Body Mass Index (BMI) takes only two anthropometrical measures into account: height and weight. Based on the calculated BMI, health officials categorize associated health risks based on the following:
| BMI |
Classification |
| <18.5 |
Underweight |
| 18.5 - 24.9 |
Normal (healthy) |
| 25 - 29.9 |
Overweight |
| 30 or higher |
Obese |
One thing the BMI fails to consider is lean body mass. It is very possible for a healthy, muscular individual with very low body fat to be considered obese. For this reason, BMI seems to be more reliable for non-athletes.
Calculating BMI:
BMI = (weight in pounds divided by height in inches squared) multiplied by 705
| BMI = |
