INFORMATION ON BODY COMPOSITION

BODY MASS INDEX

Body Mass Index (BMI) is a number calculated from a person's weight and height. BMI is a reliable
indicator of body fatness for people. BMI does not measure body fat directly, but research has shown that
BMI correlates to direct measures of body fat. BMI is used as a screening tool to identify possible weight
problems for adults.
BMI is calculated by using the following formula based on a ratio between your weight and height:
BMI = weight (lb) / height (inches) / height (inches) × 703
Interpreting the BMI Result

Less than 18.5

BODY FAT

Body fat serves a vital role in storing energy and protecting internal organs. We carry two types of fat in
our bodies: 1) essential fat which is stored in small amounts to protect the body and 2) stored fat which is
stocked for energy during physical activity. While too much body fat may be unhealthy, having too little
fat can be just as unhealthy. Also, the distribution of body fat in men and women is different, so the basis
for classifying the body fat percentage is different between the genders.
