As a quick summary, if you need it, the keto (also known as the ketogenic diet) is a low-carb, high-fat diet (LCHF).

The whole concept of the keto diet is that your body transitions from burning glucose, in simple terms, sugars or carbohydrates, to burning fat as its primary fuel source.

For a keto diet, people will restrict their macros to eating;

  • 70% of their calories are from fat
  • 25% from protein
  • 5% from carbohydrates

Sticking to these macros for a period of time will put your body into a state of ketosis.

Ketosis is when your body has transitioned from burning carbohydrates as its primary fuel source to burning fat for fuel. It is at this point that you will start to see and feel the benefits of the keto diet.

It is the role of the liver to convert amino acids into small amounts of glucose. This process is called glucogenesis. This is when ketone bodies (ketones) are created.
