As we have seen in other articles, when carbohydrate intake is drastically reduced (not to zero because carbohydrates, even in small proportions, are present in many foods), the liver uses the fatty acids in adipose tissue to generate ketone bodies.
So, the energy your body uses on the keto diet is ketone bodies, which are fat waste.
It's a slow and costly metabolic pathway. But the important thing is that it requires large amounts of fat to obtain the same energy it would from carbohydrates. That's why it helps with weight loss.
