BMI Prime: Introduction What is BMI Prime? BMI Prime (abbreviated BMIâ) is an index of total body fat content. It is a simple modification of the familiar Body Mass Index (BMI) system. Back to Contents; How is BMI Prime Defined? BMI Prime is the ratio of a personâs Actual Weight (or Mass) to his Upper Weight (or Mass) Limit. It is also the ratio of a personâs Actual BMI to her Upper Limit BMI.
Individuals with BMI Prime less than 0.74 are underweight; those with between 0.74 and 1.00 have optimal weight; and those at 1.00 or greater are overweight. BMI Prime is useful clinically because it shows by what ratio (e.g. 1.36) or percentage (e.g. 136%, or 36% above) a person deviates from the maximum optimal BMI. For instance, a person with BMI 34 kg/m2 has a BMI Prime of 34/25 = 1.36, and is 36% over their upper mass limit.
