What is BMI (Body Mass Index)?

BMI stands for Body Mass Index, a numerical value calculated from your weight and height. It is a standard measurement used to classify individuals into different weight categories.

The formula used is:

BMI = Weight (kg) ÷ Height (m²)

Based on the result, your body is categorized into:

  • Underweight (BMI < 18.5)
  • Normal weight (BMI 18.5 – 24.9)
  • Overweight (BMI 25 – 29.9)
  • Obese (BMI 30 or higher)

Although BMI does not directly measure body fat, it is a reliable indicator for most people and widely used in medical assessments.

Example of BMI Calculation

Let’s understand how the BMI calculator works with a real-life example:

Example 1:

  • Weight: 70 kg
  • Height: 170 cm

Step-by-step calculation:

  • Height in meters = 1.70 m
  • BMI = 70 ÷ (1.70 × 1.70)
  • BMI = 24.22

Result:

  • BMI Value: 24.22
  • Status: Normal weight

This means the person has a healthy body weight according to standard BMI classification.

BMI Categories Explained in Detail

Understanding your BMI result is important. Here’s a breakdown of each category:

Underweight (BMI < 18.5)

If your BMI is below 18.5, you may be underweight. This could indicate insufficient nutrition or health issues. Increasing calorie intake and following a balanced diet may help.

Normal Weight (BMI 18.5 – 24.9)

This is the ideal and healthy range. It means your weight is appropriate for your height, and your risk of health problems is lower.

Overweight (BMI 25 – 29.9)

Being overweight may increase the risk of conditions like heart disease, diabetes, and high blood pressure. Lifestyle changes can help bring BMI back to normal.

Obese (BMI 30 and above)

Obesity indicates excessive body fat, which can lead to serious health complications. Medical guidance, exercise, and diet control are recommended.

Checking your BMI once is helpful, but monitoring it regularly is even more important. Here’s why:
