This is a very, very restricted diet, yet very much not a fad diet. It's actually backed by science, and Doctor Ornish actually is well known in the medical community for being able to reverse blockages to the heart using diet, instead of surgery or drugs. So this actually isn't snake oil, but roote...
This was my introduction to the idea of lowfat/high bulk eating, and for that I will always be grateful. The text portion of the book is easy to read and understand.Unfortunately, you'd have to have a full-time cook and lots of money to get much use out of the recipes!
