Please consult your doctor before you start a body weight management program. Tanita is not responsible for the
target body fat ratio.
BMI:Body Mass Index is a height to weight
ratio, and is calculated by the following
formula:
Weight (kg)
Height (m2)
Desirable Range 18.5 - 24.9
IMPEDANCE:Impedance reflects the body’s
inherent resistance to an electrical current.
Muscle acts as a conductor of the electrical
current, adipose tissue acts as a resistor.
BMR:Basal Metabolic Rate represents the
total energy expended by the body to
maintain normal functions at rest such as
respiration and circulation.
FAT MASS:Total weight of fat mass (in kg ,
lb) in the body.
FAT%:The percentage of total body weight
that is fat.
FFM:Fat Free Mass is comprised of muscle,
bone, tissue, water, and all other fat free
mass in the body.
PW:Predicted weight
Calculated weight for the given Target
BF%.
FAT TO LOSE/GAIN:
Calculated fat mass to lose or gain to
achieve the Predicted Weight.
PFM:Predicted fat mass
Caluculated fat mass for the given Target
BF%.
TBW:Total Body Water is the amount of
water (expressed as lb, kg, or st.lb) retained
in the body. TBW is said to comprise
between 50% - 70% of total body weight.
Generally, men tend to have higher water
weight than women due to a greater
amount of muscle.
PMS:Predicted Muscle Mass
means bone-free lean tissue mass (LTM)
