You can do it yourself! No need for a diet center. They charge about 3 x's more and really are not that helpful. Just order online! You can do it. I have a coach, but find she's really not that helpful. I think it just depends how motivated you are. Watch all the videos on YouTube! There are great coaches and lots of helpful hints. Plus, you found us here and we are ready to cheer you on.
I've been on for a little over 2 weeks, and have lost 15# with no exercising yet. You can do it! It is well worth spending the money on the food. Just follow the plan.
