Frequently Asked Questions
What is BMI and how is it calculated?
BMI (Body Mass Index) is a simple calculation using a person's height and weight. The formula is: BMI = weight (kg) / [height (m)]². For imperial measurements, it's calculated as: BMI = 703 × weight (lb) / [height (in)]². A BMI of 18.5-24.9 is considered healthy, 25-29.9 is overweight, and 30+ is obese.
Is BMI an accurate measure of health?
BMI is a useful screening tool but has limitations. It doesn't distinguish between muscle and fat, so athletes may have a high BMI despite being healthy. It also doesn't account for body composition, age, or ethnicity. BMI should be used as one indicator of health, not the only measure.
What are the BMI categories?
BMI categories are: Underweight (less than 18.5), Normal weight (18.5-24.9), Overweight (25-29.9), and Obese (30 and above). There's also a classification for severe obesity at 35-39.9 and morbid obesity at 40+.
Can children use this BMI calculator?
This calculator uses adult BMI categories and is not appropriate for children and teenagers. For individuals under 20, BMI percentiles based on age and gender are used instead. Consult a healthcare provider for proper assessment of children's weight status.
What should I do if my BMI is not in the healthy range?
A BMI outside the healthy range doesn't necessarily mean you need to lose or gain weight. Consider consulting with a healthcare professional who can assess your overall health, body composition, and recommend appropriate steps. Remember that health involves many factors including diet, exercise, sleep, and mental well-being.
