Why Use BMI? BMI is not a perfect measure, because it does not directly assess body fat. Muscle and bone are denser than fat, so an athlete or muscular person may have a high BMI, yet not have too much fat. But most people are not athletes, and for most people, BMI is a very good gauge of their level of body fat. Research has shown that BMI is strongly correlated with the gold-standard methods for measuring body fat.

BMI Indications of Clinical Malnutrition Body Mass Index. Body mass index (BMI) can determine whether a person has an appropriate weight for his or her height by comparing the proportions between the two measurements. In mathematical terms, body mass equals 703 times the quotient of a person’s body weight divided by the square of his or her height.eople who are underweight have a BMI of 18.5 or lower. When a person has what is considered to be an underweight BMI, clinicians will gather other data and, together with BMI, determine whether there should be concerns regarding malnutrition.
