I have friends that follow this book religiously, but it hasn't really made much of a difference in their health.
I have to say, i have pretty much always been a vegetarian, since I was a child. I always hated meat and I am blood type O.
My sister on the other hand, loves, loves, loves meat and has since childhood and she is blood type A.
I don't know. I think that there are more sensible plans out there.
Just my two cents--
but for the record, I think whatever way of eating that works for the indiviual is the best way. Providing it's not chocolate all day long--
wouldn't that be great, though? If they discovered that eating lots of chocolate was how we were all supposed to live? Yummy!!!
