American scientists announced that they found "medicine" for those, who lose weight and gain it again after a while. This problem is actual for 85% of those, who try to get rid of excess weight.

Lot`s of people can reduce weight, one must sit on one of numerous diets. They are all based on one principle: to eat less calories than spend. Some people struggle with excess weight for years and then gain it again with damage to health.

But group of scientists from Columbian university (New York, USA) discovered that injections of natural hormone leptyne can persuade body that is must not accumulate fat and keep it on certain level.

Leptyne is produced in fat cells and purpose of hormone is to signal about level of fat reserves in organism. Deficit of leptyne means that reserves of fat run down and human eat more to fill losses.

During experiments with volunteers scientists discovered method of control over this process. Injection of leptyne to people who lost weight recently prevented psychological reaction, which stimulates gain of weight. This reaction has no relation to gluttony or lack of will power. It is possible connected with past of human when hunger changed to feast after successful hunting.
