They say is goes without saying but being obese and becoming pregnant and not wanting your baby to suffer cause you're fat or not wanted to feather aid your obese-ness. I imagine a few other ladies have or will have the same ideas as me so I wanted to post this and help some other girls out. I did diet, I did loose 10lbs, and my dr did yell at me. It's not safe, save it for after baby comes if you must. Just eat healthy, walk, swim, dance and know that you baby needs you to gain weight right now. Let your dr worry about your weight and you worry about what you're feeding you baby through yourself.
