I'll never be my ideal weight.....?

I've wondered about this too, but I think the idea is that you will lose some lean mass along with the fat. You don't really know what your lean body mass is going to be at goal. Lean body mass includes anything that isn't fat, so not just muscle. I would think that it's likely to get a little smaller as you get smaller, even if you preserve muscle. For instance you might not be carrying as much water, blood, etc. (I don't know if that's true, but it's what seems to make sense to me!).

That's accurate. LBM will decrease with her weight loss. If she drops a few stone and gets a reliable bf measurement, she'll be able to re-assess with more certainty.
