Check your Body Mass Index (BMI). If it is below 20 you do not need to lose weight. If it is above 26, you possibly do.
Although weight alone is a fair indicator as to whether a person is over weight it is more accurate to use their BMI. This describes body weight relative to height and is strongly correlated with how much body mass (including fat) a person has:
Weight (kg) / height (m)2 = BMI
(Weight (Ibs) / height (in)2) X 703 = BMI
Meaning of the BMI value:
Below 20 Underweight, 20 -
