Wow….It’s really hard to formulate a supportive response here. I HOPE the reason that you are encouraging the healthy changes in your girlfriend’s lifestyle to promote good health, not merely some shallow conception of beauty.

Some people do not enjoy physical activity, and the more you nag, the more they resent it and another bag of Doritos is opened.

What is more important than your view of her is her own. She will only make changes when she wants to. A person cannot make an alcoholic or drug addict stop the abuse, even with the best of intentions, it must be the individual. The same holds true for over eating.

Out of curiosity, if she was in a car accident tomorrow and was disfigured, would you stop seeing her? If your relationship is based solely on her appearance then it isn’t going to last. My husband and I have been married for over 21 years now. When I look at him, I still see the 18 year old I started dating. In my mind he has not aged and the changes are only for the better, and none of them include any outward appearances. But I have been told he’s “hot” (hate that word, makes me think of a bubble headed Paris Hilton) on more than one occasion.

I’d like very much to give you more advice, but I’m sure this post would be removed for being unsupportive.
