The Johns Hopkins Hospital protocol for initiating the ketogenic diet has been widely adopted. It involves a consultation with the patient and their caregivers and, later, a short hospital admission. Because of the risk of complications during ketogenic diet initiation, most centres begin the diet under close medical supervision in the hospital.
