How does Xenical work?

Imagine your stomach is a parking lot and cars are fat. Without Xenical, fat is free to take up all the spaces, and be absorbed into your system. With Xenical, a third of the spaces are blocked and the fat has to move on because it can't park in your system. The fat that is not absorbed is passed out in your normal bowel motions therefore helping you control your weight and achieve your weight loss goals.
