Nope. I was one of those who gained massive amounts because of treatments. I went from 155 to 112 because of the lymphoma and then up to 232 because of chemo and overeating. Everyone who came into that damn hospital room took one look at me at 112 and started stuffing food down my pie-hole They meant well but I really don't think anyone believed I was going to make it so the just said WTF.
