Carbs And Keto: Understanding Net Carbs

The keto diet is a low-carb, high-fat diet. But what's the difference between carbs and net carbs? Net carbs are the carbs that are absorbed into your body and are the only carbs that count on the keto diet. Total carbs include all types of carbohydrates, including fiber and sugar alcohols, which are not fully absorbed by the body. Net carbs are calculated by subtracting fiber and sugar alcohols from total carbohydrates. For example, if a food has 20 grams of total carbohydrates and 8 grams of fiber, the net carb count is 12 grams. Net carbs are important to track on the keto diet because they directly affect ketosis, the state where the body burns fat for energy instead of carbs.

Net carbs are the carbs that are absorbed into your body

On the other hand, total carbs include all types of carbohydrates, including fibre and sugar alcohols, which are not fully absorbed by the body. Fibre, for example, is not broken down and absorbed by the digestive tract but instead passes through the body until it reaches the colon, where it is either fermented by bacteria or eliminated in faeces.

Sugar alcohols, which are primarily used as alternative sweeteners, can also be partially digested and absorbed into the digestive tract. However, erythritol has a minimal impact on blood glucose and insulin levels as most of it passes into the urine without being metabolised.

By tracking net carbs, you can manage your carb intake more effectively and stay within your carb range for ketosis. The formula to calculate net carbs is: Net carbohydrates = total carbohydrates – fibre – erythritol (if applicable).

For example, one cup of cauliflower rice contains 4.8 grams of total carbs and 3.2 grams of fibre. To get its net carbs, you subtract the fibre (3.2 grams) from the total carbs (4.8 grams), which leaves you with 1.6 grams of net carbs.

Total carbs include all types of carbohydrates, including fibre and sugar alcohols

Total carbs refer to the overall grams of carbohydrates in a food item, encompassing all types of carbohydrates, including natural sugars, starches, fibre, and sugar alcohols. In contrast, net carbs are calculated by subtracting the fibre content and specific sugar alcohols from the total carbohydrates. This distinction is crucial for individuals adhering to a keto diet, as net carbs are the primary focus when monitoring daily carbohydrate intake.

Total carbs, as the name suggests, encompass all types of carbohydrates present in a food product. This includes both simple and complex carbohydrates. Simple carbs, such as glucose, fructose, and lactose, are quickly absorbed by the body, leading to spikes in blood sugar and insulin levels. On the other hand, complex carbs, like dextrin and cellobiose, take longer to break down and provide a more sustained release of energy.

Fibre, a type of carbohydrate that the human body cannot fully digest, is an essential component of total carbs. Unlike other carbohydrates, fibre passes through the digestive tract relatively intact, reaching the colon where it is fermented by gut bacteria or eliminated through faeces. This process aids in digestive health and promotes regular bowel movements. Additionally, fibre helps to create a sense of fullness, supporting weight loss efforts.

Sugar alcohols, another component of total carbs, are derived from plant sources and commonly used as alternative sweeteners. Examples include xylitol, erythritol, sorbitol, and maltitol. While they do not contain ethanol, they still provide calories and may impact blood sugar and insulin levels to some extent.

When following a keto diet, it is crucial to differentiate between total and net carbs. Net carbs are calculated by subtracting fibre and certain sugar alcohols from the total carb count. This calculation is essential because net carbs are the primary factor in determining whether an individual remains in ketosis, the desired metabolic state for keto dieters. By subtracting fibre and specific sugar alcohols, individuals can more accurately assess their carb intake and ensure they stay within the keto guidelines.

In summary, total carbs refer to the cumulative amount of all carbohydrates in a food item, including fibre and sugar alcohols. Net carbs, on the other hand, are calculated by deducting the fibre content and specific sugar alcohols from the total carb count. This distinction is vital for keto dieters as it helps them monitor their carb intake and maintain ketosis, ultimately supporting their health and weight loss goals.

Net carbs are calculated by subtracting fibre and sugar alcohols from total carbs

Net carbs are the number of total carbohydrates in a food item minus its grams of fibre and sugar alcohols.

Net carbs = total carbs – fibre – sugar alcohols

Net carbs are the only type of carbs that count on the keto diet. This is because net carbs are the carbs that are absorbed and used by the body for energy. Fibre and sugar alcohols, on the other hand, are not digested like other carbohydrates. They pass through the digestive tract intact and are then broken down by gut bacteria, creating beneficial short-chain fatty acids. Fibre and sugar alcohols do not raise your blood sugar and therefore do not count towards the amount of carbs that can trigger an insulin response.

Total carbs include all types of carbohydrates, including fibre and sugar alcohols, which are not fully absorbed by the body.

When calculating net carbs, it is recommended to only subtract the fibre that occurs naturally in whole foods, such as vegetables, nuts, and seeds. This is because your body may respond differently to some forms of "added fibre" in keto and low-carb products.

Sugar alcohols are made from sugar and alcohol molecules but do not contain ethanol, the compound that causes intoxication. They are primarily used as alternative sweeteners and commonly found in sugar-free foods. While they are considered alternatives to sugar, they do contain calories and may affect your blood sugar and insulin levels.

One cup of cauliflower rice contains 4.8 grams of total carbs and 3.2 grams of fibre. To get its net carbs, you subtract the fibre (3.2 grams) from the total carbs (4.8 grams), which leaves you with 1.6 grams of net carbs.

Another example is a medium avocado, which contains 12 grams of carbs, of which 9.2 grams is fibre. Subtracting the fibre from the total carbs gives you 2.8 grams of net carbs.

Calculating net carbs can be more straightforward when starting with whole foods, which consist of natural sugars and fibre without having to consider sugar alcohols.

Net carbs are the only carbs that count on the keto diet

The keto diet is a low-carb, high-fat diet. The aim is to put your body into a state of ketosis, where it burns fat for fuel instead of carbohydrates. To achieve this, you need to restrict your carbohydrate intake. But not all carbs are created equal.

When you look at a food label, you'll see a total carbohydrate count. This includes all types of carbohydrates, such as sugar, fiber, and sometimes sugar alcohols. However, when you're on the keto diet, you only need to count the net carbs.

Net carbs are calculated by taking the total carbohydrates and subtracting the fiber and sugar alcohols. This is because fiber and sugar alcohols are not fully digested by the body and don't have the same impact on ketosis. They pass through the digestive tract mostly intact and are then fermented by bacteria in the colon, or eliminated through feces.

For example, let's take an avocado. A medium avocado has 12 grams of total carbohydrates, but 9.2 grams of fiber. Subtracting the fiber from the total carbohydrates gives us 2.8 grams of net carbs.

Another example is cauliflower. One cup of cooked cauliflower florets contains 5 grams of total carbohydrates. It also has 2 grams of fiber, which can be subtracted to give us 3 grams of net carbs.

By tracking net carbs instead of total carbs, you have more flexibility in your diet. You can include more nutrient-dense, fiber-rich foods without disrupting ketosis. This makes the keto diet less restrictive and helps you get the nutrients you need to support your health.

So, when you're counting your carbs on the keto diet, remember that net carbs are the only carbs that count. This will help you make smart choices about the carbs you eat and ensure you stay within your carb range for ketosis.

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

High-GI foods, also known as impact carbs, include white bread, white rice, and sugary cereals. These foods cause a rapid increase in blood sugar levels. When these high-GI carbs enter the bloodstream, they often contain more energy than the body can use at once. Studies have shown that eating large amounts of these carbs can negatively 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, low-GI foods tend to be higher in dietary fibre and more nutrient-dense. These include complex carbs found in seeds, nuts, lentils, and many vegetables. Low-GI or low-impact carbohydrates are digested more slowly, resulting in a slower release of glucose into the bloodstream and sustained energy levels. This slower release of glucose helps to prevent insulin spikes.

Net carbs are calculated by subtracting fibre and sugar alcohols from total carbohydrates. Fibre is a type of carbohydrate that the body cannot digest, so it does not impact blood sugar levels in the same way as other carbohydrates. Sugar alcohols, while containing calories and potentially impacting blood sugar, are only partially digested and absorbed.

By tracking net carbs, individuals on the keto diet can more effectively manage their carb intake and stay within the required range for ketosis. This allows for greater flexibility and a less restrictive diet, as well as promoting weight loss and improving metabolic health.
