With the long term stabilization thing--yeah. That goes for nitrogen balance studies, too, habitually high protein takes mean that something has to be upregulated to clear all those amino acids coming into the system. I think most of the data on the low end of glucose requirement comes from starvation studies, and most of the data on the high end of glucose requirement comes from studies of people eating higher carb diets, and as usual, we don't really have enough data

I also agree that this topic is something that is not as solidly understood and scientifically clear (in particular in the context of a keto-adapted person) as many of the keto/HFLC people state it to be.

As a keto/HFLC person, I'll throw in that I don't think it's as solidly understood as the non-keto people state it to be either. It's anybody's game. Anecdotal evidence does show people not exactly wasting away due to eating less than enough protein to support that 130 grams of glucose a day figure.
I don't know if you've read The Ketogenic Diet by Lyle McDonald. That's a few years back... but there's a section where he states that early on, a model 150 pound male can achieve nitrogen balance on the ketogenic diet on 150 grams of protein. After a three-week adaptation period, he suggests that same person could retain his lean mass on as little as 50 grams of protein. (His actual protein recommendation for that 150 pound male is 120 grams, but then, the book is geared towards bodybuilding). But he relies very heavily on fasting studies, rather than ketogenic diet studies as references when he's writing about absolute glucose requirements.
