Going through the same thing and I want to lose 40 lbs too... Best of luck?
I am a 182 lbs, female, 30 year old Acute Lymphoblastic Leukemia (aka. ALL, a blood cancer) survivor... I went through a bone marrow transplant and now I have chronic Graft vs. Host disease which had lead to stiffening of my joints and constant cramping... I have also been on a steady regime of steroids for a little over 2 years (which make me blow up like a balloon...lol..)... So my weight loss goal is 40-45 lbs., but over all more flexibility everywhere, and gaining some of my strength back is what I am really after. The rest will come with time.
I meant: best of luck! :)
