How does a body fat monitor work?

A body fat monitor measures the travel of an electric current.

A body fat monitor measures how easily a small and safe electric current travels
through your body.

The technical term for this is bioelectrical impedance analysis (B.I.A.).

CAUTION: DO NOT USE B.I.A. SCALES/MONITORS IF YOU HAVE AN IMPLANTED MEDICAL DEVICE SUCH AS A PACEMAKER.

  • The small electric current travels between the electrodes (silver grips) you place
    your hands on.
  • Water is a good conductor of electricity. Therefore, the electric current travels easily (or with less resistance) through parts of your body composed mostly of water.
  • Muscle is composed mostly (approximately 75%) of water. Therefore, the easier the current travels, the more muscle and less fat you are estimated to have.

The electric resistance and other information you enter into the monitor (height, weight, gender, and age), is used in a formula to estimate your percent body fat.

What should my percent (%) body fat be?
