Hello, I am interested in understanding the difference between BMR and RMR (resting calories). Are resting calories important for any calculations? On my Garmin watch, after entering my personal parameters, only resting calories are displayed and not BMR. Thank you.

BMR is the amount of energy expended in a resting state in a thermally neutral environment while fasting - energy expenditure in this state is solely determined by the functioning of vital organs. RMR (resting metabolic rate) is essentially the same value, but measured under less strict conditions - it represents the number of calories the body burns at rest (i.e., without performing any physical activity). In practice, it is somewhat irrelevant which value you use, because neither is accurate regarding the conditions of real measurement and always deviates from reality (it is just a question of to what extent). Furthermore, in the area of attempting to monitor energy balance, keep in mind that calculations of the amount of energy in a daily diet can show a variation in value of even a few hundred calories. These facts tell us that addressing energy balance does make sense, but only in a general sense, because you can never calculate exact numbers. The decisive process is monitoring the body's manifestations, which alone provides true information following dietary changes...
