I actually found very little of it their personal opinions. Most of it was direct scientific evidence, facts about legal proceedings and facts from the doctors that contributed to the book. Anyone who reads a diet book, no matter which one should consider that it may not meet their specific dietary needs.
I have to disagree about the deprivation. I'm all about avoiding feeling deprived and I'm a big girl, I can see where they're coming from but use my own mind as well. They also state that they're not perfect and don't follow it 100% of the time.
It wasn't their opinions that convinced me, it was the science and the actual physical evidence. The only opinions I perceived is 'you are what you eat' that was expounded upon and their feelings about humans drinking the milk of another species being strange. Which is why I'm not sure about dairy still.
Other than that, the slaughterhouse accounts (which i had only knew a tiny bit of previously when I stopped eating red meat for 5 years) and the legal corruptness of the meat and dairy industry (actual facts). Those were not opinions. Those are things I did not know but make SO much sense to me now.
As I said, I will absolutely talk to my HK woman about it but all I know is I feel SO much better already. I'm an animal lover and there's just no way my conscience would let me put that into my body again. Maybe my feelings will dull over time, I don't know but I just couldn't ignore the facts.
