When someone looks too thin do you tell them?

Yesterday at the gym I noticed just how skinny one of the women has become who takes zumba with me. She looks anorexic. I ran into her after class and I said to her, “are you ok, you lost so much weight, you’re too thin.” now, keep in mind this woman is jumping around in zumba 5 days a week, so I was pretty sure she doesn’t have cancer or AIDS. If I thought she might actually have a very serious physical illness I might not have said anything.

I say something to people who look anorexic, because part of their problem is they don’t know how thin they are. She actually said to me, “I just started to realize I actually am thin now, you know it takes a while for your mind to adjust when you gain and when you lose.” She is skin and bones.
