Body fat percentage can be calculated using various methods, including: 1. Skinfold measurements: Calipers are used to measure skinfold thickness at specific sites on the body. These measurements are then used in formulas to estimate body fat percentage. 2. Bioelectrical impedance analysis (BIA): BIA devices measure the electrical impedance of body tissues to estimate body composition, including body fat percentage. 3. Dual-energy X-ray absorptiometry (DEXA): DEXA scans use X-ray technology to provide a precise measurement of body fat percentage, bone density, and muscle mass. 4. Hydrostatic weighing: This method involves measuring body weight in water to estimate body density and, consequently, body fat percentage. 5. Air displacement plethysmography (ADP): ADP devices, such as the Bod Pod, measure body volume to estimate body composition. It's important to note that each method has its own limitations and accuracy may vary. Consulting with a healthcare or fitness professional can provide more information on the best method for your specific circumstances.
