There seems to be an unavoidable topic in middle age - 'middle-aged obesity'. Why is it so easy to gain weight after entering middle age? Many people point the culprit towards "metabolism", believing that it is caused by slow energy metabolism and reduced consumption in the body. So, is there a relationship between "gaining weight" and "metabolism"? Is metabolism responsible? There is indeed a "metabolic" responsibility for gaining weight. Let's take a look at a statement that seems very reasonable. After reaching middle age, the organs of the body will enter a relatively slow period, and energy metabolism seems to be the same. The older the person is, the lower the basal metabolic rate. Therefore, when entering middle age, they cannot consume and absorb the corresponding energy, which is accumulated in the body and converted into fat. However, a 2021 article published in the top journal Science overturned this traditional understanding by studying the changes in human metabolism throughout the entire life cycle. Research has found that from the age of 20-60, which is a long period of young adulthood to the high incidence stage of middle-aged obesity, energy expenditure remains stable, and after the age of 60, the overall energy expenditure level of the elderly begins to decline. So it seems that we are wrong about 'metabolism'. Is it really wrong to blame "metabolism"? Let's take a look at a study from Sweden that found that lipid turnover rate decreases with age. Lipid turnover refers to the ability of adipocytes to store and remove lipids. If the lipid turnover rate decreases, triglycerides will be stored in large quantities, leading to an increase in fat volume and weight gain. In this way, "gaining weight" and "metabolism" are related, but this metabolism is not that metabolism. Is the "root cause" of the disease here, and "middle-aged obesity", a metabolic error? Does this pot need to be metabolized? You need to memorize it, but not all of it. Research has shown that people aged 30 and older are 20% less active than those aged 20. Therefore, it seems that less exercise may be the main reason for "middle-aged obesity". In addition, stress, emotions, staying up late, insomnia, overeating, and other "fattening agents" all make "middle-aged weight gain" more common. From the perspective of traditional Chinese medicine, the body of middle-aged people has undergone changes compared to young people, and their bodies have begun to weaken. The Yellow Emperor's Internal Classic records that in the fifth and seventh dynasties, the Yang Ming meridian declined, and the face began to scorch, and the hair began to fall. In the sixth and seventh dynasties, the three Yang meridians declined, and the face became scorched, and the hair began to turn white. On May 8th, men experience kidney qi failure, hair loss, and teeth withering. On June 8th, their yang qi is depleted, and their faces are scorched. What is being discussed here is that from the age of 35 for women and 40 for men, Qi and blood gradually weaken and hair begins to fall off. To reverse growth, it is necessary to do these things well. It can be seen that "middle-aged obesity" has a complex relationship with metabolism and is also related to self changes. So, how to slow down the speed of aging and "middle-aged obesity"? Qi Bo, a famous medical expert in ancient China, said: In ancient times, people who knew about it were based on yin and yang, harmony with martial arts, moderation in food and drink, regularity in daily life, and not excessive labor. Therefore, they were able to form themselves in harmony with the gods, and end their days and years, passing away at the age of a hundred. Today's people are not like this. They use wine as their plasma, recklessness as their routine, drunkenness as their room, desire to exhaust their essence, and dissipation of their true essence. They do not know how to hold it to full, and from time to time, they should control the gods. They must be quick in their hearts, go against life and happiness, and live without restraint, so they will decline after half a century. So, I want to reduce
