Most people find themselves more or less "fat" after middle age. In fact, there is a close relationship between age and obesity. According to domestic surveys and statistics, after middle age, the obesity rate is significantly higher than other age groups. It is not difficult to see from the picture on the next page that obese people begin to gain weight at the age of 30-39, followed by 40-49. So why is there such a proportional relationship between age and obesity? (1) physiological changes. After people reach the age of 30, the functions of various parts of the body begin to decline gradually. For example, if the working ability of the heart drops 1% every year, the chest will gradually harden, the air intake will decrease accordingly, and the transmission speed of nerves will slow down. Similarly, the body's various metabolic levels are also declining year by year. After middle age, people's physical and mental consumption decreases, and the corresponding dietary intake does not decrease much, but the metabolic level decreases, so the intake of calories can not be fully utilized in time, but is converted into fat to accumulate in the body. In addition, after middle age, the distribution of fat in the body will also change, from uniform distribution throughout the body to concentrated transfer to the abdomen, buttocks and thighs, so it is easy to show obesity. (2) Changes in body consumption. After people enter middle age, the consumption of both physical and mental activities is greatly reduced. With the decrease of physical activities such as physical exercise and social activities, excess calories are bound to be converted into fat. (3) mental changes. The utilization of heat is regulated by endocrine system. The endocrine system is controlled by the nervous system, which is related to mental factors. As the saying goes, "the heart is wide and the body is fat" is the truth. After middle age, the pressure from work and family is greatly reduced, and many people have mastered work skills at work, so promotion is not a problem. Even if they don't achieve outstanding results, most people will enjoy it and meet a stable job and a familiar job. I spent a difficult marriage and childbearing period at home. Psychologically relaxed and comfortable life is also one of the reasons for obesity. Although people have the above factors that are conducive to getting fat after middle age, it does not mean that all people will get fat after middle age. As long as you pay attention to adjusting your diet and insist on proper physical exercise. You can still maintain a strong posture.
