How do I deal with girlfriend weight issues?

Anonymous
My girlfriend has put on a little weight in recent months. She used to be very thin a few years ago, and now most of her clothes don't fit anymore. We started the relationship when she was already less skinny so its not an issue to me, but to her it is a big deal. She feels bad about it and the subject comes out in conversations quite often, brought out by her of course. I honestly don't mind, but I honestly don't know how to respond. I used to tell her I thought she was beautiful (which I do), but she always shut that down telling me I was just saying it because I didn't want any trouble. I quickly changed the subject after that but then she got a little upset because I stopped her from venting out. SO I stopped doing that also. My current behavior involves not saying anything , let her talk about her weight problems a little and then hug her, kiss her or a combination of both, and hope she gets distracted and then change the subject slowly. So far so good, but I'm afraid this way is going to backfire in any moment. This is the first time I'm with a girl like this. I love her very much so I don't want to hurt her, so I would like to get an input from girls about this. Thanks
