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

This can be stated in equational form as [pi](4321)/[pi](4312) = [pi](3421)/[pi](3412), which is true since [pi](4321) = 1/96, [pi](4312) = [pi](3421) = 3/96, and [pi](3412) = 9/96 (as a simple computation yields).
