Frequently Asked Questions

What is BMI?

BMI (Body Mass Index) is a common measure of whether your weight is healthy. It is calculated as: weight (kg) ÷ height² (m²). The WHO uses BMI as a key reference for assessing obesity levels.

What is the normal BMI range?

According to WHO standards, a healthy BMI range for adults is 18.5 - 24.9. Below 18.5 is underweight, 25.0 - 29.9 is overweigh, and 30.0 and above is obese.

What are the limitations of BMI?

BMI cannot distinguish between muscle and fat — muscular individuals may be misclassified. It also does not apply to pregnant women, children, or athletes. Consider combining it with body fat percentage and waist circumference.

How can I improve my BMI?

The key is calorie balance: a deficit for weight loss (burn more than you consume), or a surplus for weight gain. Aim for 150 minutes of moderate exercise per week, along with a balanced diet and adequate sleep.
