The keto diet is a low-carb, high-fat diet that involves taking an extremely low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes. Net carbs are the result of subtracting fibre and sugar alcohols from total carbohydrates. Net carbs are what you're left with after subtracting grams of fibre content and sugar alcohols from the total carbohydrates per serving. Net carbs are a reflection of the glycemic index (GI) of foods, which determines how quickly their carbohydrates are digested and enter the bloodstream.
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, resulting in sustained energy levels.

Net carbs are the result of subtracting fibre and sugar alcohols from total carbohydrates
Net carbs are calculated by subtracting fibre and sugar alcohols from total carbohydrates. This is because fibre and sugar alcohols are not digested or absorbed by the body in the same way as other carbohydrates.
Fibre is a type of carbohydrate that cannot be broken down into individual sugar units by the enzymes in the digestive tract. Instead, it passes directly into the colon, where it can help prevent constipation and lower blood sugar and insulin levels.
Sugar alcohols, on the other hand, are only partially absorbed into the bloodstream and then excreted in urine. They also have a minimal effect on blood sugar and insulin levels.
When calculating net carbs, it is important to note that not all fibre and sugar alcohols are created equal. For example, insoluble fibre does not dissolve in water and is not broken down by the body, while soluble fibre can be partially digested. Similarly, different types of sugar alcohols are absorbed to varying degrees by the small intestine.
Therefore, when calculating net carbs, it is crucial to consider the specific types of fibre and sugar alcohols present in a food item and make adjustments accordingly. This can be done by referring to reputable sources that provide complete nutrition information, such as the USDA Food Composition Databases.
Additionally, it is worth mentioning that the concept of net carbs is controversial within the nutrition community. The Food and Drug Administration (FDA), for instance, does not recognise the term "net carbs" and recommends using total carbohydrates listed on nutrition labels. Despite this, understanding how to calculate net carbs can be beneficial for those following a ketogenic diet, as it allows for a more precise tracking of carbohydrate intake.

Net carbs are a reflection of the glycemic index of foods
Net carbs are calculated by subtracting dietary fibre and sugar alcohols from total carbohydrates. The calculation helps to evaluate the net effect a food has on blood sugar. However, the formula assumes that fibre is not absorbed and sugar alcohols are not a source of sugar, which may not always be accurate.
When following a keto diet, it is important to limit net carbs to 20 grams or fewer per day, or 5 to 10% of calories. This ensures the body enters a state of ketosis, where it burns fat for fuel instead of carbohydrates.
Some examples of foods that are suitable for a keto diet include:
- Animal proteins such as fish, shellfish, meat, and poultry
- Dairy products like cheese, plain Greek yoghurt, and cottage cheese
- Eggs
- Nuts and seeds
- Green leafy vegetables
- Avocados and olives
- Shirataki noodles
- Dark chocolate and cocoa powder
- Unsweetened coffee and tea
- Unsweetened sparkling water
By choosing foods with lower net carbs and following the keto diet guidelines, individuals can effectively manage their blood sugar and weight while enjoying a variety of nutritious and tasty foods.

Net carbs are essential to a keto diet because they directly affect ketosis
Net carbs are the total grams of carbohydrates in any given food minus its grams of dietary fibre and certain sugar alcohols. Dietary fibre is the portion of carbohydrate in plant foods that isn't broken down and absorbed by your digestive tract. Instead, it passes through your system until it reaches your colon, where it is either fermented by bacteria or eliminated in faeces.
The keto diet typically limits carbs to 20-50 grams per day. Net carbs are the ones that are absorbed into your body. Some sources of carbohydrates like fibre and sugar alcohols are not absorbed into your bloodstream, so they are not part of your daily allowance of net carbs. On the keto diet, you are allowed to have no more than 50 grams of net carbs per day.
The fewer net carbs you eat, the more effective the diet appears to be for reaching ketosis, losing weight, or improving type 2 diabetes. Net carbs are essential to a keto diet because they directly affect ketosis. The fewer net carbs you eat, the more effective the diet is for reaching ketosis.

Tracking Net Carbs: Effectively Managing Your Carb Intake
Tracking net carbs is a valuable tool for those following a low-carb diet, such as the ketogenic diet. Net carbs refer to the carbohydrates that are absorbed by your body and significantly impact your blood sugar levels. By monitoring your net carb intake, you can make more informed food choices and stay within your desired carb range. This is especially useful for individuals with specific health goals, such as weight loss or blood sugar management.
Understanding Net Carbs
The term "net carbs" is used to describe the digestible or impact carbs that your body can absorb. This includes both simple carbs, found in foods like fruits and milk, and complex carbs, found in grains and starchy vegetables. When you consume carb-containing foods, enzymes in your small intestine break down most of the carbs into individual sugar units that your body can absorb.
However, some carbs, like fiber and sugar alcohols, are not fully broken down or absorbed. Fiber, for instance, passes directly into the colon and can help prevent constipation without impacting blood sugar or insulin levels. Sugar alcohols, on the other hand, are only partially absorbed and can have varying effects on blood sugar and insulin levels, although generally lower than sugar.
Calculating Net Carbs
To calculate net carbs for whole foods, you simply subtract the fiber content from the total number of carbs. For example, if a medium avocado contains 17.1 grams of total carbs and 13.5 grams of fiber, its net carb content is 3.6 grams.
For processed foods, the calculation is a bit more complex. The general rule is to subtract half of the carbs from sugar alcohols from the total carbs listed on the nutrition label. Erythritol, a type of sugar alcohol, is an exception—if it's the only sugar alcohol in the ingredients, you can subtract its carb content entirely.
Benefits of Tracking Net Carbs
Tracking net carbs can be advantageous for several reasons. Firstly, it provides flexibility within a restrictive low-carb diet. By taking into account the carbs that are not fully absorbed, you can make more food choices while still managing your overall carb intake effectively.
Secondly, tracking net carbs can help you make informed decisions about the types of carbs you consume. For instance, you may opt for foods with higher levels of fiber, which can promote better digestive health and make you feel fuller for longer. Additionally, understanding how your body processes different types of carbs can empower you to manage your blood sugar and overall health more effectively.
Implementing Net Carb Tracking
Many mobile apps now offer net carb tracking features, often as part of a premium subscription. These apps allow you to set net carb goals and monitor your intake, helping you stay on track with your low-carb diet. You can also calculate net carbs manually using the formulas provided earlier.
In conclusion, tracking net carbs is a valuable tool for managing your carb intake effectively, especially on a low-carb diet like keto. It provides flexibility, helps you make informed food choices, and enables you to better manage your health and fitness goals.

Net carbs can provide a more balanced approach to metabolic health
Net carbs can help individuals manage their blood sugar levels, especially those with diabetes. Fibre and certain sugar alcohols, which are subtracted from the total carb count, have a minimal impact on blood sugar. This is important for people with diabetes, as they need to closely monitor their carb intake to keep blood sugar levels within a safe range. By focusing on net carbs, individuals can make food choices that support stable blood sugar levels and may reduce the risk of insulin resistance and type 2 diabetes.
Additionally, net carbs can promote a healthier lifestyle and weight management. Foods with lower net carb content tend to be higher in fibre and lower in added sugars. These foods include whole, nutrient-dense options like vegetables, nuts, seeds, and certain fruits. Prioritising these foods can provide essential vitamins, minerals, and antioxidants, while also promoting satiety and supporting weight management efforts.
Furthermore, net carbs can increase food choices for those on low-carb diets. By subtracting fibre and certain sugar alcohols from the total carb count, individuals can include a broader range of foods, such as non-starchy vegetables, nuts, and seeds, without significantly impacting their net carb intake. This can make it easier to adhere to a low-carb diet and promote a more balanced and nutritious approach to metabolic health.
However, it is important to note that counting net carbs may not be effective for everyone. Some individuals with diabetes may find that focusing solely on net carbs is not sufficient for blood sugar control. Additionally, variations in food labels and discrepancies in net carb calculations can be misleading. Therefore, it is essential to work with a healthcare professional or registered dietitian to determine the best approach for one's metabolic health.
