FAQ
What is BMI?
Body Mass Index (BMI) is a value derived from a person's weight and height. It is a widely used screening tool for weight categories, but it does not directly measure body fat or overall health.
What are the standard BMI categories?
The standard ranges are: Under 18.5 = Underweight, 18.5–24.9 = Normal weight, 25–29.9 = Overweight, 30 and above = Obese. These are general guidelines and may not apply equally to all individuals.
Is BMI an accurate health indicator?
BMI is a general screening tool and has limitations. It does not account for age, sex, muscle mass, bone density, or distribution of fat. Consult a healthcare provider for a comprehensive health assessment.
