Frequently Asked Questions
What is a healthy BMI range?▼
A BMI of 18.5–24.9 is considered normal/healthy weight. Under 18.5 is underweight, 25–29.9 is overweight, and 30+ is obese. BMI is a screening tool — consult a doctor for personalized advice.
Is BMI accurate for athletes?▼
BMI doesn't distinguish muscle from fat. Muscular individuals may have a high BMI but low body fat. For athletes, body fat percentage is a better measure.
