How do I calculate lean body mass?
If you would like to manually calculate your lean body mass you can do so by subtracting your body fat in pounds from your total body weight. You can determine the amount of body fat in pounds by multiplying your weight by the body fat percentage. For example, a 200lb person with 20% body fat would have 40 lbs of fat (200 X .20). His lean body mass would then be 200-40= 160lbs.
How is body fat calculated?
Omron’s Fat Loss MONITOR with Scale estimates the body fat percentage by using the Bioelectrical Impedance (BI) Method. Muscles, blood vessels and bones are body tissues having a high water content that conducts electricity easily. Body fat is tissue that has little electrical conductivity. The Fat Loss MONITOR with Scale sends an extremely weak electrical current of 50 kHz and less and 500 µA through your body to determine the amount of fat tissue. This weak electrical current is not felt while operating the Fat Loss MONITOR with Scale.
Is there a recommended time to take a measurement of your body fat?
We recommend you take the measurement in the morning before you exercise, eat, drink or take a shower. This will give you opportunity to develop a trend and a good comparison by day.
