> But if some of that weight was actually muscle, or some other important tissue, then no, I don’t like that at all. And I’ve no idea how to tell. I don’t feel noticeably weaker, I guess?

Ha, welcome to the big mystery that is as of yet unsolvable (insoluble?). No, even DEXA scans can't tell you this in any meaningful way, since water is "lean mass."

So you're wondering the same thing that every honest nutrition scientist out there's wondering..

By the way it could just be that your body is adapting to getting into/out of ketosis. The first few times it happened for me, it was very noticeable in either direction. These days, I feel zero keto flu or "feeling" or cognitive stuff or performance when I go in/out, but I do lose/gain 5-10lbs lol. Depending on what I eat.

Maybe your body is just recognizing what's about to happen and adapting much faster in some sort of "Sheeeet here we go again" mode.

I suspect that healthy neanderthals got into/out of ketosis all the time; seasonally, daily, weekly... they might've even been in ketosis for part of the day while hunting fasted, then maybe come home and gorge on whatever was killed/gathered that day, kicking them out until the next morning.

I agree, if you substitute 'neanderthals' with 'ancient humans'. Non-Africans do have a little bit of neanderthal ancestry, and we've probably got some interesting things from them, but I've never heard that ketosis works differently in black people so all that is probably coming from the main line (probably from both actually, it looks really old and is likely from the common ancestor).

On the other hand, it would be very interesting if it did work differently in Africans, and we might not know unless we'd gone looking for it. Are there any black keto-gurus?

Yea I've never heard of a difference there either, but not sure. I know black carnivore gurus, but not black keto gurus I think. Then again the # of keto gurus is relatively small.

If I was right about the sulphites thing I may not have had much in the way of keto flu at all, and it wouldn't surprise me if I'd got used to it. Apart from the second go it was never particularly bad.

But the previous 4 times I predictably lost and regained 1.5kg or 'water weight' in a couple of days, which is in nice accordance with the water-bound-glycogen idea. This time it was different. Quite a lot more transient loss and gain. I'd love to know what the difference was.
