It is a way to know whether your weight is appropriate to your height. It is your weight in kilograms divided by height in meters squared. BMI = weight (kg) / height squared (m).
How can the BMI be calculated?
Example: If your weight is 70 kg and height is 160 cm, the height will be converted from cm into meter by dividing it by 100, multiply the result by itself and then divide by the height squared. 70/2.56 =27 (compare the result with the table below). You can multiply the height squared (2.56) by 20 to 24 in order to know the best weight.
BMI can be applied to adults only and not to the kids or teenagers, in the growth age. It also cannot be applied to athletes, pregnant, breastfeeding women, and elderly people.
After calculating the BMI, you can compare the result with the table below. Generally, those whose BMI increases, the potential risks of suffering from critical serious diseases increase. However, those whose BMI is normal, the risks will be less as long as they are not smoking or practicing sports regularly or not eating fats or sugars too much.
