How Does Orlistat Work?

When you eat, the dietary fats in your food have to be broken down into smaller pieces before your body can absorb them. When you take Orlistat, it works by blocking the enzyme responsible for breaking down those dietary fats. As a result, your body isn’t able to absorb all of the fat, and the undigested fat simply passes out of your body through bowel movements. This prevents your body from gaining as much weight as a result of ingesting fat. However, Orlistat does not block the absorption of other calories, such as those from sugar and other non-fat foods, so it’s still important to reduce your caloric intake if you wish to lose weight.

How Much Weight Can You Lose With Orlistat?

The specific amount of weight you'll lose with Orlistat will depend on several factors, including your starting weight and for how long you take the medication.

How Do I Take Orlistat?
