In the past, Isadora being huge was a byproduct of her daughters messing with magic and reality on themselves, with the new-ish set up for Alexandria and zenithification, is this still true? And is Isadora aware of this consequence or are her memories altered with the changes to reality? Do her daughters know, and just choose not to tell their mom?
It's a bit different now, but still kind of accurate? The way things are now, both Lyssa and Isadora are changed when Vivi is altered by Xandria, both in terms of Deva women trending towards ridiculous sizes and the whole elf thing. Both Lyssa and Isadora are generally unaware of how things used to be prior these changes, even if Lyssa eventually gains some influence via her whole deal with Pietra. Isadora, likewise, gets to know a little about the nature of Xandria's influence and all that, but has no memory of how things used to be prior to the altered reality. As far as she's concerned her size is just genetics, a curves-enhancing enchantment she put on herself many, many years ago that just... never stopped enhancing, and an overactive appetite. :V
Vivi is generally aware that she's the reason her family is like this now, as is Lyssa, but neither bothers to tell Isadora because shit is weird (and she has her own experienced version of reality and there'd be no point in telling her the truth)
