I've heard there's a new diet craze called the ketogenic diet. What is it?

The ketogenic diet is a high-fat, low-carbohydrate diet that has been popularized by the book "The Keto Diet" by Dr. Dominic D'Agostino. It involves drastically reducing your carbohydrate intake and replacing them with fat. This helps to kickstart a metabolic state known as ketosis, which causes the body to burn fat for energy instead of carbohydrates.
