BY THE NUMBERS
BMR- BASAL METABOLIC RATE
REFERS TO THE NUMBER OF CALORIES
BURNED WHEN TOTALLY INACTIVE.
KEY POINT - WHEN MUSCLES BECOME
LARGER, BMR GOES UP AND BODY FAT GOES
DOWN.
IMPEDENCE
REFLECTS THE BODY’S INHERENT
RESISTANCE TO AN ELECTRICAL CURRENT.
MUSCLE ACTS AS A CONDUCTOR OF THE
ELECTRICAL CURRENT
FAT ACTS AS A RESISTOR.
TBW - TOTAL BODY WATER
THE AMOUNT OF WATER EXPRESSED
IN POUNDS RETAINED IN THE BODY.
COMPRISES BETWEEN 50% - 70% OF
TOTAL BODY WEIGHT.
