An analogy for ketogenic diet. If you have a car that runs on gasoline (Keytones) and you add diesel fuel (glucose) on a regular basis with your gasoline your car will run but your performance will be diminished eventually clogging up your engine to the point it will not be able to perform enough to move the vehicle but will run at an idle with a great deal of smoke. Flush the gas tank, put in the proper fuel and after awhile the engine will clean up and run fine again.
