There is a saying among doctors that overweight issues are over-hyped and underweight issues are under-hyped. There are millions of underweight people on this planet who are desperately trying to gain some pounds. But, their plight is unheard and they are left to fight this battle on their own.
There is a common misconception that thin people are underweight. A person is underweight, if his/her body weight is too low to be healthy.
For knowing this you have to calculate your body mass index (BMI) by dividing your weight in kilograms with the square of your height in meters.
BMI = Weight (KG)/[Height(Meters)]^2
If your BMI is less than 18.5 then you are underweight. 18.5 to 25 is normal healthy weight and more than 25 is overweight.
