I think this is an entirely relative situation, I've only eaten once a day for nearly 10 years now and to be honest its pretty close to when I fall asleep, often after having worked 8-12 hours in physical job and 2-3 hours at the gym. I can eat between 2-5000 calories in one sitting depending on how stressed/tired or ultimately hungry I felt. I went several years sleeping only 3-4 hours a day in my 20s. I'm more reluctant to do that now in my 30s and it was almost never by choice, but what was always a constant is that I normally only ate until moments I was about to fall asleep. And I'm entirely healthy and have way more energy than people in my age group and as much as 7-8 years younger than myself. It does take me longer to fully recover from an injury or cold these days than when I was in my teens or even 20s, and while I really enjoy sleep (I spent significantly more on a bed when I was 21 than what I spent going to the bar in the following 4 years) and food I don't think its an absolute that its an absolute to keep the 2 so separate to achieve those goals. I have an incredibly fast metabolism, too. I still have to workout on a regular basis and eat 3k+ calories to just keep my weight constant. I think I'm one of the few in my group of friends whose actually lost weight during this lockdown. Now that gyms are starting to open up I need to get a few session in to see just how much of that was muscle loss as I barely kept up with any routine due to having bad joints in my upper body.
