FWIW, JM looks less like he is on deaths door lately. His skin color is darker, suggesting his anemia is corrected. TBH I think he is back on hormone replacement/ TRT. He's growing a beard and his piglet face is not so soft. Personally, I suspect he went back on TRT so he wouldn't lose absurd amounts of lean tissue during his anticipated starvation ventures.

I like this part--she thinks Jimmy looks better since he's been fasting, better enough that she thinks he must be on testosterone.
I think we need a period of refeeding, and another dexa, before saying that he lost half of his weight on the fast as muscle.
I'd have to go back and watch the video for his dexa before the 30 days fast, but I seem to recall him saying at that point that his lean mass showed as being 10 pounds higher for lean mass than his previous dexa scan that he did after a long time on nutritional ketosis. He did two previous extended fasts, between these two dexa's, I think they were both 17 days long, with extended periods of refeeding after each, before that 30 day fast.
Nutritional ketosis, lean mass equals X
Seventeen day fast, refeed, seventeen day fast, refeed, lean mass=X+10
Thirty day fast, no refeed, lean mass equals X again.
I do think she might be right about his insulin sensitivity--his fat cells are likely fairly sensitive to insulin, this is a problem when fighting obesity. At the same time, these things are relative. Liz and Jey report fasting blood insulin levels in the low single digits, Jimmy's insulin levels are in the mid-teens. Not that high, but enough of a difference to be considered a risk factor, and a pretty high insulin level for a non-diabetic who's been on a ketogenic diet and done as much fasting as he has.
Very insulin sensitive fat cells might mean that only a very slight systemic insulin resistance (liver etc.) might be necessary for insulin to be high enough to prevent weight loss.
