How to if you are underweight?
Everyone I meet tells me that I am underweight, of course it is not a rocket science, I can look myself in mirror and tell that I am underweight. But I never understood, what is the normal weight? If I start working on my weight how will I come to know that I am not underweight anymore. So I consult the doctor not only to know how to gain weight but also to know what is the norms of weights for human beings.
So I came to know about the “body mass index” (BMI) which is a statistical measure of the weight of a person scaled according to height. BMI is calculated as the individual's body weight divided by the square of their height. In normal words it means what your should be as per your height. And it can be calculate by everyone. Just put your weight and height in following formula and then compare the answer with the “Body Mass Index” table.
BMI = Weight (kg)/Height(m2)
If your answer is,
Less than 16.5 ---- severely underweight
16.5 to 18.5 ---- underweight
18.5 to 25 ----- normal
BMI is frequently used to assess how much an individual's body weight departs from what is normal or desirable for a person of his or her height.
So just calculate your BMI and find out if you are underweight or not, I found out I am underweight and I am working on it now.
