are three groups of factors:
- Problems in a hypothalamus
It is the site of a brain which controls thirst, hunger, a metabolism, a dream, body temperature and emotional activity. In a hypothalamus there is a center of control of food behavior. If its work is broken, at the person the appetite increases and can not arise sense of fulness. It consumes many calories and does not spend them. As a result, excess weight appears. Injuries, infections and benign tumors can break work of a hypothalamus.
- Endocrine problems
A set of weight is caused by violations in work of endocrine glands. The reason of completeness can become:
- A hypothyroidism or the lowered function of a thyroid gland. It produces hormone thyroxine which provides a normal metabolism. In case of a hypothyroidism the metabolism is broken, the expense of calories slows down. The person can eat and gain weight a little.
- Gipogonadizm at men or the lowered function of gonads. As a result of deficiency of sex hormones the boy or the man gets fat in a women's way – in the bottom of a stomach and in hips.
- Giperkortitsizm or the increased production of hormones of bark of adrenal glands. Fat is laid generally in a neck, the person, a stomach and a breast.
In all these cases fat is a harbinger of more serious changes. Therefore surely it is necessary to address the endocrinologist. Without it it will not turn out to lose weight.
- Overeating
In 95% of cases the overeating provokes excess weight. If more energy comes to an organism, than it is spent, it turns into fat.
Most of people think that overeating is the use of a huge amount of food. But actually it not so. You can eat as all and to get fat. Because you move less, than others.
The person overeats also during a stress. Also overeating can be caused by problems with sense of smell when food seems tasteless. Then the person eats more, than usually.
Most often overeat in the company, behind viewing the movie, on the run or at the computer.
