Not eating for few days - is not (yet) starvation, its not 'body wasting away'.
Its a state where your body and mind need to be the sharpest in order to catch food. Or else due to lack of fuel you will enter actual starvation (no fat reserves).
When you have reduced calories intake ~~500kcal a day you are signaling to your body that you can find/catch food but there is not a lot of it. Your metabolism will slow down in order to adjust to reduce calories. You loose muscle mass much faster than when not eating at all.
I have done multiple >3 days fasts and I havent experienced this sharpness feeling though. It seems some people do and some don't.
Also worth mentioning keto is natural diet of Eskimo people, they survived generations eating seal's meat and fat. So keto is not some crazy nutjob diet invention of 21st cent.
