The standard weight of 176cm male should be 71kg, the calculation formula is (height – 105) kg, that is, 176-105 = 71kg, this is a simple algorithm. You can also calculate the standard weight according to the World Health Organization’s calculation method, using (height cm – 80) × 70% for calculation, that is, (176-80) × 70% = 67.2kg. In addition, ± 10% of the standard weight is the normal weight, for 176cm male, as long as the weight range is 60.48-73.92kg, it is normal. Below or above this value, weight abnormalities are considered. If the weight of 176cm male is lower than 60.48kg, it is considered that there is a thin condition, so it is necessary to adjust the diet structure, adequate rest and avoid irregular eating and other bad habits to promote weight gain. If the weight of 176cm male is higher than 73.92kg, it is considered that there is an overweight condition, so it is necessary to exercise moderately and reduce the intake of high-calorie and high-fat food to reduce weight. In addition, if the weight abnormality is caused by a disease, the original disease needs to be clarified, and then targeted treatment will be carried out to alleviate the weight abnormality. However, for people with high muscle content, such as athletes and bodybuilders, the values derived from the above formula are not more accurate results, because more muscle and less fat, the weight will be heavier than the average person with the same height. In addition, for younger children, old and frail senior people are not applicable, need to make a comprehensive judgment according to the specific situation.
