This article explains it better than I ever could
I have controversial views about dieting and controversial usually ends in heated arguments. But my theory is fasting is good, it is more beneficial than calorie counting and it’s easier.
However, as with everything, moderation is key and there are precautions to take before going on a long fast, the most obvious being potassium/magnesium deficit, which you will feel keenly if you don’t monitor it. Reddit has an active fasting community with a wealth of up-to-date information.

They even have a community for intermittent fasting, but I don’t know much about it.
