I wanted to loose weight before getting pregnant so I bought the wii and the biggest loser game. I worked out and stopped eating all the junk I was and I lost 40 pounds in two months. I managed to keep most of it off even after having a baby. I am 4 pounds away from my pre-pregnancy weight and he is 3 weeks old.
Support, support, support and keep up with it. It is hard but well worth it.
