Tracking your Body Fat Percentage

Sunday, February 01, 2009

In my experience, nothing is more deceptive than scale weight. Your clothes could be fitting better but your scale weight may not drop that significantly especially if you are on a weight-training program.

Some of you may have bought a body fat scale that claims to measure your body fat. You might be surprised to learn how the scale works. What it does is shoot a small electric current from the sole of your left foot through your body and completes the circuit with your right foot (don't worry you won't light up like a bulb - the current is tiny).

The strength of the current is proportional to both the fat content but also proportional to your hydration level at that point in time. So attempting to measure your body fat percentage with one of these scales is sort of like measuring your waist circumference with your clothes on - it would vary with what you are wearing. So your displayed body fat percentage can vary wildly with your hydration level and because muscles store more water, it can make an extremely muscular person (with a low body fat percentage) appear to be in its obese range. This can be disappointing to the best of us!



My advice would be to buy a pair of fat callipers like the one made by Accu-measure. They are much more accurate than the electronic body fat meters and at under 10 bucks, it's a great addition to your fitness tools.

    I have a Caliper. I also use an equation that another member gave me here on Spark.
====================
B
ody fat % equation. Accuracy +/- 3%.

Women over 30
HIPS + THIGH – (2 x Calf) – WRIST = % Body Fat
Weight x %BF = Fat #
Weight – Fat # = Lean Body Mass
LBM / .78 = Ideal Body Weight

Women under 30
HIPS + (.80)THIGH – (2 x CALF) – WRIST = % Body Fat
Weight x %BF = Fat #
Weight – Fat # = Lean Body Mass
LBM / .80 = Ideal Body Weight

Men under 30
waist + (1/2)hip – (3 x forearm) – wrist = % Body Fat
Weight x %BF = Fat #
Weight – Fat # = Lean Body Mass
LBM / .90 = Ideal Body Weight

Men over 30
waist + (1/2)hip – (2.7 x forearm) – wrist = % Body Fat
Weight x %BF = Fat #
Weight – Fat # = Lean Body Mass
LBM / .85 = Ideal Body Weight

NOTE: If you are extra muscular use the under 30 calculations to get a more accurate BF%

I know if you don't use the caliper right, it can give a false reading. So I'm not sure which to use (caliper or equation). I stopped using my hydro-scale b/c my Body Fat% was all over the place, depending on the day.

    "Abs"olutely!!! I do that too because there is NOTHING like killin' yourself at the gym (or where eva) and then NOTHING comes off ... Keep pushin' through and your body WILL follow.

Oh and about the Power 90 X ... Yea, it does a body good. :P That is a pic of me two years ago ( 7 months after I had baby # 6) ... emoticon
I Love free weights too.

Keep pressin' play or get to the gym and Work IT !!!
