1. What is the Body Fat Percentage Formula?

This calculator uses a popular formula from Reddit to estimate body fat percentage for women based on circumference measurements. It provides a simple way to track body composition changes.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( Waist \) — Waist circumference at narrowest point (inches)
• \( Hip \) — Hip circumference at widest point (inches)
• \( Neck \) — Neck circumference (inches)
• \( Height \) — Height in inches

Explanation: The formula uses logarithmic transformations of body measurements to estimate body fat percentage.

3. Importance of Body Fat Measurement

Details: Body fat percentage is a better indicator of health than weight alone. It helps assess fitness progress, health risks, and appropriate weight ranges.

4. Using the Calculator

Tips: For accurate results, measure:

• Waist at the narrowest point (typically just above the belly button)
• Hips at the widest point
• Neck just below the larynx
• Measure in the morning before eating, with the tape snug but not compressing skin
