If you're 205 cm tall, how much should you weigh?

After many years of weighing about 250 pounds, I recently decided to lose some weight. It was a lot easier than I thought, and now I'm down to 215 pounds. But I don't really know if I was overweight before or not, and I don't know if I'm underweight now.

	250 lbs	215 lbs
BMI	27 (overweight)	23.2 (normal)
Tall BMI	26.1 (overweight)	22.4 (normal)
Dr. Koop	Ideal (232-255)	Underweight
People's Choice	Overweight	Ideal
Devine Ideal Weight	Overweight	Ideal

So clearly, everybody except Dr. Koop (a bit of a pudge himself) thinks I was overweight at 250, and pretty much at a good weight at 215.
