Re: What does this mean
If she has any dietary variation, 5 pounds of water isnt unheard of, especially if she's had anything high in sodium lately. If she's not doing anything new as far as exercise, it's very unlikely it's muscle. 5 pounds on a lean frame won't cause a hugely significant clothing-fit difference either, so some of it could be muscle or fat too.
