title: By the way, doctor... My problem is the opposite of everyone else I know - I have been losing, not gaining, weight. I am a 56-year-old man, and a year ago I weighed 166. Today, I'm down to 152. I feel pretty good, and my appetite is fine, but I am concerned. I did start to smoke again last year.
