Abstract: This health indicator measuring device includes an arithmetical operation means for computing data of a lean body per body height or a data of a body fat per body height on the basis of the respective data of body weight, body fat and body height. The health indicator measuring device has the capability of measuring a qualitative aspect or a quantitative aspect of muscle of a person to be measured and outputting indicators of a health year equivalent and an advice data on practical fitness for health related to the function of the body measured.

Abstract: Disclosed is a separable fat scale including a body weight measuring part for detecting a body weight of a person under test who mounts a weighing platform; electrode parts having thereon at least a pair of electrodes to electrically contact soles of feet of the person under test and formed separately from the weighing platform; an impedance measuring part for measuring impedance of the person under test through his/her soles contacting the electrodes; an input part for inputting personal data including information about physical characteristics of the person under test such as sexuality, age and body height; an arithmetic part for calculating a proportion of body fat in the body of the person under test and/or weight of the body fat under impedance signals obtained from the impedance measuring part, load signals obtained from the body weight measuring part and the personal data input; and a data output part for outputting the calculated proportion of body fat in the body and/or weight of the body fat, wherei
