171 standard height and weight male

People all have height and weight standards. If they are too different from this standard, people should pay attention to adjusting their physical condition. However, most standards are only reference values ​​and cannot be generalized. As long as there are no other obvious abnormal reactions in the body, there is no need to be too nervous. You can only do some physical exercises. This is to make your body proportions appear in the best state.

BMI was originally designed as a statistical tool for public health research. When we need to know whether obesity is the cause of a certain disease, we can convert the patient's height and weight into BMI values, and then find out whether there is a linear relationship between the values ​​and the incidence rate. However, with the advancement of technology, the current BMI value is only a reference value. To truly measure whether a patient is obese, body fat percentage is more accurate than BMI, and the waist-to-height ratio is better than body fat percentage. However, the best view is to look at visceral fat (if visceral fat is normal, even if the waist circumference is large and the body fat percentage is high, the health risk is not high. Many Japanese sumo wrestlers use this fat method).

Therefore, the role of BMI has gradually changed, from a medical purpose to a slimming indicator for the general public. BMI is the abbreviation of BodyMassIndex. BMI in Chinese means "body mass index" and is calculated based on your height and weight. BMI is a world-recognized grading method for assessing obesity. The World Health Organization (WHO) also uses BMI to define obesity or overweight.

The concept of height and body mass index was first proposed by the Belgian generalist Ketler in the mid-19th century. It is defined as follows:

Body mass index (BMI) = weight (kg) ÷ height^2 (m)

EX：70kg÷（1.75×1.75）=22.86

Example:

For example: a person's height is 1.75 meters and his weight is 68 kilograms. His BMI=68/(1.75^2)=22.2 (kg/m^2). When the BMI index is 18.5~23.9, it is normal.

BMI is an indicator closely related to the total amount of body fat, which takes into account two factors: weight and height. BMI is simple, practical and can reflect systemic overweight and obesity.

When measuring the risk of heart disease, high blood pressure, etc. due to being overweight, it is more accurate than simply judging by weight.
