BMR (basal metabolic level), Basic metabolic rate, is an indicator that shows us how many calories our body consumes in a day.
Metabolism includes the processes the body needs to function. Basal Metabolic Rate (BMR) is the amount of energy per unit time that a person needs to maintain the body at rest. Some of these processes are breathing, blood circulation, controlling body temperature, cell growth, brain and nerve function and muscle contraction. Basal Metabolic Rate (BMR) affects the rate at which a person burns calories and ultimately whether that person maintains, gains, or loses weight.
Basal Metabolic Rate accounts for 75% (on average) of the calories we consume each day. On the contrary, the Active Metabolic Rate calculates the energy needed by our body when it is in some physical activity and varies based on the lifestyle we lead (eg: sedentary, sports, etc.).
Metabolic rates beyond physical exercise are proportional to a person's sex, weight, height, as well as age and are calculated through mathematical formulas.
The mathematical formula for calculating Basic Metabolic Rate is as follows:
Women: basal metabolic rate = 655 + (9.6 x weight in kilograms) + (1.8 x height in centimeters) – (4.7 x age in years)
Men: basal metabolic rate = 66 + (13.7 x weight in kilograms) + (5 x height in centimeters) – (6.8 x age in years)
At the same time, to calculate your Active Metabolic Rate you should first choose the type and frequency of your daily physical activity which is divided into 5 levels.
- Very Small – Infrequent Exercise BMR x 1.2
- Moderate – Exercise up to 3 times per week BMR x 1,375
- Intense – Exercise 3-5 times a week BMR x 1.55
- Daily – Exercise every day BMR x 1,725
- Athletic – Very intense exercise every day BMR x 1.9
In this way, you can easily calculate your body's daily energy needs, i.e. calories, so that you know how much energy you need to take in to maintain, increase, or decrease your body weight.
