BMI stands for Body Mass Index which is a measure of an individual’s weight relative to their height. The measurement is based on the formula :
- BMI = (( Weight in Pounds) / ( Height in inches ) x ( Height in inches ) ) x 703
or
- BMI = ((Weight in Kilograms)/(Height in Meters) x (Height in Meters))
Studies have found correlation between Body Mass Index and certain health risks. BMI is a general measure of an individual’s total body fat. However, it may overestimate an individual’s total fat and may also underestimate one’s total body fat. Certain BMI scores are associated with health categories:
- Underweight: Below 18.5
- Normal: 18.5-24.9
- Overweight: 25.0-29.9
- Obese: 30.0 +
Although BMI is a very popular measurement, too many variables are not taken into account that make the reading unreliable. For instance, an athlete may be 5 foot 10, 180 pounds, and possess very little body fat. According to the formula, this particular athlete’s BMI would read 26.5. This would classify the individual as overweight! This athlete has above average muscle mass which leads to the overestimation. Many trainers and doctors agree that simply performing a body fat test is far more effective than a BMI measurement in getting an idea of one’s health. However, many people still like to know their BMI so that’s why we provided the formula.
