The keto diet is a low-carb, high-fat diet that involves taking a very low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes. On a keto diet, it is important to track your carbohydrate intake. However, there is some confusion about whether one should track total carbs or net carbs. Total carbs include all types of carbohydrates, including fiber and sugar alcohols, which are not fully absorbed by the body. On the other hand, net carbs are all the carbohydrates in food that can be absorbed and used by the body for energy. Net carbs are calculated by subtracting fiber and sugar alcohols from total carbohydrates. While some people argue that tracking net carbs is less restrictive and allows for more nutrient-dense foods in your diet, others argue that it is misleading and inaccurate as the way each individual processes and metabolizes non-impact carbs is different.

Net carbs are the only carbs that count on keto
Net Carbs: The Only Carbs That Count on Keto
The keto diet is a low-carb, high-fat diet. It involves taking a very low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes. The diet aims to bring the body into a state of ketosis, where it uses fat for energy instead of carbohydrates.
When it comes to carbohydrates, not all are created equal. This is especially true on the keto diet, where only one type of carbohydrate is counted: net carbs. Net carbs are the carbohydrates that are absorbed and used by the body for energy. They are calculated by taking the total number of carbohydrates and subtracting any fibre and sugar alcohols, which are not fully absorbed by the body.
Net carbs are crucial on the keto diet because they directly affect ketosis. By limiting net carbs to 20-50 grams per day, individuals can stay in ketosis and burn fat for fuel. Net carbs include simple carbs like glucose, fructose, and lactose, complex carbs like dextrin and cellobiose, and starches, which are chains of glucose.
While total carbs refer to all carbohydrates, including fibre and sugar alcohols, net carbs are more specific. Net carbs are what's left after subtracting fibre and sugar alcohols from the total carbohydrates. This distinction is important because it allows keto dieters to enjoy nutrient-dense, fibre-rich foods without disrupting ketosis.
For example, an avocado may seem high in total carbohydrates, with 11.7 grams. But when you subtract the 9.2 grams of fibre, you're left with only 2.5 grams of net carbs—well within the keto-approved range. This calculation method ensures that keto dieters can still include plenty of healthy, fibrous vegetables in their diet without worrying about exceeding their carb limit.
In addition to helping with weight loss, focusing on net carbs instead of total carbs can provide several health benefits. Net carbs can help with blood sugar control, reduce inflammation, and lower the risk of heart disease. It's important to note that not all fibre and sugar alcohols are created equal, and some may still impact blood sugar levels. For example, sugar alcohols like maltitol and sorbitol can increase blood sugar, although not to the same extent as real sugar.
In conclusion, net carbs are the only carbs that count on keto. By tracking net carbs instead of total carbs, individuals can effectively manage their carb intake, stay in ketosis, and enjoy the benefits of the keto diet.

Total carbs include all types of carbohydrates
The total carb count on a food label refers to the sum of all three types of carbohydrates. Total carbs are significant because they provide the body with energy. They are converted into glucose, or blood sugar, which serves as fuel for the body's cells, tissues, and organs. Glucose can be used immediately or stored in the liver and muscles for later.
While total carbs are essential, net carbs are the primary focus of the keto diet. Net carbs refer to the carbohydrates that are absorbed and utilised by the body for energy. Fiber and sugar alcohols, which are not fully absorbed by the body, are excluded from net carb calculations.
The keto diet is a low-carb, high-fat diet that aims to induce ketosis, a state where the body uses fat instead of glucose as its primary energy source. By limiting net carbs to 20-50 grams per day, individuals on the keto diet can achieve and maintain ketosis.
In summary, while total carbs include all types of carbohydrates, net carbs are the key metric for keto dieters. Understanding the difference between these two concepts is crucial for effectively managing carbohydrate intake and achieving one's keto diet goals.

Net carbs are carbs that raise your blood sugar
Net carbs are carbohydrates that enter the bloodstream and raise your blood sugar. Carbohydrates are broken down into glucose, which is a type of sugar, and this raises the level of glucose in your blood. This is what is commonly referred to as "blood sugar".
There are three main types of carbohydrates in food: starches, sugars, and fiber. The term "total carbohydrates" refers to all three of these types. When you eat or drink foods that contain carbohydrates, your body breaks them down into glucose, which then raises your blood sugar level.
Net carbs are the number of carbohydrates absorbed into your body. Some sources of carbohydrates, like fiber and sugar alcohols, are not absorbed into your bloodstream and therefore are not counted in your daily allowance of net carbs. Net carbs are determined by removing fiber and sugar alcohols from the total carbohydrates count.
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. The keto diet focuses on net carbs, which are the ones that are absorbed into your body. By focusing on net carbs, you can still give your body the essential fiber it needs for proper function.
On the keto diet, you are allowed to have no more than 20-50 grams of net carbs per day. To calculate the net carbs in a food, you can follow these steps:
- Determine the total amount of carbohydrates in a food by checking the nutrition label.
- Determine the amount of fiber in the food.
- Subtract the amount of fiber from the total amount of carbohydrates. The result is the net carb count.
For example, if a certain food has 20 grams of total carbohydrates and 8 grams of fiber, the net carb count would be 12 grams (20 grams of total carbs - 8 grams of fiber = 12 grams of net carbs).

Net carbs can be calculated by subtracting fibre and sugar alcohols from total carbs
Net carbs are the amount of carbohydrates in a food that can be absorbed and used by the body for energy. To calculate net carbs, subtract the amount of fibre and sugar alcohols from the total amount of carbohydrates.
The formula for calculating net carbs is:
> Net Carbs = Total Carbs - Fibre - Sugar Alcohols
For example, if a food contains 20 grams of total carbohydrates, 10 grams of fibre, and 5 grams of sugar alcohols, the calculation would be:
20 grams - 10 grams - 5 grams = 5 grams of net carbs.
It's important to note that not all sugar alcohols are treated equally in this calculation. Erythritol, for instance, can be completely subtracted from the total amount of carbohydrates, whereas other sugar alcohols are only partially absorbed and should be halved before being subtracted. So, for a product containing 10 grams of any sugar alcohol other than erythritol, you would subtract 5 grams from the total amount of carbohydrates to get the net carbs.
Additionally, the calculation for net carbs may vary depending on the region. In the United States, total carbohydrates include fibre and sugar alcohols, so these need to be subtracted to find net carbs. However, in some other countries, like Australia and Europe, the total carbohydrates listed on food labels may already exclude fibre, so the calculation would be different. Always check the specific guidelines for your region when calculating net carbs.

Net carbs are a reflection of the glycemic index of foods
The keto diet is a low-carb, high-fat diet. The diet involves taking a very low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes. On the keto diet, net carbs are the only carbs that count. Net carbs are all the carbohydrates in food that can be absorbed and used by the body for energy.
Net carbs are determined by removing fiber and sugar alcohols from the total carbohydrates count. Fiber and sugar alcohols are not counted as net carbs because they are not digested like other carbohydrates. Instead of breaking down into glucose, they pass intact into the colon. Net carbs can be calculated by taking the total carbohydrates as indicated on the food label and subtracting the dietary fiber and sugar alcohol content.
The Glycemic Index is a way of ranking carbohydrate-containing foods based on how slowly or quickly they are digested and increase blood glucose levels over a period of time, usually 2 hours. Carbohydrates that break down quickly during digestion have a higher glycemic index. These high-GI carbohydrates, such as a baked potato, release their glucose into the blood quickly. Carbohydrates that break down slowly, such as oats, release glucose gradually into the bloodstream. They have low glycemic indexes. The blood glucose response is slower and flatter, and low-GI foods prolong digestion due to their slow breakdown.
The Glycemic Index can be a useful tool for choosing foods and drinks consistent with a healthy diet. It is important to note that the amount of carbohydrate-containing food eaten also affects blood glucose levels. For example, even though pasta has a low GI, a large serving can still cause blood glucose levels to rise more rapidly than a smaller serving. This is called the glycemic load (GL), which considers both the GI of the food and the amount of carbohydrate in a portion.
