Basal Metabolic Rate - BMR Calculator calculates the Basal Metabolic Rate - Amount of calories burned at rest in a neutrally temperate environment to keep body functioning like breathing, blood circulation, nerve function etc. BMR affects the rate a person burns calories to lose, gain or maintain weight. BMR decreases with age and it accounts of more than half calories we burn per day.

### What is BMR?

Basal Metabolic Rate (BMR) is the minimal amount of energy spent by our body at rest in a neutrally temperate environment. That means, when we are resting or doing almost no amount of work, our body still needs some energy to keep our body functioning. Some of those metabolic functions are blood circulation, brain and nerve function, functioning of vital organs like heart, Kidneys, lungs etc.

### How Basal Metabolic Rate (BMR) is affected?

There are four important factors which affect the basal metabolic rate (BMR):

• Weight/Mass
• Height
• Age
• Sex

#### Correlation of Basal Metabolic Rate with these factors:

• Weight and Height are directly proportional to BMR. That means the taller and heavier you are, the more your body has to function to maintain the BMR
• BMR decreases with old age
• BMR for Men is higher than BMR for women. That's In the BMR calculator, we have a different BMR calculator for Men than women.

### Formula for calculating BMR

If you want to calculate the BMR on pen and paper statistically then here is the general BMR formula, also called as Mifflin- St. Jeor equation, the most commonly used BMR calculator.

• BMR Calculator for Men:
BMR = 10 * weight (kg) + 6.25 * height (cm) - 5 * age(y) + 5
• BMR Calculator for Women:
BMR = 10 * weight (kg) + 6.25 * height (cm) - 5 * age(y) – 161
