Body Fat Percentage
How the Body Fat Calculator Works
This body fat calculator uses the U.S. Navy circumference method, a widely used and scientifically validated formula to estimate body composition. Unlike BMI, which only considers weight and height, this method accounts for where your body stores fat, providing a more accurate picture of your fitness level.
Understanding Your Results
The calculation differs between men and women because biological fat storage patterns vary. Men typically store fat in the abdominal region (waist), while women store more fat in the hips and thighs.
| Category | Men (%) | Women (%) |
|---|---|---|
| Essential Fat | 2-5% | 10-13% |
| Athletes | 6-13% | 14-20% |
| Fitness | 14-17% | 21-24% |
| Average | 18-24% | 25-31% |
| Obese | 25%+ | 32%+ |
Tips to Reduce Body Fat Percentage
- Strength Training: Lifting weights builds lean body mass, which increases your resting metabolic rate.
- High-Protein Diet: Protein has a high thermic effect and helps preserve muscle during fat loss.
- Caloric Deficit: To lose fat, you must consume fewer calories than you burn, but avoid extreme deficits to protect metabolic health.
- Sleep Hygiene: Lack of sleep increases cortisol and ghrelin, making it harder to burn fat.
Is the Navy Method Accurate?
While DEXA scans and hydrostatic weighing are the gold standards, the Navy Method is surprisingly accurate (within 3-4% margin of error) for a free, non-invasive tool. It is much more useful than a standard scale for tracking progress over time.
