Keto And Net Carbs: What's The Real Deal?

The keto diet is a low-carb, high-fat diet that puts the body into a state of ketosis. To stay in ketosis, a person needs to consume no more than 50 grams of carbs per day. This includes net carbs, which are the carbs that are absorbed into the body. Net carbs are calculated by subtracting fibre and sugar alcohols from the total carbohydrates. Net carbs are an important consideration for keto dieters as they provide flexibility in daily carb intake and help manage weight loss.

Net carbs are the carbs absorbed into your body

Net carbs refer to the carbohydrates in food that can be digested and absorbed by the body. They are also known as digestible or impact carbs. Net carbs are calculated by subtracting the fibre content and, in some cases, sugar alcohols, from the total number of carbohydrates in a food product.

The body breaks down carbohydrates into individual sugar units, which are then absorbed. However, some carbs, such as fibre and sugar alcohols, cannot be broken down into individual sugars and are therefore not absorbed. Fibre passes through the body undigested and has no impact on blood sugar or insulin levels. Sugar alcohols, on the other hand, may be partially absorbed and can have varying effects on blood sugar and insulin levels.

Calculating net carbs can be confusing due to conflicting and outdated information, as well as a lack of standard definitions. The Food and Drug Administration (FDA) does not recognise the term "net carbs" and recommends using the total carbohydrates listed on nutrition labels.

When following a keto or low-carb diet, tracking net carbs is essential to staying within the strict carbohydrate limits. Net carbs are particularly important for people with diabetes, as their bodies cannot produce enough insulin to maintain safe blood sugar levels.

By keeping net carbs low, typically under 50 grams per day, the body enters a state of ketosis, where it shifts from burning glucose to burning fat for energy. This is a key principle of the keto diet, which emphasises high-fat, low-carbohydrate intake.

In summary, net carbs represent the digestible portion of carbohydrates that are absorbed by the body and impact blood sugar levels. Accurate calculation and monitoring of net carbs are crucial for individuals following keto or low-carb diets, especially those with diabetes or prediabetes.

Total carbs include natural sugars, starches, fibre, and sugar alcohols

Total carbohydrates refer to the number of carbs from all sources, including natural sugars, starches, fibre, and sugar alcohols. Natural sugars are those found in milk or fruit, while added sugars are those added during processing, such as in canned fruit or cookies. Starches, also known as complex carbohydrates, are found in starchy vegetables like peas, corn, beans, and potatoes, as well as grains like oats, barley, and rice. Fibre is a type of carbohydrate that the body cannot fully digest, and it is found in plant foods like fruits, vegetables, whole grains, nuts, and legumes. Sugar alcohols, such as xylitol and erythritol, are derived from plant sources and generally do not impact blood sugar levels.

When reading a standard nutrition label, the total carbohydrate count includes all these components. For example, a food label might list the total carbohydrates as 37 grams, which includes sugar, fibre, and sometimes sugar alcohols. Net carbs, on the other hand, refer to the total carbohydrates minus the fibre. So, if a food has 37 grams of total carbs and 4 grams of fibre, the net carb count would be 33 grams. Net carbs are the carbs that are absorbed by the body and can impact blood sugar levels.

When following a keto diet, it is important to consider the number of net carbs in foods. To stay in ketosis, a person should consume up to 50 grams of carbs per day. This involves eating high levels of fats and very low levels of carbohydrates. Net carbs are calculated by subtracting the amount of fibre from the total number of carbs. If the food is processed, half of the sugar alcohol content should also be subtracted. For example, a medium avocado contains 17.1 grams of total carbs, 13.5 grams of which is fibre. So, the net carbs for the avocado would be 3.6 grams (17.1 grams total carbs - 13.5 grams fibre).

While total carbs include natural sugars, starches, fibre, and sugar alcohols, net carbs are calculated by subtracting the fibre and sometimes sugar alcohol content from the total carb count. This distinction is important for those following a keto diet, as it helps them monitor their carb intake to stay within the recommended range for ketosis.

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

Net carbs refer to the amount of carbohydrates that are absorbed and digested by your body. They are also referred to as digestible or impact carbs. Net carbs can be calculated by subtracting fibre and sugar alcohols from the total number of carbs.

Fibre is a type of complex carb that cannot be broken down by the enzymes in the small intestine and therefore cannot be absorbed by the body. It passes directly into the colon and then out of the body. Fibre is usually included on food labels under the total carbohydrate count. To calculate net carbs, subtract the fibre content from the total carbs. For example, if a food contains 20 grams of total carbs and 10 grams of fibre, it has 10 grams of net carbs.

Sugar alcohols are often added to low-carb foods to make them sweeter. The body processes sugar alcohols in a similar way to fibre, but not all sugar alcohols are the same. Erythritol, for instance, is usually not digested by the body at all and can be completely subtracted from the total carbs. Other sugar alcohols, like maltitol and sorbitol, do affect blood sugar levels and are partially digested, so only half of their total grams can be subtracted from the total carbs.

To calculate net carbs in whole foods, simply subtract the fibre content from the total carbs. For processed foods, it is also necessary to subtract half the sugar alcohol content from the total carbs listed on the nutrition label. For example, if a food contains 20 grams of total carbs, 10 grams of fibre, and 10 grams of sugar alcohols, subtract 10 grams of fibre and 5 grams of sugar alcohols (half of the total) from the total carbs, leaving 5 grams of net carbs.

Calculating net carbs can be beneficial for people with diabetes, as it helps them to determine how much insulin they need. It can also be helpful for people trying to lose weight or improve their health by tracking their carbohydrate intake. However, it is important to note that the Food and Drug Administration (FDA) does not recognise the term "net carbs" and recommends using the total carbohydrates listed on nutrition labels.

Net carbs are a reflection of the glycemic index of foods

The keto diet is a low-carb, high-fat diet that puts the body into a state of ketosis. To stay in ketosis, a person can consume up to 50 grams of carbs per day. However, net carbs are the carbs that are absorbed by the body and impact blood sugar levels. Net carbs are calculated by subtracting the amount of fibre and sugar alcohol from the total number of carbs.

Net carbs are indeed a reflection of the glycemic index of foods. The glycemic index (GI) is a tool that measures how much a food boosts blood sugar levels, specifically glucose levels in the blood. The GI rates foods on a scale of 1-100 by comparing the effect of consuming a specific amount of a particular food on blood sugar with the same amount of pure glucose. A food with a glycemic index of 28 boosts blood sugar only 28% as much as pure glucose, while a food with a GI of 95 acts like pure glucose.

High-glycemic foods result in a rapid increase in insulin and blood sugar levels, while low-glycemic foods have a slower and smaller effect. Low-glycemic foods include most fruits and vegetables, beans, minimally processed grains, pasta, low-fat dairy, and nuts. On the other hand, high-glycemic foods include white bread, rice cakes, crackers, bagels, cakes, doughnuts, croissants, and packaged breakfast cereals.

The glycemic index is an important consideration when choosing foods, especially for individuals with diabetes or impaired glucose tolerance. For example, porridge made from whole-grain oats is a better choice than cornflakes for breakfast as it is digested more slowly, resulting in a slower rise in blood glucose levels.

In summary, net carbs are a reflection of the glycemic index as they both indicate the impact of food on blood sugar levels. The glycemic index provides a quantitative measure by ranking foods based on their effect on blood glucose, while net carbs give an estimate of the number of carbohydrates that will impact blood sugar after consuming a particular food.

Tracking net carbs may be more sustainable than counting total carbs

Tracking Net Carbs vs Total Carbs: Which is More Sustainable?

When starting a keto diet, you will likely hear a lot about carb counts, macros, and net carbs. This article will explore the difference between net and total carbs and discuss why tracking net carbs may be more sustainable than counting total carbs.

The Difference Between Net and Total Carbs

When reading a standard nutrition label, the total carbohydrate count includes all sources of carbohydrates, such as sugar, fiber, and sometimes sugar alcohols. Net carbs, on the other hand, refer to the total number of carbohydrates minus the fiber. In other words, net carbs = total carbs - fiber.

Benefits of Tracking Net Carbs

There are a few advantages to focusing on net carbs instead of total carbs. Firstly, net carbs give you an idea of how a particular food might impact your blood sugar levels. This is because not all carbs are equally absorbed by the body, and fiber, being a nondigestible carbohydrate, is not absorbed and therefore does not impact blood sugar like other carbohydrates.

Additionally, tracking net carbs can help you make better food choices. For example, a slice of bread and a cup of raspberries may have the same number of total carbs, but the raspberries will keep you fuller and provide more fiber, resulting in a lower net carb count.

Downsides of Focusing on Net Carbs

While tracking net carbs can be beneficial, there are also some downsides to consider. The way individuals process and metabolize "non-impact" carbs like fiber varies, and the formula for calculating net carbs may not accurately reflect this. Additionally, the formula is especially flawed when it comes to packaged foods, as companies may add fiber to their products to decrease the total carb count, which can be misleading.

In conclusion, tracking net carbs can be a more sustainable approach than counting total carbs when following a keto diet. It provides a better understanding of how different foods impact your blood sugar and encourages the consumption of high-fiber foods. However, it is important to be cautious when it comes to packaged foods, as the net carb count may not always be accurate. Ultimately, it is up to the individual to determine their own carb tolerance and find what works best for them.
