Are You Overweight?

Obesity is recognised by the World Health Organisation as a 'worldwide epidemic'.

Are you overweight? As we are all different shapes and sizes, there is not one recommended weight for your height.Instead there are a range of weight that are healthy for yout height.

Previously, we usually measure our average appropriate weight using :

Appropriate Weight = Height - 100(for man) or Height - 110( for woman)

But, it is not too suitable using for people under 140 or lower. There is other way to check your ratio of weight to height, known as your BMI ( Body Mass Index ).

BMI = Weight / (Height * Height)
Where the weight is in Kilogram, and height in Meters.
Note :
- it design only for man and woman over than 18 years old.
- Suitable for Asian, and Caucasian


BMI result :
>> less than 18.5 = underweight
>> 18.5 to 24.9 = normal
>> 25 to 29.9 = overweight
>> 30 to 40 = obese

Here is the example :
My weight : 54.5 kg
My height : 168 cm = 1.68m

BMI = 54.5 / (1.68*1.68) = 54.5 / 2.8224 = 19.31
It's mean i am normal

Then how about you ??
