Girls as far as diet...try a lifestyle like Weight Watchers!!! There are a few of us here that LOVE weight watchers!!! I plan to get right back on it after I have the baby. I was very succussful with it. There is a non-weight watchers website you should check out. This lady did WW and offers tons of info and recipes.
