Understanding BAI
The Body Adiposity Index (BAI) is a method of estimating body fat percentage based on hip circumference and height. It was developed as an alternative to BMI that doesn’t require weight measurement.

BAI Formula
BAI = (Hip Circumference / (Height^(1.5))) – 18
Where hip circumference and height are in the same units (cm or inches).

BAI vs BMI: Key Differences
BAI estimates body fat percentage directly from hip circumference and height, while BMI uses weight and height. BAI may be more accurate for individuals with high muscle mass.
