How Does Ketosis Work?

However, things are different on keto. On the ketogenic diet, your carbohydrate intake is kept very low—so when those carbs aren’t present, your body must utilise another form of energy to keep things moving forward.

That’s where fats come in. In the absence of carbs, the liver takes fatty acids in the body and converts them to ketone bodies, also known as ketones, as an energy source. This process is known as ketosis, and the goal for those on the ketogenic diet is to enter ketosis.

Ketones supply superior energy for the body, brain and the heart, in fact, the brain will utilse ketone bodies at a much higher rate than glucose and will provide over 70% of it's energetic requirements. 

Being in a ketogenic state allows us to burn fat for fuel, this could be dietary fat, body fat, or both. Even the leanest person you know carries around 150,000 calories of energy as stored fat, so we have a constant supply of fuel.

We can manipulate whether we're burning predominantly dietary fat or body fat by increasing or decreasing the volume of fat we consume. 

As we lower the dietary fat slightly, our body's will use more stored fat for fuel.
