BMR
Basal Metabolic Rate (BMR) is the amount of energy a body needs in complete
peace to maintain its core functions (eg, a 24-hour bed rest). Basically, this value
depends on weight, height, and age. It is displayed on a diagnostic scale in kcal /
day and is calculated using a scientifically recognized Harris-Benedict formula.
This amount of energy needs your body in any case and must be delivered in the
form of food. Lower energy intake for a long time can lead to health risks.
AMR
Active Metabolic Rate (AMR) is the amount of energy a body consumes in its
active state in one day.
The energy consumption of a person increases with increasing physical activity
and is determined by the diagnostic level by the specified level of activity (1-5).
In order to maintain the current weight, the energy consumed must be supplied
to the body again in the form of food and drink. If less energy is consumed for a
longer period of time than the body consumes, the difference will be mainly offset
by the stored fat reserves and the weight is reduced.
Conversely, if more energy than the calculated Active Metabolic Value (AMR)
is received for a longer period of time, the body is not able to consume excess
energy, stores it in the form of fat, and increases the weight.
Time dependence of results
Remember that only a long-term trend is important. Short-term weight variations
within a few days are typically caused by fluid loss. The importance of results is
driven by changes in total weight and percentage of body fat, body water, and
muscle mass, and also depends on the time period for which these changes will
occur. Sudden changes within a few days need to be distinguished from mid-term
(within weeks) and long-term changes (within months).
As a rule of thumb, short-term weight changes are almost exclusively changes in
body water content, while medium and long-term changes may also affect fat and
muscle mass.
• If you lose weight for a short time, but the amount of body fat increases or stays
the same, you have lost only water - eg. after training, sauna or diet, limited to
quick weight loss only.
• On the other hand, if your medium weight increases and the amount of fat
decreases or stays the same, you might have a valuable muscle mass.
• If you lose weight and body fat at the same time, your diet works - you lose fat.
• Ideally, it is advisable to support your diet with physical activity, exercise or
strength training. In this way you can achieve an increase in muscle mass in the
medium term.
• Body fat, body water or muscle mass can not be summed up (water is also part
of muscle tissue).
