The main reason for this is that with food, the body receives more calories than it consumes, that is, a person eats more than he needs. An important source of calories in food is fat, since burning 1 g of fat releases 2 times more energy than burning 1 g of protein or carbohydrates.
Fats contained in food are absorbed by the body only after they are broken down in the intestine by a special enzyme of the pancreas — lipase. Lipase enters the intestine at the beginning of a meal and acts so effectively that all the fats received from food are usually absorbed by 100%. Therefore, as a solution to the problem of reducing excess body weight, the scientists of the company " F. Hoffmann-La Roche " chose the neutralization of lipase.
The fundamental difference between this drug and food additives is that XENICAL is not a mixture of various substances, the mechanism of action of which is unknown, but a drug containing one known active substance orlistat with a fundamentally new, well-studied mechanism of action.
Most dietary supplements have only a temporary effect of reducing body weight, either by affecting the hunger center in the brain, or by increasing heat transfer, or by diuretic or laxative action. Therefore, after stopping taking dietary supplements, body weight increases rapidly, reaching the previous indicators.
1. After starting Xenical, some patients consume more carbohydrates and proteins, resulting in a significant increase in the caloric content of food. At the same time, they believe that "with Xenical, you can eat everything and in unlimited quantities." This is a misconception that can "negate" all the efforts of the patient. Xenical suppresses the absorption of fat, but does not affect the metabolism of proteins and carbohydrates. Unfortunately, the "ideal drug" for weight loss has not yet been created, taking which the patient could not limit himself in food.
2. As practice has shown, some patients who started taking Xenical stop taking the drug after 2-3 weeks. In most cases, this is due to the fact that people expect to get results quickly. Unfortunately, rapid weight loss without harm to health is simply impossible — what has accumulated over the years can not disappear in a week. The decrease in body weight when taking Xenical occurs gradually (on average by 1.5-4 kg per month).
3. When taking Xenical, non-split fat molecules remain in the lumen of the small intestine and mix with the feces. An increase in the fat content in the feces can be accompanied by such phenomena as the discharge of gases, increased defecation, and the stool becomes "greasy". These reactions are not caused by the Xenical itself, but by fats that are not absorbed in the intestine. These phenomena occur when the amount of fat in the diet is limited.
The first drug for weight loss with a studied effect. Xenical (Orlistat) inhibits the absorption of up to 30% of the fat that comes with food.
Due to the reduction of their intake from the outside, the body begins to spend its own "energy resources".
Judging by the results of the intention of fat in the stool, the effect of orlistat begins after a day or two after taking it.
After the withdrawal of the drug, the degree of fat in the callus will return to the level it was before the start of taking the product.
The drug belongs to the group of hypolipidemic agents. It has an inhibitory effect on the lipases of the gastrointestinal tract. It is used to combat obesity or excess weight. The effect of the drug is due to its ability to interact with fat cells, leading to their deactivation. It counteracts the breakdown of food lipases, which blunts their absorption from the gastrointestinal tract, blocks the penetration of triglycerides into the blood.
The drug by its action provokes a lack of energy, triggering the mechanism of consumption of spare fat cells in the body. As a result, with systematic use, the drug effectively helps to reduce weight, but subject to the appropriate diet in the complex. The drug has a positive effect on the level of cholesterol and insulin, lowering them, prevents the accumulation of fat in the abdominal area.
The drug practically does not interact with the plasma when used. Dissolution occurs in the intestine, forming metabolites that are pharmacologically inactive. The drug is almost completely excreted through the intestine. Complete elimination occurs within 5 hours.
The main active substance is orlistat and an additional substance is talc.
The medical preparation is made in opaque solid gelatin capsules of turquoise color.
In the middle of the capsules, the substance is white.

The use of the drug is contraindicated in the presence of cholestasis (accumulation of bile in the liver tissues), in the syndrome of insufficient absorption, as well as in the presence of increased sensitivity to the components of the drug.
Chronic malabsorption syndrome, cholestasis, hypersensitivity to Orlistat and children under 18 years of age.
It is not recommended to combine the use of Orlistat with indirect anticoagulants and cyclosporine.
Pregnancy and breast-feeding are considered relative contraindications to the appointment of Orlistat.
Before prescribing the drug, it is necessary to exclude the presence of an organic cause of obesity in the patient.

In clinical trials, in people with normal body weight, that obese patients, exceeding the regulated dose of the drug by 7 or more times did not affect the overall well-being. Frequent administration of a double dose of the drug three times a day for two weeks was also not accompanied by the appearance of significant malignant phenomena.
In addition, in obese patients, patients with overweight, the experience of using orlistat in a double dose three times a day for six months was not accompanied by a genuine increase in the frequency of pernicious effects.
In cases of Xenical overdose, either no side effects were reported, or no adverse reactions were distinguished from those observed when using the drug in therapeutic portions.
