Yes, however it's not that simple. Your body has a process by which it turns pure fats into glycogen and regulates your blood sugar to normal levels during periods of low carb availability, but if you aren't used to it and have never done keto you will feel like absolute shit for the first week.
And if you care about athletic performance it will take your body anywhere from 1-3 months to fully adapt to low carb and have equal performance to when you were eating carbs. There's also other changes to your body because of how fat oxidation works, personally I enjoy low carb because I don't feel like bloated shit after every meal (you have to experience this to understand it) and it makes cooking easier.
