I am the old plan "off the books" too. I am on red without lites. Believe it or not, I got sick of eating so much sweet stuff with the bars. I am doing 2.5 protein, 4 or 5 veg, 3 fruit, 1 dairy, 1 fat, 3 starches. If you don't have access to the bars I believe you can bump up your "real" food to the next plan. Katie would know more about that.
You can do it away from the center. YOU CAN! I have done it before and now that I am losing baby weight I am doing it again (this time my hubby is doing it with me). It is just healthy food in normal portions so you learn how to eat. It is a lot of cooking and not a lot of processed/restaurant food...that's the hardest part for me since I am the family cook.
