Honestlu, I think there’s a tendency here, not surprisingly, towards ‘when you have a hammer, everything looks like a nail’ thinking. In that people tend to think insulin is everything, which I don’t actually think is the case.
That’s not crucially, to say it doesn’t matter, and isn’t often very important or most important. But there’s lots of other stuff, I think. But that’s not keto specific - Stephen Guyent seems to think it’s ALL about palability (as it goes, I suspect hyper palatability is part of it)
In my case I don’t think insulin is a major driver of how much I eat, although it’s probably an issue of how I process those calories. I think this because I’ve used, at various points, both exogenous insulin and drugs that cause my pancreas to shoot out extra insulin.
And the amount I eat seems disconnected from that. Point in case, I’m off all insulin enhancing stuff AND I’d been fasting, and yesterday I ate 5500 or so calories. Short of taking actual fasting insulin tests I am as confident as I can be that my insulin is as low as it’s been for a long while. Still ate a whole bunch.
Which is fine, as it goes. And I wouldn’t generalize my situation to others. I don’t really have either hunger or satiety responses, which is, obviously, a mixed bag. But in my case, since I can pretty much eat until I am physically unable to, I have the psychological drive to do so. I don’t, usually, which is why I don’t weight 280, but I’ve never experienced any diet mechanism that actually changed this, from carb restriction to fat restriction to protein restriction to everything restriction.
