A: Yes, there are:

  • Select a consistent time of day, and stick to it.
  • With an empty bladder
  • When normally hydrated
  • Unclean foot pads may interfere with conductivity.
  • Nylons interfere with conductivity. If it is absolutely necessary to measure in nylons, use a drop of isopropyl (rubbing) alcohol on the foot pads to act as a conductor.
  • Early morning is not recommended because the body is often dehydrated after a night’s sleep.

Once you have established your baseline, monitor body fat about twice a month. Checking body fat more frequently is not beneficial as changes occur slowly over time.

Things that can affect hydration include:

  • Strenuous exercise
  • Recent food intake
  • Diuretics such as caffeine, alcohol, certain medications
