The ketogenic diet is a high-fat, low-carbohydrate diet that has been used since the 1920s to reduce seizures in children with epilepsy. More recently, it has become a popular weight-loss tool. While the standard keto diet is the most popular form, there are several other ways to follow this regime, including keto cycling or the cyclical ketogenic diet. Keto cycling involves following the keto diet for a certain amount of time and then taking a day or more off. The idea is to make the keto diet easier to follow, as knowing there is a day in the near future when you can eat carbs again might help you stick to the diet for longer. However, some experts warn that keto cycling might lead to disordered eating and cause people's weight to fluctuate.

The cyclical ketogenic diet is a less restrictive, more sustainable way to get the benefits of a ketogenic lifestyle
The ketogenic diet is a high-fat, very low-carb diet. Typically, those following the keto diet restrict their carb intake to under 50 grams per day. This causes the body to burn fat for energy instead of glucose, in a process known as ketosis. While in ketosis, the body uses ketones, which are byproducts of fat breakdown produced by the liver, as an alternative energy source.
The cyclical ketogenic diet (CKD) is a variation of the standard keto diet. It involves adhering to a standard ketogenic diet protocol 5–6 days per week, followed by 1–2 days of higher carb consumption. These higher-carb days are often referred to as "refeeding days" as they replenish the body's depleted glucose reserves. During the refeeding phase, carbs should comprise 60–70% of total calories, protein should account for 15–20%, and fats should deliver just 5–10%.
The cyclical keto diet is often compared to carb cycling, but they are not the same. Carb cycling involves cutting carbs on certain days of the week while increasing intake on others. However, carb cycling does not reduce overall carb intake drastically enough to reach ketosis. On the other hand, the cyclical keto diet brings the body in and out of ketosis.
Keto cycling is a form of the cyclical ketogenic diet. It involves following a ketogenic diet for a few days in a row and then taking a break to eat high or average levels of carbohydrates for a day. This approach is touted as a less restrictive and more sustainable way to get the benefits of a ketogenic lifestyle. Some proponents of keto cycling say that it can help prevent some of the common side effects of a full-on keto diet, such as fatigue, nausea, diarrhea, and other "keto flu" symptoms. It is also mentally easier to stick to in the long run and allows for more variety in the diet.
However, not everyone agrees that keto cycling is healthy. Some health experts say that the keto diet is not usually sustainable or healthy to follow for long periods. There are concerns that the keto diet can promote disordered eating and that keto cycling, in particular, can lead to binge behaviors. There are also concerns about the health effects of cycling in and out of ketosis, as it may be dangerous for a person's body to store too much consumed fat, which can result in high triglycerides and cholesterol.

Cyclical keto involves a mostly ketogenic diet mixed in with limited carb days
The cyclical ketogenic diet is a variation of the standard ketogenic diet. It involves adhering to a standard ketogenic diet protocol for 5–6 days per week, followed by 1–2 days of higher carb consumption. These higher-carb days are often referred to as "refeeding days" or "cheat days", as they replenish your body's depleted glucose reserves and glycogen stores. During the standard ketogenic days, it is recommended to consume 20-50 grams of carbohydrates per day.
The cyclical keto diet is often compared to carb cycling, but it is not the same thing. Carb cycling involves cutting carbs on certain days of the week while increasing intake on others, without drastically reducing overall carb intake enough to reach ketosis. On the other hand, the cyclical keto diet involves modifying the standard keto diet with days of higher carb intake to bring your body in and out of ketosis.
Keto cycling is considered a less restrictive and more sustainable way to get the benefits of a ketogenic lifestyle. It is touted as a way to continue the ketogenic diet after an initial 30- to 90-day period of everyday carb restriction. Some proponents of keto cycling say that it can help prevent some of the common side effects of a full-on keto diet, such as fatigue, nausea, diarrhea, and "keto flu" symptoms. However, it is important to note that there are no published studies on keto cycling versus a regular ketogenic diet, and there are concerns about potential negative health impacts.
Cyclical keto is primarily used by bodybuilders or athletes who need to restore glycogen stores. Carb cycling is usually based around variable carbohydrate intake throughout the week, with high, moderate, or low carb days. High carb days are reserved for intense workouts, while low carb days are for rest days.

Carb cycling involves cutting carbs on certain days of the week while increasing intake on others
Carb cycling is a popular alternative to the traditional keto diet, which is often considered inflexible. Carb cycling involves cutting carbs on certain days of the week while increasing intake on others. This method allows for more flexibility with carb consumption and can make the keto diet easier to follow.
Typically, each week is divided between 4–6 days of lower carb intake and 1–3 days of higher intake. During the low-carb days, individuals adhere to a standard ketogenic diet protocol, restricting carb intake to under 50 grams per day. On the higher-carb days, individuals consume a larger number of carbs, typically in the range of 300-400 grams, depending on their activity level.
The higher-carb days are often referred to as "refeeding days" or "cheat days," as they replenish the body's depleted glucose reserves. During these days, the body temporarily exits ketosis, a state where the body burns fat for energy instead of glucose. While in ketosis, the body uses ketones, byproducts of fat breakdown, as an alternative energy source.
Carb cycling is often used to promote weight loss, boost athletic performance, and encourage muscle growth. It can also help alleviate some of the common side effects of a full-on keto diet, such as fatigue, nausea, and diarrhea. However, it's important to note that not all health experts recommend the keto diet, as it can lead to kidney trouble, increased intake of unhealthy fats, and nutrient deficiencies.
Before starting any new diet, it's always recommended to consult with a healthcare provider to determine if it's right for your individual needs and health status.

Keto cycling can be much easier to stick to in the long run, and it allows for more variety in the diet
Keto cycling is a variation of the standard ketogenic diet. It involves adhering to a standard ketogenic diet protocol for 5–6 days per week, followed by 1–2 days of higher carb consumption. The high-carb days are referred to as "refeeding days", as they replenish the body's depleted glucose reserves. During the refeeding phase, carb quality matters, and it is recommended to opt for complex carbs like fruits, sweet potatoes, and whole grains.
Keto cycling is touted as a less restrictive and more sustainable way to experience the benefits of a ketogenic lifestyle. The standard ketogenic diet is often considered inflexible, and keto cycling provides more variety in the diet, making it easier to stick to in the long run. Knowing that there is a day in the near future when carbs can be consumed again may help dieters stick to the diet for longer. Additionally, alternating between ketogenic and higher-carbohydrate days can help prevent common side effects of a full-on keto diet, such as fatigue, nausea, diarrhea, and "keto flu" symptoms.
However, it is important to note that keto cycling may not be suitable for everyone. Some experts warn that cycling in and out of ketosis may be dangerous, potentially leading to high triglycerides and cholesterol. Additionally, there is a concern that restrictive diets like keto and keto cycling may promote disordered eating and nutritional deficits. Before starting keto cycling, it is recommended to consult a healthcare provider to ensure it aligns with your health needs and goals.
While keto cycling can provide flexibility and make the keto diet easier to follow, it is important to remember that there is no one-size-fits-all approach to dieting. Tracking your body's response to keto cycling and adjusting as needed is essential. Additionally, it is recommended to wait until your body is adapted to ketosis before incorporating keto cycling, as this will make it easier for your body to re-adapt to ketosis after consuming carbs.

Cyclical keto may be easier to follow than conventional keto. Knowing that there will be days in the near future when carbs can be eaten again may help people stick to the diet for longer. It may also reduce keto flu symptoms, which include nausea, fatigue, headaches, constipation, weakness, difficulty sleeping, and irritability.
However, there are some unpleasant side effects associated with cyclical keto. It may be easy to consume too many calories on refeeding days, counteracting the weight loss benefits of the standard keto diet. Transitioning from standard to cyclical keto may also result in temporary weight gain due to excess water retention. In addition, the high-fat nature of the keto diet could negatively impact heart health and lead to increased cholesterol levels.
Furthermore, the keto diet can be difficult to maintain due to its restrictiveness, and it may promote disordered eating and binge behaviours. There is also a concern that cycling in and out of ketosis may be dangerous, potentially leading to high triglyceride levels and cholesterol.

Frequently asked questions
Keto cycling involves following a ketogenic diet for a few days and then taking a break by eating high or average levels of carbohydrates for a day. This is also known as carb cycling, as there are lower-carb and higher-carb days.
Keto cycling is a less restrictive and more sustainable way to get the benefits of a ketogenic lifestyle. It can also help prevent some of the common side effects of a full-on keto diet, such as fatigue, nausea, and diarrhea. Keto cycling also allows for more variety in the diet, which is good for physical health.
Keto cycling may not be as effective as a traditional keto diet for weight loss, as taking days off the diet can halt weight loss and may even lead to weight gain. It can also be challenging not to overindulge on the days off the diet, and some people experience a "'carb hangover' when reintroducing carbohydrates.
There are no strict rules for keto cycling, but it is recommended to wait until you are about two to three months into your keto diet before trying it. On the higher-carb days, it is best to stick to whole foods with low amounts of sugar, such as fruit, sweet potatoes, and whole grains.
