Can you still lose weight while on steroids?

singtonations

I have something called Dermatomyositis which is an inflammatory muscle disease. Althought its hard on my limbs and joints I exercise hard: kickboxing, aerobics, walking etc. I stay way under my calorie intake daily. Should I still see results and be able to lose a subtantial amount of weight even though steroids are known for keeping you hefty? If so, how? and what are some suggested safe ways to exercise?
