As we all know that carbohydrate is the main source of fuel our body uses to get energy and if there is a lack of carbs the body automatically turns to protein to gain energy. When the amount of both carbs and proteins are restricted it turns to burn fat reserves to provide energy. So keto diet is mainly based on fats.

So keto dieters are instructed to consume a minimal amount of carbs (around 5%), a low amount of proteins, and a high amount of healthy fats (around 80%).
