The Shangri-La Diet

The Shangri-La Diet is both the name of a book by the psychologist Seth Roberts, a professor at Tsinghua University and professor emeritus at UC Berkeley, and the name of the diet that the book advocates. The book discusses consuming 100–400 calories per day in a flavorless food such as extra-light olive oil or canola oil one hour outside of mealtimes as a method of appetite suppression leading to weight loss.
