Little influence can be exerted on bone mass, but it will vary slightly within the influencing factors 
(weight, height, age, gender). Bone mass trend displays and interpretations are not available and 
there are no recognised guidelines or recommendations relating to bone mass measurement.  

BMR 

The basal metabolic rate (BMR) is the amount of energy required by the body at complete rest 
to maintain its basic functions (e.g. while lying in bed for 24 hours). This value largely depends 
on the weight, body size and age of the individual and is displayed on the diagnostic scale in 
kcal/day units using the scientifically recognised Harris-Benedict formula. 
Your body requires this amount of energy in any case and it must be reintroduced into your bo-
dy in the form of nutrition. Failing to supply the body with the necessary amount of calorific en-
ergy can cause serious health problems. 

AMR 

The active metabolic rate (AMR) is the amount of energy required daily by the body in its active 
state. The energy consumption of a human being rises with increasing physical activity and is 
measured on the diagnostic scale in relation to the degree of activity entered (1-5). 
To maintain your existing weight, the amount of energy used must be reintroduced into the bo-
dy in the form of food and drink. If less energy is introduced than is used over a longer period of 
time, your body will obtain the difference largely from the amount of fat stored and your weight 
will decrease. If, on the other hand, over a longer period of time more energy is introduced than 
the total active metabolic rate (AMR) calculated, your body will be unable to burn off the excess 
energy, and the excess will be stored in the body as fat and your weight will increase. 

Results in relation to time 

Remember that only long-term trends are important. Short-term fluctuations in 
weight over a few days are usually the result of a loss of fluid. 

The interpretation of the results will depend on changes in your overall weight and body fat, bo-
dy water and muscle percentages, as well as on the period during which these changes take 
place. Sudden changes within days must be distinguished from medium term changes (over 
weeks) and long term changes (months). 
A basic rule is that short term changes in weight almost exclusively represent changes in water 
content, whereas medium and long term changes may also involve the fat and muscle percent-
ages. 

•

  If your weight reduces over the short term, but your body fat percentage increases or 

remains the same, you have merely lost water – e.g. after a training session, sauna 
session or a diet restricted only to rapid weight loss. 

•

  If your weight increases over the medium term and the body fat percentage falls or 

stays the same, then you could have built up valuable muscle mass. 

•

  If your weight and body fat percentage fall simultaneously then your diet is working – you are 

losing fat mass.  

•

  Ideally you should support your diet with physical activity, fitness or power training. This 

way you can increase your muscle percentage over the medium term. 

•

  Body fat, body water or muscle percentages should not be added (certain elements of 

muscle tissue also contain body water).
