1. What is the Body Fat Percentage Formula?

This formula estimates body fat percentage specifically for men, taking into account waist and neck circumference along with height. It's particularly useful for individuals with significant muscle mass as it accounts for body proportions.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \text{waist} \) — Waist circumference at navel (cm)
• \( \text{neck} \) — Neck circumference (cm)
• \( \text{height} \) — Height (cm)
• \( \log \) — Logarithm base 10

Explanation: The equation accounts for the relationship between body measurements and fat distribution, with height helping to normalize for body size.

3. Importance of Body Fat Calculation

Details: Body fat percentage is a more accurate indicator of fitness than BMI alone, especially for muscular individuals. It helps assess health risks and track fitness progress.

4. Using the Calculator

Tips: Measure waist at navel level and neck just below the larynx. All measurements should be in centimeters. Ensure waist measurement is greater than neck measurement.
