BMI is the abbreviation of Body Mass Index. BMI Chinese means “Body Mass Index” and is calculated based on your height and weight. BMI is recognized worldwide as a grading method for assessing the degree of obesity. Currently, the World Health Organization (WHO) also defines obesity or overweight by BMI.
The BMI is calculated by dividing the kilogram of body weight by the square of height (in meters).
The formula is: body mass index (BMI) = weight (kg) / height square (m * m)
For example: a person is 1.75 meters tall and weighs 68 kilograms. His BMI = 68 / (1.75 × 1.75) = 22.2 (kg / m * m)
It is normal when the BMI index is 18.5 to 24.9. BMI is a closely related indicator of total body fat, which takes into account both weight and height. BMI is simple, practical, and can reflect systemic overweight and obesity. When measuring the risk of heart disease and high blood pressure due to overweight, it is more accurate than simple weight.
However, it should be noted that not everyone applies BMI, such as:
1. under 18 years of age;
2. Being an athlete;
3. Doing weight training;
4. pregnant or breastfeeding;
5. An old man who is weak or sedentary.
