Keto Diet: Fiber Carbs And Their Role

The ketogenic diet is a low-carb, high-fat diet that puts the body into a metabolic state called ketosis, where fat is burned for energy instead of carbohydrates. When following a keto diet, it is important to understand the difference between net carbs and total carbs. Net carbs refer to the total number of carbohydrates in a food minus the fibre content, while total carbs include all sources of carbohydrates, including sugar, fibre, and sometimes sugar alcohols.

There is some debate about whether net carbs or total carbs are more important to track when following a keto diet. Some experts argue that only net carbs matter, as fibre is not digested by the body and does not impact blood sugar levels. On the other hand, others claim that total carbs are more accurate because gut bacteria can extract energy from fibre, and it is difficult to know exactly how much fibre will be digested. Ultimately, it may depend on individual goals and physiology, as well as the specific guidelines in different countries.

Keto is a low-carb, high-fat diet

The keto diet is a low-carb, high-fat diet. It involves drastically reducing your carbohydrate intake and replacing it with fat. This puts your body into a metabolic state called ketosis, which makes your body more efficient at burning fat for energy.

When following a keto diet, it's important to understand the difference between net carbs and total carbs. Net carbs refer to the total number of carbohydrates in a food minus its grams of total fiber. Fiber is a type of carbohydrate that the body cannot digest, so it doesn't count towards the amount of carbs that can trigger an insulin response. Insulin responses can prevent your body from going into ketosis.

To calculate net carbs, simply subtract the grams of fiber from the total number of carbohydrates. For example, if a food contains 5 grams of total carbohydrates and 2 grams of fiber, the net carb count would be 3 grams.

It's important to note that not all fiber is the same. The fiber found in whole grains, fruits, and vegetables is mostly indigestible and doesn't impact blood sugar levels. On the other hand, processed foods labeled as "low-carb" or "keto-friendly" may still impact blood sugar levels, even if they have a high fiber content. This is because these products may contain ingredients that raise blood sugar, such as dextrose or cane sugar juice.

Additionally, sugar alcohols, which are commonly used as artificial sweeteners, can also impact blood sugar levels. Some sugar alcohols, such as maltitol and sorbitol, have a higher glycemic index and should be factored into your keto carb count.

While following a keto diet, it's recommended to aim for between 20 to 50 grams of net carbs per day. However, this number may vary depending on your activity level and lifestyle. For example, highly active individuals may benefit from a slightly higher carb intake, while those who are sedentary may need to stay on the lower end of the spectrum.

In conclusion, when following a keto diet, it's crucial to focus on net carbs rather than total carbs. This involves subtracting the fiber content from the total carbohydrate count. By doing so, you can ensure that you stay within your carb limit and maintain nutritional ketosis.

Net carbs = total carbs – fibre

The ketogenic diet is a low-carbohydrate method of eating. When you switch to eating a ketogenic diet, you will need to keep your macronutrients, or 'macros', within a certain range. Macros are just a fancy word for the three nutrients the human body needs in the largest quantity: protein, fat, and carbohydrates (or carbs for short).

On a ketogenic diet, you're getting about 70-80% of your calories from fat, 20-25% from protein, and 5-10% from carbs. This is why there is a large focus on tracking your carbohydrate intake. Coming from a standard diet, you're greatly reducing your carb intake, and unless you track, it can be easy to overeat this macronutrient at the beginning.

The most important thing to keep in mind when trying to understand the ketogenic diet is that it's specifically net carbs that are counted when calculating your daily intake. Net carbs are the grams of total carbohydrates in a food minus its grams of total fibre. Fibre is a carbohydrate that your body can't digest, so it doesn't count towards the amount of carbs that can trigger an insulin response, which too much of can prevent your body from going into the ketosis state.

Most keto diets have you aiming for between 20 to 50 grams of net carbs a day. You can easily take a look at the nutrition label of the food you're eating or find the nutrition facts online to quickly calculate the amount of net carbs it contains.

Take cauliflower, for example. One cup of cooked florets contains 5 grams of total carbohydrates. It contains 2 grams of fibre, however, which can be subtracted from the total to achieve 3 grams of net carbs.

It's important to note that there is no official definition of net carbs. This means the way companies calculate their totals can differ.

While the total carbohydrate content of a food may seem high, subtracting fibre and certain sugar alcohols gives you the net carbs. These are the carbs that affect blood sugar levels. This distinction is crucial for staying in ketosis.

Fibre is a type of carb that the body can't digest

Fibre is a type of carbohydrate that the human body cannot digest. Unlike most carbohydrates, fibre cannot be broken down into sugar molecules and, instead, passes through the body undigested. This means that fibre does not affect blood sugar levels.

There are two types of fibre: soluble and insoluble. Soluble fibre dissolves in water and can help lower glucose and cholesterol levels in the blood. Insoluble fibre does not dissolve in water but can help food move through the digestive system, preventing constipation.

The body needs at least 25 to 35 grams of fibre per day for good health. However, most people only get about half that amount. Fibre can be found in whole grains, fruits, vegetables, legumes, and nuts.

When counting carbohydrates, some people subtract the grams of fibre from the total carbohydrate count. This is known as counting "net carbs". However, others argue that it is better to count "total carbs" since the amount of fibre listed on nutrition labels may not always be correct, and gut bacteria can extract energy from fibre.

Ultimately, the decision to count net or total carbs depends on individual goals and physiology. Those with diabetes, for example, may be better off counting total carbs, as fibre may still influence their blood sugar levels.

Sugar alcohols are also subtracted from total carbs

Sugar alcohols are sugar substitutes that are commonly used in food products labelled as "sugar-free". They are often used as an alternative to table sugar because they are sweet-tasting but can be listed as having "no sugar added" on the packaging.

Sugar alcohols are neither sugar nor alcohol but a hybrid that creates a whole new type of carbohydrate compound. They are derived from plant sources and are commonly used as artificial sweeteners. Sugar alcohols include xylitol, erythritol, mannitol, and sorbitol.

Sugar alcohols are only partially digested and absorbed by the body. They are broken down in the small intestine and the remnants that are not digested are passed on to the large intestine. This breakdown process can lead to gastrointestinal disturbances such as diarrhoea, gas, stomach cramps, and bloating.

Sugar alcohols are usually not counted towards the total carbohydrate count because they are thought to have a minimal impact on blood sugar levels. However, some sugar alcohols, such as maltitol and sorbitol, can cause a blood glucose response and may need to be counted towards the total carbohydrate count.

The general formula for calculating net carbs is: Net carbs = total carbs - fiber - sugar alcohols. However, it is important to note that not all sugar alcohols are created equal and some may need to be included in the total carb count.

When it comes to the keto diet, opinions vary on whether to subtract sugar alcohols from the total carb count. Some people choose to subtract all sugar alcohols, while others only subtract certain types such as erythritol. Ultimately, it depends on the individual's goals and physiology, as well as the type of sweetener being used.

Keto is used to treat diabetes, epilepsy, autoimmune disorders, acid reflux, inflammation, and hormonal imbalances

The ketogenic diet is a low-carb, high-fat diet that has been used to treat a variety of health conditions, including diabetes, epilepsy, autoimmune disorders, acid reflux, inflammation, and hormonal imbalances. While the diet has been shown to be effective in managing these conditions, there are also some potential drawbacks and side effects that should be considered.

Diabetes

The ketogenic diet can be an effective way to manage blood glucose levels in people with Type 2 diabetes or prediabetes. A study by Stanford Medicine researchers compared the ketogenic diet to the Mediterranean diet, another low-carb diet, and found that both diets were similarly effective in controlling blood glucose and aiding weight loss. However, the ketogenic diet was more restrictive and difficult to follow, and it provided less fiber and certain vitamins and minerals. Overall, the Mediterranean diet was found to be a less restrictive and more sustainable way to manage diabetes while still providing the benefits of a low-carb diet.

Epilepsy

The ketogenic diet has been used as an alternative treatment for epilepsy, particularly in children. The diet works by changing the way the body turns food into energy, reducing carbohydrates and increasing the consumption of proteins and fats. This shift in energy sources can help to reduce seizures and improve symptoms in people with epilepsy. However, it is important to note that the ketogenic diet should be used under the supervision of a healthcare professional, especially in the case of children.

Autoimmune Disorders

The ketogenic diet has been studied for its potential benefits in treating autoimmune disorders such as lupus and multiple sclerosis (MS). The diet's anti-inflammatory properties are believed to play a key role in reducing inflammation and calming an overactive immune system. A mouse study by researchers at UC San Francisco found that the ketogenic diet increased the production of anti-inflammatory compounds and improved symptoms of MS in mice. However, more research is needed to determine the effectiveness of the diet in treating autoimmune disorders in humans.

Acid Reflux

The ketogenic diet may not be ideal for people with acid reflux. Fatty foods, which are a significant component of the ketogenic diet, can cause the lower esophageal sphincter to relax, allowing more stomach acid to back up. Additionally, fat takes longer to leave the stomach, which can further increase acid reflux symptoms. Obesity is a key factor in acid reflux, so weight loss can be beneficial. However, there are other weight loss strategies that may be more effective and less risky for people with acid reflux.

Inflammation and Hormonal Imbalances

The ketogenic diet has been shown to reduce inflammation and improve hormonal imbalances. By changing the body's energy source from carbohydrates to fats, the diet can reduce oxidative stress and sensitivity within the nervous system. Additionally, the production of ketone bodies during the ketogenic diet can have a calming effect on the nervous system, which may help with hormonal imbalances. However, more research is needed to fully understand the mechanisms behind these benefits.
