Xenical (orlistat) is the medication for weight loss with a well studied mechanism of action. Its effect is based on inhibition of intestinal absorption of fat by blocking lipase. Whole molecules of fat are not absorbed and are excreted from the body.

Xenical inhibits the absorption of up to 30% of fat from food. Due to the reduction in their receipt from outside, the body begins to consume its own "energy resources". Xenical also decreases absorption of liposoluble vitamins, thus consult your doctor as you may need to additionally take a multivitamin preparation containing vitamins (A, D, E, K and beta-carotene).

Information: from a daily diet of 2,900 kcal with fats the body gets 1700 calories. When taking Xenical, 30% of fat absorption is inhibited, that means 510 kcal are burned. For comparison: in order to spend 510 calories, you need to clean the snow for 68 minutes or walk a distance of 14,5 km.

The effectiveness of Xenical was proven in clinical studies, which involved more than 7000 patients worldwide in the past 2 years. Patients who took Xenical for a few months, on average lost about 10% of the body weight. Xenical ensures stable weight loss and prevents subsequent weight gain after discontinuation of the treatment. Weight loss reduces risk factors for diseases such as diabetes, atherosclerosis, and arterial hypertension.

People who take Xenical, do not develop addiction to the drug, thus it can be used for a long time. Medical practice shows, however, that some patients stop taking Xenical after 2-3 weeks of treatment. In most cases this is due to the fact that people expect quick results. Unfortunately, the rapid weight loss without harm to health is impossible: what has accumulated over the years, can not disappear in a week. Reduction of body weight while taking Xenical occurs gradually (on average 1,5-4 kg per month).

Xenical acts only in the lumen of the stomach and small intestine, has no systemic effect, and therefore, has no side effects on the central nervous system, brain, heart and other organs. When you receive Xenical, there is no risk of overdose. At present, Xenical is the most studied medicine for weight loss.
