Carbs On Keto: Total Vs Net Count

The keto diet is a low-carb, high-fat diet that aims to put the body into a state of ketosis, where fat is burned for energy instead of carbohydrates. To stay in ketosis, the daily intake of carbohydrates should be restricted to 20-50 grams, depending on the specific type of keto diet followed. This has led to some confusion about the difference between total carbs and net carbs. Total carbs refer to the total number of carbohydrates in a food item, including sugar, fibre, and sometimes sugar alcohols. Net carbs, on the other hand, are calculated by subtracting the fibre content and certain sugar alcohols from the total carb count. Net carbs are considered the more important metric for keto dieters as they represent the carbs that are absorbed into the body and can kick you out of ketosis if consumed in excess.

Net carbs vs. total carbs

The keto diet is a low-carb, high-fat diet that helps people lose weight quickly and effectively. To follow the keto diet successfully, it is essential to significantly restrict your carbohydrate intake. However, there is some confusion surrounding the difference between net carbs and total carbs, and which one you should focus on when tracking your carbohydrate intake.

Total carbs refer to the total number of carbohydrates in a food item, including all sources such as sugar, fiber, and sometimes sugar alcohols. When reading a standard nutrition label, the total carbohydrate count will include these additional components, and they are already included in the total carbohydrate number.

Net carbs are calculated by subtracting the amount of dietary fiber and certain sugar alcohols from the total number of carbohydrates in a food item. Net carbs are the carbs that are absorbed into your body and can raise your blood sugar levels. On the keto diet, net carbs are considered the only carbs that count because they are the ones that can kick you out of ketosis.

How to Calculate Net Carbs:

The basic formula for calculating net carbs is: Net Carbohydrates = Total Carbohydrates – Fiber – Erythritol (if applicable). When calculating net carbs, it is recommended to only subtract the fiber that naturally occurs in whole foods, as your body may respond differently to added fiber in processed keto and low-carb products.

Additionally, when calculating net carbs for processed foods, you should also subtract half of the sugar alcohol content from the total number of carbs. Sugar alcohols are only partially digested and can still raise blood glucose and lower ketone levels, except for erythritol, which has a minimal impact.

By focusing on net carbs instead of total carbs, you can allow yourself a higher intake of vegetables and other wholesome foods that contain carbohydrates while still staying in ketosis. Net carbs are also easier to calculate and track, making it more convenient for those following the keto diet.

The general consensus among experts is that consuming 20 or fewer grams of net carbs per day will allow most people to stay solidly in ketosis. However, the exact number may vary depending on individual goals and health conditions. For those using the keto diet therapeutically, such as for managing epilepsy, net carbs should be kept close to zero. For others, a range of 5-10% of daily calories (15 to 30 grams) is a good starting point.

Benefits of Using Net Carbs vs. Total Carbs:

Using net carbs instead of total carbs on the keto diet offers several benefits:

• It is less restrictive, allowing for a greater variety of food options, including fruits, vegetables, and nuts, which are high in fiber (total carbs) but low in net carbs.
• It keeps nutrient-dense foods in your diet, ensuring you get crucial micronutrients from fibrous vegetables and other whole foods.
• It simplifies tracking, as you only need to focus on one carb metric instead of two.

In conclusion, understanding the difference between net carbs and total carbs is crucial for anyone following the keto diet. By focusing on net carbs and utilizing the net carb calculation, you can ensure you stay within your carbohydrate limits while still enjoying a diverse and nutritious diet.

Calculating net carbs

To calculate net carbs, it's important to understand the difference between net carbs and total carbs. Total carbs refer to the total number of carbohydrates in a food item, including those from sugar, fiber, and sometimes sugar alcohols. On the other hand, net carbs are calculated by subtracting the amount of dietary fiber and certain sugar alcohols from the total number of carbohydrates. The formula for calculating net carbs is:

Net carbohydrates = total carbohydrates – fiber – (certain) sugar alcohols

When calculating net carbs, it's important to note that not all sugar alcohols are created equal. Sugar alcohols like erythritol have minimal impact on blood glucose and ketone levels, so they can be subtracted from the total carb count. However, sugar alcohols like maltitol and sorbitol can increase blood sugar levels, so they may need to be included in the net carb calculation.

Additionally, it's recommended to only subtract the fiber that naturally occurs in whole foods, as your body may respond differently to added fiber in processed keto and low-carb products.

Here's an example to illustrate the calculation of net carbs:

Let's take 1 cup of cauliflower rice, which contains 4.8 grams of total carbs and 3.2 grams of fiber. To calculate the net carbs, subtract the fiber (3.2 grams) from the total carbs (4.8 grams), resulting in 1.6 grams of net carbs.

Net carbs and ketosis

Net carbs are the total grams of carbohydrates minus its grams of dietary fibre and certain sugar alcohols. Dietary fibre is not broken down and absorbed by your digestive tract. Instead, it passes through your system until it reaches your colon, where it is either fermented by bacteria or eliminated in faeces.

Most sugar alcohols are partially digested and absorbed into the digestive tract and may raise blood glucose and lower ketone levels. However, erythritol has a minimal impact on blood glucose and ketone levels as most of it passes into the urine without being metabolised.

How to Calculate Net Carbs

To calculate net carbs, you take the total carbohydrates and subtract the dietary fibre and sugar alcohols.

Total Carbs vs Net Carbs

Total carbs are the sum of all the carbs you eat in a day. Net carbs are calculated by taking your total carbs and subtracting fibre and certain sugar alcohols.

When calculating net carbs, you can subtract the carbs that come from dietary fibre that is naturally found in whole foods like vegetables, nuts, and seeds. You can also subtract the carbs from erythritol, when used in modest amounts. For added fibre and other sugar alcohols, test your blood glucose and ketone levels to see how your body responds to them.

The ketogenic (keto) diet limits carbohydrates and replaces them with fats, putting the body into a state of ketosis. To stay in ketosis, a person requires up to 50 grams of carbs per day.

According to experts, most people can stay solidly in ketosis if they consume 20 or fewer grams of net carbs per day.

Benefits of Net Carbs vs Total Carbs

You will do better on a keto diet if you switch to tracking net carbs as it is less restrictive. If you limit yourself to 20 grams of net carbs daily, you can eat avocados, berries, nuts, and many low-carb veggies. Your recipe options are endless.

However, on a 20-gram total carb limit, your options evaporate. You will have to kiss fruits, vegetables, and nuts goodbye.

Total carbs and ketosis

The keto diet is a low-carb, high-fat diet that puts the body into a state of ketosis. In ketosis, the body relies on fat for energy instead of carbohydrates, and ketone levels are at least 0.5 mmol/L. To achieve and maintain ketosis, it is essential to restrict carbohydrate intake significantly. However, there is some confusion surrounding the calculation of carb intake due to the difference between total carbs and net carbs.

Total Carbs vs. Net Carbs

Total carbs refer to the total number of carbohydrates from all sources, including sugar, fiber, and sometimes sugar alcohols. On the other hand, net carbs are calculated by subtracting the amount of dietary fiber and certain sugar alcohols from the total carb count. Dietary fiber, found in plant foods, is not broken down and absorbed by the digestive tract; instead, it passes through the system until it reaches the colon, where it is fermented or eliminated. Sugar alcohols, derived from plant sources, are also not digested and, therefore, do not impact blood sugar levels.

Calculating Net Carbs

The formula for calculating net carbs is: Net Carbohydrates = Total Carbohydrates – Fiber – Erythritol (if applicable). When calculating net carbs, it is recommended to subtract the fiber that naturally occurs in whole foods, such as vegetables, nuts, and seeds. Additionally, the carbs from erythritol, a sweetener that does not affect blood sugar or ketone levels, can also be subtracted.

Benefits of Net Carbs

Focusing on net carbs instead of total carbs allows for greater consumption of vegetables and other wholesome foods while still maintaining ketosis. Net carbs also enable the inclusion of nutrient-dense foods, such as fruits, nuts, and low-carb veggies, which are rich in fiber and essential vitamins and minerals.

Carb Targets for Ketosis

To stay in ketosis, the recommended daily carb intake varies depending on the specific type of keto diet followed. The standard ketogenic diet recommends up to 50 grams of carbs per day, with 70% of intake from fat, 20% from protein, and 10% from carbs. Other variations include the cyclical ketogenic diet, with five low-carb days and two high-carb days, and the targeted ketogenic diet, which allows for more carbs around high-intensity workouts.

Tracking Carbohydrates

While there is no one-size-fits-all approach to carbohydrate intake, some general guidelines suggest that staying below 25 grams of net carbs per day is effective for achieving nutritional ketosis. For total carbs, a limit of around 50 grams or less is recommended as a starting point. Ultimately, individuals may need to determine their own carb tolerance through trial and error.

Net carbs and nutrition

When following a keto diet, it is important to understand the difference between total carbs and net carbs. Carbohydrates are one of the macronutrients found in food, and they provide the body with energy. On a keto diet, it is necessary to significantly restrict carbohydrate intake to achieve and maintain a state of ketosis, where the body uses fat instead of carbs for energy.

Total Carbs vs. Net Carbs

Total carbs refer to the total number of carbohydrates in a food item, including sugar, fiber, and sometimes sugar alcohols. Net carbs, on the other hand, are calculated by subtracting the amount of dietary fiber and certain sugar alcohols from the total carbohydrates. Dietary fiber is not digested and absorbed by the body, while sugar alcohols are only partially digested and may raise blood glucose levels.

The formula for calculating net carbs is: Net carbohydrates = total carbohydrates – fiber – erythritol (if applicable). Erythritol is a sugar alcohol that does not affect blood glucose and insulin levels and is often used as a sweetener in keto and low-carb products.

For example, if a food item contains 10 grams of total carbohydrates and 3 grams of fiber, the net carbs would be 7 grams (10 grams - 3 grams = 7 grams). It is important to note that when calculating net carbs, only the fiber that naturally occurs in whole foods should be subtracted, as added fiber in processed products may affect blood glucose levels differently.

Benefits of Net Carbs

Focusing on net carbs instead of total carbs allows for greater flexibility and consumption of vegetables and other nutritious foods that contain carbohydrates. Net carbs also ensure that the body still receives the essential fiber it needs for proper function. Additionally, net carbs can help individuals stay in ketosis, as they exclude carbohydrates that are not absorbed into the body.

Recommended Carb Intake on Keto

To stay in ketosis, individuals on a keto diet should consume no more than 50 grams of net carbs per day, with lower amounts being more effective for weight loss and metabolic health. This equates to 5-10% of daily calories, or 15 to 30 grams, for most people. However, those using keto therapeutically, such as for epilepsy management, may need to keep net carbs closer to zero.

It is important to note that not all keto diets are the same, and the standard ketogenic diet recommends 70% fat, 20% protein, and 10% carbs. Other variations include the cyclical ketogenic diet, targeted ketogenic diet, and high protein ketogenic diet, each with different ratios of carbs, protein, and fat.

Foods to Include and Avoid on Keto

Meats such as beef, lamb, pork, chicken, and fish like cod and salmon are encouraged on the keto diet, as they have very low net carbs. Most green and leafy vegetables also have a low keto net carb count. High-fat foods such as eggs, dairy products, and nuts are used to replace high-carb foods.

Wheat-based products like rice, pasta, and cereals, as well as some fruits, vegetables, beans, and legumes, are high in carbs and should be limited on a keto diet. It is important to check food labels to determine the net carb content of packaged foods.

Tracking Carbohydrates

While there is no one-size-fits-all approach to carbohydrate intake, some general guidelines suggest that staying below 25 grams of net carbs per day is effective for achieving nutritional ketosis. For total carbs, a limit of around 50 grams or less per day is recommended. Ultimately, individuals may need to experiment to find their own carb tolerance.
