I bought me to stay right up to date my progress for my muscle building program (muscle weighs more than fat, so the body weight is an inaccurate size).
Showing: weight, BMI, body fat (in%), muscle mass (in%), daily turnover in calories and visceral fat (a dimensionless number) / each of the current and the last measured value
To get to "tangible" value, I've tinkered an Excel spreadsheet, the absolute from the percentages calculated.
WHAT TO CONSIDER:
The bioimpedance analysis does not measure body fat or muscle mass but approaches to them by the water content of the body tissue is measured by resistance measurement.
This means in plain text
- Wet hands, feet, skin distort the result
- Hydration falsifies the results (how much liquid was drunk)
- Stomach / intestinal contents falsified the result
WHAT TO DO?
I've become accustomed in the morning to empty my bladder immediately after getting up and going naked on the scales, thus can be many varying factors control or exclude.
The allusion to Excel spreadsheet can then recognize and also represent measurement error as such and the trend.
CONCLUSION
Who knows how to use bio-impedance and evaluates the measured values over a longer period receives a very good measuring instrument -> buy recommendation
