I am a personal trainer and most of my clients are women and when they ask me about their diet (because they want to lose weight) I give it to them straight.
No sugarcoating...
I tell them what needs to be cut out and what needs to in included.
It's very cut and dry.
......and I would do the same in a relationship.

Div, there is a difference between your personal trainer telling you that you need to lose a few pound than haveing someone who's supposed to love you for "who you are". I dated a guy that had NO problem telling me where something "he felt" was something I shouldn't be eating was going on my body, and did so without haste, without a single thought as to my feelings.......let's just say he's out of the picture and has been for some time.
Caps girl needs to be introduced into the fit way of life on "her own terms". She has to do it for her, not for him. I definitely can understand how when a person's weight effects the relationship "physically", but she isn't going to do it because "he says she's gotten fat". He might say something alongs the lines of "remember that outfit (describe something she looked hot in that she can't fit in anymore), damn you look so beautiful in that. We should go to "such and such place" so I can see you all dolled up in it again and relive that night." Althought she knows she can't fit in it, you have planted a seed in her brain reminding her of how she looked, the heads she turned, how much you loved it AND gives her a thought of "I would love to go to that place again, relive that night, I need to get back into the dress again". At a later date (couple days later) mention that you think you put on a few pounds and things feel a little tight on you and are going to kick up your cardio a bit and change your diet...she may wanna follow suit.
