Understanding Body Fat Percentage
Body fat percentage is a valuable indicator of overall health and fitness. Unlike BMI (Body Mass Index), which only considers height and weight, body fat percentage distinguishes between fat mass and lean body mass, providing a more accurate assessment of your health status.
Why Body Fat Percentage Matters
Monitoring your body fat percentage is crucial for several reasons. Excess body fat, particularly visceral fat around organs, is associated with increased health risks including heart disease, diabetes, and certain cancers. Conversely, too little body fat can also cause health issues, including hormonal imbalances and decreased immune function.
How to Use This Calculator
Our body fat calculator uses the U.S. Navy method, which provides accurate estimates based on circumference measurements. To get the most accurate results:
- Use a flexible measuring tape
- Measure against bare skin
- Ensure the tape is snug but not compressing the skin
- Take measurements at the end of a normal exhale
Interpreting Your Results
Body fat percentage categories vary by gender and age. Generally, for men, 6-24% is considered healthy, while for women, 16-30% is typically healthy. Athletes often have lower percentages, while older adults may have slightly higher healthy ranges.
