Just! Lose! Weight!  It's just so amazing that something so minor is apparently beyond them. I'm around a pretty large amount of severely sick people. And weight loss is just part of the territory because hunger is right at the bottom of the pain or discomfort scale. It's a pain so minor most of us don't even really notice it and have to remind ourselves about the whole "taking in calories to stay alive". The most minor issue we have on a day to day basis is STILL too much for them to deal with.
