Question 1

What is a healthy BMI range?

Accepted Answer

According to WHO guidelines, a BMI between 18.5 and 24.9 is considered healthy for adults. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or above is considered obese. For Asians (including Indians), a lower threshold of 23-27.5 is sometimes recommended.

Question 2

How is BMI calculated?

Accepted Answer

BMI is calculated as weight (kg) divided by height (m) squared. Formula: BMI = weight(kg) / height(m)². For example, a person weighing 70kg who is 1.75m tall has a BMI of 70 / (1.75 × 1.75) = 22.9.

Question 3

Is BMI accurate for everyone?

Accepted Answer

BMI is a useful screening tool but has limitations. It doesn't account for muscle mass, bone density, age, sex, or where fat is distributed. Athletes may have a high BMI due to muscle. It should be used along with other health assessments for a complete picture.
