The first level of assessment of your health is knowing your body mass index. So, in this article, we are attaching a Body Mass Index (BMI), Calculator. We also talk about who should and should not use the calculator.
Using the BMI calculator, you can determine how healthy are you? Your weight is normal or obese? You may be underweight or overweight. Both are not good for your health.
Underweight people may have the risks of developing health conditions such as:
- vitamin deficiencies
- decreased immune functions
- irregular menstrual cycles
- growth issues in children
Overweight (obese) people may have high risks of developing health conditions such as:
- type 2 diabetes
- heart disease
- high blood pressure
- certain types of cancer
- fatty liver
- kidney disease
- sleep apnea
- pregnancy issues
- joint problems
So, always have awareness of a healthy lifestyle. The awareness begins from knowing your body mass index. Asses where you stand on your health condition and take timely actions.
You can use the Basal Metabolic Rate (BMR) calculator for correcting your weight. BMR helps to decide on how much calories need be reduced or added every day.
What is Body Mass Index?
How body mass Index is calculated (the formula of BMI)?
The formula for BMI is very simple. The weight in kilograms is divided by the height in square meters. In the case of centimeters divide further by 100 to convert to meters.
The BMI formula is Weight (kg) / [height (m)]2
How to Read Your BMI from the Body Mass Index Chart?
|BMI Readings (Range)||Body Weight|
|less than 19||underweight|
|19 to 24||normal|
|25 to 29||overweight|
|30 to 39||obese|
|above 40||extreme obesity|
Body Mass Index Chart for Men and Women
For the simplicity of reading purposes, we have reconstructed the BMI Chart. The chart published by the National Institute of Health. This table advocates what should be your correct weight based on your height.
Who can use the Body Mass Index Calculator?
Yes, you and I can use the BMI calculator. What we mean is that a BMI calculator is meant only for normal people. Not for the people who are engaged in changing their physical structure for purpose. BMI calculator does not suit for the people like:
- muscle builders
- growing young children
- pregnant women
- women in lactation and
- elderly people
These groups of people’s weights cannot be judged easily. Because it is hard to say they have more muscle or fat in their bodies.
Athletes and bodybuilders may show a higher reading of BMI. The reading is high because they may have more muscle weight than fat weight. This does not mean they are obese or unhealthy.
Similarly, growing young children's weight keeps varying. The elderly people may lose some weight due to aging. Because of these reasons, their BMI reading may show lower. It does not necessarily mean they are unhealthy.
Women’s composition changes during pregnancy and lactation. It affects their weight. In these conditions, BMI readings are not appropriate. It cannot determine they are overweight or not.

How Accurate Is BMI Calculator?
Researchers do argue how accurate is the BMI calculator? They doubt the accuracy of BMI readings on overweight, normal weight, or underweight. They argue this is not the correct way to measure bodyweight fat.
The main reason being that BMI cannot differentiate between muscle and fat. Some people are muscular and have less fat in their bodies. Some have more fat and fewer muscles. This tends to mislead that he or she is overweight (4).
Additionally, BMI cannot know where the fat is deposited in your body. In normal circumstances, the belly fat is more harmful than the fat just under the skin.
Thin people may also have belly fat but BMI may show normal reading. It does not mean they are healthy.
Doctors may use the BMI reading only to have a 1st level information about the patients. Helping them to decide if their patients are at a high, a low or at no risk. The risks in relation to the bodyweight of their patients.
Doctors may also use the other methods in a combination of BMI to determine the health of a patient such as:
- Waist to Hip Ratio (WHR)
- Waist to Height Ratio
- Body Fat Percentage
Using these methods helps to come to a better conclusion. You have to gain or lose weight or you are at the correct weight.
There are other expensive methods also to find fat in our body. Such methods are CT and MRI scans. Doctors seldom use these methods. Unless it deems important depending on the patient’s health condition.
It is good to know what is your BMI. It is a simple calculator. All you need to know is your weight and height. BMI readings help you to determine you are underweight, normal weight or overweight.
By knowing your BMI, you can take timely corrective actions for the right weight for your body. You can assess yourself if BMI readings are high because of fat or muscles. If your muscles are sluggish and you have a bigger belly then mostly you are obese. If your muscles are stronger and not sluggish and your BMI reading is high you shouldn’t be worrying too much.
