What an interesting book! In short, it examined our (humans') tendencies with respect to eating: what makes us eat, what makes us enjoy food, what causes our eating habits. Through psychological studies, the author demonstrates that almost all of our decisions about food and eating are psychological and even if we believe we control them, we don't. He presents many cases and analyzes many different scenarios, all of which are very interesting.
Aside from this, the overall premise of the book is to present a common-sense approach to dieting, which he calls the Mindless Diet. Unlike fad diets, which are either difficult or futile, in each chapter he presents several tips based on his psychological research that ought to help people slowly but steadily lose weight with only a small change of lifestyle. I recommend this book to anyone who knows he or she will want to lose a little weight before the summer (even though it is still winter).
