As a Doctor, I take an interest in what is "out there" on the shelves. Some popular books on weight loss, giving up smoking, stress management, exercise and having a healthy lifestyle send more people in to see me because they all keep saying "see your Doctor if this doesn't work".
Most of these books don't work, because they offer a quick fix.
This book is exemplary in that it explains the scientific rationale behind all the other fads and fashions upon which less scrupulous (and less qualified) authors base their so-called methods.
If you are really serious and motivated about leading a healthy lifestyle with proven benefits, this is the only book you need.
Personally, I wish it did not have such a "cheap" feel about it. I look at the books on the other shelves, with their glossy pages and beautiful pictures and feel that an opportunity has been wasted. If there was ever a book that should be in everyone's house, this is it.
