I'm not sure. My info says "whole-wheat pasta or brown rice or potatoes is limited to one meal a day." And then at the bottom, it says "Puffed wheat, puffed rice, shredded wheat, and 100% bran cereals that do not contain added sugar are limited to one meal a day and must be eaten with fat-free milk or fat-free plain yogurt."
So ... I'm taking that to mean, since they're mentioned separately, that you can have cereal in the morning, and then WW pasta or brown rice, or any of the Core grains such as barley, couscous, etc. in the evening. I'm sure someone will correct me if I'm wrong though.
