What is BMI?

Body Mass Index (BMI) is a standardized measure that helps determine whether an individual has a healthy body weight relative to their height. It is widely used by health professionals as an initial screening tool to assess weight status, categorize health risks, and recommend lifestyle changes.

The BMI formula is:BMI=Weight in kilograms(Height in meters)2BMI = \frac{\text{Weight in kilograms}}{(\text{Height in meters})^2}BMI=(Height in meters)2Weight in kilograms​

BMI categories, according to NHS and WHO guidelines, are:

  • Underweight: BMI less than 18.5
  • Normal weight: BMI between 18.5 – 24.9
  • Overweight: BMI between 25 – 29.9
  • Obese: BMI 30 or higher

Understanding your BMI can help identify potential health risks such as cardiovascular diseases, diabetes, and joint problems.

Example BMI Calculation

Let’s see an example:

  • Weight: 70 kg
  • Height: 175 cm

Step 1: Convert height to meters:175 cm÷100=1.75 m175 \text{ cm} ÷ 100 = 1.75 \text{ m}175 cm÷100=1.75 m

Step 2: Calculate BMI:BMI=70÷(1.75×1.75)=22.86BMI = 70 ÷ (1.75 × 1.75) = 22.86BMI=70÷(1.75×1.75)=22.86

Step 3: Determine BMI Category:
Since 22.86 falls between 18.5 and 24.9, the BMI category is Normal weight.

This shows that the individual’s weight is within a healthy range according to NHS standards.
