There are formulas out there that provide body fat estimates: http://www.healthstatus.com/calculate/bfb
You can compare you BMI with this. It seems pretty accurate - I have had test with calipers and compared it to the results of the formula. The YMCA formula is lower that the navy formula. BMI should not be used with certain athletes (notably weight lifters). Cheri ********************** Cheri A. Budzynski, Ph.D. Assistant Professor of Psychology Heidelberg College 310. E.

Actually, weight is determined in part by the force of gravity pulling on an object's mass. The force of gravity lessens the further the object is moved away from the center of a rotating objects. That's why things are "weightless" in space. They still have mass, but without the pull of gravity, there is no weight. So, technically speaking, when we diet we are trying to loose body mass, not by changing our height but by changing other body dimensions (ie, our waist line).
