Imagine a diet that's as easy as "a spoonful of sugar" (or extra-light olive oil) twice a day. A diet that actually reduces appetite and cravings. A diet that's based on a wealth of scientific findings but is simple enough for anyone to stick to. A diet with results that amaze almost everyone who tries it.

Based on a new understanding of how the human body regulates hunger, The Shangri-La Diet presents a strikingly simple and surprisingly effective way to lose weight-without giving up favorite foods.

Simple and counterintuitive, this extraordinary new diet is changing the way the world thinks about weight loss-one success story at a time.
