i recently started the low-carb thing so my bf isn't a problem but before that, i was doing low-fat.... he was very mean and would pick on me.. even about water "make sure your water is low fat lizzy!" yeah, i dumped him..

tell him how you feel.. tell him you are trying to look better for him.. thats what i did.. the X and i are "dating" again. and now that im low-carb.. he doesn't make fun of me.. maybe because i gave him a piece of my mind!
