1. What is the Body Roundness Index?

The Body Roundness Index (BRI) is a geometric shape measure that estimates body fat percentage based on waist circumference and height. It provides an alternative to BMI that better accounts for body shape and fat distribution.

2. How Does the Calculator Work?

The calculator uses the BRI equation for women:

\[ BRI = 364.2 - 365.5 \times \sqrt{1 - \left(\frac{WC}{2 \times \pi \times H}\right)^2} \]

Where:

\( WC \) — Waist circumference (cm)
\( H \) — Height (m)
\( \pi \) — Pi (approximately 3.1416)

Explanation: The equation models the body as an ellipse and calculates deviation from perfect roundness.

3. Importance of BRI Calculation

Details: BRI correlates with visceral fat and metabolic risk factors. It may provide better health risk prediction than BMI alone, especially for women.

4. Using the Calculator

Tips: Measure waist circumference at the midpoint between the lower rib and the top of the hip bone. Enter height in meters (1 m = 100 cm).

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BRI score?
A: Generally, scores under 3 are considered healthy, 3-6 indicates moderate risk, and above 6 indicates high risk.

Q2: Why is BRI different for women?
A: Women typically have different fat distribution patterns than men, requiring gender-specific calculations.

Q3: How does BRI compare to BMI?
A: BRI accounts for waist circumference and may better identify individuals with normal BMI but high abdominal fat.

Q4: When should I measure my waist circumference?
A: Measure in the morning before eating, at the end of a normal breath.

Q5: Are there limitations to BRI?
A: BRI may be less accurate for very tall or short individuals and those with unusual body shapes.
