I did not read the whole article, but my take on this is that I don't exclude any foods (except processed and junk food), but my 3 or so months on a Paleo diet has changed my eating. I restrict my grains quite a bit and I eat a ton more vegetables than I used to. Dairy has always been limited for me. I also notice that when I am faced with a recipe that has added sugar, I leave it out. I didn't really see any change in my health, because I already knew what sets my stomach off. In the end, I think a lot of people jump on the Paleo bandwagon because it helps them control their weight. This is the nature of people. Everyone has to find what works for them. I knew I couldn't live without an occasional serving of brown rice or good whole wheat bread, or red wine. But, I have a lot more knowledge now and a lot more good recipes!
