<human>: My long distance girlfriend of 8 months suffers from what she describes as "food guilt." In short, several times a week she'll message me expressing varying degrees of anxiety over what she has eaten. She is NOT overweight (5' 7'' and 137lbs), eats very well, and exercises frequently. 

Most recently, she sent pictures of other girls wearing bikinis (girls that she knows personally and others that she knows I'd hooked up with before our relationship) and expressed regret over eating bread, pasta, and Clif Bars in the last week. It's difficult to convince her that she's exercising enough (she'll go to practice for a varsity sport and be upset that she didn't go for an additional run afterward), and she doesn't fully believe me when I tell her that I find her body very attractive. 

I try to climb, lift, or run about every day. She says I deserve someone that "looks as good as I do," but I cannot convince her that she is that person! We're planning a 200+ mile hike for the coming summer--clearly there is a disconnect in her self image and the reality of the situation (that she is in great shape!).

Her mother struggled with bulimia in the past and continues to have issues with body image. My girlfriend has also admitted to trying to make herself vomit (unsuccessfully) in the past but has promised she hasn't during the duration of our relationship. I believe her, and I think the physical extent of her problem is limited to diet and exercise.

Should I suggest she talk to a therapist? We're extremely close, but I'm worried she'd dismiss that as unnecessary. My thoughts are that a toxic previous relationship (ex constantly degrading her appearance) and family history have created a situation that is only exacerbated by the distance.

Can you provide a brief overview of the text?
<bot>: My beautiful ldr girlfriend gets anxiety over eating anything that might be considered remotely unhealthy despite being in great shape. Nothing I say seems to help. What should I do?
