New and would love to participate in challenge.

I am new to South Beach and would love to participate in this challenge.  I enjoy walking but tend to get sidetracked with my family and household responsibilities.  I started working out at Curves in March and in have lost 3 pounds and 18 inches since I started that.  I struggled during the summer months because my girls were home and I didn't seem to find the time between working and their activities.  I also struggle with eating healthy.  My husband and my girls are picky eaters and I tend to cook the things that they will eat.  I do not want to have to cook different meals so I end up eating what I fix for them.  I am hopeful that I can start eating better and make a better effort at getting out to walk regularly.  I do plan to continue my workouts at Curves three times a week also.
