Just to be the odd man (woman) out, I've been on prednisone for almost two years straight and have not noticed any increase in hunger. I also had not gained any weight until the past few months, but that is because the arthritis has been so bad that I've had to stop working out completely (went from working out a lot to doing nothing, so I'm up about
6 lbs). I seem to be one of the few that didn't gain weight on it, but also haven't gained from a few other meds that normally make people gain, so I guess I'm just really lucky (and I'm sure the fact that I used to work out 11 hrs/week really helped).
