The Formula Explained

The C.W. Avery Fitness Health Body Fat Calculator uses the following formula to calculate body fat percentage:

Where:

• waist = waist measurement in centimeters
• hip = hip measurement in centimeters (women only)
• neck = neck measurement in centimeters
• height = height in centimeters

This formula is based on the work of Dr. Charles Avery, a renowned expert in body composition analysis. The formula takes into account your gender, height, and key body measurements to provide an accurate estimate of your body fat percentage.

Interpreting Your Results

Understanding your body fat percentage is crucial for assessing your overall health and fitness. Here's how to interpret the results:

• Essential Fat: 2-5% - This is the minimum amount of fat needed for basic bodily functions.
• Athletes: 6-13% - This range is common for athletes and highly fit individuals.
• Fitness: 14-17% - This range is typical for fit, healthy individuals.
• Average: 18-24% - This range is common for the general population.
• Obese: 25% and above - This range indicates a higher risk of health issues.

It's important to note that body fat percentage can vary based on factors such as muscle mass, bone density, and overall body composition. The C.W. Avery Fitness Health Body Fat Calculator provides a general estimate, but for precise measurements, consider using a DEXA scan or other professional assessment tools.

Worked Example

Let's walk through a worked example to see how the calculator works. Suppose we have a 30-year-old woman who is 165 cm tall, with a waist measurement of 75 cm, hip measurement of 95 cm, and neck measurement of 35 cm.

Using the formula for women:

Calculating step by step:

1. Calculate the sum inside the logarithm: 75 + 95 - 35 = 135 cm
2. Calculate the logarithm: log10(135) ≈ 2.1304
3. Calculate the height logarithm: log10(165) ≈ 2.2179
4. Plug the values into the formula: 495 / (1.29579 - 0.35004 × 2.1304 + 0.22100 × 2.2179) - 450
5. Calculate the denominator: 1.29579 - 0.7492 + 0.4901 ≈ 1.0367
6. Divide 495 by the denominator: 495 / 1.0367 ≈ 477.35
7. Subtract 450: 477.35 - 450 ≈ 27.35%

Therefore, the calculated body fat percentage for this individual is approximately 27.35%. This falls in the "Average" range, indicating that she has a moderate amount of body fat.
