In a very simple way this book shows the relationship beetwen what we eat and our behaviour. The way we think, the way we act and the way we crave for certain foods. And the most important, it shows how to regulate the way we eat, giving the reader the tools for it - not just a bunch of 'easy' formulas. It is one of the best pictures to that ancient chinese expression that states: "if a man comes to your door asking for food don't give him the food, teach him the art of fishing". If you are looking for abracadabra formulas don't buy it! But if you like inner travels in the search of knowledge and undersatnding of your own person by your own hands, it's a five star's choice.
