Body mass index (BMI)

The body mass index (BMI) is a number that is often called upon to evaluate body weight. The figure is cal-
culated from body weight and height. The formula is: body mass index = body weight : height². The measu-
rement unit for BMI is [kg/m²]. According to the BMI, weight is classified for adults (20 years and over) using
the following values:
Category
Underweight
Normal weight
Overweight
Obese (overweight)
Metabolic age
Metabolic age, also known as biological age, may differ from your actual/calendar-based age. It shows your
"internal" age and gives you an indication of your state of health.
Genes play a role here, but also a healthy lifestyle (balanced diet, activity etc.). Your weight also affects your
biological age – the higher your body mass index, the worse it is for your fitness.
Temporal context of the results
Note: Please note that only the long-term trend is important. Brief deviations in weight within a few days
are normally caused by loss of fluids.
The interpretation of the results is based on changes in total body weight, percentage of body fat, body water
and muscle content, as well as on the length of time over which these changes occur.
Rapid changes within the scope of a few days are to be considered separately from medium-term changes (in
the scope of weeks) and long-term changes (months).
It can be said as a basic rule that short-term changes in weight are almost entirely changes in water content,
whereas medium-term and long-term changes may also relate to the fat percentage and the muscle percentage.
• If your weight drops in the short term but your body fat percentage increases or stays the same, you have
only lost water, for example following a training session, visit to the sauna or a diet aimed only at fast
weight loss.
• If your weight increases in the medium term and your body fat percentage drops or stays the same, you
may have built up valuable muscle mass.
• If your weight and body fat percentage both fall at the same time, then your diet is working – you are losing
fat mass.
• Ideally, you should support your diet with physical activity, fitness or strength training. This enables you to
increase your muscle percentage in the medium term.
• Body fat, body water and muscle percentages should not be totalled (muscle tissue also contains com-
ponents made of body water).
