FAQ
What is a healthy BMI?
For adults, the WHO defines 18.5–24.9 as healthy weight, 25–29.9 as overweight and 30+ as obesity. BMI does not distinguish muscle from fat.
Is BMI accurate for athletes?
Not always — muscular people can have a high BMI with low body fat. Waist size or body-fat estimates add context.
