Yes, I do think so. But this doesn't mean I would dodge her for not paying attention to her body. Looks are nice, but I don't think it can differ my feelings for her.
I'd say that I am very happy when she exercices or does sport with me, it shows that she wants to do her best. EVEN if she doesn't get to the look she wanted, I appreciate the effort very much.
By the way, the aclual body isn't the only factor, there's also the way you dress; it can change a whole lot.
(that's one man's opinion.)
