That’s quite fine as it’s individual. My SO can’t eat right after waking up but he really needs his food when hours pass and it’s already 6am…
I am in my middle of sleep at that time but even when I wake up, wonderfully satiated, even feeling full, with a negative appetite (so eating is borderline impossible anyway), I refuse to force-feed myself, probably ensuring obesity in the far future and lots of hunger during the day.
I overeat just fine, even massively sometimes if I start my day at 3pm, thank you very much. Eating even earlier (actually, 3pm is a bit too early…) wouldn’t do me any good, to put it lightly.
So both is right. Some people need breakfasts and some people badly need skipping it.
I am no farmer and no hunter. With my tiny energy need and individual workings I mustn’t eat breakfast and I am very passionate about it as breakfast partially ruined my childhood, at least until lunch.
But that’s for 3MAD, right? As it would be 5-8 hours on TMAD…
I always had 3 meals between meals before carnivore, 2MAD was 19/5, 3MAD was 16/8. As I had long meals, often a hour long ones but the time shortens as I eat more times and smaller meals.
I often need to eat more often on carnivore but sometimes I go longer than before so it’s more chaotic. R.I.P. my fixed 3 hours between meals… It never changed on keto either, I just lost my least important meal, I always had 2 main ones and I usually have them even now. It just feels right. Eating before 2pm never felt right starting somewhere in my childhood (and I don’t remember what was before but I wasn’t born doing IF. I merely didn’t eat at night after the first weeks).
I consider it harmful to agressively, forcefully going against our nature, not like I could it regarding eating. I would fight hard and passionately to avoid breakfast. I would sacrifice a lot to protect my sanity, well-being, health and other things.
It’s fine to have a 11 or 12 hour eating window too. Some people eat every 12 hours as that suits them. But there are OMADers eating breakfast and OMADers eating right before bed. Each to their own!
I quickly noticed I need to be well-fasted for my workouts as I have the most energy then.
But I am a morning zombie and I wake up late anyway. So I start my workouts after noon… Works quite well with me being satiated until 2pm at least 
Oh my.
Keto and carnivore were my cheapest diets
Of course I don’t buy expensive things, thankfully I don’t need them. Just a tiny bit of ruminant meat every 2 months, that is still nice even if expensive. But I could stop eating coffee… If I was a different person…
