Query: Terrible book

What a dreadful book. I bought this book at the beginning of last year and took on the books advice due to ill health. I have suffered even more illness because of it - my cholesterol levels have sky rocketed, I feel tired all the time and I can't sleep properly at night. I also suffered a stroke mid January. My doctor is terribly disappointed because I ignored her advice to eat less meat products and those yummy fatty foods. I was in fantasy land when I thought that this book would solve my health problems!!!!
