How does Alli work?

Andrea Giancoli (Registered Dietician ) gives expert video advice on: What is Alli?; What is the history of Alli?; What is the promise of Alli? and more...

Alli works by blocking digestive enzymes that break down fat in the gut. By blocking those enzymes, you are not going to be digesting so much fat, and that is then going to be coming out and you are going to be excreting it. Therefore, you are excreting calories.
