What Is Body Fat Percentage & Body Composition?
Body fat percentage is the proportion of your total body weight that consists of fat tissue. It's expressed as a percentage and provides a more accurate assessment of body composition than weight or BMI alone. Understanding your body fat percentage is crucial for setting realistic fitness goals and tracking progress more effectively than traditional weight measurements.
- Essential Fat: Required for basic physiological functions (2-5% men, 10-13% women)
- Storage Fat: Energy reserves stored throughout the body
- Subcutaneous Fat: Fat stored under the skin
- Visceral Fat: Fat stored around internal organs
- More accurate than BMI for assessing health
- Better indicator of fitness level
- Helps track progress during weight loss/muscle gain
- Identifies health risks associated with excess fat
