After 60 years old, this weight is healthy
Core tip: too fat and too thin are not good, may lead to shortened life!
We may have heard such a saying: "it's hard to buy a thousand gold, the elderly are thin". Especially at present, with rich living conditions, more and more people begin to "get fat" in middle age. But is there any scientific basis for this? Is it true that the thinner the elderly, the better?
Too fat is not good, too thin is not good!
It is undeniable that the harm of obesity is considerable. For middle-aged and elderly people, common hypertension, hyperlipidemia, diabetes, coronary heart disease, stroke, cancer, and other diseases have a certain relationship with obesity. In short, the fatter the person, the higher the risk of disease. However, the premise of saying these words is that this person has to be included in the "fat man" list. In the healthy weight range, there was no such correlation.
On the contrary, old people can't be too thin. Medicine believes that when the actual weight is less than 20% of the standard weight, it belongs to emaciation. Some studies have found that the elderly are not conducive to health, especially the elderly who are themselves plagued by chronic diseases, which will lead to aging, deterioration of physical fitness, aggravation of the disease, and more prone to accidents. In real life, many old people are hungry and thin, and the consequence of doing so is to reduce the body's muscle and water, but not much fat. As a result, the ability to exercise will be reduced, the bone health will be damaged, and it is easy to be injured.
After 60 years old, how much weight is healthy?
The elderly over 60 years old, they can't compare with the young people, and the thinner the better. They need to maintain a healthy weight, including muscle and fat.
A person's body mass index (BMI) is generally used to measure a person's weight.
BMI = the square of weight (kg) × height (m). At present, the normal range of BMI is 18.5-23.9.
Some studies have found that the life expectancy of obese men and women with BMI higher than 24 is shortened by 4.2 and 3.5 years respectively, while that of overweight men and women with BMI lower than 18.5 is shortened by 4.3 and 4.5 years.
Other studies have found that when the BMI of the elderly is lower than 15, it belongs to sarcopenia of the elderly, and the mortality will increase by 2.8 times. BMI higher than 24, belong to obesity, mortality will increase by 49%.
All studies have confirmed that being too fat or too thin is not good, which may lead to a shorter life span!
For young and middle-aged people under 60, BMI should be kept between 18.5-23.9, which is the healthiest;
For people over 60 years old, BMI should be kept between 20.9 and 24, to minimize the risk of death due to diseases.
For example, a 62-year-old man, with a height of 1.78m and a weight of 71kg, has a BMI of 71 △ 1.782 = 22.4, which is the normal value between 20.9 and 24. Even if he has a healthy weight, as long as he has good nutrition and healthy life at ordinary times, and can actively treat diseases, he is likely to live a long life.
In addition to BMI, there is another index to measure weight, that is waist circumference, because the size of waist circumference is the standard to judge whether it is abdominal obesity, and the harm of abdominal obesity is more serious. The study found that for every 5cm increase in waist circumference, the risk of death increased by 17% in men and 13% in women. In China, the waist circumference of male ≥ 85CM and female ≥ 80cm belong to abdominal obesity. Therefore, people with beer belly must pay attention to it. It's time to lose weight!
