The key to anything like this is it has to be sustainable. Doing OMAD is great, but you might need to work up to it. 16/8 is often a good starting point, and then stretching it. But if you start it and can’t maintain it, it won’t work. But if you can do OMAD right off the bat, fantastic! Give it a go, but if you feel you can’t do it, don’t give up. Scale back a bit, and stretch out the fasting window until you get there.
Also, drink a lot of fluids. If you like herbal teas, make a big cup when you feel hungry and make a bit of a ritual out of it. I also drink a lot of flavored, unsweetened, sparkling water. Those things give some flavor and zero calories, don’t break your fast, and make me feel less hungry.
Good luck!
