Frequently Asked Questions
What is BMI?
Body Mass Index (BMI) is a measure of body fat based on height and weight. It is calculated as weight in kilograms divided by height in meters squared. BMI is used as a general screening tool to identify potential weight categories.
What are the BMI categories?
BMI categories are: Underweight (below 18.5), Normal (18.5-24.9), Overweight (25-29.9), and Obese (30 and above). These categories are used to assess whether someone is at a healthy weight for their height.
Is BMI accurate for everyone?
BMI is a useful screening tool but has limitations. It does not account for muscle mass, bone density, or overall body composition. Athletes may have high BMI despite being fit. For personalized health assessments, consult a healthcare professional.
