> 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.
