Natural, no. Again, optimal? We have sleep for fasting, to me it would seem optimal to be fed while awake. A few hours in the morning and night to prolong the fasted sleep state might be ok to help with digestion but i dont see how fasting until afternoon is in any way optimal, even if it was a common event in our past (which is just speculating).
I like to wake up and eat to remind me of my white privilege.
The problem arises when one has substantial fat to lose. I find IF to be helpful for that and for my digestion. PUFA liberation is inevitable in a deficit, so I can only mitigate the damage by supplementing vitamin e, niacinamide, and aspirin but I'm not taking aspirin at this time. I eat nutritional yeast for the b vitamins. Peat recommends slow weight loss, which I agree with. IF might not be optimal, but it can be useful to some people.
Sitting around molly codling our metabolisms when we are healthy might seem optimal but it isn't. J3nn's IFing while mildly stressful is giving her metabolism something to adapt to. If it is an every day occurance (now a chronic stressor) I'll probably lean your way and say it is less than optimal.
Refrigerators and supermarkets have made our metabolisms soft.

Definitely not every day. I am not that dedicated to anything. Some days it just happens naturally. I often wake up not hungry and get preoccupied with life. It varies from day to day, week to week. I am trying to minimize stressors but realistically, there will be some, so I choose my battles.
Health-related update: For the first time in a long, long time, I'm showing signs of progress on the hormone front. This is the first time in over a year that I had a month without a debilitating AF visit. And YB, I'm on a 4-day progest-e streak, go me! ha

Re. IF: I used to do that pre - Peat, when for a long while I ate all my meals within a 4 hr. window, in the afternoons.
Now I consider coffee with milk and sugar first thing in the morning to be a break-fast. I tend to drink small meals during the first half of the day.
I'm having easier time losing weight now, but that's more likely to the different macro ratio and the type of foods rather than my meal frequency. My calories overall are about the same as before, if not even slightly more, but very consistent.
