The problem is that once the glycogen is gone, your body has to turn to protein for the glucose it does need and if you are fasting, that means muscle eventually (once autophagy cleans up the extra).
I did very low carb (basically zero carb) for more than a year and never really got over the keto flu completely. Some people adapt well and some don't and I'm apparently of the latter. I did lose a fair amount of weight doing that but nuked my thyroid in the process so avoid VLC now, short of a one day fast.
