How can a paraplegic lose fat in their legs?

I have a friend who wants to lose some fat, especially in her legs but she is a paraplegic (paralyzed from the waist down). How can she lose the fat when she can even move her legs without surgery to remove the fat?

You can’t target where you want to lose fat. She could try reducing her intake of calories to lose weight overall, and that may reduce the fat on her legs. Can a physical therapist move her legs in some form of exercise so the muscles don’t atrophy and her legs tone up? I’m not sure how that works with paraplegics.
