You can also use DietPower with Meridia, Xenical, and other weight-loss drugs. It maximizes any weight-loss system, because it exploits a feature that every diet must have. 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 onboard 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 most people who lose weight fail to keep it off permanently. No diet can succeed if you shed the pounds 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.
