Cyclic ketogenic dieting, also known as CKD, is a variation of the standard ketogenic diet (SKD). The ketogenic diet is a low-carbohydrate, high-fat diet that forces the body to enter a state of ketosis, where it primarily burns fat for fuel instead of carbohydrates.
In a cyclic ketogenic diet, the individual follows a pattern of alternating between periods of strict ketogenic eating and periods of higher carbohydrate consumption. Typically, the cycle consists of 5-6 days of strict ketogenic eating, followed by 1-2 days of higher carbohydrate intake.
During the strict ketogenic phase, carbohydrate intake is limited to very low levels (typically less than 50 grams per day), forcing the body to rely on fat for energy. This promotes fat loss and can lead to weight loss and improved body composition.
The higher carbohydrate phase, often referred to as the “carb-up” or “refeed” phase, allows the body to replenish glycogen stores and provides a temporary increase in insulin levels. This can help boost energy levels and support intense workouts. It may also prevent metabolic adaptation and hormone imbalances that can occur with long-term carbohydrate restriction.
Cyclic ketogenic dieting is popular among athletes and bodybuilders who desire the benefits of ketosis for fat loss and muscle preservation, while also periodically replenishing glycogen stores for optimal performance during intense training sessions.
