What is BMI?
BMI (Body Mass Index) is a standard formula used by health professionals to assess whether a person’s weight is appropriate for their height. It’s calculated by dividing your weight in kilograms by your height in meters squared.
Formula:
BMI = weight (kg) / height (m²)
Although BMI does not measure body fat directly, it is widely used as a quick and reliable method to categorize individuals into different weight ranges.

BMI Categories
The World Health Organization (WHO) defines BMI ranges as follows:
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5 – 24.9
- Overweight: BMI 25 – 29.9
- Obese: BMI 30 or higher
These categories are guidelines and may vary slightly depending on age, gender, and muscle mass. For example, athletes may have a higher BMI due to increased muscle, even if their body fat percentage is low.

Limitations of BMI
While BMI is a great starting point, it does have some limitations:
- It does not differentiate between muscle and fat mass.
- It may not be accurate for athletes, bodybuilders, or elderly individuals.
- It does not consider body fat distribution.
For a more complete assessment, BMI should be used along with other health indicators such as waist circumference, body fat percentage, and lifestyle factors.

If your BMI falls outside the normal range, don’t worry. Small lifestyle changes can make a big difference. Here are some tips:
- Eat a balanced diet rich in vegetables, fruits, and whole grains.
