Your lean body mass is your total bodymass minus your fat storage. This can be calculated by first determining your body fat percentage (BFP) using one of the following methods:
Bioelectrical Impedance Analysis (BIA)
A very low level electrical signal is sent through the body - normally by standing on sensors on a body fat monitor. The signal travels quickly through lean tissue, which has a high percentage of water and is therefore a good conductor of electricity, and more slowly through fat, as fat has a lower percentage of water and is therefore a poor conductor of electricity. Bioelectrical Impedance devices use the information from this signal to work out body fat percentage.
Skinfold Measurements
This method involves a skinfold callipers to pinch predetermined sites on the body. The tongs pinch the skin, pulling the fat away from the muscles and bones. A gauge on the callipers measures the thickness of that pinch.
It is recommended that this test is carried out by a professional and should be repeated to verify measurements. To make the test reliable you should not exercise beforehand. Exercise makes your blood travel to your skin to help you cool down and this causes the skin to swell, making your test inaccurate.
Hydrostatic Weighing Tanks
This method is the most accurate but also the most uncomfortable. You sit on a scale in a large tank of water and exhale all the air out of your lungs, then submerge yourself in the water completely. You stay underwater for 5 seconds, while your underwater weight is recorded. You have to make sure no air is trapped in your lungs, otherwise the test will be inaccurate and your results will produce a higher BFP.
Infrared Interactance
This technique involves a different coloured light, which is shone onto the skin surface at selected areas. The spectrum of the wavelengths reflected is analysed by a computer. The lean muscle to fat ratio at the test areas can be calculated as fat and lean tissue have different interactive spectra. This method, though, is not very reliable.
A 90 kilogram (198 lbs) individual with a BFP of 15% (for example) would have a lean body mass of 168 lbs. So this individual's protein intake should be at a level of 168 grams (minimum) per day, based on one gram per pound of lean body mass.
Like I said before, it may not seem a big problem for some people but when you consider that one gram of protein is 4 calories, the differnce between 168 grams and 200 grams can slowly begin to add up. This is especially true when your BFP starts to go up and you are using your total bodyweight as a reference point as to how much protein you should be consuming. If you use your total bodyweight as a reference instead of your lean body mass then you will have a difficult time in consuming that much protein in addition to having to increase it yet further because your total bodyweight has, for some strange reason, lol, gone up even further.
