> For eight hours from midday until evening (the exact times shift a little based on my waking and sleeping schedule; 2PM to 10PM is a pretty common schedule for me), I eat like a responsible adult. Minimal junk food, desserts in moderation, try to make my meals balanced, don't eat too much sugar or simple carbs. I don't deny myself anything I crave, generally speaking, but I try not to eat garbage.

So if you shift your example schedule two hours back to 12PM-8PM, isn't that just saying "I don't eat breakfast any more"? Lunch at noon, dinner at 6, a snack in between meals, and dessert at 7:30 would fit all the criteria you laid out, and indeed is something I end up doing pretty frequently, just without a faddish name like "intermittent fasting".
