Extended data:
At the age of 20 ~ 25, people's physiological functions reach the peak of their lives. After a short period of stability, the functions of human organs and systems began to decline slowly from the age of 30, with an annual decline of about 1%. So with the increase of age, the prevalence rate is gradually higher than that of young people. Take hypertension as an example, the incidence rate is eight times that of young people.
In the cardiovascular system, from the age of 30, the cardiac blood transfusion decreased by 6-8% every 10 year, while the blood pressure increased by 5-6% in the same period. The elasticity of vascular wall is reduced due to the gradual hardening of arteries, and the vascular motor function and blood pressure regulation ability are weakened. The concentration of cholesterol in blood also increases with age, which can lead to atherosclerosis of coronary artery and cerebral artery.
When the lesion becomes more serious, the arterial lumen narrows, resulting in insufficient blood supply to the heart or brain or even ischemia, resulting in cardiovascular and cerebrovascular diseases such as chronic myocardial hypoxia, angina pectoris, myocardial infarction, sudden death, cerebral hemorrhage, cerebral thrombosis and encephalomalacia. These diseases are the biggest threat to the health and life of middle-aged people.
Middle-aged people are the backbone of society, shouldering the responsibilities of the state and society, and are the main force of various departments and industries. They have heavy tasks, great responsibilities, high expectations for career achievements, diligence and responsibility, and long-term high-intensity mental pressure. This situation seriously threatens the physical and mental health of middle-aged people, especially middle-aged intellectuals.
Middle-aged people not only have a heavy workload, but also have a family burden. Career success or failure, position change, personnel change, family status, birth and death, weddings and funerals will all cause psychological waves and require them to adapt and cope.
When people reach middle age, most people will gradually become obese. There are many reasons, such as insufficient labor force, poor metabolism, overeating, overnutrition and subcutaneous fat accumulation. Obesity can be roughly divided into three types: thick waist, big belly and loose abdomen.

The diet of three meals a day should be arranged reasonably. Eat less indigestible meat, poultry and eggs. Even if you want to eat, you should eat in Chinese. If you eat them at dinner, you will get fat easily. Dinner is mainly vegetables and fruits, and it stops at eight. Don't rush to sleep after dinner. There should be at least 3 hours between dinner and going to bed. Remember: don't eat midnight snack just because you are greedy.

Because there are too many nutrients and too few calories, the "import and export" is not balanced, which leads to too many nutrients accumulating in the abdomen and making it "suddenly pop out".
The key to make the "big belly" slim is to change the diet structure on weekdays and generally grasp the principle of "less meat and more vegetables, and eat as little as possible". It is best to stop eating once a week. In order to prevent the stomach from being "wronged" when stopping eating, you can eat a small amount of fruit.
A person with a loose abdomen.
The main reason is drinking too much water. Excessive water will increase the burden on the kidneys and bladder, leading to relaxation of the lower abdomen. In order to suit the remedy to the case, we should strictly control the daily drinking water. Drink a small amount of water at a time and avoid "swigging".
