How careful were you with your diet while pregnant?

I was very careful with my first pregnancy. I tried to follow my pregnancy diet to the letter. About once a week, I got tired of denying myself and ate a little bit of something sweet. In spite of that, I gained 55 pounds with my first pregnancy. The second time, I went ahead and ate dessert about once per day. I only gained 48 pounds that time. It actually sounds like she is not following a pregnancy diet.
