Do you have any questions?
Are multi-frequency bioimpedance analyzers more accurate than single-frequency devices?
Yes, because only the multi-frequency devices allow for a measurement according to the Cole-Cole model, which takes into account the non-homogeneity of the tissues. A minimum of 3 frequencies is necessary to obtain a reliable result according to the Cole-Cole model. The Biody Xpert and Biody Coach equipment use 5 frequencies.
Are dual frequency bioimpedance analyzers equivalent to multi frequency?
2 frequencies do not allow, among other things, the function of differentiating between intra and extra cellular water and total water. Some manufacturers often have this type of device (with 20 and 100khz), but they are no more interesting than a single frequency device and are often more expensive than the eBIODY range of bioimpedance analyzers.
Where are the eBIODY bioimpedance analyzers and software designed?
The eBIODY bioimpedance analyzers and interpretation software are designed and manufactured in France by the company AMINOGRAM. They are also certified in France by the GMED verification body, a metrology and testing laboratory. The basic evaluations on the equipment are also carried out in France.
Is it possible to assess body composition segment by segment (segmental analysis)?
Yes, with technologies such as DEXA, it is possible with medical imaging to measure limb segments separately.
In bioimpedance analysis, this is often a commercial artifice because the weight or volume of each of the 5 segments must be identified beforehand to measure them and bioimpedance analysis does not allow this. The devices that promise this kind of result work on the basis of a fixed type of template representing the trunk, legs and arms. On a standard individual, the result will be good, but as soon as you deviate from the standard, the results are very random. The evaluations carried out in laboratories by the eBIODY teams show differences of +/- 7 kg on the trunk and +/- 3 kg on one leg, or inversions of the proportions of fat mass between legs and arms depending on the devices.
Is it possible to assess visceral fat by bioimpedance analysis?
Bioimpedance analysis is not currently able to differentiate between subcutaneous and visceral fat. The results given by some competing devices are not due to the measurement performed by bioimpedance analysis, but to a prediction based on a cross-referencing of data. For example, it is now well known that the ratio of heel circumference to hip circumference is of interest, but is a very insufficient data to predict the presence of visceral fat.
Do consumer 'scales' measure the whole body?
No, they only measure the lower body. As a result, they overestimate the body fat of gynoid people and underestimate the body fat of android people.
Do whole body monitors require a foot/hand measurement?
Yes, in order to perform a full body measurement it is necessary for the current to flow from one end of the body to the other.
Does the age of the person matter in the results of the body balance analysis?
