This. From my experience doing Keto and based on what I’ve read, your body enters ketosis after blood glucose drops very low. When that happens, it switches to ketones for fuel. It doesn’t need glucose anymore (although glycogen plays a role).

The assumption here is that this is a temporary/reversible condition. At least it was in my case.

For the record, I did a low carb diet for 6 months. I was in ketosis for much of it, with temporary periods of break when it was unavoidable (during travel, lack of food options, social setting). I feel exogenous ketones helped me with the process of getting back in ketosis.
