As a health approach, it is way to go into keto. The liver produces ketones from fat. These ketones then serve as a fuel source throughout the body, especially for the brain. On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off.
There are various ways to fast, and it is best to find the way that is easiest for you.
