My GF is starting to put on a little weight. Nothing too bad, but enough where her clothes are getting tighter and she has a noticeable gut. She sees this and is really upset about it, sometimes will cry when her favorite clothes don't look good on her, etc. She wants to diet but always fails at it. She'll be good for a few days then break it. She is really upset about the weight and really wants to lose it, but cannot keep with the diet. I can't be with her all the time too so I can't help her out too much. Any suggestions on what I can do to help?
