BMR Full Form is **Basal Metabolic Rate**. BMR is the value of calories that our body needs to function. This is a measurement of a person’s energy during physical, physical and emotional rest in 24-hour period. BMR tell, how much calories is required in a whole day. You would know that for an average person, around 1500-2000 calories is considered sufficient for his work. And if you work hard, or you are overweight, then you need more calories, which depends on these four things.

- Age
- Weight
- activity
- Gender

BMR gives you an estimate of calories that you burn when you at complete rest for around 24 hours. The metabolic rate is usually less than BMR during sleep.

**CALCULATE BMR IN MEN AND WOMEN**

There is one formula which is used to calculate BMR in men and women, which is given below.

**P= (10.0 x m/1 kg) + (6.25 x h/1cm) – (5.00 x a/1 year) + s**

- P= total heat production while at rest (BMR)
- m= weight of a person in kilograms
- h= height of a person in centimeters
- a= age of a person in years
- s= constant (+5 for males and -161 for females)

**For example:** let us calculate BMR of a 35 year old Female who is 180 cm tall and weighs around 90 kg.

**On applying Formula-**

P= (10.0 x 90) + (6.25 x 180 cm) – (5.00 x 35) – 161

= 900 + 1125 – 175 – 161

= 2025 – 336

= 1689

So, this person burns 1689 calories while he is resting for 24 hours.
