The reasons for excess weight

So, as you probably know, the main cause of obesity is excessive intake of food and insufficient exercise. Although obesity can develop from other internal causes. For example, due to dysfunction of the hypothalamus - a small but very important part of the brain, decreased secretion of thyroid gland and pancreas, the adrenal glands. Investigate the nature of people's diet and excess weight showed that they had used dietary proteins, fats and carbohydrates in the 1.5 - 2 times more than the norm. Nutrition obese people, typically characterized by higher consumption of bakery products, sugar, potatoes and others found that the more overweight a person is, the more he gives preference to sweet and fatty foods. To bad habits leading to obesity, can be attributed the abuse of salty foods, spices, alcohol. Occasional meals also lead to increased body weight. This is especially true for people, full-bodied. It should be noted that about 40 - 50% of overweight people more or less burdened with hereditary predisposition to completeness. The study of this question showed that if one parent has obesity, the number of obese children in these families is 40% if both parents to this disease, their children 80% of cases, too, are obese. Contribute to weight Sundays and public feasts and banquets, where a large variety of dishes with a predominance of acute snacks, salty foods, baked goods. In the daily diet of people began to dominate the refined products, the share of animal products and, primarily, animal fats, confectionery and bakery products, with relatively insufficient consumption of vegetable oils and vegetables. Important role in obesity is a sedentary lifestyle. With this way of life even under the rational nutrition consumption is lower than the caloric value of food intake. Average rates of physiological requirements include mandatory energy consumption per physical work at least 600 kcal. In fact, in a sedentary work costs often make up a total of 200 - 300 kcal. Characteristic difference in the activity of obese and normal individuals. Typically, obese choose to work, requiring less energy expenditure. Sedentary work leads to further weight gain, which itself is already beginning to contribute to limited mobility. Thus, a person gets into a vicious circle: inactivity, laziness contribute to obesity, and obesity - laziness (immobility). Consequently, people with high fatness or obese enough to be more physically active, because inactivity contributes to the development and maintenance of obesity. Some to justify their passivity refer to the fact that physical activity increases the appetite and therefore does nothing for weight loss. But this is misleading. Yes, exercise increases the appetite, but it is a natural physiological mechanism by which the body compensates for your energy costs. If you're a passive lifestyle, it does not mean that you have a weakened appetite, he remains at least at the same level as that at low energorastratah your body leads to an increase in your weight. In humans, there is an automatic regulation of the amount of energy derived from food and its consumption. Appetite is a kind of regulator of this balance. If it affects the same points of saturation, which are located in the hypothalamus of the brain, this mechanism is disturbed, the amount of food consumed increases, which contributes to obesity. As you can see, the formation of fat figures associated with dysfunction of the alimentary center, with an increase in its excitability. With overeating stomach, sending nerve impulses in subcortical centers of the brain, increases appetite, helping to perpetuate habits plenty to eat. People who love to eat, besides not engaged in physical work, nutrients are not lost are not oxidized in the body to the finished product, and transformed into an inert tissue that requires constant feeding and oxygen. In connection with this image as it is another vicious circle: people can not overcome the feeling of hunger - eat a lot, and this, in turn, contributes to the completeness, because to save the life of the fat cells need more and more nutritional resources. Much of the development of obesity depends on the profession and way of life. The cook, for example, obesity occurs in 40 - 50% of cases, the frequency of obesity increased in proportion to length of service. Women are obese than men. The main predisposing factors to the fullness of them are pregnancy, childbirth, breast-feeding. Both women and men have the highest percentage of obesity in the age of 40 - 50 years and older, ie for that period of life when it's hormonal changes in the body decreases energy expenditure, decreased metabolism. Observed that obesity usually develops in people who have suffered them in childhood. Unfortunately, gradually builds fullness is often overlooked, and to the same person during this period is often referred to as it looks good. But this is precisely the moment when overlooked preventive measures. Man begins to worry when obesity has reached a significant degree. Therefore often recommended to consider the figure in the mirror and regularly weighed. Below is a table to match the weight, height, age and gender. Tab.
