20/20 diet

Amber • 23. Married to the love of my life. We have a precious two year old names Jacob. I am pregnant with our second blessing. I love natural remedies and a healthy simple lifestyle, but I love cookies. :D
I know dieting is not a great idea when your pregnant. But with the 20/20 diet you are not eating less, your just eating better food with no sugar or crap. I was wondering if any of you mamas have tried the 20/20 diet while pregnant? I gained 50 lbs with my first pregnancy and have not quite lost all of it. I'm 7 weeks and would like to gain as little as possible. Has anyone has any luck with the 20/20 diet?
