Here is a body fat percent chart classification list that I thought people might like to see so they know what category they fall in:

Body Fat Percentage Classifications:

ESSENTIAL FAT
Male: 2 - 4 | Female: 10 - 12

ATHLETES
Male: 6 - 13 | Female: 14 -20

FITNESS
Male: 14 - 17 | Female: 21 - 24

OVERWEIGHT
Male: 18 - 25 | Female: 25 - 31

OBESE
Male: >25 | Female: > 32

Knowing your body fat percentage is good to help you determine if your weight loss goals are realistic. Remember, weight loss doesn't always mean fat loss.

Body fat measurements is a good methods for measuring "weight loss". When someone decides that they want to "lose weight", what they often mean is that they want to lose fat.

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.

There are a number of different ways to measure your body fat. Some of those ways are:

• Body Fat Pinch Test - Special calipers are used to measure folds of skin and fat in several spots on the body and average them. It is not a precise method; a reading of 25 percent body fat could mean an actual number as high as 28 or as low as 22. However, this method only takes a few minutes to do.
  
• Bioelectrical Impedence Test - You lie down, a technician attaches electrodes to one hand and one foot, and a harmless radio-frequency pulse is run through the body to measure its water content. That number provides a guide to body fat with an error of 2 or 2 1/2 percentage points. But exercise and liquid intake before the test can skew results. This test also only takes a few minutes.
  
• Immersion Test - So far the "gold standard" of body-fat measurement, this test requires you to expel the air from your lungs and get dunked into a pool–half a dozen times. It under or overestimates body fat by only 1 percentage point. This test can last up to an hour.
  
• Bod Pod - An egg-shaped chamber that offers precision without pain. You step in, sit for 20 seconds, and that's it. The chamber measures air displacement, which can be converted to relative fat when weight is factored in, since muscular people are denser. This is found at only a few big hospitals, but test show it is as good as immersion and only takes a few minutes.
