Frequently Asked Questions

What is BMI?

BMI (Body Mass Index) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared.

What are the BMI categories?

BMI categories are: Underweight (BMI < 18.5), Normal weight (BMI 18.5-24.9), Overweight (BMI 25-29.9), and Obese (BMI ≥ 30). These ranges may vary slightly for different populations.

Is BMI accurate for everyone?

BMI is a useful screening tool but has limitations. It may not accurately reflect body fat in athletes (who have more muscle mass), pregnant women, the elderly, or people with certain medical conditions.

What should I do if my BMI is high?

If your BMI indicates overweight or obesity, consult with a healthcare provider for personalized advice. Focus on healthy eating, regular exercise, and lifestyle changes rather than quick fixes.

Can BMI be different for men and women?

The same BMI ranges apply to both men and women, but body composition differs. Women typically have more body fat than men at the same BMI, while men have more muscle mass.

How often should I check my BMI?

You can check your BMI whenever your weight or height changes significantly. For most adults, checking every few months is sufficient. Focus more on overall health habits than frequent BMI calculations.
