What are the body mass parameters What is body weight

Physics concepts.

Definition: A center of mass can be used.

centroid) to represent an abstract body of matter.

Explanation: A mass body has only one centroid. A mass can be an object or a combination of complex silver-numbered objects.

For example, the Earth is a mass, and if the Earth and the Moon are combined, they are also a mass, because they have only one common centroid. A mass can be a virtual mass particle, such as atoms and electrons. Mass bodies not only have a fixed form, but also can have no fixed form, such as gases, etc.

As long as it is a material body that can be represented by a centroid, regardless of size, structure, or form, it is a mass body.

BMI index, referred to as body mass index, is a standard commonly used in the world to measure the degree of obesity and thinness of the human body and whether it is healthy.

The formula is: BMI = weight and height squared. (Weight unit: kg; Height unit: meters. ）

BMI is a common indicator to measure the degree of fat and thinness of the human body and whether it is healthy in the world, the normal value of BMI is between 20 and 25, more than 25 is overweight, and more than 30 is obese.

Based on anonymized data of 3.6 million people, Ba et al. analyzed the relationship between changes in body mass index and deaths due to multiple factors.

The results showed that people with BMIs of 30 or above had an increased risk of dying from cancer, heart disease, respiratory disease, kidney disease and diabetes. In general, life expectancy decreases for males and for females. But a low BMI is also associated with an increased risk of death from a wide range of diseases, including cardiovascular disease, respiratory disease and dementia.

This shows that a low BMI is also an important indicator of unhealthy health.

The above content reference: People's Health Network - BMI value is not the higher the better! Too high or too low increases the risk of death.

The body mass index is obtained by dividing the number of kilograms of body weight by the square of the number of meters of height.

For example, if a person is tall in meters and weighs 68 kg, his BMI = 68 (kg m2). When the BMI index is normal.

Do you know BMI and what weight range can you live longer?

First, multiply the height by the height, which is equal to the square meter of the body, and the kilogram with the weight is equal to the body index

Body mass index (BMI), also known as body mass index, is calculated by dividing weight (kg) by height (m) squared, and a body mass index of more than 30 is considered obese. For example, if someone is meters tall and weighs 65 kilograms, then his body mass index is 65 (

Evaluation Criteria: Malnutrition; bmi＜15

thin; bmi＜

Normal; Overweight; 25＜bmi＜30

Corpulent; 30＜bmi＜40

Body mass index (body mass index) = weight (kg) Height (m) squared.
