Check Your BAI instead of BMI

May 25, 2011
If you are used to control your weight, then you are most probably familiar with Body Mass Index (BMI) , a basic tool to evaluate your weight based on your height. BMI shows whether you are overweight, underweight or have normal weight. BMI above 25 is a warning sign of obesity. Now scientists offer a new type of measurement called BAI (body adiposity index) , which is more accurate than common BMI evaluation.

BAI is a ration of height and hip width, which will give you more accurate information about your weight. Why is BAI better than BMI? Specialists at the University of Southern California in Los Angeles say that BMI may not be suitable for certain body types. For example, if you have athletic body, your BMI may give you the same number, as if you were somewhat overweight. BAI is more accurate in determining if the person has unhealthy fat and make a clearer difference between muscle mass and fat mass.

So how is the BAI actually determined? According to the researchers, the formula of BAI is:
BAI=(hip/height x the square root of height) minus 18.

This may seem a bit too complicated for regular check ups, so you can calculate your BAI online.

The hip circumference is measured at the widest point of the buttocks. The BAI from 21 to 33 percent means that you have healthy body fat, while the number that is above 33 percent indicates that you are overweight.
