Also I'd take a look as some more options that also have a support system. My wife and I started a program with TSFL and we haven't looked back. It's easy for busy lifestyles and they use a Clincal food program.
We use it in my clinic and I can't believe the results. I'm not too sure about your background, but before you make any decisions I'd like to chat with ya and see where you're at.
In Good Health,
