Frequently Asked Questions (FAQ)
How is Body Mass Index (BMI) calculated?
Body Mass Index is calculated using your weight and height. In the metric system, the formula is: weight (kg) divided by height squared (m²). In the imperial system, the formula is: weight (lbs) divided by height squared (inches²) multiplied by a conversion factor of 703.
What are the different BMI categories according to the WHO?
According to the World Health Organization (WHO), the standard adult BMI classifications are: Underweight (BMI below 18.5), Normal Weight (BMI between 18.5 and 24.9), Overweight (BMI between 25.0 and 29.9), and Obese (BMI of 30.0 or greater).
Is the BMI calculator accurate for athletes and bodybuilders?
BMI is a general estimation tool and does not distinguish between muscle weight and body fat weight. Because muscle is denser than fat, muscular athletes, weightlifters, or bodybuilders may register as "overweight" or "obese" despite having very low body fat percentages.
How can I lower my BMI score safely?
To lower your BMI score safely, you should aim to reduce your overall body weight by combining a balanced, calorie-controlled diet rich in whole foods with regular cardiovascular and strength exercises. Always consult a certified healthcare practitioner before embarking on major weight loss regimens.
