The link between weight and death has been discovered! This weight is healthier after 60, study finds
Aunt Liu, who retired from the Forestry Bureau, is 66 years old this year. She has always been in good physical condition, but she always feels that she is a little fatter.
A few months ago, Aunt Liu suddenly found that she lost weight, and she was very happy , but after that, she seemed to have lost a lot of weight. Friends who hadn’t seen her for a few months said she was a little out of shape, and urged her to lose weight. She hurried to check.
After the doctor's examination, it was found that Aunt Liu had liver cancer and had already metastasized!
1. It is hard to buy old and thin with money? Weight, death link found
A research team from a university in the United States tracked 4,576 respondents for 73 years and found that being slightly obese in old age is the longest-lived state.
A study published in The Lancet Diabetes and Endocrinology found that being too underweight or overweight can shorten life expectancy by about four years. The analysis found that a healthy body mass index should be between 18.5-25. If you can have a healthy body mass index at the age of 40, and those who are a little higher in the range, the risk of dying from disease will be lower.
2. After the age of 60, how much weight is better?
Many countries use body mass index (BMI) to determine whether you are overweight or not. Body mass index is calculated by dividing your weight by the square of your height. "Dietary Guidelines for Chinese Residents 2022" pointed out: BMI ≥ 28.0 is obese, 24 ≤ BMI ≤ 28.0 is overweight, 18.5 ≤ BMI ≤ 24.0 is normal weight, and BMI < 18.5 is underweight.
For the elderly, the criteria for judging body mass index are somewhat different from those of young people, and a BMI between 20-26.9 is appropriate .
In addition, waist circumference is also an indicator of life expectancy. Women with a waist circumference greater than 80cm and men with a waist circumference greater than 85cm have a higher chance of suffering from chronic diseases. Therefore, for the elderly, it is not possible to blindly regard thinness as beauty.
3. The old man is too thin? When cardiomyopathy comes to the door
With the continuous increase of age, the human skeletal muscle will continue to age. After the age of 40, the quantity and quality of skeletal muscle are constantly decreasing, with an average annual decrease of 8%. The elderly are too thin, and they have to come to the door when they are hypocardiac.
After suffering from sarcopenia , the risk of fractures in the elderly will increase , and it may also increase the risk of high blood pressure, diabetes, cardiovascular disease, etc., and even affect life expectancy.
Usually, in the diet, we should eat more high-quality protein foods, foods rich in vitamin D, seafood, diversified foods , etc., and try our best to ensure a balanced and comprehensive intake of nutrients to avoid malnutrition. In addition, it is necessary to exercise more and more appropriately, choose an exercise that suits your intensity and stick to it.
There is also a certain relationship between weight and death. For the elderly, it is not the thinner the better, but the fatter. The elderly are too thin and have small cardiomyopathy. Once targeted by sarcopenia, the risk of fractures, high blood pressure, etc. will also increase. Usually, you should ensure a comprehensive intake of nutrients in your diet. Don't think that you can't digest it when you are old. You have to eat when you need to eat. In addition, you must exercise more. Choose suitable sports and keep exercising every day.
