this is one of my favorite reasons for losing weight. i'm not really looking to have kids for a few more years (i'm only 20) but i've always wanted to have a few kids and i just want to be a cute preggo woman and feel all glowing and not feel like a whale. i'm sure toward the end everyone feels like a whale, lol, but it can't hurt.
besides, if i am already living a healthy lifestyle, then i won't have to worry about trying to change my diet all that much when i do get pregnant, or during the fun trying stage.
