Why is the BMI important?

What is the purpose and importance of BMI?
Your BMI is a measurement that is a ratio of your weight and height. Its a good way to gauge whether your weight is in healthy proportion to your height. In fact, knowing your BMI can help you – and your GP – determine any health risks you may face if its outside of the healthy range.
Why BMI is a bad indicator?
One of the main issues with BMI is that it cannot account for the difference between muscle and fat. Because muscle tissue is more dense than fat, many athletes and bodybuilders are considered overweight according to BMI despite being in peak athletic health.
What should your BMI be?
For most adults, an ideal BMI is in the 18.5 to 24.9 range. For children and young people aged 2 to 18, the BMI calculation takes into account age and gender as well as height and weight. If your BMI is: below 18.5 – youre in the underweight range.
