I am a very active person, eat healthy on a regular basis and recently started taking Lexapro for GAD. I have read so much information on this site about Lexapro causing weight gain and so far I have actually lost my appetite, and finding myself eating a lot less. Do you think the weight gain is attributed to metabolism in anyway? I have struggled with my weight a lot and finally got to a healthy weight so I don't want to continue if I gain and it is not due to factors I can control. Help!
