I'm still reading this book, but the idea of " you aren't so much what you eat, but what you think" really strikes accord with me in this fab book. I'm a long-time Dr. Chopra fan anyway. He is an experienced medical doctor making sometimes unfamiliar or esoteric-sounding Eastern ideas accessible to the West; I also have an interest in natural and holistic living. What we eat, feel, think and do in life is a choice, and they all affect each other, according to this book. If you are out of balance somewhere in your life it will show in your health, and possibly your weight. Your GP isn't a magician and bad food and medical choices can and do make us ill and big companies extremely rich.
Becoming aware of this concept is at the heart of this book. Once your awareness of your diet and lifestyle awakens and your understanding of the mind-body link grows (including how this can affect your weight and the further effects this has to say, to your sleeping habits or confidence-levels), you learn to know you can make helpful changes. You can remove what doesn't serve you, and gradually introduce dietary and other lifestyle choices that balance you and your weight, bringing you health and happiness. I can honestly say Dr. Chopra's ideas work for me, and I'm feeling better for them. It would be great if the NHS adopted these ideas rather than spending billions on treating symptoms.
As the book suggests, it's not a diet book per se, but one about changing your mindset related to food, using both Western and Ayurvedic medical philosophies. If you don't want to be seen as a hippie, it might not be for you, but if you're open-minded or like Deepak Chopra's other work (there's a lot of it!), give it a read. It's practical, positive and accessible reading. If you'd rather try an entirely non-Eastern approach to the same kind of things, then I'd recommend Paul McKenna's hypnotherapy and NLP-based work instead.
