Calculating body fat percentage isnt always completely accurate and there are many methods to try. Navy body fat formula boy fat categorization advice on how to reduce body fat and information on precise methods for measuring the percentage of body fat tissue like dexa dual energy x ray absorptiometry bio impedance water displacement ct mri and others. However adp uses air instead of water. Well talk about the healthy range for men and women and the limitations. Adp uses the same principles as the gold standard method of underwater weighing but representing a densitometric method that is based on air displacement rather than on water immersion.
