For those of us who are overweight to begin with, do you have any plans for minimizing weight gain and such? Reflecting upon my pregnancies before, I only gained 35 lbs. each time, but my diet really wasn't the best at ALL. So this time I'm considering adopting a sort of GD-type diet to help my metabolism out, as well as doing SOME form of exercise daily, even if it's just walking. I'm a working-full-time-RN, so I'm on my feet all day long, but it's not the same as exercise. Any other thoughts?
