Questions and answers

What is a healthy BMI?

For adults, the World Health Organization defines 18.5 to 24.9 as a healthy weight, 25 to 29.9 as overweight and 30 or more as obesity.

Is BMI accurate for everyone?

No. BMI doesn't tell muscle from fat, and it isn't meant for children, pregnancy or athletes. It's a general screening number only.
