If you have been fighting obesity and are unable to lose weight through conventional weight loss methods such as dieting and exercise, you can take the help of Xenical diet pills. Marketed by Roche pharmaceuticals, Xenical orlistat is one of the most prescribed weight loss medications today. Xenical diet pills are even approved by the US Food and Drugs Administration (FDA); this means that the medicine is clinically proven to be safe and effective. Xenical was launched in the year 1999; millions of people have benefitted from this diet pill and achieved effective weight loss. Studies have proven that Xenical pills can help you achieve a weight loss of 5-10% in 6-10 months time. Experts believe that for an obese patient, a weight loss of even 5% makes an immense difference. It can prevent a person from developing serious conditions linked with obesity such as high blood pressure, high cholesterol and diabetes. In addition, this significant weight loss will help you feel healthier and more active.

Xenical orlistat works with unique mechanism of action. Unlike many other diet pills that work on your brain to curb your appetite, Xenical works in your digestive system to reduce the absorption of fat in your diet. The active ingredient in Xenical is called orlistat; it works as a fat absorption inhibitor weight loss drug, belonging to the class of medicines called lipase inhibitors. Once taken, the weight loss pill reaches your gastrointestinal tract where it attaches itself to enzymes called lipases which are responsible for the breakdown of fat into simpler molecules that can be absorbed by your body. Orlistat prevents the action of lipases and thereby prevents a part of the fat in your diet from being digested. The undigested fat cannot be absorbed by your body and is eliminated out of your system through normal bowel movement. By working in this manner, Xenical diet pills can prevent 1/3rd of the fat in your diet from being stored in your body. As a result, your net calorie intake is reduced and you lose weight faster. However, Xenical will help you achieve weight loss only if you take a reduced calorie diet and regular physical exercise.

As Xenical is a prescription only diet pill, you will need to consult your doctor before using this medication. Remember that you inform your doctor about your medical conditions and medicines that you may be taking. Typically, doctors prescribe the 120mg Xenical pill to be taken thrice a day with every main meal that contains fat. In case, you occasionally miss a meal or take a meal which does not contain fat you can skip that dosage of Xenical. Your doctor may also prescribe you a fat-soluble multi-vitamin pill once a day that must be taken at least 2 hours before or after taking Xenical, such as at bedtime. This is essential as Xenical treatment may reduce the absorption of some of the fat-soluble vitamins in your diet.
