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.

BMI is a quick screening measure, not a diagnosis. It does not distinguish muscle from fat, so it can overestimate fat in athletes and underestimate it in older adults. Waist size and other checks give a fuller picture.
