What is a healthy BMI for a normal adult?
A . 16C32
B . 18C25
C . 14C27
D . 21C34

Answer: B

Explanation:

BMI (Body Mass Index) is calculated by dividing the body mass in kilograms by the body height in meters squared (there are many charts to save you having to make this calculation yourself). A BMI between 18 and 25 is considered healthy; anything under 18 is underweight, over 25 is overweight and over 30 is obese. Be aware that some people may fall outside the normal range and still be healthy, for example a power athlete carrying a lot of muscle may have a BMI over 25 and still be perfectly healthy.
