The keto diet is a low-carb, high-fat diet that 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 restrict their carbohydrate intake, but there is some confusion around whether they should be limiting their total carb intake or focusing on net carbs. Total carbs include all types of carbohydrates, while net carbs are the carbs that are absorbed and used by the body for energy. Net carbs are calculated by subtracting the amount of dietary fibre and certain sugar alcohols from the total number of carbohydrates. For keto dieters, it is generally recommended to focus on net carbs, as these are the carbs that can trigger an insulin response and prevent the body from entering ketosis.

| Definition | Net carbs are the total carbohydrates minus the fiber and sugar alcohols. |
| Formula | Net carbohydrates = total carbohydrates – fiber – erythritol (if applicable) |
| Daily Intake | 20-50 grams |
| Calculation | Net carbs = total carbs – dietary fiber – half of sugar alcohols |
What You'll Learn
Net carbs are the carbs left over after subtracting fibre and sugar alcohols
Net carbs are a crucial concept for anyone following a keto diet. The keto diet is a low-carb, high-fat diet that aims to bring the body into a state of ketosis, where it uses fat for energy instead of carbohydrates. To achieve this, it's important to understand and calculate net carbs accurately.
Net carbs refer to the carbohydrates in food that can be absorbed and used by the body for energy. They are calculated by subtracting fibre and sugar alcohols from the total carbohydrate count. Fibre is a type of carbohydrate that the body cannot digest, so it doesn't count towards the total that can trigger an insulin response. Similarly, sugar alcohols are only partially digested, so they are also subtracted from the total carb count.
The formula for calculating net carbs is: Total Carbohydrates – Fibre – Sugar Alcohols = Net Carbs. For example, if a food has 20 grams of total carbohydrates, and 8 grams of fibre, the net carb count would be 12 grams. It's important to note that some definitions suggest subtracting only half of the sugar alcohols since they are partially digestible.
The keto diet recommends limiting daily net carb intake to between 20 and 50 grams. This strict limit is intended to induce ketosis, where the body changes its primary energy source from glucose to ketones created from fat metabolism. By focusing on net carbs, individuals on the keto diet can ensure they are staying within their carbohydrate target while still consuming essential fibre.
In summary, net carbs are an important concept for keto dieters as they represent the carbohydrates that are absorbed and used by the body for energy. By subtracting fibre and sugar alcohols from the total carb count, keto dieters can accurately track their carb intake and work towards achieving the desired state of ketosis.

Total carbs include all types of carbohydrates
Fiber is a complex healthy carbohydrate that the body cannot break down easily. It can be soluble or insoluble, with soluble fiber able to dissolve in water and insoluble fiber passing through the intestines to stimulate digestion. Fiber is found in plant-based foods such as fruits, vegetables, nuts, seeds, beans, and whole grains. It is recommended that adults consume 25 to 30 grams of fiber per day.
Sugar alcohols, on the other hand, are carbohydrates that are not completely absorbed by the body. They are often used as sweeteners and can be found in processed foods.
Fully digestible carbohydrates are those that the body can easily break down and use for energy. These include starches, which are complex carbohydrates found in bread, cereal, pasta, and certain vegetables like potatoes, peas, and corn.
When following a total carb diet, it is important to focus on whole, unprocessed foods. This includes fruits, vegetables, whole grains, and legumes, while limiting added sugars and refined carbohydrates. By including a variety of complex carbohydrates, individuals can benefit from increased fiber intake, improved digestive health, and sustained energy levels throughout the day.
It is worth noting that the body can convert excess glucose, which is the result of breaking down carbohydrates, into fat. Therefore, while total carbs provide a range of health benefits, it is important to monitor overall intake and prioritize complex carbs over simple carbs to maintain a balanced and nutritious diet.

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 a very low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes. This puts your body into a metabolic state called ketosis, which makes your body more efficient at burning fat for energy.
When it comes to carbohydrates on the keto diet, net carbs are the only carbs that count. Net carbs are the total grams of carbohydrates in any given food minus its grams of dietary fibre and certain sugar alcohols. Net carbs are the carbs that are absorbed into your body and can be used for energy. They are the carbs that can trigger an insulin response and prevent your body from going into ketosis.
To calculate net carbs, you subtract the amount of dietary fibre and half the amount of sugar alcohols from the total carbohydrate amount. For example, if a food has 20 grams of total carbohydrates and 8 grams of fibre, the net carb count would be 12 grams.
It is important to track your net carb intake to ensure you stay in ketosis. Most keto diets recommend consuming between 20 to 50 grams of net carbs per day.
By focusing on net carbs, you can still include fibrous and nutritious foods in your diet, such as avocados, berries, nuts, and low-carb vegetables. This makes the keto diet less restrictive and ensures you get a variety of crucial micronutrients.

Net carbs are the carbs that raise your blood sugar
Net carbs are the grams of total carbohydrates in a food item minus its grams of total fiber. Fiber is a type of complex carbohydrate that the body cannot digest. This means it does not count toward the amount of carbs that can trigger an insulin response, which, in excess, can prevent your body from going into a state of ketosis.
Net carbs are the carbs that are absorbed into your body and are the ones that matter when it comes to keto. They are determined by removing fiber and sugar alcohols from the total carbohydrates count. The keto diet is a low-carb, high-fat diet that involves taking an extremely low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes.
When people eat foods containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood. As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage. As the cells absorb blood sugar, the levels in the bloodstream begin to fall, prompting the pancreas to make glucagon, a hormone that signals the liver to start releasing stored sugar.
Carbs that are not net carbs, such as fiber, are not absorbed into the bloodstream and therefore do not contribute to raising your blood sugar.

Net carbs can be calculated by adding simple, complex and starch carbs
Net carbs refer to the total amount of digestible carbohydrates in a food product or meal. They are calculated by subtracting the amount of indigestible carbohydrates (dietary fibre and some sugar alcohols) from the total amount of carbohydrates. Net carbs can be calculated for whole foods and processed foods.
To calculate net carbs in whole foods, you subtract the fibre from the total number of carbs. For example, if a food contains 20 grams of total carbs and 10 grams of dietary fibre, it has 10 grams of net carbs.
To calculate net carbs in processed foods, you need to know the amount of fibre and sugar alcohols in the food. First, subtract the fibre from the total carbs. Then, subtract half the amount of sugar alcohols from this new number. For example, if a food contains 20 grams of total carbs, 10 grams of fibre, and 10 grams of sugar alcohols, it has 5 grams of net carbs (20 grams of total carbs - 10 grams of fibre = 10 grams; 10 grams - 5 grams (half the sugar alcohols) = 5 grams of net carbs).
It is important to note that not all sugar alcohols are treated equally in these calculations. Erythritol, for instance, can be completely subtracted from the total carbs, rather than halved.
Net carbs are an important consideration for people on the keto diet, which is a very low-carb, high-fat diet. Net carbs are the carbs that are absorbed into the body and are the ones that impact ketosis. Ketosis is a metabolic state in which the body burns fat for energy instead of carbohydrates. On the keto diet, net carb intake is limited to between 20 and 50 grams per day.
