In the event that blood sugar cannot be made from food, the body will begin to use stored fat for energy and build molecules called ketone bodies (this process is called ketosis). When the body reaches a state of ketosis, most cells will begin to use ketone bodies to generate energy for the body. Your body will switch from using blood sugar to using stored fat as an energy source. Usually, this process happens in two to four days, after you eat less than 20 to 50 grams of carbohydrates per day. You should remember that this is individual and that some people need more limited amounts of sugar to start producing enough ketones.
