In the beginning of April, 2005 in Annals of Internal Medicine was results of comparative studying of medicinal, dietary and surgical methods of growing thin which was financed by governmental body U.S are published. Agency for Healthcare Research and Quality.

Alas, results have appeared not in favour of numerous free weight loss diets and medicines. Scientists from several medical cents have spent the review of 225 researches devoted to application free weight loss diets, medicines and surgical operations for growing thin (imposing of the bypass shunt of a stomach or an adjustable gastric bandage) for adiposity treatment.

The analysis of methods of growing thin has shown:

When the patients, suffering adiposity, were exposed to the operative treatment directed on reduction of volume of a stomach, for 10 years have lost from 20 to 30 kg and supported it at the reached level. Not only that operative treatment has helped to lower weight of a body, at the majority of patients it still promoted simplification of a current, and sometimes and to disappearance: a diabetes, the raised arterial pressure, episodes of night respiratory standstill, infringement of an exchange of cholesterol. Average cost of such operation in the USA makes 26 thousand dollars. Frequency of deadly outcomes during carrying out of the operations directed on decrease of weight of a body did not exceed one percent. Thus communication between qualification of surgeons and frequency of complications, death is accurately traced. Death rate and complications most often met when the surgeon who has made less of 50 similar sorts of operations operated.
People who for decrease in weight of a body were on special free weight loss diets, accepted medicines and regularly were engaged in physical exercises, have lost for a year from 7 to 9 kg. However in all analysed researches of a similar sort, studying of the remote results of spent actions that allows to assume their short-term efficiency was not spent.
The drug intake also was accompanied by certain adverse effects. So, application sibutramina, a brain influencing structures that leads to sensation of satiety, was quite often accompanied by increase of frequency of warm reductions and arterial pressure. One more preparation, orlistat, blocking in a digestive path of fat arriving with food, caused various problems.

It is important to notice, that "modest enough" efficiency free weight loss diets, medicines and physical exercises it has been revealed only at people with superfluous weight of a body and moderate adiposity. When excess weight made 45 and more kg, conservative treatment has appeared insufficient.

Results of this research can affect a policy of the insurance companies paying treatment of patients in the USA. After all now, operative treatment on weight reduction is paid only to those fat men who except adiposity have still a diabetes and-or cardiovascular diseases.

On the basis of data of the analysis of the scientific researches devoted to a problem of decrease of weight of a body of patients, American College of Physicians recommended medicines and surgical treatment only to those patients who have not coped with a problem of decrease in weight of a body by means of traditional free weight loss diets.

According to Thomas Wadden, the director the Weight and Eating Disorders Program at the University of Pennsylvania in Philadelphia, for popularisation of effective methods of struggle against adiposity it is necessary to spend the companies which on the scale should not concede such known as struggle against smoking, car driving in a state of intoxication and AIDS preventive maintenance.
