What is the Body Adiposity Index (BAI)?

The **Body Adiposity Index (BAI)** is an alternative method of measuring human body fat percentage. Unlike BMI, which calculates weight relative to height, BAI correlates hip circumference to height. The calculation does not rely on total weight, making it highly useful in places where scales are unavailable or unreliable.

Formula used: BAI = (Hip circumference in cm / (Height in meters ^ 1.5)) - 18.

Frequently Asked Questions

BAI is often a better predictor of body fat percentage than BMI for certain populations, but it can overestimate fat percentages for extremely muscular athletes.

You only need your height in centimeters and your hip circumference measured around the widest part of the buttocks.
