Healthy Net Carbs On Keto: Friend Or Foe?

The keto diet is a low-carb, high-fat diet that can be effective for weight loss and certain health conditions. To stay in ketosis, a person needs to consume up to 50 grams of carbs per day, but some people may need to go under 20 grams to reach ketosis. Net carbs are calculated by subtracting fibre and sugar alcohols from total carbohydrates. Net carbs are an important consideration on the keto diet as they are the only type of carbs that affect blood sugar and kick you out of ketosis. Fibre and sugar alcohols are not digested like other carbohydrates and do not raise blood sugar, so they are not counted towards the daily carb limit. Tracking net carbs instead of total carbs makes the keto diet less restrictive and allows for more variety in food choices, including nutrient-dense, fibre-rich foods.

Net carbs are what remain after subtracting grams of fibre content and sugar alcohols from total carbohydrates per serving

Net carbs are the result of subtracting fibre and sugar alcohols from total carbohydrates. This is because fibre and sugar alcohols are not fully digested by the body and do not cause significant spikes in blood sugar.

Regular or total carbs include the total amount of natural sugars, starches, fibre, and sugar alcohols in a product. Net carbs are what remain after the grams of fibre content and sugar alcohols have been subtracted from the total carbohydrates per serving.

Nutrition Facts labels list the total grams of carbohydrates per serving in a food. This can help you identify whether food manufacturers have added large quantities of sugar alcohols to lower the net carbs of food or if your food has a significant amount of filling fibre.

The formula to calculate net carbs is: total carbs – (fibre + sugar alcohols).

The types of carbohydrates subtracted in the net carb formula include both fibre and sugar alcohols. Foods that are low in net carbs tend to be high in fibre, high in sugar alcohols, or a combination of both. These low-impact carbohydrates are digested at a much slower rate, leading to a prolonged release of glucose into the bloodstream and sustained energy levels.

Fibre is crucial for optimal metabolic and digestive system health. There are two main types of fibre: soluble and insoluble. Soluble fibre can be diluted in water, creating a gel-like substance that slows down the process of food absorption in the body, helping to promote weight loss. Insoluble fibre does not dissolve in water, has no calories, and helps with healthy and regular bowel movements.

Sugar alcohols, also known as polyols, are made of sugar and alcohol molecules but do not contain ethanol. They are primarily used as alternative sweeteners and are commonly found in sugar-free foods. While they are considered alternatives to sugar, they do contain calories and might affect your blood sugar and insulin levels.

Net carbs are a reflection of the glycemic index (GI) of foods. The GI of foods determines how quickly their carbohydrates are digested and enter the bloodstream. Foods with a high GI are known as impact carbs and include white bread, white rice, and sugary cereals. On the other hand, foods that are low-GI tend to be higher in dietary fibre and more nutrient-dense.

Net carbs are essential to a keto diet because they directly affect ketosis. To stay in ketosis, people typically limit carbs to 30-50 grams per day. Tracking net carbs instead of total carbs can be a more sustainable option for keto dieters, allowing them to enjoy nutrient-dense, fibre-rich foods without disrupting ketosis.

Net carbs are a reflection of the glycemic index (GI) of foods

The GI of a food depends on how slowly or quickly the carbohydrates in it are digested and absorbed, affecting blood glucose levels over a period of time, usually 2 hours. Carbohydrate-containing foods with a high GI are quickly broken down during digestion, leading to a rapid release of glucose into the bloodstream. In contrast, low GI foods, like oats, release glucose gradually, resulting in a slower and flatter blood glucose response.

The GI of a food is influenced by factors such as its size, texture, viscosity, and ripeness. For example, an unripe banana typically has a lower GI than a ripe one. Additionally, cooking and processing can impact the GI; for instance, finely ground or smaller food particles have a higher GI because they are more easily absorbed.

When following a keto diet, it is crucial to monitor your net carb intake. The keto diet typically restricts carbs to 20-50 grams per day to maintain ketosis. Net carbs are calculated by subtracting the fibre content from the total carbs in a serving of food. This calculation is essential for keto dieters because it helps them manage their blood sugar levels and stay within their carb limit.

By understanding the GI of foods and calculating net carbs, individuals can make informed choices about their dietary intake, particularly when managing specific health conditions like diabetes or aiming for weight loss.

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

To achieve and maintain ketosis, it is crucial to limit your carbohydrate intake, specifically net carbs, as they directly influence your blood sugar levels. Net carbs are calculated by subtracting fibre and sugar alcohols from total carbohydrates. Fibre and sugar alcohols are not fully digested by the body and have a minimal impact on blood sugar, making them exempt from the carb count on a keto diet.

The recommended net carb intake to stay in ketosis is generally under 50 grams per day, with some sources suggesting a more restrictive approach of 20 grams or less. By tracking your net carb intake, you can effectively manage your carbohydrate consumption and ensure you stay within the recommended range for ketosis.

Net carbs are often referred to as "impact carbs" because they directly impact your blood sugar levels. High-net-carb foods include white bread, white rice, sugary cereals, pasta, bread, grains, certain fruits, and starchy vegetables. On the other hand, low-net-carb foods include animal products like meat, poultry, fish, and eggs, as well as leafy greens, nuts, and certain fruits like avocados.

By focusing on net carbs, you can enjoy a more flexible and sustainable keto diet while still achieving your weight loss and health goals. This approach allows you to include nutrient-dense, fibre-rich foods in your diet without disrupting ketosis.

In summary, net carbs are crucial to the keto diet because they are the deciding factor in whether you achieve and maintain ketosis. By understanding and tracking your net carb intake, you can ensure you stay within the recommended range, optimising the benefits of the keto diet for weight loss, blood sugar control, and improved metabolic health.

Net carbs can be calculated by subtracting fibre and sugar alcohols from total carbs

Net carbs refer to the total amount of digestible carbohydrates in a food product or meal. They are calculated by subtracting fibre and sugar alcohols from the total number of carbohydrates.

Fibre is a type of complex carbohydrate that the body cannot digest. It is not broken down by enzymes in the small intestine and passes through the body undigested. There are two types of fibre: insoluble and soluble. Insoluble fibre creates bulkier stools and can help prevent constipation, while soluble fibre is fermented by the colon into short-chain fatty acids, which are important for gut health.

Sugar alcohols are used to add sweetness to many low-carb foods. The body processes them similarly to fibre, but not all sugar alcohols are equal. Erythritol, for example, is not digested by the body and can be subtracted from the total carbohydrate amount. Other sugar alcohols, like maltitol and sorbitol, do affect blood sugar levels and are partially digested, so only half of their total number of grams can be subtracted from the total carbohydrates.

Calculating net carbs can be beneficial for people with diabetes, as it helps them track their intake of dietary fibre and balance their medications with their carbohydrate intake. It can also increase the number of food choices available, as many fruits and vegetables are rich in fibre and contribute fewer carbohydrates. However, it is important to note that the Food and Drug Administration (FDA) does not recognise the term "net carbs", and instead recommends using the total carbohydrates listed on nutrition labels.

Net carbs are less restrictive than total carbs

Net carbs are calculated by subtracting indigestible carbs, such as fibre and sugar alcohols, from total carbs. This is because fibre is indigestible and cannot be broken down and absorbed by the body. Sugar alcohols are also thought to have a minimal impact on blood sugar levels.

The keto diet is a low-carb, high-fat diet that aims to put the body into a state of ketosis, where the body relies on fat for energy instead of carbohydrates. To stay in ketosis, a person should consume no more than 50 grams of carbs per day.

Counting net carbs instead of total carbs is less restrictive because it allows for a greater consumption of vegetables and other wholesome foods that contain carbohydrates. This makes it easier to stay in ketosis while still eating a wider range of foods.

For example, one cup of raspberries contains 15 grams of total carbs, but only 7 grams of net carbs, as 8 grams of fibre are not counted. Similarly, a protein bar with 21 grams of total carbs has only 3 grams of net carbs when the 14 grams of fibre and 3 grams of sugar alcohols are subtracted.

However, it is important to note that the concept of net carbs is not officially recognised, and the only carbohydrate value regulated by the FDA is the total carbohydrate count, including dietary fibre and sugar. There is also ongoing debate about the value of using net carbs versus total carbs, as focusing only on net carbs may not be the most accurate measure of carb intake.
