What is body fat percentage?
Body fat percentage indicates what proportion of your total weight corresponds to fat tissue. It's a more accurate indicator of body composition than BMI, as it distinguishes between fat and lean mass.
Measurement methods
There are several methods: caliper measurements, bioelectrical impedance, DEXA, and anthropometric methods like the U.S. Navy method. Each has different levels of accuracy and accessibility.
Healthy ranges
Healthy ranges vary by gender. For men: 10-20% is fitness, 6-13% athletic. For women: 20-25% is fitness, 14-20% athletic. Women need more essential fat for hormonal functions.
