The main differences between standard and cyclical Keto diets
What is the standard ketogenic diet (SKD)
The standard ketogenic diet (SKD) is similar to a low-carb diet, but it allows some carbohydrate consumption. The SKD has less protein and more fat than the ketogenic diet, and because of this the body will burn the fat first before the carbohydrate is burned. There are no exceptions to the no carb restriction.
A ketogenic diet is really not a low-carb diet, because when the body is deprived of carbs (by the SKD or the standard ketogenic diet), the body simply runs out off fat, even though the body was eating fat and carbohydrates in the form of food. This is known as ketosis. In order to come back to a regular diet, the body will first need to be back into ketosis. So, this is why the results of the ketogenic diet are not guaranteed by many people who try it.
What is the cyclical ketogenic diet (CKD)
Another diet is the cyclical ketogenic diet (CKD)¹. This diet consists of alternating periods of very low-carbohydrate and very high-carbohydrate days. The basic premise of the CKD is that your brain is able to adapt to your diet.
The Cycles Ketogenic Diet (CKD) revolves around alternating between high-carbohydrate days and low-carbohydrate days. You will start out by eating a few bits of protein on the high-carbohydrate day and then you will eat very little carbs on the low-carbohydrate day. This alternate cycle is supposed to allow your brain to “adapt” to the low-carbohydrate diet, which can have side effects, including nausea, dizziness, headaches, and loss of appetite.
Are there any other similar types of diets?
The Control-High-carbohydrate Ketogenic Diet (CHDK) is similar to the CHDK, except that you are allowed to eat some carbs again after the initial no-carb diet. This diet may not be as effective as the CKD since it only alternates between high-carbohydrate and low-carbohydrate days. There are more problems with this diet – some people report nausea, acne, and headaches after switching to this diet.
The Cycled High-Carb, Low-Protein Low-Fat (CHLF) is a low-carbohydrate diet that puts a lot of weight on in one day by using very little fat in the diet. Some people think that the CHLF will cause you to gain weight because it is high in carbs, but this is not true because the low-fat diet will give you a feeling of fullness for your food. The reason that the CHLF diet will keep you from gaining weight is because the very low-fat diet gives you a constant feeling of hunger all the time.
The Cycled High-protein, Low-Carb (CHLF) is also similar to the CKD. Again, this diet does not allow any carb food because this will allow your body to adapt and will keep you from gaining weight. Always consult your doctor before making significant health-related lifestyle choices.
