Antidepressant weight gain


Hi, I'm new here, and I looove these workouts! I was referred here by my doc, when I started gaining weight from a recently prescribed antidepressant. My question: has anyone here been in a similar situation, and found that these workouts will cut thru med-related weight gain? (I'm naturally very slender and have never had to worry about this issue before. I'm ok with a little weight gain, but not this much (15 lbs). I eat well, don't smoke, etc.)
