### What is BMR Calculator?

BMR value will be useful to maintain your body or to loss your weight or to gain weight.

BMR value will be depend on the following factor.

• Sex
• Weight
• Height
• Age
• Genetic Factors

#### How much calories you need in a day ?

Excercise = None, then your daily calorie needs will be your BMR value

Excercise = Very Little, then your daily calorie needs will be your BMR value * 1.2

Excercise = Light, then your daily calorie needs will be your BMR value * 1.375

Excercise = Moderate, then your daily calorie needs will be your BMR value * 1.55

Excercise = Hard, then your daily calorie needs will be your BMR value * 1.725

Excercise = Non Stop, then your daily calorie needs will be your BMR value * 1.9

### BMR Calculator Formula

Mifflin-St Jeor Formula:

For men:

BMR = 10 × Weight (Kg) + 6.25 × Height (Cm) - 5 × Age + 5

For women:

BMR = 10 × Weight (Kg) + 6.25 × Height (Cm) - 5 × Age - 161

Revised Harris-Benedict Equation:

For men:

BMR = 13.397 × Weight (Kg) + 4.799 × Height (Cm) - 5.677 × Age + 88.362

For women:

BMR = 9.247 × Weight (Kg) + 3.098 × Height (Cm) - 4.330 × Age + 447.593

### Example

Example 1

John's age is 29 and height is 157 cm and weight is 73 kg then the BMR will be calculated in the following manner

Here is how John's BMR is calculated

BMR = 10 × Weight (Kg) + 6.25 × Height (Cm) - 5 × Age + 5

BMR = 10 × 73 + 6.25 × 157 - 5 × 29 + 5

BMR = 1571 Caloris/Day

Example 2

Charlie's age is 29 and height is 5 feet and 2 inch and weight is 160 lbs then the BMR will be calculated in the following manner

Here is how Charlie's BMR is calculated

BMR = 9.247 × Weight (Kg) + 3.098 × Height (Cm) - 4.330 × Age + 447.593

BMR = 9.247 × (160/2.2046) + 3.098 × (5/0.032808 + 2/0.39370) - 4.330 × 29 + 447.593

BMR = 1404 Caloris/Day
