How To Determine Your Body Fat
**********************************************
The minimum body fat percentage considered safe is 5% for
males and 12% for females. The average adult body fat
considered healthy is 15-18 % for men and 22-25 % for women.

There are several methods for assessing body fat:
1. WAIST TO HIP RATIO - divide waist circumference by hip
circumference. A ratio greater than 0.8% is considered to be
a health risk for women. For men, a ratio of 0.95% or higher
is considered a health risk.

2. SKINFOLD MEASUREMENT – as approximately 50% of fat is
stored under the skin, you can measure the skin thickness at
several areas of the body using calipers to indicate your
overall body fat.

3. BIOELECTRICAL IMPEDANCE - a low level of electrical
current is passed though your body by electrodes placed on
your wrist and ankle. The greater the resistance to the
current flow, the greater your percentage of body fat.

4. HYDRODENSITOMETRY - fat is less dense than water, so the
difference between your weight on dry land and your weight
when you are submerged in water is the estimate of your
total body fat. This test is a very accurate measure of
total body fat.
