In real life, we all generally believe that underweight or overweight is related to various health problems. On the contrary, maintaining a standard weight seems to be the key to a long and healthy life. But recent research shows that for middle-aged and elderly people, in fact, in terms of longevity, slightly fat people seem to be more "cheap" with age.
Do not believe, research says that people who are slightly fat live longer, which is true ~ ~
In 20021year, a study by Ohio State University was published in the Yearbook of Epidemiology. The study started at 1948 with 4576 participants. This study lasted for 73 years. The results show that people who maintain normal weight when they are young have lower mortality when they are old!
In addition, European scientists took 654.38 million+elderly people as the research object, and finally reached the same conclusion: if they are light in weight after entering old age, the mortality rate will increase by 654.38+00%, and when they are overweight, it will increase by 8%. When the body mass index is around 25, the "slightly fat" elderly people live longer.
In the United States, a 40-year longevity survey was conducted on 6 million people. The results show that people who exceed the standard weight 10%~ 15% have the longest life expectancy and the lowest mortality.
In 2022, the team of Shi Xiaoming from China Center for Disease Control and Prevention also explained in Natural Aging that the elderly aged 80 and over in China may be overweight or slightly obese, which is the result of 20 years' research.
The Graduate School of Medicine of Tohoku University in Japan conducted a 12-year follow-up survey on 50,000 people aged 40-79, and also found that people who are slightly overweight live 6-7 years longer than those who are too thin.

What is "chubby"?
In fact, "micro obesity" is a relative concept. In the vernacular, it means that the weight is slightly above the standard weight, but it has not yet reached the level of obesity.
The weight standard can be measured by body mass index (BMI), that is, a BMI of 24.0 ~ 28 is mild obesity. You can also think that the standard weight ×( 1+ 10%) is slightly fat.
Why do chubby people live longer? Why?
Studies have found that when obese people face diseases, fat reserves can provide more energy to survive the diseases. And the mortality rate of some cardiovascular events will be lower. Especially in the elderly, people with mild obesity have higher bone density and lower risk of fracture. Moreover, a moderate amount of adipose tissue in obese people may have a positive effect on immune function and help the elderly to resist various infections.
Another point is that with the growth of age, human metabolism will gradually slow down, especially in the middle-aged and elderly stage, people with mild obesity may have more stable hormone levels and higher basal metabolic rate to maintain the body energy balance.
In short, the above research shows that it is true that a slightly fat body lives longer.
However, before the end of the topic, I still want to talk about my views. I think everyone's body is unique (physical condition is different), so we should do it according to our own situation and on the advice of doctors. Whether it is normal, slightly fat or other, it is not feasible to fluctuate in a short time. ?
In the young stage, as long as you maintain a normal weight. Entering the middle-aged and elderly stage, you can consider a slightly fat body shape. But you can't lose weight suddenly, which may damage immune function and bone. It is also not recommended to gain weight suddenly, which may increase obesity-related diseases or some chronic diseases. Therefore, no matter which way is adopted, the gradual, scientific and reasonable approach is worth promoting ~
