Xenical is a fat blocker diet pill and is only available via prescription.
In order to take Xenical you have to be assessed by your doctor, this is usually done by looking at your Body Mass Index or BMI.
Unlike some diet pills that supress your appetite, Xenical works by blocking about one-third of the fat ingested in the digestive tract through the active ingredient orlistat.
So when taken with meals Xenical attaches to the enzymes in your digestive system and blocks them from breaking down the fat. The undigested fat cannot be absorbed and is subsequently eliminated in your bowel movements.
How does Xenical work?
Extensive studies on Xenical have shown that almost twice as many patients taking Xenical lost on average 10 percent or more of their body weight compared to those only on a diet.
Xenical side effects
Xenical can cause diarrhoea (and flatulence) due to the elimination of undigested fat from your digestive tract. For this reason it is normally recommended you follow a low fat diet to prevent such symptoms.
Recommend Xenical for weight loss?
Xenical is usually recommended only for those who are overweight or obese (BMI of 30 plus). Difficulty in obtaining Xenical and the reported side-effects make us want to recommend more effective diet pills.
