Understanding the Limitations of the BMI Measure
The BMI calculator is a great tool for assessing health. The most notable limitation is that BMI does not assess distinctions in muscle, fat, or bone mass. An athlete with muscle mass can receive a BMI that is in the "overweight" or "obese" category. He will have excellent physical health and have a very low body fat percentage.
Physical size is another consideration that BMI does not distinguish. If two people have the same BMI, their body composition may still differ. BMI measurement is less reliable for bodybuilders, seniors, and pregnant women.
BMI estimation does not account for the location of the body fat. A large waist circumference is risky than fat distributed around the thighs and hips.
BMI can provide a general sign of whether your weight is within a healthy range. Combine your BMI estimation with an assessment of body fat percentage. You should check the waist-to-hip ratio to complete a comprehensive health assessment picture.
