Keto And Carbs: The Fiber Equation

The keto diet is a low-carb, high-fat diet that involves drastically cutting down on carbohydrates and substituting them with fat to stimulate the body's fat-burning processes. On this diet, net carbs are counted when calculating daily intake, and net carbs are the grams of total carbohydrates in a food minus its grams of total fibre. This is because fibre is a carbohydrate that the body cannot digest, so it doesn't count towards the amount of carbs that can trigger an insulin response, which can prevent the body from going into a state of ketosis.

Net carbs are calculated by subtracting fibre from total carbs

Net carbs are the total amount of digestible carbohydrates in a food product or meal. They are calculated by subtracting the fibre content from the total number of carbohydrates. This is because fibre is a carbohydrate that the body cannot digest.

The formula for calculating net carbs is:

> Total Carbohydrates – Fibre = Net Carbs

For example, a food that contains 20 grams of total carbohydrates and 10 grams of fibre has 10 grams of net carbs. This is the amount of carbohydrates the food contains that the body can digest into glucose.

Some carbohydrates, known as complex carbohydrates, take longer to break down and provide a more lasting source of energy. Fibre is one of these complex carbohydrates and is not broken down by the enzymes in the small intestine, where most carbohydrates are digested. Instead, fibre passes directly into the colon, where its fate depends on its type. There are two types of fibre: insoluble and soluble. Insoluble fibre creates bulkier stools and can help prevent constipation, while soluble fibre is fermented by the colon into short-chain fatty acids, which are important for gut health.

Sugar alcohols, which are often used to add sweetness to low-carb foods, are processed by the body in a similar way to fibre. Erythritol, a sugar alcohol found naturally in fruit and some fermented foods, has a minimal impact on blood sugar levels and is not fully digested by the body. Therefore, the total value of erythritol can be subtracted from the total carbohydrates when calculating net carbs. However, other sugar alcohols, such as maltitol, sorbitol, isomalt, and glycerin, do affect blood sugar levels and are partially digested by the body. As a result, experts recommend dividing their total number of grams per serving in half and subtracting that amount from the total carbohydrates.

Net carbs are particularly important for people following a ketogenic diet, as this is a very low-carb diet that aims to put the body into a state of ketosis, where it burns fat instead of carbohydrates for energy. By subtracting the grams of fibre from the total grams of carbohydrates, individuals on a keto diet can ensure they stay within their carbohydrate target and maintain the state of ketosis.

Fibre is a type of carbohydrate that the body cannot digest

Fibre is a type of carbohydrate that the human body cannot digest. While most carbohydrates are broken down into sugar molecules called glucose, fibre cannot be broken down into these sugar molecules. Instead, it passes through the body undigested. Fibre is, therefore, an essential component of a healthy diet, helping to regulate the body's use of sugars, keeping hunger and blood sugar in check.

Fibre comes in two varieties: soluble and insoluble. Soluble fibre dissolves in water and can help lower glucose levels and blood cholesterol. Foods containing soluble fibre include oatmeal, chia seeds, nuts, beans, lentils, apples, and blueberries. Insoluble fibre does not dissolve in water but can help food move through the digestive system, preventing constipation. Insoluble fibre is found in whole wheat products, quinoa, brown rice, legumes, leafy greens, almonds, walnuts, seeds, and fruits with edible skins like pears and apples.

The body's inability to digest fibre is particularly relevant when it comes to the keto diet. The keto diet is a low-carb, high-fat diet, where the body is put into a metabolic state called ketosis, which makes the body more efficient at burning fat for energy. When calculating daily intake on the keto diet, it is the net carbs (grams of total carbohydrates minus grams of total fibre) that are counted. This is because fibre, as a non-digestible carbohydrate, does not count towards the amount of carbs that can trigger an insulin response, which can prevent the body from going into the ketosis state.

On the keto diet, daily net carb intake is typically restricted to between 20 and 50 grams. This means that high-fibre, low-net-carb foods such as cauliflower are encouraged. For example, one cup of cooked cauliflower contains 5 grams of total carbohydrates, but 2 grams of fibre, resulting in only 3 grams of net carbs.

Net carbs are the only carbs counted in a keto diet

The keto diet is a low-carb, high-fat diet. It involves taking a very low amount of carbohydrates and substituting them with fat to stimulate the body's fat-burning processes. This puts your body into a metabolic state called ketosis, which makes your body more efficient at burning fat for energy.

Net carbs are determined by removing fiber and sugar alcohols from the total carbohydrates count. Sugar alcohols are also subtracted because the body does not fully absorb them.

Total carbs include all carbohydrates present in food, including fiber and sugar alcohols, which are not fully absorbed by the body.

To calculate net carbs, you can follow these steps:

• Determine the total amount of carbohydrates in a food or meal by checking the nutrition label or using a food tracking app.
• Determine the amount of fiber in the food or meal.
• Subtract the amount of fiber from the total amount of carbohydrates. The result is the net carb count.

For example, if a certain type of food has 20 grams of total carbohydrates and 8 grams of fiber, the net carb count would be 12 grams (20 grams of total carbs - 8 grams of fiber = 12 grams of net carbs).

The keto diet is a very low-carb, high-fat diet

On the keto diet, you replace most of your usual carb intake with fat. This puts your body into a metabolic state called ketosis, which makes your body more efficient at burning fat for energy.

The keto diet is different from other low-carb diets in terms of its macronutrient breakdown. It requires you to get 5% to 10% of your calories from carbs, 15% to 30% from protein, and at least 70% to 80% from fat. In contrast, a typical low-carb diet recommends getting 10% to 25% of your calories from carbs, 40% to 50% from protein, and 30% to 40% from fats.

When following the keto diet, it is important to consume foods that are low in carbs and high in healthy fats. This includes:

• Low-carb vegetables such as leafy greens, broccoli, cauliflower, and tomatoes
• Healthy fats such as olive oil, avocado, and nuts
• Protein sources such as meat, poultry, fish, and eggs
• Low-carb fruits such as berries
• Dairy products like cheese, heavy cream, and sour cream

To get into ketosis and stay there, it is recommended to eat less than 20 grams of net carbs per day. Net carbs are calculated by subtracting the grams of fibre from the total grams of carbohydrates in a food. For example, one cup of cooked cauliflower contains 5 grams of total carbohydrates, but only 3 grams of net carbs since it contains 2 grams of fibre.

While the keto diet can be effective for weight loss and certain health conditions, it is important to note that it is very restrictive and may cause side effects, especially when starting out. Some people may also find it challenging to build muscle on the keto diet due to its low protein intake. It is always recommended to consult with a healthcare professional before starting any new diet.

The keto diet originated as a treatment for epilepsy

The keto diet, or ketogenic diet, is a therapeutic diet that was originally used to control seizures in people with epilepsy. It is a high-fat, low-carbohydrate diet that changes the way the brain gets energy to function. The diet has been used to reduce seizures since the 1920s and is usually considered for children with epilepsy when medications have failed to control their seizures. The diet is also harder for adults to maintain due to the restricted food choices.

The keto diet works by putting the body into a metabolic state called ketosis, where fat is burned for energy instead of carbohydrates. In this state, the body uses ketones, which are formed when the body uses fat for energy, as its primary fuel source instead of glucose. Ketones are not dangerous and can be detected in the urine, blood, and breath. While the exact mechanism of how the keto diet helps reduce seizures is not fully understood, it is believed that the low sugar and high-fat components alter the 'excitability' of the brain, reducing the tendency to generate seizures.

The classic keto diet consists of 70% to 80% fats, 20% proteins, and 5% to 10% carbohydrates. It involves carefully measuring and restricting the intake of carbohydrates and replacing them with fat. The diet is typically started in the hospital under the supervision of a neurologist, dietitian, and registered nurse. The patient's nutrition and growth are closely monitored, and they may be given a diary to record the number and type of seizures while on the diet.

The keto diet has proven effective in reducing seizures in many patients with epilepsy. Several studies have shown that the keto diet can reduce or prevent seizures in children whose seizures could not be controlled by medications. About 40% to 50% of children who start the keto diet experience a 50% reduction in seizures, and some children even become seizure-free. The diet has also been shown to have other benefits, such as increased alertness, awareness, and responsiveness.

While the keto diet has been successful in treating seizures, it is not without its risks and side effects. Long-term use of the keto diet may lead to high cholesterol levels and low bone density. Additionally, the restricted nature of the diet may lead to nutritional deficiencies, and it can be challenging to sustain due to the limited food choices. It is important to consult with a healthcare provider before starting the keto diet to ensure it is done safely and under proper medical supervision.
