I'm confused as to why I get the same BMI, despite the fact that there should be a ten-pound difference between a female body, and a male body, according to this.

Well, I hope "lean body weight" isn't included in the range, because I think a 5'7" female who weighed 95 pounds would be considered near death. ;)

But the ideal body weight, yeah, that's what I'm supposed to weigh. Except this online thing doesn't factor in body structure. And I have a very slim frame, so if I weighed 136 lbs, I'd be very overweight.

haha.. that is true, isn't it :)

about the body structure.. it does seem to be an oversimplified thing.. like so many things on the internet.. but it did look like fun.
I don't think I'd want to put my stats in, though :P at least not until I'm fairly done losing weight :))
