Understanding Body Fat Percentage

Body fat percentage represents the proportion of fat tissue to your total body weight. Unlike BMI, which only considers height and weight, body fat percentage provides a more accurate assessment of body composition by distinguishing between muscle mass and fat mass.

The U.S. Navy method is widely used because it’s practical, requires only basic measurements, and provides reasonably accurate estimates for most people. This method is particularly useful for tracking fitness progress, athletic training, and general health monitoring.

• Consistency in measurement technique is key for tracking progress over time
