Drug Class and Mechanism Alli
Alli blocks about 25% of the fat you eat. Typically, enzymes in your intestines break down fat from food so your body can absorb the fat. But, the active ingredient in Alli attaches to some of these enzymes and prevents them from digesting about a quarter of the fat you eat. Because undigested fat can't be absorbed, it passes out of your body instead of turning into calories.

Many individuals really need help with their dieting and Alli can make them the whole process a lot easier, since alli is not just a diet pill, it's actually a weight loss program, a plan to follow, a way to learn how to eat healthy and how to do healthy things for their body, to feel and function better. The one thing that Alli does very well is that it teaches you how to start eating low-fat foods, because Alli works with fats in your body. It blocks them from being absorbed by your digestive system and when that happens, your body does not store fat anymore; it gets rid of it effectively, through your digestive system.
