What is Alli?
Alli contains the active ingredient Orlistat. It is the first over-the-counter drug designed to treat obesity. It blocks some of the fat you eat, preventing it from being absorbed by your body.
When taken alongside a reduced-calorie diet, Alli can help you lose up to 50% more weight than dieting alone.
How does Alli work?
Fat Absorption without Alli
Fat is too large to be absorbed by the body
It is broken down by enzymes into smaller parts that the body can absorb
Once broken down, the smaller molecules are easily absorbed by the body
Fat Absorption with Alli
When you take Alli with a well-balanced diet it blocks some of the enzymes from breaking down the fat
This reduces the amount of fat that is absorbed by the body
Larger fat molecules cannot be absorbed by the body and are thus excreted
