When you start your fitness journey, one of the first matrices you have comes BMI or Body Mass Index. This is a popular tool for evaluating your health based on your weight and height. But is it really accurate? How is it calculated? And does that all? In this blog, we will break everything needed to learn about BMI – including benefits, limitations and how it fits into your personal health goals.
What is BMI and Why Does It Matter?
BMI (Body Mass Index) is a numeric value calculated based on weight and height. It helps classify your body shape in health risks such as low weight, normal, obesity or overweight.
Formula Is Simple:
BMI = weight (kg) (height) (square)
Why It Does Matter:
Healthcare professionals and fitness experts use BMI as a first screening tool to assess the risk of conditions such as heart disease, diabetes and high blood pressure. Although it is not a clinical tool, it provides a quick observation of whether your weight is within a healthy area.
How to Calculate Your BMI: A Simple Guide
There are 2 Ways to Calculate BMI:
-
Metric System:
BMI = weight (kg) / height (square)
Example:
If you weigh 70 kg and are 1.75 meters long:
BMI = 70 / (1.75 × 1.75) = 22.86
-
Imperial System:
BMI = (weight in LBS / Height in inches) × 703
Example:
If you weigh 154 pounds and are 69 inches long:
BMI = (154/4761) × 703 = 22.75

Understanding BMI Categories
According to the World Health Organization (WHO), BMI comes in the following categories:
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5–24.9 | Normal Weight |
| 25–29.9 | Overweight |
| 30 and above | Obese |
These series help identify health risks and determine appropriate nutrition or exercise plans.
BMI vs. Body Fat Percentage: What Is More Accurate?
While BMI gives a common sign of body weight in relation to height, it does not measure the body’s structure – especially how much your weight is of fat vs. muscle.
For Example:
- A muscle athlete may have high BMI, but body fat can subside.
- An motionless person with low muscles can have a normal BMI, but high body fat.
Body fat gives a clear picture of percentage fitness. Use BMI as an initial point, but mix it with another matrix as:
- Waist hip conditions
- Body fat % using brakes or Dexa scans
- Lean mass vs fat mass analysis
How Right is BMI for Indians?
In India, health experts often use a modified BMI scale, as Indians develop metabolic conditions such as diabetes at BMI levels. Here is the adjusted version:
| BMI Range | Indian Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5–22.9 | Normal |
| 23–24.9 | Overweight (at risk) |
| 25+ | Obese |
So, if you’re in India, it’s recommended to use country-specific guidelines for better accuracy.
History and Science Behind BMI
The BMI formula was created by Belgian mathematician Adolf Quetlets in the 1830s -not as a health tool, but as a way of analyzing population figures. It was not until the 1970s that the medical society began to use it to classify body weight and assess the risk of the disease. Although the old one in some ways remains a useful starting point in public health due to its simplicity and speed.
When to Use BMI
