The Body Fat Calculator will give an approximation of your current body fat levels. We strongly encourage trainees to purchase Body Fat Calipers for a much more accurate reading. Understanding your Body Fat levels Your body fat percentage is simply the percentage of fat your body contains.  If you are 150 pounds and 10% fat, it means that your body consists of 15 pounds fat and 135 pounds lean body mass (bone, muscle, organ tissue, blood and everything else). A certain amount of fat is essential to bodily functions.  Fat regulates body temperature, cushions and insulates organs and tissues and is the main form of the body's energy storage.  The following table describes body fat ranges and their associated categories: *General Body Fat Percentage Categories Classification Women (% fat) Men (% fat) Essential Fat 8-10% 2-4% Athletes 10-15% 6-13% Fitness 15-25% 14-17% Acceptable 25-31% 18-25% Obese 32% plus 25% plus Get your body fat percentage here (Pop Up Window will open)  Need a more accurate body fat reading?
