Query: Become a vegetarian and save yourself the trouble of buying

this book. I don't understand the other reviewers, it's as if we received two different books. I am well read on food combining, fasting, vegetarianism, etc. and found this book to be one of the worst. Negative calories is a plausible concept but don't look to this book to really help you. You'll feel ripped off just by thumbing through the book. Just eat your veggies and cut out all that red meat and you'll do wonders for yourself.
