The keto diet is a popular, low-carb, high-fat diet that helps people lose weight. To stay in ketosis, the body needs to burn fat instead of carbs for energy, and this is achieved by limiting your carb intake to 30-50 grams per day. Net carbs are the carbs that are absorbed into your body and are calculated by subtracting the grams of fibre and sugar alcohols from the total carbohydrates per serving. Total carbs are the total amount of natural sugars, starches, fibre and sugar alcohols in a product. While it is important to limit your net carbs on keto, it is not necessary to restrict all carbs. Fibre and sugar alcohols are not digested like other carbohydrates and do not raise your blood sugar, so they are not included in net carbs.

What You'll Learn
Net carbs are the only carbs that count on the keto diet
Net carbs are indeed the only carbs that count on the keto diet.
The keto diet is a low-carb, high-fat diet that puts the body into a state of ketosis, where fat is burned for energy instead of carbohydrates. To stay in ketosis, a person can consume up to 50 grams of carbohydrates per day. However, this number refers to "net carbs" rather than "total carbs".
Net carbs are the total grams of carbohydrates in a food minus its grams of dietary fibre and certain sugar alcohols. Dietary fibre is not broken down and absorbed by the digestive tract; instead, it passes through the system until it reaches the colon, where it is either fermented by bacteria or eliminated in faeces. Sugar alcohols, on the other hand, are partially digested and absorbed, and may raise blood glucose and lower ketone levels. However, certain sugar alcohols like erythritol have a minimal impact on blood glucose and ketone levels as they pass into the urine without being metabolised.
By tracking net carbs instead of total carbs, those on the keto diet can enjoy more nutrient-dense, fibre-rich foods without disrupting ketosis. Net carbs allow for more flexibility in one's daily intake of carbs and make it easier to stay within the carb range for ketosis.
The formula for calculating net carbs is: Net Carbohydrates = Total Carbohydrates – (Fibre + Sugar Alcohols).
For example, one medium avocado contains 12 grams of carbs, of which 9.2 grams are fibre. To calculate the net carbs, subtract the fibre from the total carbs: 12g carbs – 9.2g fibre = 2.8g net carbs.
So, while it is important to limit carbs on the keto diet, not all carbs need to be restricted. Net carbs are the only carbs that count.

Net carbs are calculated by subtracting fibre and sugar alcohols from total carbs
Net carbs are a crucial concept for anyone following a keto diet. They are calculated by subtracting fibre and sugar alcohols from the total carbohydrates in a food product. This can be done using the formula:
> Net carbohydrates = total carbohydrates – fibre – sugar alcohols.
The keto diet is a low-carb, high-fat diet that puts the body into a state of ketosis, where fat is burned for energy instead of carbohydrates. To stay in ketosis, it is recommended that a person consumes no more than 50 grams of net carbs per day.
Net carbs are calculated differently from total carbs. Total carbs refer to the total amount of natural sugars, starches, fibre, and sugar alcohols in a product. Net carbs, on the other hand, are the carbs that are absorbed into the body and have an impact on blood sugar levels. Fibre and sugar alcohols are not fully digested by the body and do not significantly affect blood sugar, so they are not included in the net carb count.
By tracking net carbs instead of total carbs, people on the keto diet can enjoy more flexibility in their food choices and consume more nutrient-dense, fibre-rich foods without disrupting ketosis. This approach allows for a less restrictive diet while still supporting weight loss and health goals.
It is important to note that not all fibre and sugar alcohols are created equal. When buying processed goods, reading nutrition labels is crucial as some manufacturers may include processed fibres that can affect blood sugar levels. Additionally, while sugar alcohols are commonly used as alternative sweeteners, they do contain calories and can affect blood sugar and insulin levels, although to a lesser extent than traditional sugars.
In conclusion, calculating net carbs by subtracting fibre and sugar alcohols from total carbs is an essential step for anyone following a keto diet. It allows for better management of carb intake, supports weight loss, and helps maintain the body in a state of ketosis.

Net carbs are a reflection of the glycemic index of foods
Foods with a high GI are known as impact carbs and include white bread, white rice, and sugary cereals. These foods increase blood sugar levels and typically contain more energy than the body can use at once. Studies have found that eating large amounts of these carbs can affect metabolism and increase the complications of chronic diseases like polycystic ovary syndrome (PCOS). They may even increase the risk of certain cancers.
On the other hand, foods that are low-GI tend to be higher in dietary fiber and more nutrient-dense. These include complex carbs found in seeds, nuts, lentils, and many vegetables.
Net carbs are calculated by subtracting fiber and sugar alcohols from total carbohydrates. This calculation is important for people following the keto diet, as it helps them manage their carb intake and stay in ketosis. By focusing on net carbs, people can include more nutrient-dense, fiber-rich foods in their diet without disrupting ketosis.
The keto diet is a very low-carb, high-fat diet that puts the body into a state of ketosis, where fat is burned for energy instead of carbohydrates. This diet has been associated with weight loss and improved metabolic health. To stay in ketosis, people typically limit their carb intake to 30-50 grams per day.

Ketosis is essential for a ketogenic diet
To achieve and maintain ketosis, it is crucial to restrict carbohydrate intake. The recommended amount varies depending on the specific type of ketogenic diet being followed, but generally, it is advised to limit daily carbohydrate consumption to 50 grams or less. This includes counting "net carbs", which are calculated by subtracting fibre and sugar alcohols from total carbohydrates. Net carbs are considered the only carbs that truly affect ketosis, as they are the ones that raise your blood sugar and kick you out of ketosis.
By limiting net carbs, individuals on a ketogenic diet can enjoy more flexibility in their food choices. For example, they can consume nutrient-dense, fibre-rich foods like avocados, berries, nuts, and low-carb vegetables without disrupting ketosis. This approach prevents excessive restriction while still supporting weight loss and overall health goals.
Maintaining ketosis also requires consuming adequate amounts of healthy fats and moderate amounts of protein. Fats become the primary energy source during ketosis, so it is essential to increase fat intake to compensate for the reduction in carbohydrates. However, excessive protein intake should be avoided as it can be converted into glucose, potentially interfering with ketosis.
Overall, achieving and sustaining ketosis is the key to the success of a ketogenic diet. It is important to monitor carbohydrate, fat, and protein intake, with a particular focus on net carbs, to ensure the body remains in this fat-burning state.

Excess protein can prevent ketosis
The ketogenic (keto) diet is a low-carb, high-fat diet that puts the body into a state of ketosis, where fat is burned for energy instead of carbohydrates. To stay in ketosis, a person can consume up to 50 grams of carbohydrates per day. The keto diet also involves moderate amounts of protein, as excess protein can prevent ketosis.
When there is a shortage of carbohydrates in the body, amino acids from the proteins you consume are converted into glucose through a process called gluconeogenesis. This process can prevent your body from going into full ketosis.
However, the idea that too much protein can kick you out of ketosis is a myth. Eating high-fat and high-protein foods can help you stay in ketosis. That being said, it is important to calculate your optimal daily macronutrients (macros) and stick to the daily maximums to ensure you stay in ketosis.
If you are regularly physically active, you may need to increase your protein intake. It is also important to ensure you are consuming enough healthy fats. A good range to aim for is 0.7-0.9 grams of protein per pound of body weight.
To determine whether you are in ketosis, you can test your blood with a ketone and blood glucose meter.
