No worries, it makes sense!
It’s not that it’s less optimal just that there are ratios that I think are pretty much just as optimal and when you factor in that people will not eat a diet for the rest of their life. If they can’t adhere to a diet then it doesn’t matter how good it is which is a big difference from animal studies. Off the top of my head the Mediterranean diet is a good example but it this doesn’t have to sit in one of the blue zones.
Yes I agree.
