When it comes to low-carb diets, particularly the keto diet, understanding the difference between net carbs and total carbs is essential for success. These terms are often used interchangeably, but they represent different ways of counting carbohydrates, which can impact your overall nutrition plan. In this article, we will dive deep into the concept of net carbs and total carbs, their differences, and how each plays a role in your daily carbohydrate intake.
What Are Total Carbs?
Total carbohydrates represent the sum of all types of carbohydrates found in food. This includes starches, sugars, and fiber. When you check the nutrition label, the total carbs value is usually listed as the first carbohydrate figure. However, not all carbohydrates are equal in terms of how they affect your body, which is where the distinction between total carbs and net carbs comes into play.
What Are Net Carbs?
Net carbs refer to the carbohydrates that are actually absorbed by your body and contribute to your blood sugar levels. The calculation of net carbs excludes certain types of carbs that don’t impact blood sugar, such as fiber and sugar alcohols. To calculate net carbs, you subtract fiber and, in some cases, sugar alcohols, from the total carbohydrate count.
The Role of Fiber in Carbohydrates
Fiber is a type of carbohydrate that your body cannot digest. Because fiber doesn’t raise blood sugar levels, it is excluded from the net carb count. There are two types of fiber: soluble and insoluble. Both types are beneficial for digestion and overall health, but only the fiber that is soluble is typically considered when calculating net carbs.
How Sugar Alcohols Factor Into Net Carbs
Sugar alcohols are a form of reduced-calorie sweetener found in many low-carb products. These sweeteners don’t cause the same blood sugar spikes as regular sugar, which is why they are subtracted from total carbs to determine net carbs. However, not all sugar alcohols are created equal. Some, like erythritol, have little to no impact on blood sugar, while others may still contribute a small amount.

Why Are Net Carbs Important on a Keto Diet?
The keto diet focuses on reducing carbohydrate intake to put the body in a state of ketosis, where it burns fat for energy instead of glucose. Since fiber and sugar alcohols don’t affect blood sugar in the same way that digestible carbs do, they don’t interfere with ketosis. Therefore, counting net carbs rather than total carbs is crucial for staying in ketosis.
The Potential Pitfalls of Counting Net Carbs
While counting net carbs is a helpful method for staying in ketosis, it’s not always a perfect system. Some sugar alcohols, like maltitol, can cause digestive distress or raise blood sugar levels more than expected. Additionally, foods labeled as “low-carb” may contain hidden carbs in the form of added sugars or unlisted sugar alcohols, making it important to carefully read nutrition labels.
Total Carbs and Their Impact on Blood Sugar
Unlike net carbs, total carbs represent the full amount of carbohydrate content in a food, including sugars and starches that are absorbed by your body. When you consume total carbs, they are broken down into glucose, which can cause blood sugar levels to rise. This is a crucial consideration for people with diabetes or those following a strict low-carb diet.
Total Carbs and Their Role in Weight Loss
While net carbs are often the focus in low-carb and keto diets, total carbs can still play an important role in weight management. Consuming excessive amounts of total carbs, especially refined carbs like sugar, can lead to weight gain and spikes in insulin levels. It’s important to understand both types of carbs to make informed choices about your diet.
Should You Count Net Carbs or Total Carbs?
Deciding whether to count net carbs or total carbs largely depends on your individual health goals. For those following the keto diet or trying to reduce their insulin levels, focusing on net carbs is often the best approach. However, if you’re managing blood sugar or following a more general low-carb diet, total carbs may be a better measure to track.
How to Calculate Net Carbs
To calculate net carbs, simply subtract the fiber (and any sugar alcohols that don’t affect blood sugar) from the total carbohydrate content. For example, if a food contains 10 grams of total carbs and 5 grams of fiber, the net carbs would be 5 grams.

The Importance of Choosing Whole Foods
When tracking your carbs, it’s always best to choose whole, unprocessed foods. Whole vegetables, meats, and other minimally processed foods tend to have a more accurate net carb count and are richer in essential nutrients compared to packaged foods, which may contain hidden sugars or artificial sweeteners.
How Net Carbs Affect Ketosis
Ketosis occurs when the body switches from burning glucose for fuel to burning fat. Net carbs are the key to maintaining this metabolic state. By counting only the digestible carbohydrates, you can keep your carb intake low enough to stay in ketosis and burn fat efficiently.
The Difference in Counting for Diabetes
For individuals with diabetes, managing carbohydrate intake is crucial for controlling blood sugar levels. Total carbs give a fuller picture of how much glucose will enter the bloodstream. On the other hand, net carbs may help reduce the focus on non-impactful carbs like fiber, offering a more nuanced approach to carbohydrate counting.
Misleading Labels: Understanding Carb Counts on Packaged Foods
Many packaged foods, particularly low-carb or keto-friendly products, may present net carbs in bold, but it’s important to verify that the subtraction of fiber and sugar alcohols is accurate. Some products may overestimate their net carb content, misleading consumers into thinking they’re within their carb limits.
How the Body Processes Carbs
Understanding how the body processes carbs is fundamental to both net and total carb counting. When you consume carbohydrates, they are broken down into glucose, which enters the bloodstream. The presence of fiber and sugar alcohols means that not all carbs contribute to a glucose spike, making it possible to consume more carbs without impacting ketosis.
The Science Behind Net Carbs
The concept of net carbs comes from the fact that certain carbohydrates, such as fiber, pass through the digestive system largely undigested. Sugar alcohols also have a minimal impact on blood sugar, making them ideal for low-carb diets. This is why subtracting them from the total carb count provides a more accurate representation of how many carbs will affect your body.
The Impact of Fiber on Gut Health
Fiber is essential for good digestion and gut health. While it doesn’t contribute to net carbs, it plays a critical role in regulating bowel movements, lowering cholesterol, and supporting overall digestive health. This is why, even when counting net carbs, it’s crucial to get an adequate amount of fiber from your diet.
Popular Low-Carb Diets and Their Carb Counting Methods
Different low-carb diets use varying methods of carb counting. The keto diet, for example, emphasizes net carbs to keep insulin levels low and encourage ketosis. Other diets, like the Atkins Diet, may be more flexible in how they approach total carbs versus net carbs. Understanding each approach can help you tailor your carb-counting strategy to suit your needs.
Choosing the Right Carb Count for Your Lifestyle
Ultimately, whether you count total carbs or net carbs comes down to your personal health goals. If you’re focused on managing blood sugar or following a strict keto diet, net carbs are the way to go. However, if you’re looking for a general reduction in carb intake, total carbs may be more appropriate for tracking your progress.
Conclusion: Finding Balance in Your Carb Intake
Understanding the difference between net carbs and total carbs can be the key to achieving your health and dietary goals. By learning how to calculate net carbs and the role they play in your body, you can make more informed decisions about what to eat. Whether you’re following a keto diet, managing diabetes, or just looking to reduce your carb intake, understanding how carbs affect your body is crucial to your success.
