BMR Calculator

An integral property of all biological systems is the exchange of substances and energy between the body and the environment. Metabolism is the process of metabolism of substances that enter the body, as a result of which more complex or, conversely, simpler substances can be formed from these substances. In other words, it is a set of physical, chemical and physiological processes of transformation of substances and energy in the human body and exchange between the body and the environment. Basal metabolism (basal) or basal metabolism is the minimum amount of calories (energy) that your body burns at rest, which is necessary for the body to function normally. Basal metabolism is the minimum amount of energy required to ensure normal functioning of the body under standard conditions.

Basal metabolism is the minimum amount of energy expended by the human body to maintain its own life and vision at rest (this energy is spent on breathing, blood circulation and digestion of food). The basic (basal) metabolism is determined by the amount of heat per unit mass of the human body per day, and is the basal metabolic rate (BMR). Various factors, such as age, gender, health, exercise, and especially the level of thyroid function, can significantly affect the rate of basal metabolic rate. BMR depends mainly on age, height, weight, gender and ranges from 66 to 75 percent of the daily calorie intake. The easiest way to get this value is to use the Base Metabolism Calculator.
