Note: As BMI does not measure body composition in any way - it is effectively a flawed and faulty index. However it is still used by many government health institutions.
Body Mass Index
BMI uses a mathematical formula based on a person's height and weight. BMI equals weight in kilograms divided by height in meters squared (BMI = kg/m2). The BMI table that follows has already calculated this information.
A BMI of 25 to 29.9 indicates a person is overweight. A person with a BMI of 30 or higher is considered obese. The BMI does not measure body fat levels - so you could be rippling with muscle - and BMI will show obese.
Like the weight-to-height table, BMI does not show the difference between excess fat and muscle.
However, take your BMI reading with a grain of salt - or ignore it completely! If a bodybuilder measured their BMI, they would show up as obese. This is obviously not true. It is difficult to apply a "one-size-fits-all" to unique body types. Some ethnic groups also have denser and heavier bone structure which can skew the results even more.
