fat diet. It involves taking an extremely low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes. The keto diet aims to bring the body into a state of ketosis, where it uses fat for energy instead of carbs. To reach this state, daily carbohydrate consumption is limited to 20-50 grams.
Net carbs are the only carbs that count on keto because they are the ones that are absorbed into the body. Fibre and sugar alcohols, on the other hand, are not absorbed into the bloodstream. They pass intact into the colon, where they are digested by gut bacteria. Therefore, they are not included in the daily allowance of net carbs.
By focusing on net carbs, keto dieters can ensure they are staying within their carbohydrate target without denying their bodies the essential fibre it needs for proper function. Net carbs are typically found in "carby" foods such as pasta, bread, grains, certain fruits, starchy vegetables, and table sugar.

Net carbs are the carbs that can trigger an insulin response
Net carbs are carbohydrates that your body can digest and absorb. They are also known as digestible or available carbs. These are the carbs that can trigger an insulin response, as they are absorbed and used by the body for energy. This is why they are the only carbs that count on the keto diet.
Net carbs are calculated by subtracting fibre and sugar alcohols from the total number of carbohydrates. This is because fibre and sugar alcohols are not fully digested or absorbed by the body. They are known as non-glycemic or non-digestible carbs.
The three main categories of net carbs are simple carbs (glucose, fructose, and lactose), complex carbs (dextrin and cellobiose), and starches (chains of glucose). Foods that are high in net carbs include pasta, bread, grains, certain fruits, starchy vegetables, and table sugar.
On the keto diet, it is important to keep net carbs low to induce ketosis. Ketosis is a state where the body uses ketones created from fat metabolism as its primary energy source instead of glucose. This can lead to weight loss, hunger control, clearer cognition, and reduced inflammation.
While total carbs include all types of carbohydrates, only net carbs are counted when calculating daily consumption on the keto diet. This is because net carbs are the ones that impact blood sugar levels and can interfere with weight loss.

Total carbs include all types of carbohydrates
Net carbs are the number of carbohydrates in a food minus the fibre and sugar alcohol. Fibre and sugar alcohol are subtracted because the body does not fully absorb them. Net carbs are your North Star on Keto.
Total carbs include all carbohydrates present in food. Total carbs include net carbs, fibre, and sugar alcohols. Net carbs are the only carbs that are counted when calculating your daily consumption on the keto diet. The keto diet is a low-carb, high-fat diet. The diet involves taking an extremely low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes.
The total carb diet, on the other hand, allows for a higher amount of carbohydrates and may include more whole grains and fruits. The total carb diet focuses on the total carbohydrates consumed rather than just the net carbs. The total carb diet does not restrict carbohydrate intake but emphasizes whole, unprocessed foods, including fruits, vegetables, whole grains, and legumes while limiting added sugars and refined carbohydrates.

Frequently asked questions
Net carbs are the grams of total carbohydrates in a food minus its grams of total fibre. Fibre is a type of carbohydrate that the body cannot digest, so it doesn't count towards the amount of carbs that can trigger an insulin response.
To calculate net carbs, take the total amount of carbohydrates in a food or meal, then subtract the amount of fibre. The result is the net carb count.
Net carbs are important for the keto diet because they are what is counted when calculating your daily intake. Total carbs are not counted.
The keto diet generally restricts daily net carb intake to between 20 and 50 grams.
Meats such as beef, veal, lamb, pork, chicken and turkey, and fish such as cod, sardines, tuna and salmon have very low net carbs. Most green and leafy vegetables also have an extremely low keto net carb count.
