The ketogenic diet, or keto diet, is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. The diet involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts the body into a metabolic state called ketosis, where the body uses fat for fuel instead of carbohydrates. While there is no strict definition of a low-carb diet, anything under 100-150 grams of carbohydrates per day is generally considered low-carb. However, to reach ketosis, most people will need to consume fewer than 50 grams of carbohydrates per day. The standard ketogenic diet typically consists of 70% fat, 20% protein, and 10% carbohydrates.

What You'll Learn
The keto diet is a low-carb, high-fat diet
On the keto diet, high-carb foods are replaced with fatty foods such as eggs, dairy, meat, fish, and healthy oils like olive oil and coconut oil. Non-starchy vegetables are also recommended, as they are low in calories and carbs but high in nutrients like vitamin C and antioxidants. The keto diet also involves moderate protein intake, as excessive protein can prevent ketosis.
There are several variations of the keto diet, including the standard ketogenic diet (SKD), the cyclical ketogenic diet (CKD), the targeted ketogenic diet (TKD), and the high protein ketogenic diet. The SKD is the most studied and recommended version, with a ratio of 70% fat, 20% protein, and 10% carbs. The CKD involves cycles of 5 low-carb days followed by 2 high-carb days, while the TKD allows for more carbs around workouts. The high protein ketogenic diet is similar to the SKD but with a ratio of 60% fat, 35% protein, and 5% carbs.
It is important to note that drastically reducing carb intake can lead to symptoms like the "keto flu," and it may take several weeks for the body to fully adjust to this new way of eating. Additionally, while the keto diet can provide health benefits like weight loss and improved blood sugar control, it is always recommended to consult a healthcare professional before starting any new diet.

It causes the body to burn fat instead of carbs for energy
The keto diet is a low-carbohydrate method of eating that involves reducing net carbohydrate intake to around 50 grams a day. This is considered a low-carb diet, with anything under 100-150 grams per day generally falling under this category.
The keto diet causes the body to burn fat instead of carbohydrates for energy. This metabolic state is called ketosis. When carb intake is very low, the body's glucose stores deplete, and it is forced to burn fat for energy. This fat can come from dietary sources or the body's own fat stores. The body breaks down this fat into compounds called ketones, which become the body and brain's main source of energy.
Ketosis can be difficult to achieve and maintain, requiring careful tracking of food intake. It can also cause side effects such as "keto breath" and constipation due to the lack of fibre in the diet. It is also restrictive, limiting nutrient-rich foods like whole grains, fruits, and vegetables.
To compensate for the reduced carb intake, the keto diet recommends increasing fat intake to around 70-80% of total calories. This high-fat content is what makes the keto diet appealing to many, as it allows for the consumption of high-fat foods like red meats, fatty fish, nuts, cheese, and butter. However, it is important to prioritise healthy fats like monounsaturated and polyunsaturated fats to promote heart health.
The keto diet has been associated with potential weight loss, increased energy, and the treatment of chronic illnesses. It is also being studied for its potential benefits in reducing symptoms for patients with progressive neurological disorders. However, it is important to consult a dietitian or healthcare professional before starting any new diet.

This metabolic state is called ketosis
The ketogenic diet, or keto, is a low-carb, high-fat diet that offers numerous health benefits, including weight loss and a reduced risk of certain diseases. The diet involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts the body into a metabolic state called ketosis.
Ketosis is a metabolic state in which the body uses fat for fuel instead of carbohydrates. When the body is in ketosis, it starts breaking down stored fat into molecules called ketone bodies to use for energy when there is little to no blood sugar from food. This metabolic state can be reached by limiting carb intake to under 50 grams per day, though some sources suggest that 20 grams per day is the threshold for ketosis.
During ketosis, the body produces ketones, which are acids that appear in the blood and urine when the body burns fat. While ketosis is the goal of the keto diet, it is important to note that excessive protein consumption can prevent the body from reaching full ketosis. This is because when the body does not have sufficient carbs, amino acids from proteins will be turned into glucose via a process called gluconeogenesis. Therefore, a well-formulated keto diet should be high in fat and moderate in protein.
The standard ketogenic diet consists of 70% fat, 20% protein, and 10% carbs. However, there are several variations of the keto diet, including the cyclical ketogenic diet, which involves 5 low-carb days followed by 2 high-carb days, and the targeted ketogenic diet, which allows for more carbs around workouts. It is important to note that only the standard and high-protein ketogenic diets have been extensively studied.

The standard keto diet recommends 70% fat, 20% protein, and 10% carbs
The keto diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. The standard keto diet recommends 70% fat, 20% protein, and 10% carbohydrates. This means limiting carb consumption to around 20 to 50 grams per day and filling up on fats, such as meat, fish, eggs, nuts, and healthy oils like olive oil and coconut oil. Cheese is also allowed on the keto diet, as it is high in fat and protein.
It is important to note that the keto diet is not just about reducing carb intake but also about increasing fat intake. This is because when the body doesn't have enough carbs, it will start burning fat for energy, which is called ketosis. Ketosis is a metabolic state where the body breaks down stored fat into molecules called ketone bodies to use for energy instead of carbohydrates. To get enough fat in your diet, you should choose fatty cuts of meat and add healthy fats to your meals, such as olive oil and coconut oil.
It is also important to moderate your protein consumption on the keto diet. This is because if you eat too much protein, it can be converted into glucose, which may slow down your transition into ketosis. The average recommended daily protein intake for a person assigned female at birth following a keto dietary plan is 46 grams, and for a person assigned male at birth, it is 56 grams.
There are a few different variations of the keto diet, including the cyclical ketogenic diet (CKD) and the targeted ketogenic diet (TKD). The CKD involves 5 ketogenic days followed by 2 high-carb days, while the TKD allows you to add carbs around workouts. The standard keto diet has been the subject of most research and is the most recommended.

There are other keto diets, such as the cyclical ketogenic diet
The keto diet is a low-carb, high-fat diet that offers many health benefits, including weight loss and lowering the risk for certain diseases. The standard ketogenic diet (SKD) is the most researched and recommended version, with 70% of a person's intake coming from fat, 20% from protein, and 10% from carbohydrates. This typically amounts to 20 to 50 grams of carbohydrates per day.
The high-protein ketogenic diet is also an option, with 60% of a person's intake coming from fat, 35% from protein, and 5% from carbohydrates. Additionally, the MCT ketogenic diet has been used to treat epilepsy, as it allows for more carbohydrate and protein consumption while maintaining ketosis. This diet includes MCTs (medium-chain triglycerides), which are found in coconut oil and can also be consumed as MCT oil or emulsion liquids. However, MCTs can cause stomach upset and diarrhoea if consumed in large quantities.
It is important to note that the keto diet may have side effects, and it is recommended to consult a doctor or dietitian before making any significant dietary changes. Additionally, the keto diet may not be suitable for everyone, including pregnant women, people with diabetes, or those with a history of kidney stones.

Frequently asked questions
The keto diet is a low-carb, high-fat diet. The standard ketogenic diet recommends that 70% of a person's intake is fat, 20% is protein, and 10% is carbs. This equates to under 50 grams of carbohydrates per day, though the exact amount varies depending on the individual.
Ketosis is a metabolic state in which the body uses fat for fuel instead of carbohydrates. When the body uses fat as energy and releases ketones, this is called ketosis.
Net carbs are the number of digestible carbs in a serving of food. To calculate the number of net carbs, subtract the fibre content from the total number of carbs. If the food is processed, also subtract half of the sugar alcohol content.
