Understanding Body Fat Percentage
Body fat percentage is the total mass of fat divided by total body mass, multiplied by 100. It includes both essential body fat (needed for life and reproductive functions) and storage body fat. Unlike BMI, it gives a clearer picture of your body composition.
Healthy Body Fat Ranges
Ranges vary for men and women:
- Men: 10-20% is often considered fit, while over 25% is classified as obese.
- Women: 20-30% is considered fit, while over 32% is classified as obese.
The U.S. Navy Method
One of the most common and accessible ways to estimate body fat without expensive equipment is the U.S. Navy Method. It uses measurements of height and the circumference of the neck, waist (and hips for women) to estimate body density and fat percentage.
Why Track Body Fat?
Tracking body fat is often more motivating than tracking weight alone. If you are exercising and building muscle, your weight might stay the same, but your body fat percentage will decrease, leading to a leaner and healthier body.
