Hiw long have you been doing IF? It takes some time for your brain to adjust and stop sending hunger signals at the usual times. You will also learn that it does not last, and that you don’t have to eat just because you’re hungry for a while - that’s something that’s been ingrained in our first world brains. Food is so abundant that we’re never hungry anymore and we think it shouldn’t happen or that we should act in it immediately. Well, we really don’t have to, and it goes away after a while.
Around 9am is the only time I ever get hungry anymore, for some reason, but it’s a lot more manageable than it was during my first couple of weeks. At first I had to do something, like drink a couple glasses or water, or a coffee, to help. Now I just plain ignore it. Never lasts more than half an hour.
So as long as you’re not feeling faint or dizzy, have a glass of water, tell your brain that’s all it’s gonna get until noon, and move on.
If it’s truly unbearable, eat more during your eating window.
Are you drinking or eating ANYTHING when you wake up or before that first break? I have found that even Powerade zeros artificial sweeteners causes a reaction(assuming insulin) and I get extremely hungry early. Black coffee and water only during my fasts otherwise I suffer
