Keto Diet: Counting Carbs For Weight Loss

The ketogenic (keto) diet is a low-carb, high-fat eating plan that has been used to treat various medical conditions. While on the keto diet, the body enters a state of ketosis, where it burns fat for energy instead of carbohydrates. To stay in ketosis, a person can consume up to 50 grams of carbs per day, with the specific number varying from person to person. The keto diet involves calculating net carbs, which are calculated by subtracting fibre and sugar alcohols from the total carb content. This diet has gained attention as a potential weight-loss strategy, and it has been clinically proven to improve conditions like obesity and high blood pressure.

The keto diet recommends a daily intake of 20-50 grams of net carbs

The keto diet is a low-carb, high-fat eating plan that has been used for centuries to treat specific medical conditions. The diet restricts carbohydrates and replaces them with fats, putting the body into a state of ketosis. The number of carbs one can consume and stay in ketosis varies between individuals, but generally, a person should consume up to 50 grams of net carbs per day to stay in ketosis.

Net carbs are the amount of carbohydrates that are absorbed into the body. Some sources of carbohydrates, like fiber and sugar alcohols, are not absorbed into the bloodstream and, therefore, are not part of the daily allowance of net carbs. On the keto diet, it is recommended to consume no more than 50 grams of net carbs per day, and the fewer, the better.

To calculate net carbs, one must subtract the amount of dietary fiber and half of the amount of sugar alcohols from the total carbohydrate amount. This will give the amount of net carbs in the food. For example, if a food has 20 grams of total carbohydrates, 8 grams of fiber, and 5 grams of sugar alcohols, the net carbs would be 7 grams (20 - 8 - 5 = 7).

It is important to note that net carbs are different from total carbs, and by focusing on net carbs, one can still ensure their body gets the essential fiber it needs for proper function.

While the keto diet recommends a daily intake of 20-50 grams of net carbs, it is not suitable for everyone. It can be potentially harmful to people with type 2 diabetes who are on insulin and those with type 1 diabetes who must take insulin. Additionally, it is important to consult with a doctor or registered dietitian before starting the keto diet, as it can be very restrictive and challenging to maintain.

To calculate net carbs, subtract fibre and sugar alcohols from the total carb amount

To calculate net carbs, you must subtract the amount of fibre and sugar alcohols from the total number of carbohydrates. This is because fibre and sugar alcohols are not absorbed into the bloodstream and, therefore, are not part of your daily allowance of net carbs.

Net carbs refer to the total amount of digestible carbohydrates in a food product or meal. Net carbs are absorbed by your body and can be calculated by looking at the label and following these two steps:

• Determine the total carb content by looking at the number of total carbohydrates, then the amount of fibre and any sugar alcohols.
• Subtract the amount of dietary fibre and half the amount of sugar alcohols from the total carbohydrate amount. The result is the amount of net carbs in the food.

For example, if a food contains 20 grams of total carbs, 10 grams of dietary fibre, and 10 grams of sugar alcohols, subtract all 10 grams of the fibre and 5 grams of the sugar alcohols from the total carbs. This leaves 5 grams of net carbs.

It is important to note that the Food and Drug Administration (FDA) does not recognise the term "net carbs" and instead recommends using the total carbohydrates listed on nutrition labels. Additionally, not all sugar alcohols are treated equally when calculating net carbs. Erythritol, for instance, can be completely subtracted from the total carbs, whereas other sugar alcohols can only be partially subtracted.

Calculating net carbs can be beneficial for people with diabetes as it helps them track their intake of dietary fibre and balance their medications with their carb intake. However, it is always recommended that people with diabetes consult their doctor, dietitian, or diabetes educator before starting a low-carb diet to ensure they are getting the right amount of carbs for their individual needs.

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

The keto diet is distinctive for its exceptionally high-fat content, typically 70% to 80%, though with only a moderate intake of protein. The premise of the keto diet for weight loss is that if you deprive the body of glucose, its main source of energy, an alternative fuel called ketones is produced from stored fat. The brain demands the most glucose, about 120 grams daily, and cannot store glucose. During fasting or when very little carbohydrate is eaten, the body first pulls stored glucose from the liver and temporarily breaks down muscle to release glucose. If this continues for 3-4 days and stored glucose is fully depleted, blood levels of insulin decrease, and the body begins to use fat as its primary fuel.

The keto diet typically reduces total carbohydrate intake to less than 50 grams a day, with some sources suggesting less than 20 grams a day. Generally, keto diets suggest an average of 70-80% fat from total daily calories, 5-10% carbohydrate, and 10-20% protein. For a 2000-calorie diet, this translates to about 165 grams of fat, 40 grams of carbohydrates, and 75 grams of protein.

The keto diet is considered a low-carb diet when carbohydrate intake is less than 150 grams per day. The standard ketogenic diet (SKD) is the most common form, with a very low-carb, moderate-protein, and high-fat composition. The cyclical ketogenic diet (CKD) and targeted ketogenic diet (TKD) are variations that allow for non-consecutive days or pre-workout periods of higher-carb intake, respectively. The high-protein ketogenic diet (HPKD) is another variation that includes more protein and less fat.

To achieve ketosis, a state where the body burns fat for fuel instead of carbohydrates, most people will need to consume fewer than 50 grams of net carbs per day. Net carbs are calculated by subtracting fibre and sugar alcohols from the total carbohydrate amount. Net carbs are absorbed into the body, while sources of carbohydrates like fibre and sugar alcohols are not.

While on the keto diet, it is important to consume a variety of the allowed meats, fish, vegetables, fruits, nuts, and seeds to ensure adequate intakes of fibre, B vitamins, and minerals. It is also crucial to consult with a physician and dietitian before starting the keto diet to ensure it is safe and to monitor any biochemical changes.

Ketosis is a metabolic state where the body uses ketone bodies as its primary fuel source

The keto diet is a low-carb, high-fat diet that puts the body into a state of ketosis. Ketosis is a metabolic state in which the body uses ketone bodies as its primary fuel source. Ketone bodies are water-soluble molecules or compounds that contain ketone groups and are produced from fatty acids by the liver. The liver produces ketone bodies during periods of caloric restriction, such as low food intake, fasting, carbohydrate restriction, starvation, and prolonged intense exercise.

During ketosis, the body burns fat instead of carbohydrates for energy, causing glucose levels to drop. This shift in fuel source forces the body to produce ketones, which are acids that appear in the blood and urine when the body burns fat. The three main ketone bodies are acetoacetate, beta-hydroxybutyrate, and acetone. These ketone bodies are released into the blood and can be used by other tissues in the body, including the brain and heart, as an alternative energy source.

To stay in ketosis, a person on the keto diet should consume no more than 50 grams of carbohydrates per day. This typically involves eating high-fat foods and very low levels of carbohydrates, excluding some fruits and vegetables, bread, beans, and legumes. The keto diet has been associated with weight loss and improved management of type 2 diabetes.

In addition to the standard keto diet, there are a few variations, such as the cyclical ketogenic diet, which involves five low-carb days followed by two high-carb days, and the targeted ketogenic diet, which allows for more carbs around high-intensity workouts. It is important to note that the keto diet can be restrictive and may cause side effects, so it is recommended to consult a doctor or dietitian before starting this or any other diet.

Ketogenic diets have been used to treat specific medical conditions

To stay in ketosis, a person should consume no more than 50 grams of carbohydrates per day. The ketogenic diet is a high-fat, low-carbohydrate diet that replaces carbohydrates with fats, putting the body into a state of ketosis. Ketogenic diets have been used to treat specific medical conditions, such as epilepsy and mental illness.

Ketogenic Diets and Epilepsy

The ketogenic diet has been shown to be effective in treating seizures in people with epilepsy, particularly in children whose seizures have not responded to medication. The diet is usually started in the hospital under close medical supervision and involves carefully measuring calories, fluids, and proteins. The diet is very low in carbohydrates, which means that fats become the primary fuel source for the body. Ketones, which are formed when the body uses fat for energy, are one of the likely mechanisms of action for the diet's effectiveness in controlling seizures. Over half of the children who go on the ketogenic diet experience at least a 50% reduction in the number of seizures, and some, around 10-15%, become seizure-free.

Ketogenic Diets and Mental Illness

A pilot study conducted by researchers at Stanford Medicine found that the metabolic effects of a ketogenic diet may help stabilize the brain in people with serious mental illnesses such as schizophrenia or bipolar disorder. The study showed that the diet not only restored metabolic health in these patients but also improved their psychiatric conditions. The participants reported improvements in energy, sleep, mood, and quality of life. The researchers hypothesized that just as a ketogenic diet improves the body's metabolism, it may also improve the brain's metabolism, providing ketones as an alternative fuel source for the brain.

Other Potential Benefits

The ketogenic diet may also offer potential solutions for health conditions like obesity and type 2 diabetes. Additionally, the diet may help lower cholesterol levels, especially in people with type 2 diabetes.
