I'm afraid there's nothing she can do but keep gaining till it shows in the back. Genetic factors determine where the fat goes, you can only control how much it increases or decreases.
crap, I have the same problem. It's not a family thing though. My mom hardly has a belly, but has ginormus hips & a sizable backside. But, on the upside, my legs are much more shapely than hers. My calves are almost completely muscle (but a just noticed a tiny pocket of celulite at the top
gonk ) & my knees are almost "normal."
