On a CKD, you eat carbs strategically by alternating days of ketogenic dieting with days of “carb-loading” during which you eat around 450-600 grams of carbohydrates to refill muscle glycogen.
The “carb-loading” phase, typically lasts for 24-48 hours. This diet is used to maintain exercise performance and build lean body mass. For it to work, you must do very intensive workouts that will completely deplete muscle glycogen within set time frames. For this reason it is not recommended for nor the majority of people. During the carb-loading phase of the CKD, the body’s metabolism is temporarily switched out of ketosis, with the goal of refilling muscle glycogen levels to sustain exercise performance in the next cycle.
