If you don’t know, here’s a link: BMI calculator
My BMI is 24.41, so according to this site I’m normal weight, but barely. I’m hoping to get that number to about 23 by the end of the year.
Note: A high BMI does not necisarily mean you’re overweight
So what’s your BMI?
Mine is 21.77, but it might be off by a little, because it wouldn’t let me say 6’0, so I had to say 6’1. 
I don’t trust those things 'cause see … It says I’m very obese, but muscle weighs more than fat, and I’ve got a lot of muscle especially in my legs. And, I’ve told certain people my weight, and they guessed way below - they couldn’t believe I was as much as I am.
I want to lose weight, but as long as I don’t get any bigger, I’m content. 
Keeping an eye on it, at least.
It says I’m at 23.29, but like FONY, it’s not a wholly accurate measure for me. As a swimmer and water polo player, I have a much higher muscle density than most people. I’ve always been fairly skinny, but just looking at my weight would make me seem kind of hefty.
24.5. I am aiming to lose weight though.
24.46, though that’s not really accurate- the big boobs sort of throw it off. 
I’m trying to lose weight, but I don’t think I look particularly fat so I don’t really care. A friend of mine is a very skinny so-and-so, but eats a ridiculous amount of junk food. She knows that she’s probably very unhealthy, but doesn’t appear to be so because of a high metabolism. Hence a good BMI doesn’t always mean you’re fit, and a bad BMI doesn’t always mean you’re going to suffer from illness and that sort of thing.
BMI-19.53
I do Wii Fit so i already knew that…
I’m right where i should be… 
22ish (not sure of my exact weight at this moment).
Wii Fit : 21.50 
I’m like 88% muscle so I’m good.
On Wii Fit it said my BMI was 19.4 but that thingamabob on the website said my BMI is 19.2. shrug But I bet if you tested my strength and everything, I’d be as weak as a kitten. And like lizardgirl said, you can eat a lot of junk food and not put on any weight and have a good BMI, but still be unhealthy. I eat a lot of junk food and don’t tend to put on any weight, but I bet I’ll be paying for it later on in life.
I also can’t believe “thingamabob” is a word in the Firefox dictionary.
I’m 17.68. According to the website, I’m underweight. Of course. I’d probably have a better BMI if I had more muscle. I’m probably 2% muscle, 3% fat, and the remainding 95% are my organs, skin (though technically an organ), hair, and bones. 
That’s me! Miss Skinny Mini!
It’s so awkward, when I’m eating something I enjoy, I can eat a lot, and gain probably .000001 lb. I’ve got a very metabolism. I get it from both parents.
Update…after the baseball season my BMI rose to 22.31!!
Wow…that was large…at least i’m still normal.
15.49. Is that bad?! I’m underweight… Stupid high metabolism. 
I’m only 82 lbs.
18.02. It has always been around there, so yeah.
BURN-E: Finally someone’s skinner than me!!! wishes I was on deviantArt so I could choose a dancing emoticon to use
Um, gee, uh, you’re welcome???
It’s just that I’m like the skinniest person in my class (maybe in the whole school) so it makes me feel a little happy that I’m not the skinniest for once. I wish that I could gain ten pounds. That’d make me happy.
Here’s an update: now I’m 23.57, so I’m feeling good about that.
