I think most people would disagree with your definition of "quite simple".

Going from three meals a day to a 16:8 eating pattern (16 hrs fasting, 8 hrs eating window) isn't too bad. It's basically skipping breakfast. Shortening the eating window until you're eating one meal a day is tougher. Then extending the fasting period > 24 hrs is tougher still. You can't just jump into this stuff while you're carb-addicted and your body is screaming for glucose. Getting used to a keto-style diet, even if your carb intake is just low but not keto-low, helps a lot.

If you're a somewhat lazy young person like I was, falling into a one-meal daily routine could just happen due to a busy daily schedule. Unfortunately I also managed to put on weight during that time, so my meals of choice were probably non-optimal and probably too large.

I stand by that most people should be able to do it, as long as they can get over the hangry phase.
