You wrote "...my body otherwise cannot function for the day"? What have you tried? How certain are you that you body cannot break the morning fast? Many people who do intermittent fasting go without eating from, say, 8 pm to noon the next day (16 hours). If you sleep between ~10 pm and ~6 am, in my experience, you might have a little bit of hunger at some points in the morning, but you can get used to it. I typically felt great on days I did it.
