FAQs

What is a healthy BMI?

For adults, WHO considers 18.5–24.9 healthy. Some Indian health guidelines use lower cut-offs, such as 23 for overweight.

How is BMI calculated?

BMI = weight in kg ÷ (height in metres)².

Is BMI accurate for everyone?

No. BMI does not separate muscle from fat, so athletes, older adults and pregnant women should use other measures too.
