There are papers reporting that very low calorie diet (VLCD) has similar effects. Not sure whether IF is any special when compared to VLCD rather than the baseline (no intervention).
There's only so much food you can stuff in your face during the eating window - and if you time it right, you'll be asleep for pretty much half the fast time anyway.
Last meal around 20:00 in the evening, skip breakfast, lunch at noon. That's a 16 hour fast easily.
After you fast for a while (a week or two) your body gets used to it and it gets easier, any feelings of hunger go away pretty fast.
IF on the other hand doesn't require you to eat less calories than your body requires. Skipping breakfast works pretty effortless on the long term.
