Query: Shallow Book

The author offers a one-dimensional opinion as to why Japanese women are thin. The traditional Japanese diet is only part of the answer. Cultural pressures in Japan to be thin are overwhelming. If you live in Japan and gain so much as one kilogram, you'll hear about it before the needle on your scale can even register it. Both men and women watch every bite of food a woman eats in public. At the workplace eyes will roll knowingly if a woman eats four small rice balls for lunch. Conversely, women are chided or quized about "being on a diet" if they consume only two rice balls. The incidents of eating disorders is skyrocketing in Japan. Underlying everything is a feeling of superiority about being thinner and more youthful than people of other countries and cultures. Witness the title of the book itself. The title alone rates a zero in my mind.
