You can adjust if you want to.
It will be difficult at first but does get easier. So the first day you cave and eat lunch. You’ll make it longer the next day and after a couple of weeks you will have adjusted 100%.
And chances are you’ll be going to bed earlier and can even move your eating window up a bit to compensate?
AND IMO there is no single better feeling in the world than going to work in the morning with your workout DONE.
That is worth a lot to me, so much so that I can handle a bit of hunger.
You could try OMAD+ on workout days - I’m insinuating from your post that you do OMAD. Which is just fasting for at least 16 hours and then breaking fast with a small meal or snack until later eating an OMAD meal. I do this with a protein shake, more for the nutrients on days I work out than the calories, but this at least gets something in my stomach a few hours after a workout rather than waiting all day.
