How to Calculate BMI ?

Multiply your Height by itself
Divide weight with above answer

BMI = weight in KG ÷ height (m) * height (m)

For Example: If an adult weight is 78 kg and his height is 175 cm then his BMI would be as follows: -

175 cm (1.75 m) individual weighing 78 kg,
BMI = 78/ 1.75 * 1.75 = 78/ 3.06 = 25.49

For Adults aged 20 year and above following are the BMI Values:

BMI Value	Category
Below 18.5	Underweight
18.5–24.9	Normal weight
25–29.9	Overweight
30–35	Obese
Over 35	Morbidly obese

BMR- Basal Metabolic Rate

BMR tells you how many calories your body need for normal daily functioning in a resting state. We have multiple organs that keep working on their own even when we are not doing any physical activity. For example, our heart pumps blood without we asking him to do, lungs help in breathing, kidney is working continuously to clean blood, Subconscious mind is working, tongue, mouth, stomach, intestines, liver all parts are doing their job. These all activities consume energy. So, there is a minimum energy that every human body spends to carry out these all-basic activities.

Minimum amount of energy that your body need to carry out these basic life sustaining functions is call “Basal Metabolic rate”. It’s calculated by taking your height, weight, age and sex into consideration. It can be manually calculated by Mifflin-St Jeor formula (Most commonly used and accurate formula) as given below:

For Females	BMR= (9.99Weight in Kg) + (6.25height in cm) - (4.92*age in years)-161
For Males	BMR= (9.99Weight in Kg) + (6.25height in cm) - (4.92*age in years) + 5

Once you got to know your BMR, you will understand minimum basic calorie requirement of your body to maintain your weight.
