Apparantly the guy that wrote Huckleberry fin was big into fasting.
It is good for you, theres no doubt about that.
I don't have a hard rule either. Usually after a vacations or a holiday weekend I feel like I need to "reset". After quitting drinking as heavily and trying to stick to keto/Paleo/carnivore I feel less of a need to "reset".
