The point still stands though.
I ate 5 or 6 times a day for 15-20 years. I would eat 3 meals, a snack in the afternoon, and then something before bed. And probably more than that to be honest. I was as much of a snacker as anybody.
In April I switched to eating 2 meals a day. I was very hungry for literally 1 or 2 days, and then I just got used to it, and started to like it!
Before that I was on a pretty strict diet for ~4 years. But I relaxed the diet after changing the schedule, and lost about 5 lbs. So the heuristic of just eating twice a day turns out to be easier to maintain than a diet.
Go figure! It was kinda shocking. I do think "3 meals a day" is a relatively recent thing. Millions of people lived for thousands of years without eating 3 meals a day.
Some downsides: I eat bigger meals, and I notice a bigger "tired" crash after dinner. But I think that's better than feely slightly groggy multiple times a day. I definitely am more aware of the fact that eating "slows you down". I do think there is something to the "alert, fasted" state, and I would call that pleasant.
Also I might have slowly gained back the 5 pounds but I'm still under my target weight ("normal" BMI which is like 20th percentile). I think after 6 months your body probably gets used to it, and maybe I relaxed the diet a bit too much. I'll continue to tweak it in the future.
An upside not to be discounted is that I spend less time and money on food, and traveling is a lot easier as a result!
