A friend of mine has mild anorexia (she's on psych meds to keep it contained) and recently asked me some advice about working out. She told me that she is mainly interested in not being so skinny. I offered to work out with her one day of the week to make sure she's going about things correctly, with proper form and everything.

The thing is, just going to the gym and working out isn't effective if her diet and sleeping cycle aren't also improved. I would normally be really blunt about these other facts, but her dealing with anorexia probably complicates things a bit... especially the proper diet part. I was thinking that if she has trouble eating enough, maybe she could try drinking some protein shakes. But I'm not sure if that would actually be effective in helping her reach her goal of putting on more weight if she's not eating properly other times of the day. If anyone has any advice on how I could more effectively broach that subject without being insulting or belittling I would appreciate it.
