Evaluation Of Results - Beurer BF 400 Instructions For Use Manual

6. Evaluation of results
Weight:
Your weight is compared with the BMI (Body Mass Index). It is calculated using the following formula: BMI
= Weight in kg / (height in m)² .
Underweight Normal weight
<18,5 18,5 - 25
Note that with very muscular physiques (body builders), the BMI interpretation will show overweight. The
reason for this is that no account is taken of well above average muscle mass in the BMI formula.
Body fat percentage
The following body fat percentages are for guidance (contact your physician for further information).
Man
Age very good good
10–14 <11% 11–16%
15-19 <12% 12-17%
20-29 <13% 13-18%
30-39 <14% 14-19%
40-49 <15% 15-20%
50-59 <16% 16-21%
60-69 <17% 17-22%
70-100 <18% 18-23%
A lower value is often found in athletes. Depending on the type of sports, training intensity and physical
constitution, values may result which are below the recommended values stated.
It should, however, be noted that there could be a danger to health in the case of extremely low values.
Body water:
The body water percentage is normally within the following ranges:
Man
Age poor good
10-100 <50 50-65%
Body fat contains relatively little water. Therefore persons with a high body fat percentage have body wa-
ter percentages below the recommended values. With endurance athletes, however, the recommended
values could be exceeded due to low fat percentages and high muscle percentage.
Body water measurement with this scale is not suitable for drawing medical conclusions, for example con-
cerning age-related water retention. If necessary ask your physician.
