BMI categories for adults (WHO)

  • Under 18.5: underweight
  • 18.5–24.9: healthy weight
  • 25–29.9: overweight
  • 30 or more: obesity (class I 30–34.9, II 35–39.9, III 40+)

For people of Asian descent, health risks rise at lower BMIs, and 23 and 27.5 are often used as action points. BMI does not separate muscle from fat, so very muscular people can have a high BMI without excess fat. It is a screening tool; talk to a health professional about your own situation.
