I have that cookbook and our coach has never told us something in it was not protocol. You do need to be careful with doing tomatoes too often, but I use that book every day. My husband has lost close to 90 pounds. I’ve lost 30 (my goal) and am maintaining. I don’t think it’s necessary to be so legalistic. The program works, but we are more interested in the life-style change. If that means it moves a little slower because we throw a little tomato paste into a recipe every now and again, we’re okay with that.
