Leptin - a hormone mainly responsible for the appetite and feel full. It got its name from the Greek word \”leptos\” - slender. Leptin sends signals to the brain about the adequacy of fat reserves. When its level is reduced, the brain understands it so that people \”dying of hunger\”, it requires new fat stores, and the man begins to be desired urgently to eat chocolate, sausages or chips. In general, the effect of this hormone in the body is very mysterious. When this hormone was injected laboratory mice, their weight decreased. It turned out that the mechanism of action of this hormone is simple and concrete: it causes the splitting of fat and reduces food intake. It would appear - enter it into the body by injection - and obese patients will not. Nothing of the sort! For patients with obesity it is about ten times higher than in lean. Perhaps because the body full of people somehow loses sensitivity to leptin and so it begins to produce at a higher rate in order to somehow overcome this insensitivity. For weight loss decreases and the level of leptin. Leptin also decreases with the lack of sleep. This partly explains the fact that chronically sleep enough (less than seven hours per night), people are prone to obesity. Those who regularly eats fish and seafood, the level of the hormone leptin balance. phentermine without prescription for weight loss can also be very helpful. This is very good, because there is correlation between high leptin and low metabolism and obesity. Cortisol Cortisol, which is also called \”stress hormone\” - a close relative of adrenaline, both produced adrenal glands. This is a corticosteroid hormone produced spontaneously at the time of high stress and forming part of the protective mechanism of Rights. Cortisol affects the metabolism and excess weight in different ways. As part of the built-in biological mechanism of protection, which manifests itself in stress, it triggers some protective processes and stops others. For example, for many people it increases the appetite during stress, that a man had the strength to confront the outside world, and people in psychologically difficult moments begins to \”comforted\” yum-yum. At the same time it lowers metabolic rate - again, not to lose necessary for the salvation of the stress energy. Because somehow affect the production of cortisol, a person can not, can only receive either minimize stress, changing lifestyles and avoiding sources of stress, or you find suitable ways to relax: yoga, dancing, breathing exercises, prayer, meditation, etc. Adrenaline As we have said, a relative of cortisol, epinephrine, however, affects the metabolism differently than cortisol. If cortisol is released in response to the fear, danger or stress, adrenaline is produced in moments of excitement. The difference seems to be small, but it is. For example, if you jump with a parachute for the first time, then most likely you will experience fear, and you increase the level of cortisol. If you are an experienced skydiver, then probably at the time of the jump, you feel not so much fear, how much emotional arousal is accompanied by the release of adrenaline. In contrast to cortisol, adrenaline speeds up metabolism and helps in lipolysis, releasing energy from them. He runs a special mechanism called \”thermogenesis\” - increase in body temperature caused by combustion of energy reserves of the organism. In addition, the adrenaline rush usually suppresses appetite. Unfortunately, the more a man\’s weight, the lower his production of adrenaline. Estrogen Female hormone estrogen is the ovaries and has many functions in the regulation of the menstrual cycle prior to distribution of fat deposits. That estrogen is one of the main reasons that young women\’s fat is stored, usually in the lower part of the body, whereas in women after menopause and men - in the abdomen. It is believed that the lack of estrogen leads to weight gain. The level of hormones in women begins to decrease for 10 years before menopause. Very often it is primarily manifested in the increased love for sweets. With a decrease in estrogen the body begins to look for it in fat cells. Once the fat cells begin to supply the body with estrogen, it begins to store more and more fat. At the same time a woman begins to lose testosterone, resulting in a sharp decrease in muscle mass. Because the muscles responsible for burning fat, the more muscle lost, the more fat is postponed. That is why it is so difficult to lose weight after 35-40 years. It is known that for the production of male and female sex hormones (estrogen and testosterone) needed mineral boron. In the majority of soil boron is contained in very small quantities, and therefore in our food supply it gets low, which leads to low levels of estrogen and testosterone levels in many people. Additional reception boron often helps to balance the production of these hormones. The level of estrogen and testosterone also decreases with stress. Support muscle mass and slow down its loss may be through weight training. Insulin Insulin - a hormone produced by the pancreas that regulates blood sugar (glucose) in the blood and converts excess of sugar in the fat stores. Violation of insulin leads to diabetes type 2. Popularly speaking, it is the result of a long and hard work of the pancreas due to the constant excess intake of sugar and starch. Eat less food in white, so as not to overload the pancreas and not gain weight. Work of the pancreas, which means that a balanced production of hormones, improves under the influence of the minerals chromium and vanadium and vitamin B3 (niacin). Unfortunately, in the western diet of these minerals and vitamins is usually enough. Additional admission of these substances in the form of vitamin-mineral complexes can help in prevention and early treatment of disorders of the pancreas. Ghrelin Ghrelin - a \”short-lived\” a hormone produced in the stomach, which is designed to send signals to the brain of the famine. Recent studies have shown that fructose (a type of sugar, located especially in large quantities in fruit juices, corn syrup and carbonated beverages) stimulates the production of ghrelin, leading to an increase in the total calorie intake. That is, the consumption of foods rich in fructose, leading to increased and more frequent emergence of feelings of hunger and overeating. Fortunately, most people, a healthy diet, know that you first need to remove from your diet just these products. Thyroid hormones These hormones are similar in nature, which are briefly referred to as T1, T2, T3 and T4, are made of thyroid gland. The greatest influence on weight gain has thyroxine, which speeds up metabolism. Lack of development of thyroid hormones, known as reduced thyroid function, leading to the recruitment of excess weight and other unpleasant diseases. However, the increased output of these hormones - hyperthyroidism, causes their disease, and also undesirable, although people who are overweight, it is rare. That is, in this case is important healthy balance. If you suspect you have a thyroid dysfunction, you can do a blood test on the content of these hormones. But although the use of drugs, regulating the activity of the thyroid gland, is widespread, recourse to them should be a last resort and only on medical prescription. For the proper functioning of the thyroid gland needs iodine to it. Receipt of iodine in the diet can ensure that the consumption of iodized salt, iodine supplements, vitamin-mineral complexes, additives containing algae, etc. Recent studies have shown that thyroid work more improved, if iodine is taken in combination with other minerals - selenium. Furthermore, according to other studies, thyroid dysfunction is accompanied by a low level of copper in the blood. The work of the thyroid gland affected by certain foods. For example, people with reduced function, or people who just want to speed up the metabolism, you should avoid soy foods and excessive consumption of peanuts. A useful natural thyroid stimulator is coconut oil, which is often condemned as a source of saturated fat. In addition, the level of thyroid hormones like testosterone and estrogen, decreases under the influence of stress. So, if you are overweight and you want to lose weight or if your body does not respond to diet, you can make a series of laboratory tests on the contents of hormones in your blood. But do not resort to substitution therapy even in case of deficiency of any hubbub. Most cases of hormone deficiency can compensate for changes in lifestyle and diet, intake of mineral, vitamin supplements, as well as fatty acids.
