1. What is the Body Fat Percentage Equation for Men?

The Body Fat Percentage Equation for Men estimates body fat using abdomen and neck circumferences along with height. It provides a simple way to assess body composition without specialized equipment.

2. How Does the Calculator Work?

The calculator uses the following equation:

\[ BF\% = 86.010 \times \log_{10}(abdomen - neck) - 70.041 \times \log_{10}(height) + 36.76 \]

Where:

\( abdomen \) — Abdomen circumference at navel (inches)
\( neck \) — Neck circumference (inches)
\( height \) — Height (inches)

Explanation: The equation accounts for the relationship between body measurements and fat distribution in men.

3. Importance of Body Fat Percentage

Details: Body fat percentage is a key indicator of health and fitness. It provides more accurate information than BMI alone, helping assess health risks and fitness progress.
