Skinfold analysis and hydrostatic weighing are advanced methods of measuring body fat with different levels of accuracy.
Skinfold analysis is a method of measuring body composition by using skin calipers to measure the thickness of skinfolds at various sites on the body. This information is then used to estimate body fat percentage by plugging the measurements into an equation.
Hydrostatic weighing is another technical means of measuring body fat, where a person is weighed both dry and underwater to determine body density and calculate body fat percentage.
While skin calipers are affordable and portable, hydrostatic weighing is considered the 'gold standard' for accuracy in body fat measurement, with a margin of error of around 1-2%.
