The Ketogenic diet defines the diet which is mainly followed to overcome the epilepsy in children. Epilepsy is a class of neurological disorders which is a long term disease. This diet contains fats in high quantity, sufficient proteins and less amount of carbohydrates. It allows burning of only fats in our body rather than carbohydrates. The main function of carbohydrates is to transform food into glucose which circulates in our whole body. This glucose provides energy to the brain which helps in proper functioning of our brain. But if we take less amount of carbohydrates, the liver transforms fats into ketone bodies. The ketone bodies make a path to our brain and take over the form of glucose which acts as an energy source for our brain.
