The formula is (height-105)kg, that is,176-105 = 71kg, which is a simple algorithm. You can also calculate the standard weight according to the calculation method of the World Health Organization, and use (height cm-80)×70% to calculate, that is, (176-80) × 70% = 67.2kg ... In addition, 10% of the standard weight is the normal weight. For boys with 176cm, it is normal as long as their weight ranges from 60.48-73.92kg to 73.92 kg. Below or above this value, the weight is considered abnormal. If 176cm male students weigh less than 60.48kg, they are considered to be thin. At this time, we should adjust our diet structure, have enough rest, avoid bad habits such as irregular diet and promote weight gain. If 176cm male students weigh more than 73.92kg, they are considered overweight. At this time, moderate exercise is needed to reduce the intake of high-calorie and high-fat foods in order to achieve the purpose of losing weight. In addition, if the abnormal weight is caused by disease, it is necessary to make clear the primary disease, and then carry out targeted treatment to alleviate the abnormal weight. But for people with high muscle content, such as athletes and bodybuilders, the numerical value obtained by the above formula is not an accurate result, because there are more muscles and less fat content, and their weight will be heavier than that of ordinary people with the same height. In addition, it is not suitable for younger children and the elderly with weak physique, and it needs to be judged comprehensively according to specific conditions.

At present, the commonly used international standard for measuring obesity and health is body mass index. When it is necessary to compare and analyze a person's weight, the health impact on people of different heights is that the body mass index is a neutral and reliable indicator. Body mass index is equal to kilogram weight divided by the square of height. If the adult's body mass index is lower than 18, it is underweight, and the normal range is between 18-24. 24-28 is overweight, above 28 is obese, and the ideal body mass index is 22. In addition, abdominal circumference is also a standard to measure abdominal obesity. If a man's waist circumference is greater than 85, he is obese.
