What we're about to describe will change the way you think, and that will change the way you eat, the way you exercise, the way you look, and the way you feel. But first, let's start with an overview of how your body burns and stores its fuel. The human body, for all its wonderful complexity, acts much like a machine. Unlike ordinary machines, however, your body can accept a huge surplus of fuel by converting it into an on-board energy reserve known as fat. All weight-loss diets work by making your body burn off this reserve instead of adding to it.
Diets differ only in how they tune the engine.
These all sound very clever. Yet only ten percent of people who diet actually keep the weight off. DietPower No diet can succeed if you lose weight too fast. When you starve the engine of fuel, it responds by giving itself a tuneup that increases fuel efficiency. Suddenly, even the skimpiest meals begin feeding your fat reserves.
