I don't mind the glucose just being there if it isn't damaging my tissues. Of course I have no idea if that's possible.
Don't worry about that source question. That was the first time I had seen that, and yet I've seen that "fat cells filling up with water" narrative for years. Right after I read yours, I read it again, and with some decent level of attribution. It really doesn't make much sense for fat cells to do that.
