It’s less about eating windows and more about making sure you hit your minimum fasting goal during your fasting window. It really doesn’t matter when you eat as long as you fast for long enough. You can coordinate your day however you want! It’s most common to have lunch/dinner though.
I find that it’s easier to begin my day not eating and end it eating. If I get up and eat I am going to want to eat for the rest of the day. I’ve had very little success keeping a fast going with a morning eating window. But I also have a crap relationship with food, everyone is different.
