We keep telling you to strive for a healthy weight through a clean diet and vigorous exercise. Then we tell you to maintain that weight if good health is one of your priorities. But what exactly is a healthy weight? It depends on each person, really, and while I'm not a doctor who can advise you about your magic numbers, I can lead you to this fun little calculator that will spit out some digits for you. All you need to do is enter your height and instantly, your healthy weight range will be calculated.

Let me warn you: Your range will come with a fairly big spread. Mine, for example is 118 pounds to 159 pounds. Since my scale currently reads 135 -- give or take a pound or two -- I figure I'm safe. And it seems I could drop a few or add a few and still be OK.

Now, if your weight right now is more than the upper limit or if you are unintentionally losing weight, please see your physician about possible health implications.
