I don't know that I buy into "grains" being bad for a body per se. They sure do fatten you up. Whether I am eating a healthy wheatberry salad or a cookie, I can not stop. I think if I could eat grains like I eat meat, I would be able to eat them and lose weight. If I could say, have a burger on a bun and then not need more carbs, a cookie, ice cream....Or if I could eat 1 cup of wheatberry salad and be done.
The funny thing is that the grains most people eat are not healthy even by CW standards. Most people who think eliminating garins is a bad thing (in my world) eat things like bagels, cookies, sugar cereal. Not whole grains. It's like the people who used to tell me vegetarianism was malnourishing me (well OK, it was) but hell, they ate fast food 3x a day.
