The correct name for bmi is BMI. the normal standard for BMI is 18.5 to 24.9 kg/m². BMI refers to body mass index, which is used to measure the degree of physical obesity in adults. The formula is BMI (kg/m²) = weight (kg) / [height (m)]².BMI 18.5～24.9kg/m² is normal, <18.5kg/m2 is thin, more than 25kg/m2 is overweight, more than 30kg/m2 is obese. However, BMI cannot accurately describe the distribution of body fat and cannot distinguish between fat and muscle content, and muscular people are often easily misjudged as obese. For people with high BMI value, they should carry out scientific weight reduction in time, exercise properly and eat reasonably, so as to reduce the BMI value to the normal range. People with high BMI value can go to the nutrition department of regular hospitals for consultation, and carry out standardized weight reduction with the help of nutrition doctors.
