Hormones produced by the female body ( estrogens - estradiol, estriol , and others). also have an effect on fat metabolism and distribution of body fat. The average ratio of fats and proteins in the body young adults - 15 to 45%, and the girl in the body - 25 to 20%. For the beginning of menstruation requires a so-called critical mass of the body (not less than 50 kg) and a certain percentage (not less than 35), fat mass of the total weight of the body. Female body accumulates fat to store up energy to feed their children and to ensure supply to the case during pregnancy, will miss a meal.
Despite the fact that the living conditions of modern humans have changed a lot compared to those in which our ancestors lived, nature continues to operate, "the old fashioned way." Most of the girls who have fat deposited on the stomach and thighs are too intense, try to get rid of this "gift" of nature through a variety of diets. However, the "guilty" of this process, estrogens, often reduce all efforts to naught. In fairness it should be noted that estrogensexert a positive influence, and on the exterior - provides elasticity and silkiness of the skin, breast growth, and many other factors determining female attractiveness.
The rate for women ( estradiol ):
- In the follicular phase menstrualnogotsikla - 20,7-85,8 pg / ml;
- In preovulyatsii - 82.8 - 287.3 u / ml;
- In the luteal phase - 37,9-172,4 pg / ml;
- In postmenopausal 0,68-54 ng / ml. The rate for children: 1,6-9,1 ng / ml.
Another hormone, testosterone , is secreted in the male and the female body, but in men it produces 15-20 times more.
After 35-40 years of testosterone and estrogen is reduced, so that the fat in both men and women begins to be deposited in the abdominal area.
And finally, there is a hormone produced in the stomach - ghrelin. According to recent research scientists, this hormone into the brain sends signals of hunger that many people leads to overeating
