Understanding Body Fat
What Body Fat Percentage Means
Body fat percentage represents the proportion of your body weight that is composed of fat. It is a more accurate indicator of health than BMI alone because it accounts for body composition.
Essential vs. Storage Fat
Essential fat is necessary for normal physiological function, including hormone production and organ protection. Storage fat is excess fat that accumulates in adipose tissue and can increase health risks when present in excess.
Measuring Body Fat
The US Navy method uses body measurements to estimate body fat. Other methods include skinfold calipers, bioelectrical impedance analysis (BIA), and DEXA scans. Each method has different levels of accuracy.
Health Implications
High body fat increases risk of cardiovascular disease, diabetes, and certain cancers. Too little body fat can disrupt hormone balance and reduce immune function. Maintaining a healthy range is key.
