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 and maintain ketosis, it is crucial to monitor your carbohydrate intake, specifically the number of net carbs in your food. Net carbs refer to the carbohydrates absorbed into your body, excluding sources like fibre and sugar alcohols, which are not fully absorbed. To calculate net carbs, you subtract the amount of fibre and half the sugar alcohol content from the total carbohydrates. This calculation ensures you stay within the recommended daily net carb intake of 20 to 50 grams on the keto diet.

Net carbs are the total carbs minus fibre and certain sugar alcohols
Net carbs are a key consideration for anyone following a keto diet. They refer to the number of carbohydrates that are absorbed into your body and are calculated by subtracting the amount of fibre and certain sugar alcohols from the total carbohydrate amount.
Fibre is not included in the number of net carbs because it is a type of carbohydrate that the body cannot digest and turn into glucose for energy. Instead, it passes through the digestive system and is either fermented by bacteria or eliminated in faeces. On the other hand, net carbs are absorbed into the bloodstream and are an important source of energy.
Sugar alcohols, which are often used as sweeteners in keto and low-carb products, are also partially digested and absorbed into the digestive tract. They can raise blood glucose and lower ketone levels. However, certain sugar alcohols like erythritol have a minimal impact on blood glucose and ketone levels because they pass into the urine without being metabolised.
To calculate the net carbs in a food item, you need to look at the nutrition label and do some simple arithmetic. First, determine the total amount of carbohydrates, including fibre and any sugar alcohols (sometimes listed as erythritol). Then, subtract the amount of fibre and half the amount of sugar alcohols from the total carbohydrate amount. The result is the net carb count.
For example, if a food has 20 grams of total carbohydrates, 8 grams of fibre, and 5 grams of sugar alcohols, the net carb count would be 12 grams (20 grams total carbs - 8 grams fibre - 2.5 grams sugar alcohols = 12 grams net carbs).
By focusing on net carbs, individuals on the keto diet can ensure they stay within their daily allowance while still consuming essential fibre for proper bodily function.

To get into ketosis, most people need to consume under 50 grams of net carbs per day
Net carbs are all the carbohydrates in food that can be absorbed and used by the body for energy. On the keto diet, you are allowed to have no more than 50 grams of net carbs per day. The fewer net carbs, the better. This is because the keto diet aims to bring the body into a state of ketosis, where the body changes from using glucose as its primary energy source to using ketones created from fat metabolism.
To calculate net carbs, you need to subtract the amount of fibre and sugar alcohols from the total amount of carbohydrates. 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 note that the amount of net carbs you should consume on a keto diet will depend on your age, weight, gender, and physical activity level. Additionally, different types of keto diets allow for different amounts of carbs, protein, and fat. For instance, the standard ketogenic diet consists of 70% fat, 20% protein, and 10% carbs.
Before starting a keto diet, it is recommended to consult a doctor or dietitian to ensure it is safe and suitable for your individual needs.

Net carbs are the carbs absorbed into your body
Net carbs are the number of carbohydrates in a food or meal that can be absorbed and used by the body for energy. They are calculated by subtracting the amount of dietary fibre and certain sugar alcohols from the total number of carbohydrates. Net carbs are important to consider when following a keto diet, as the body can absorb and use them for energy.
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 and put the body into a state of ketosis. In ketosis, the body uses fat for energy instead of carbohydrates. To stay in ketosis, a person can consume up to 50 grams of net carbs per day, although the fewer net carbs, the better.
Net carbs can be calculated by looking at the nutrition label on food products. First, determine the total amount of carbohydrates in a food or meal. Then, determine the amount of fibre and any sugar alcohols (sometimes shown as erythritol on nutrition labels). Finally, subtract the amount of fibre and half the amount of sugar alcohols from the total amount of carbohydrates. The result is the net carb count.
For example, if a food has 20 grams of total carbohydrates, 8 grams of fibre, and 5 grams of sugar alcohols, the net carb count would be 12 grams (20 grams of total carbs - 8 grams of fibre - 2.5 grams of sugar alcohols = 12 grams of net carbs).
It is important to note that net carbs are not the same as total carbs. Total carbs include all types of carbohydrates, including fibre and sugar alcohols, which are not fully absorbed by the body. By focusing on net carbs rather than total carbs, individuals can ensure they are not denying their bodies the essential fibre needed for proper function.

Net carbs can be calculated by looking at food labels and doing some simple arithmetic
For example, if a food has 20 grams of total carbohydrates, 8 grams of fibre, and 5 grams of sugar alcohols, the net carb count would be 12 grams (20 grams of total carbs - 8 grams of fibre - 2.5 grams of sugar alcohols = 12 grams of net carbs). It is important to note that net carbs are absorbed into the body, while some sources of carbohydrates like fibre and sugar alcohols are not.
The keto diet focuses on limiting carbohydrate intake to a maximum of 20-50 grams of net carbs per day, which can help the body achieve a state of ketosis. This involves burning fat for energy instead of carbohydrates, which can lead to weight loss and other potential health benefits. By calculating net carbs, individuals can make informed choices about their food intake and ensure they stay within the recommended range for the keto diet.

The keto diet is a high-fat, moderate-protein, very low-carb eating plan
The keto diet is a high-fat, moderate-protein, and very low-carb eating plan. It involves drastically reducing your carbohydrate intake and substituting carbs with fats. This shift puts your body into a metabolic state called ketosis, where it burns fat instead of carbs for energy.
To achieve and maintain ketosis, you need to limit your daily net carb intake. Net carbs are the total grams of carbohydrates in a food item minus its grams of dietary fibre and certain sugar alcohols. On the keto diet, you should aim for 20 to 50 grams of net carbs per day.
To calculate the net carbs in a food item, follow these steps:
- Determine the total amount of carbohydrates by checking the nutrition label.
- Find out the amount of dietary fibre in the food.
- If the food is processed, identify if it contains any sugar alcohols.
- Subtract the amount of dietary fibre and half the amount of sugar alcohols (if any) from the total amount of carbohydrates. The result is the net carb count.
For example, if a food has 20 grams of total carbohydrates, 8 grams of dietary fibre, and 4 grams of sugar alcohols, the net carb count would be 12 grams (20 grams - 8 grams - 2 grams = 12 grams).
By focusing on net carbs, you can still consume essential fibre while staying within your daily carb limit. However, it's important to note that not all fibre sources are created equal. Your body may respond differently to some forms of "added fibre" in keto and low-carb products, so it's recommended to test your blood glucose and ketone levels after consuming these products.
In addition to calculating net carbs, it's crucial to prioritise whole foods, avoid added sugars, and carefully read nutrition labels when following the keto diet.
