Question 1

How accurate is the body fat calculator?

Accepted Answer

Our calculator uses the US Navy Method, which is a widely accepted formula for estimating body fat percentage. While not as accurate as DEXA scans or hydrostatic weighing, it provides a good estimate with a margin of error of about 3-4%.

Question 2

How do I measure my body parts correctly?

Accepted Answer

For neck: measure around the narrowest part below the Adam's apple. For waist: measure at the navel level while breathing normally. For hips (women): measure around the widest part of your buttocks. Use a flexible measuring tape and keep it snug but not tight.

Question 3

What is a healthy body fat percentage?

Accepted Answer

Healthy body fat ranges vary by gender. For men: 6-13% is athlete range, 14-17% is fitness, 18-24% is average. For women: 14-20% is athlete range, 21-24% is fitness, 25-31% is average. Essential fat is 2-6% for men and 10-14% for women.

Question 4

Why do I need to measure my hip (for women)?

Accepted Answer

The US Navy Method uses hip circumference for women because it provides a more accurate calculation of body fat. Men don't need hip measurements as the formula uses different calculations based on body composition differences.
