Understanding Body Fat Percentage

Body fat refers to adipose tissue stored in our bodies. Body fat percentage is the ratio of fat to total body weight expressed as a percentage.

  • Essential fat: Essential for sustaining life such as organ protection, hormone production.
  • Storage fat: Performs functions such as energy storage, body temperature maintenance.
  • Body fat percentage is a more accurate health indicator than BMI.

Navy Method (Circumference Measurement)

Method developed by the U.S. Navy, calculates by measuring neck and waist circumference (adds hip circumference for women). Most practical as it only requires a measuring tape.

Jackson-Pollock Method (Skinfolds)

Method using skinfold calipers to measure thickness of subcutaneous fat at specific locations. High accuracy but requires skilled measurement.

DEXA Scan (Reference)

Most accurate body composition analysis method using X-rays. Only available at hospitals or specialized centers, cannot be measured with online calculators.

Healthy body fat percentage varies by gender, age, and activity level. Generally, men maintain lower body fat percentage than women.
