The ketogenic (keto) diet is a low-carb, high-fat diet that puts the body into a state of ketosis. To stay in ketosis, a person needs to consume no more than 50 grams of carbohydrates per day. This can be challenging, so it's important to understand the difference between total carbs and net carbs. Net carbs are the number of carbohydrates that are absorbed by the body and impact blood sugar levels. In the UK, net carbs are calculated by subtracting polyols (sugar alcohols) from the total carb count, as fibre is listed separately. This differs from the US calculation, where fibre is included in the total carb count. To calculate net carbs, simply subtract the grams of fibre and sugar alcohols from the total carb content. This will ensure you're on track with your keto diet goals and give you a better understanding of how your food choices impact your health.

Net carbs are the total amount of digestible carbs in a product or meal
Net carbs are the digestible carbohydrates in a food product or meal. They are calculated by subtracting the amount of fibre and sugar alcohols from the total number of carbohydrates. Net carbs are an important consideration for people following a keto diet, which requires limiting carbohydrate intake to up to 50 grams per day. This is because net carbs represent the number of carbohydrates that are absorbed by the body and impact blood sugar levels and insulin response.
In the UK and EU, the calculation for net carbs is: total carbs - polyols = net carbs. Polyols are sugar alcohols that are non-calorific and do not impact the body, for example, erythritol. However, there are some calorific polyols, such as maltitol, sorbitol and xylitol, which should not be deducted from the total carb count.
In the US, the calculation is different as fibre is included in the total carbohydrate count, so the formula is: total carbs - polyols - fibres = net carbs. This is an important distinction to make when calculating net carbs, depending on where a product is from.
To calculate net carbs, you first need to determine the total carb content by reading the nutrition label. Then, subtract the grams of fibre and sugar alcohols to get the net carb count. This calculation can be done manually or by using a net carb calculator.
Net carbs are a useful tool for people following a keto diet as they allow for the inclusion of nutritious, fibre-rich fruits and vegetables in meals. It is generally recommended to stay under 20-25 net carbs on a keto diet to reach the fat-burning state of ketosis quickly.

In the UK, fibre is listed separately to carbs
In the UK, fibre is listed separately from carbohydrates on nutrition labels. This means that the total carbohydrates listed on a food label already exclude fibre. This is different from the US, where the total carbohydrates include fibre, and it is necessary to subtract the fibre content to get the net carbs.
In the UK, to calculate the net carbs of a product, you only need to subtract the polyols from the total carbohydrates. Polyols are sugar alcohols that are non-calorific and do not impact your body, for example, erythritol. However, there are some calorific polyols, such as maltitol, sorbitol, and xylitol, which should not be subtracted from the total carbs.
The formula for calculating net carbs in the UK is:
Net Carbs = Total Carbs - Polyols
This calculation gives you the number of carbohydrates that are absorbed by your body and can impact your blood sugar levels and insulin response. Net carbs are an important consideration for people following a keto diet, as it is crucial to limit carbohydrate intake to stay in ketosis.

Net carbs = total carbs – fibre – sugar alcohols & allulose
Net carbs are the total amount of digestible carbohydrates in a product or a single meal. To calculate net carbs, you need to subtract the amount of fibre and sugar alcohols from the total number of carbohydrates. This is because fibre and sugar alcohols are not digestible and, therefore, do not significantly affect blood sugar levels.
In the UK, the calculation for net carbs is: total carbs – fibre – sugar alcohols (also known as polyols) = net carbs. This differs from the US calculation, where fibre is included in the total carb count, so the calculation is: total carbs – polyols – fibres = net carbs.
For example, let's say a food product has 20 grams of total carbs, 10 grams of fibre, and 10 grams of sugar alcohols. To calculate the net carbs, you would subtract the fibre and half the amount of sugar alcohols from the total carbs:
20 grams (total carbs) – 10 grams (fibre) – 5 grams (sugar alcohols) = 5 grams of net carbs.
It's important to note that not all sugar alcohols are treated equally in this calculation. Erythritol, for instance, has a glycemic index of zero, meaning it has no effect on blood glucose levels. In this case, you would subtract the full amount of erythritol from the total carbs.
Calculating net carbs can be beneficial for people trying to lose weight or manage their blood sugar levels, such as those with diabetes. However, it's always recommended to consult a doctor or dietitian before starting a new diet, especially if you have a health condition.

Net carbs are thought to represent the number of carbohydrates that are actually absorbed by your body
Net carbs refer to the total grams of carbohydrates in a food item minus the grams of fibre and sugar alcohols. Fibre is a type of carbohydrate that resists digestion and is crucial for health and weight control. Sugar alcohols are a type of low-calorie sweetener that is safe to consume in small amounts.
In the UK and EU, the calculation for net carbs is: total carbs – polyols = net carbs. In the US, the calculation is: total carbs – polyols – fibres = net carbs. This is because fibre is listed separately from carbohydrates in the UK and EU, whereas, in the US, fibre is included in the total carbohydrate count.

Tracking your net carbs will help you to stay healthy and lose weight
The keto diet is a low-carb, high-fat diet that can help you lose weight and improve your health. When you're on the keto diet, it's important to track your net carbs to make sure you're staying within the recommended range.
Net carbs are the number of carbohydrates that are absorbed by your body and used for energy. They are calculated by subtracting fibre and sugar alcohols from the total number of carbohydrates. This is slightly different from total carbs, which include all types of carbohydrates, even those that are not absorbed by the body.
Counting net carbs is important because it helps you stay within the recommended range for the keto diet, which is typically less than 20-25 grams of net carbs per day. By tracking your net carbs, you can make sure you're not exceeding this limit, which is crucial for maintaining ketosis, a metabolic state where your body burns fat for energy instead of carbohydrates.
Additionally, tracking net carbs allows you to include more nutritious foods in your diet. For example, you can add plenty of fibre-rich fruits and vegetables, which provide essential vitamins and minerals, while still keeping your carb intake low. This makes it easier to stick to the keto diet and avoid boredom or nutrient deficiencies.
To calculate net carbs, simply read the nutrition label on your food and subtract the grams of fibre and sugar alcohols from the total number of carbohydrates. There are also keto-friendly apps available that can help you track your net carb intake and stay on top of your keto diet goals.
In conclusion, tracking your net carbs is crucial for staying within the recommended range for the keto diet and reaping the weight loss and health benefits it offers. By understanding the difference between net carbs and total carbs, and utilising tools like nutrition labels and apps, you can successfully manage your carb intake and achieve your health and fitness goals.

Frequently asked questions
Net carbs are the number of carbohydrates that are absorbed by your body and have an impact on it. Net carbs are calculated by subtracting fibre and sugar alcohols from the total carbohydrates, as these are not digested by the body and do not impact blood sugar.
The formula for calculating net carbs in the UK is: Net Carbs = Total Carbs - Polyols. This is because, in the UK, fibre is listed separately from carbohydrates on food labels, so you don't need to subtract it from the total.
The recommended net carb intake for keto varies from person to person but is generally between 20-25 grams per day to reach and maintain ketosis. However, some people may be able to consume up to 50 grams of net carbs and still be in ketosis, especially if they are very active.
