The calculation of calories needed for daily weight maintenance is done by multiplying the RMB value by an activity coefficient. This coefficient differs according to many factors: place of work, weekly frequency of training, type of training, genetics, etc. Two people with similar characteristics may have different total caloric needs due to these deciding factors.
Please keep in mind that these are theoretical calculations, each person is different, values can change depending on individual metabolism, so it is very important to find the actual caloric maintenance. Calorie calculation is not enough to optimize metabolic processes, although it is important to know the daily caloric needs, due to hormonal response, a very important factor is the source of these calories, i.e. the quantity and quality of Macronutrients consumed daily. Once you know your daily calorie needs, you can start “tracking” them.
