Breaking a fast and fast period

Hello guys,i'm new to IF and started with the 16/8 method and have some questions about IF. What is the best way to break the fast? What should i eat first? Can i also make my fast period flexible? e.g. on working days 18/6 and on the weekend 16/8? via /r/intermittentfasting https://ift.tt/2KqNVAf https://ift.tt/eA8V8J
