When a fasting person has burned up all his glucose stores, he then begins to burn stored body fat for energy. After the initial fasting period, a person on the ketogenic diet derives his energy principally by burning the exogenous dietary fat rather than from the more common energy source, carbohydrate (glucose), or from their own body fat. But unlike fasting, by providing exogenous fat the keto- genic diet allows a person to maintain this fat-burning metabolism as its primary source of energy (instead of glucose) over an extended period of time.
In the absence of glucose, the fat is not burned completely but leaves a residue of soot or ash in the form of ketone bodies, and these …show more content…
In the presence of large levels of ketone bodies, seizures are frequently controlled. THE BASICS REMINDER: The traditional ketogenic diet is a rigid, mathematically calcu- lated, doctor-supervised therapy. This diet should only be attempted under close medical and dietary supervision. The ketogenic diet simulates the metabolism of a fasting individual. A fasting per- son burns stored body fat for energy; a person on the ketogenic diet derives energy principally from the fat in the diet rather than from the more common energy source, carbohydrate. But unlike fasting, the ketogenic diet allows a person to maintain this fat-burning over an extended period of time. Traditionally, the diet has been initiated over 3 days after a 48-hour period of fasting (a limited amount of carbohydrate-free fluids are allowed during this period). More recent studies (dis- cussed in Chapter 7) have questioned whether fasting, slow initiation, or even the traditional ketogenic diet itself is necessary for seizure control.
