171 height standard weight male

People all have standards for height and weight. If there is a big difference between your height and weight, you should pay attention to adjusting your physical condition. However, most standards are just reference values ​​and cannot be generalized. As long as there are no other obvious abnormal reactions in your body, you don't need to be too nervous. You can just do some physical exercises to make your body proportions look the best.

The BMI value 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 a BMI value, and then find out whether there is a linear correlation between the value and the incidence rate. However, with the advancement of technology, the BMI value is now only a reference value. To truly measure whether a patient is obese, body fat percentage is more accurate than BMI, and waist-to-height ratio is better than body fat percentage, but 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 method to measure obesity).

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

The concept of height-weight index was first proposed by the Belgian polymath Kettler in the mid-19th century. Its definition is as follows:

Body Mass Index (BMI) = Weight (kg) ÷ Height^2 (m)

EX: 70kg÷(1.75×1.75)=22.86

For example:

For example, a person is 1.75 meters tall and weighs 68 kilograms. His BMI = 68/(1.75^2) = 22.2 (kg/m^2). A BMI index of 18.5 to 23.9 is normal.

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

It is more accurate than simply using weight to measure the risks of heart disease, high blood pressure, etc. caused by being overweight.
