Body fat percentage shows what portion of your weight is fat. Healthy ranges are 10-20% for men and 18-28% for women. Body fat percentage is a more accurate health indicator than BMI because it distinguishes between muscle and fat mass. You can reduce it through nutrition, cardio, and strength training.

What is a healthy body fat percentage?

For men, 10-20% is considered healthy, while for women it's 18-28%. Athletes typically have lower percentages (6-13% for men, 14-20% for women), while essential fat levels are around 2-5% for men and 10-13% for women.

How accurate is the US Navy body fat calculator?

The US Navy method is about 3-4% accurate when measurements are taken correctly. It's more accurate than BMI but less precise than DEXA scans or hydrostatic weighing. Results work best for tracking changes over time.

What's the difference between BMI and body fat percentage?

BMI only uses height and weight, so it can't tell muscle from fat. Body fat percentage actually measures how much of your weight is fat versus lean mass, making it way more useful for tracking real fitness progress.

How can I reduce my body fat percentage?

Create a calorie deficit through diet, do regular cardio (3-4 times weekly), add strength training to preserve muscle, get enough protein (0.8-1g per pound of body weight), and stay consistent for at least 8-12 weeks.

Where should I measure my waist for body fat calculation?

Measure at belly button level, not where your pants sit. Stand relaxed, breathe normally, and measure after exhaling. Keep the tape snug but not tight, and measure at the same time of day for consistency.

Can you be overweight with low body fat?

Yes, if you have significant muscle mass. Bodybuilders and athletes often have high BMI scores but low body fat percentages. This is why body fat percentage is better than BMI for evaluating actual health and fitness.
