I've talked to my T about it but received muchore help from my pdoc. I was on an MAOI for a while and went from 133 to 165, and I am only 5'2. My T didn't meet me until I was heavier so didn't put as much emphasis on the med and instead went over the self care, diet and exercise stuff, which I found frustrating. I've struggled with EDs in the past and this weight gain was very upsetting and triggering. My pdoc tried everything to help so I could stay on it as it worked wonders for my mood, but eventually took me off and switched me to Prozac. I was insistent that any med I took needs to not cause weight gain and he assured me it is the most weight neutral of all the SSRIS. I've been on most of the others, and I have found it to be true (I lost all the weight in about 6 months). So I'd talk to your T about your worries but more importantly your Pdoc, make sure you are firm about your concerns because the weight gain tends to be played down in the research on antidepressants. I ask my doctor about his patients experiences for reference.
