Understanding Net Carbs: The Key To Keto Success

The keto diet is a low-carb, high-fat diet that aims to get and keep the body in a state of ketosis, where it burns fat for energy instead of carbohydrates. Net carbs refer to the total number of carbohydrates in a food item minus the indigestible carbs, such as fibre and sugar alcohols. Net carbs are important to track on a keto diet because they are the carbs that impact blood sugar levels and can kick the body out of ketosis. While there is no official definition of net carbs, they can be calculated by subtracting the fibre and sugar alcohol content from the total carbohydrates in a food item.

Net carbs are the carbs that impact blood sugar levels

Net carbs are the total grams of carbohydrates in a food item minus the grams of dietary fibre and certain sugar alcohols. These are the only carbs that matter on a keto diet because they are the carbs that impact your blood sugar levels.

To calculate net carbs, take a food's total carbs and subtract its fibre content and sugar alcohols. For example, half an avocado contains 9 grams of total carbs, 7 grams of fibre, and zero sugar alcohols. Subtract the fibre (7 grams) from the total carbohydrates (9 grams), and you're left with 2 grams of net carbs.

Some sugar alcohols, such as erythritol, have a minimal impact on blood glucose and insulin levels and can be subtracted from the total carb count. However, certain sugar alcohols, such as maltitol, do impact blood sugar levels and should be counted in your net carbs.

The three main categories of net carbs are simple carbs (glucose, fructose, lactose), complex carbs (dextrin and cellobiose), and starches (chains of glucose). Foods that are high in net carbs include pasta, bread, grains, certain fruits, starchy vegetables, and table sugar.

On a keto diet, it is important to keep net carbs low—under about 50 grams per day—to stay in ketosis, a state in which the body shifts from burning glucose to burning fat for energy.

Total carbs include indigestible fibre and sugar alcohols

Total carbs refer to the total number of carbohydrates in a food item, including starches, dietary fibre, sugars, and sugar alcohols. However, when following a keto diet, it is crucial to understand the concept of net carbs, which are calculated by subtracting indigestible fibre and sugar alcohols from the total carbohydrates. This distinction is essential because net carbs are the ones that truly impact your blood sugar levels and can potentially kick you out of ketosis, compromising the effectiveness of the keto diet.

Indigestible fibre, also known as insoluble fibre, is a type of carbohydrate that the human body cannot fully digest. Instead of being broken down and absorbed, it passes through the digestive system relatively unchanged. Fibre is found in whole grains, fruits, vegetables, and other plant-based foods. By subtracting the fibre content from the total carbohydrates, you get a more accurate picture of the carbs that will affect your blood sugar on a keto diet.

Sugar alcohols, such as xylitol, erythritol, mannitol, and sorbitol, are another type of carbohydrate that is only partially digested and absorbed. They are commonly used as artificial sweeteners and have a sweet taste, but their molecular structure differs slightly from that of sugar molecules, making them largely indigestible. While most sugar alcohols have a minimal impact on blood sugar, it's important to note that certain types, like maltitol, can affect blood sugar levels. Therefore, it is crucial to consider the specific type of sugar alcohol when calculating net carbs.

The calculation of net carbs is relatively straightforward: you simply subtract the fibre and sugar alcohol content from the total carbohydrates listed on a food label. This calculation is essential for anyone following a keto diet because it helps them stay within their daily carb limit and maintain ketosis. By focusing on net carbs, individuals can make more informed choices about the types and amounts of food they consume while still enjoying a wider range of food options.

However, it is worth mentioning that the concept of net carbs is not without controversy. There is no official definition or standard for net carbs, and food manufacturers may use this term loosely to make their products more appealing to consumers. Additionally, the impact of sugar alcohols on blood sugar and the body is not fully understood, and they may cause gastrointestinal issues in some individuals. Therefore, it is always advisable to read food labels carefully, monitor your blood sugar levels, and consult with a healthcare professional or dietitian before starting any new diet.

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 the indigestible carbohydrates, such as fibre and sugar alcohols. Fibre is a type of carb that the body cannot digest due to a lack of enzymes to break it down, so it simply passes through the body unchanged. Sugar alcohols, such as xylitol and erythritol, are also not digestible by the body due to their molecular structure, which differs slightly from that of sugar molecules.

The formula for calculating net carbs is: Net Carbs = Total Carbs – Fibre – Sugar Alcohols. For example, one cup of raspberries contains 15 grams of total carbs, 8 grams of fibre, and no sugar alcohols. Subtracting the fibre from the total carbs gives you 7 grams of net carbs (15 grams total carbs – 8 grams fibre = 7 grams net carbs).

It is important to note that not all sugar alcohols are truly carb-free, and some may impact blood sugar levels. For example, maltitol is a sugar alcohol that does affect blood sugar and should be counted in your net carb count. Additionally, consuming large amounts of sugar alcohols may cause gastrointestinal issues such as diarrhoea and bloating.

Calculating net carbs is crucial when following a keto diet because net carbs impact blood sugar levels, which can kick you out of ketosis, the ultimate goal of the keto diet. By limiting net carbs, you can stay within the recommended range of 20-50 grams of net carbs per day to maintain ketosis.

Net carbs are the only carbs that count on keto

Net carbs are the only type of carbs that matter when you're on a keto diet. This is because net carbs are the carbs that can be digested and used for energy, and they are the carbs that impact your blood sugar.

When you're on a keto diet, you want to keep your blood sugar and insulin levels low, so your body enters a state of ketosis. In ketosis, your body burns fat, including body fat, for energy instead of burning glucose. To get into ketosis, you need to restrict your carb intake so that your body starts producing ketones. Net carbs are the number of carbs that matter when it comes to getting into and staying in ketosis.

To calculate net carbs, you take the total carbs in a food and subtract the fibre and sugar alcohols. This is because fibre passes through the digestive system unchanged, as the body doesn't have the enzymes to break it down. Sugar alcohols, such as xylitol and erythritol, also don't count towards net carbs because they have a slightly different molecular structure to sugar molecules, which means they are indigestible.

However, it's important to note that not all sugar alcohols are truly carb-free. Some, like maltitol, do impact blood sugar levels and should be factored into your net carb count, especially if you are eating a large amount or are diabetic.

The formula for calculating net carbs is: Net carbs = total carbs – fibre – sugar alcohols.

For example, one cup of raspberries contains 15 grams of total carbs, 8 grams of fibre, and 0 grams of sugar alcohols. This works out to 7 grams of net carbs (15 grams total carbs – 8 grams fibre – 0 grams sugar alcohols = 7 grams net carbs).

Net carbs are important because they help you stay within your daily carb limit and maintain ketosis. By tracking net carbs, you can include more nutrient-dense foods in your diet, such as avocados, berries, nuts, and low-carb veggies, while still keeping your carb count low.

The impact of sugar alcohols on blood sugar is not fully understood

Net carbs are an important concept for people on the keto diet to understand. Net carbs are the only type of carbohydrates that count on keto because they are the ones that raise your blood sugar and can kick you out of ketosis. To calculate net carbs, you subtract the fibre and sugar alcohols from the total carbohydrates.

Sugar alcohols are a type of carbohydrate that is becoming more popular as a "keto-friendly" sweetener. They are less sweet than sugar but have fewer calories per gram, making them a "low-calorie" sweetener. Sugar alcohols are commonly used in ""sugar-free" foods, including chewing gum, candy, ice cream, and fruit spreads. They are also used as sweeteners in toothpaste, mouthwash, and cough drops.

While sugar alcohols have fewer calories and a less pronounced impact on blood sugar than regular sugar, their impact on blood sugar is not fully understood, and they may cause problems for some people. Sugar alcohols are hard for the body to digest, and eating too many of them may cause digestive issues such as gas, bloating, stomach aches, cramping, and diarrhoea. Some sugar alcohols, such as maltitol, can raise blood sugar levels, and people with diabetes need to be cautious about consuming them.

Overall, while sugar alcohols may be a good alternative to sugar for some people, it is important to understand their potential impact on blood sugar and digestive health.
