A cyclic ketogenic diet or carb-cycling is a low-carbohydrate diet with intermittent periods of high or moderate carbohydrate consumption. This is a form of the general ketogenic diet that is used as a way to maximize fat loss while maintaining the ability to perform high-intensity exercise.
A ketogenic diet limits the number of grams of carbohydrate the dieter may eat, which may be anywhere between 0 and 50g per day. The remainder of the caloric intake must come primarily from fat sources and protein sources in order to maintain ketosis the condition in which the body burns fats and uses ketones instead of glucose for fuel.
When following a low carbohydrate diet , for the first few days, there is an adaptation period during which most people report feeling run-down or tired. Some people report feeling irritable, out of sorts, and unable to make decisions.
For most people, these feelings disappear after the adaptation period, however, and are replaced with feelings of calm and balance and more consistent energy. Although most people report a waning of cravings while in ketosis, some people may crave carbohydrates during ketosis for psychological reasons. During a hypocaloric ketogenic diet, the carb cravings may combine with hunger pangs , making matters worse. A CKD offers a way to combat this. It offers a cyclical "refeed" sometimes also called a carb-up.
During this phase, the diet consists mostly of complex carbohydrates , with limited fat, sucrose and fructose. Since the glycogen stores in the liver and muscles are depleted, these carbohydrates go straight to refilling them instead of being added to the body's fat stores.
For this reason, the amount of calories consumed during a refeed can be far above an individual's usual dietary intake. While a typical CKD consists of 50g or less of carbohydrate per day, the typical refeed consists of g of carbohydrate.
