Patient discussion about equation

Q. how do i determine what is the right weight i need to be? i know there is a way to calculate it, an equation , what are the parameters in it ?

A. I don't mean to burst any bubbles, but BMI is definitely not a good way to determine what weight you should be. If you considered that a body builder or a professional athlete is considered obese under BMI standards then you would know what I mean. Here is an article about it I found on Medical News Today: http://www.medicalnewstoday.com/articles/49991.php
