Keto Diet: Counting Carbs Or Net Carbs?

The keto diet is a very low-carb, high-fat diet that puts the body into a metabolic state called ketosis, where fat is burned for energy instead of carbohydrates. To stay in ketosis, a person can consume up to 50 grams of carbs per day. However, it is important to distinguish between total carbs and net carbs when following the keto diet. Total carbs refer to the total number of carbohydrates in a food item, while net carbs are calculated by subtracting the grams of fibre and certain sugar alcohols from the total carbohydrates. Net carbs are considered more important than total carbs for keto because they represent the carbs that are absorbed into the body and can impact ketosis. By focusing on net carbs, individuals can still obtain essential fibre and enjoy a wider variety of foods while adhering to the keto diet.

Net carbs are the total carbs minus the grams of fibre content

Net carbs are a crucial concept in the keto diet, which is a very low-carb, high-fat diet that promotes weight loss and improves metabolic health. Net carbs are calculated by subtracting the grams of fibre content from the total number of carbohydrates in a food item. This is important because fibre is a type of carbohydrate that the human body cannot digest, so it does not count towards the total number of carbs that can trigger an insulin response and potentially disrupt ketosis.

The keto diet is based on achieving and maintaining a state of ketosis, where the body burns fat for fuel instead of carbohydrates. To reach and stay in this state, it is essential to restrict carbohydrate intake. Net carbs are the number of carbohydrates that are absorbed into the body and have an impact on ketosis. Some sources of carbohydrates, like fibre and sugar alcohols, are not absorbed into the bloodstream and, therefore, do not count towards your daily allowance of net carbs.

The formula for calculating net carbs is: Net Carbs = Total Carbs – Dietary Fibre – Half of Sugar Alcohols. For example, if a food item contains 20 grams of total carbs, 8 grams of fibre, and 5 grams of sugar alcohols, the net carb count would be 7 grams (20 – 8 – 5 = 7). It is important to note that sugar alcohols, such as xylitol and erythritol, are only partially digested and can still impact blood sugar levels, so only half of their amount is subtracted from the total carb count.

By focusing on net carbs instead of total carbs, individuals on the keto diet can ensure they are getting enough essential fibre while still maintaining ketosis. Net carbs also allow for greater consumption of vegetables and other nutritious, fibre-rich foods. Additionally, tracking net carbs provides more flexibility in daily carb intake and is generally considered a more sustainable approach for long-term weight loss and health goals.

Total carbs include natural sugars, starches, fibre, and sugar alcohols

Total carbs refer to the total number of carbohydrates from all sources. This includes natural sugars, starches, fibre, and sugar alcohols. Natural sugars are found in fruits and vegetables, such as cauliflower, and even in some processed foods. Starches are a type of complex carbohydrate found in foods like bread, rice, and potatoes. Fibre is the portion of carbohydrates found in plants that passes through the body undigested and includes soluble and insoluble fibre. Sugar alcohols are derived from plant sources and are used as alternative sweeteners, such as sorbitol, mannitol, and erythritol.

When reading a nutrition label, the total carbohydrate count includes all of these components. For example, if a food label lists 37 grams of total carbohydrates, there is no need to add the grams of fibre or sugar to this number as they are already included. This total carbohydrate number is important to consider when tracking macronutrients, or "macros", which are the three nutrients the human body needs in the largest quantity: protein, fat, and carbohydrates. On a ketogenic diet, the goal is to get 70-80% of calories from fat, 20-25% from protein, and 5-10% from carbs.

The distinction between total carbs and net carbs is important for those following a ketogenic diet. Net carbs refer to the number of carbohydrates that are absorbed into the body. Since some sources of carbohydrates, like fibre and sugar alcohols, are not absorbed into the bloodstream, they are not included in the daily allowance of net carbs. Net carbs are calculated by subtracting the grams of fibre and sugar alcohols from the total number of carbohydrates. For example, if a food contains 37 grams of total carbs, 4 grams of fibre, and 8 grams of sugar alcohols, the net carb count would be 25 grams (37 - 4 - 8 = 25).

For those on the keto diet, staying within a certain range of net carbs is crucial to maintaining a state of ketosis, where the body burns fat for energy instead of carbohydrates. The recommended amount of net carbs for keto dieters is generally between 20 to 50 grams per day. By focusing on net carbs rather than total carbs, individuals can ensure they are getting enough essential fibre while still adhering to the strict carbohydrate restrictions of the keto diet.

Net carbs are absorbed into the body, unlike some carbs like fibre and sugar alcohols

Net carbs are an important consideration for anyone on a keto diet. They refer to the number of carbohydrates that are absorbed into the body. Net carbs are calculated by subtracting any fibre and sugar alcohols from the total number of carbohydrates. Fibre and sugar alcohols are types of carbohydrates that are not absorbed into the bloodstream and, therefore, do not count towards your daily allowance of net carbs.

Fibre is a unique form of carbohydrate in terms of its digestion and effects on the body. Naturally occurring fibre is not absorbed in the small intestine because the links between sugar units cannot be broken down by the enzymes in the digestive tract. Instead, fibre passes directly into the colon. Insoluble fibre, which makes up about two-thirds of the fibre we eat, does not dissolve in water and helps to prevent constipation by creating bulkier stools. It also provides no calories and has no effect on blood sugar or insulin levels.

Sugar alcohols, on the other hand, are only partially absorbed in the small intestine, and there is a lot of variation among different types. Researchers report that the small intestine absorbs anywhere from 2-90% of sugar alcohols. Some are only briefly absorbed into the bloodstream before being excreted in urine. Sugar alcohols can have varying effects on blood sugar and insulin levels, but these effects are considerably lower than those of sugar.

By focusing on net carbs rather than total carbs, you can ensure your body gets the essential fibre it needs to function properly.

Net carbs are calculated by subtracting the amount of dietary fibre and half the amount of sugar alcohols from the total carbs

Net carbs are an important consideration for anyone following a keto diet. This is because net carbs are the number of carbs that are absorbed into your body. Some sources of carbohydrates, such as fiber and sugar alcohols, are not absorbed into your bloodstream and, therefore, are not part of your daily allowance of net carbs.

The keto diet allows for a maximum of 50 grams of net carbs per day, and the fewer carbs, the better. By focusing on "net" rather than "total" carbs, you won't be denying your body the essential fiber it needs for proper function.

To calculate the net carbs in a food, you need to subtract the amount of dietary fiber and half the amount of sugar alcohols from the total carbohydrates. This can be done by looking at the food's nutrition label.

For example, let's calculate the net carbs in a medium avocado, which contains 12 grams of carbs, 9.2 grams of fiber, and some sugar alcohols.

First, subtract the fiber from the total carbs:

12g carbs – 9.2g fiber = 2.8g net carbs

Next, subtract half the amount of sugar alcohols from the remaining number:

8g net carbs – 0.5g sugar alcohols = 2.3g net carbs

So, the medium avocado has a total of 2.3 grams of net carbs.

Calculating net carbs is a great way to make smart choices about the carbs you eat and to ensure you're getting enough fiber for a healthy metabolism.

Net carbs are essential to a keto diet as they directly affect ketosis

Net carbs refer to the number of carbohydrates that are absorbed into your body. They are calculated by subtracting the grams of fibre and certain sugar alcohols from the total grams of carbohydrates in a food item. Net carbs are what truly matter when following a keto diet because they represent the carbs that actively affect your blood glucose levels.

Fibre, for example, is a type of carbohydrate that your body cannot digest. It passes through your digestive system without being broken down or absorbed, and therefore does not contribute to the carb count that can trigger an insulin response. Similarly, certain sugar alcohols, such as erythritol, are only partially digested and have a minimal impact on blood glucose and ketone levels.

By focusing on net carbs, you can ensure you are not denying your body the essential fibre it needs while still adhering to the strict carbohydrate limits required for ketosis. This approach allows for more flexibility in your diet, enabling you to include nutrient-dense, fibre-rich foods without disrupting ketosis.

Calculating net carbs is simple and can be done by looking at the nutrition label of a food product. First, determine the total carbohydrate content, then identify the amount of fibre and any relevant sugar alcohols. Finally, subtract the fibre and half the amount of sugar alcohols from the total carbohydrates to get the net carb count.

In summary, net carbs are crucial to a keto diet because they directly impact ketosis. By tracking net carbs, you can effectively manage your carb intake, stay within the required limits, and enjoy the benefits of ketosis while maintaining a balanced and nutritious diet.
