Orlistat (Alli) CAS NO.96829-58-2

Orlistat is a pharmaceutical drug, sold over-the-counter under the name Alli, and under prescription as Xenical.

 

This weight loss pill works by inhibiting the breakdown of fat in the gut, making you take in fewer calories from fat.

 

According to a big review of 11 studies, orlistat can increase weight loss by 6 pounds (2.7 kg) compared to a dummy pill. Orlistat has been shown to reduce blood pressure slightly, and reduced the risk of developing type 2 diabetes by 37% in one study (14, 15).

 

It is usually recommended to follow a low-fat diet while taking orlistat, in order to minimize side effects. Interestingly, a low carb diet (without drugs) has been shown to be as effective as both orlistat and a low-fat diet combined.
