Frequently Asked Questions

What is a healthy BMI range?▼
A BMI between 18.5 and 24.9 is considered healthy for most adults. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or above is obese.
Is BMI accurate for athletes?▼
BMI does not distinguish muscle from fat, so very muscular individuals may register as overweight despite low body fat. Use body-fat percentage for a fuller picture.
