BMR Calculator
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
