muscle doesn't weigh very much more than fat.
0.16 grams more per kg i believe.

i'm only 10.6 arg my docter keeps giving me all greasy stuffs to eat but i don't eat greasy tthings cause i think they're too yucky and i'm vegetarian, so I'm probably going to be the skinniest person you'll ever meet. (i'm 16 and i weigh only 95lb ^_^') but i can wear anything, so yay for me! ^_^(yea i know, this is off topic)

My BMI is like 100. :sarcasm:

Not only does BMI not take in account muscle, it also does not quite take in account stuff like breast size. Is it strange that of two people with the same length but say, three cup-sizes difference, the one with the bigger breasts weighs a bit more?

Also, it depends on the kind of build someone has. It takes in account length, yes, but not necessary the bone structure. If I'd look at my sis's BMI, she would be obese or almost obese. However, although she has a few kilos overweight, if she'd weigh the weight BMI suggests she should, it would be very unhealthy for her. Even our doctor said so.

There are more variables in human build than just length and weight.

My BMI is 22.4, or so it was last time I checked.

The (Lack of) Science behind the BMI

I can't believe I read this. Normally, I hate numbers. XD But basically, it says that the BMI cannot be held to much value due to two major reasons. One being that the basis on the average appropriate weights were based off of british and scottish soldiers from 200 years ago, and that the mathematical formula is a bit off. This results in weights being given that are not proportionate to the height of the individual.

That said, I can understand that using the BMI in a casual sort of way can be helpful..to a degree. I try to take everything with a grain of salt, just due to human error. Scales can be calibrated differently, so when I weight myself I usually take a sort of average or in between of two to three scales. Key being "when" I weigh myself. I don't think we have a single scale in this house. haha I usually just go by how I feel in my body. Then I exercise, and when I get an opportunity to weigh myself, I do a kind of "check in" to see if what I see on the scale is on par with where I believe myself to be. Same with the BMI. I usually give it a bit of a buffer by adding 5-10 pounds to the "ideal" weight it gives me. It's a bit more reasonable. I, personally, would not like to look like the walking dead (not in offense to skinny people; naturally skinny people usually look good in their bodies. I, however, would look ridiculous if I were that skinny due to my body structure). XD

I don't that you have to know my BMI. It is private. I'm sorry but not telling.

@ happy star - thank you for posting the article... my brain did spaz out a little reading it but it was informative! ^^
BMI is another another number that makes people feel shitty about themselves! as if weighing yourself isn't bad enough.
the OP is seems focused on topics that are weight related and shallow, just saying. >_>

notice how the only people complaining about the system are the people who are looking for flaws to ignore the fact that they are overweight/borderline overweight

Ouch dude.
But seriously, according to the BMI scale I'm underweight. And I know for a fact that I'm most definitely not.

I'm sure if anybody here has a weight problem, then evidently they already know that they do and they certainly wouldn't need a calculator to tell them that. However, this system does have flaws. While there may be some truth to it, and maybe it would be useful as a guideline, it's certainly nothing to base your overall health on.

20.4 BMI. It really depends on the day and time of the month, meaning it dips into the nineteen area a bit and might go up to 21.0 or such at various points. Presently I weigh around 130, and I'm twenty. When I was seventeen I was pushing 200. My methods were in no way healthy -- although going vegan probably didn't hurt anything -- but for all my present-day issues, at least I'm not nearly as big as I was.

clearly there are more things to look at to determine whether or not a person is healthy, i never claimed for this to be the best method of determining health. a quick look at the other weight topics that i am going to assume were sparked by this thread, are people admitting they are overweight and people rushing to reassure them that they should just be content and love themselves for who they are.

if the people recognize they have a problem, they shouldn't be told to just simply be content with their current state and not attempt to change it. if anything that would discourage them from becoming healthier, and one can only assume these people saying these things feel the same towards themselves and therefor don't make the effort to be healthier either.

But being overweight or heavier doesn't necessarily mean you have a problem...besides aesthetic reasons I guess.

being overweight is linked with many health problems.

okay, none of that changes the fact that it's still unhealthy to be overweight?

if you already have a family history of heart disease, being overweight is going to increase that risk. i can't believe people are actually trying to say it isn't unhealthy to be overweight lmao

that and i've met very few people who are overweight that are genuinely happy with their appearance. it's easy to say that you are, but at the end of the day it's pretty easy to tell who the people are that just keep telling themselves things over and over again that they don't truly believe. it's beyond the physical harm it can cause a person, it comes with a lot of emotional problems as well.

Because sometimes, it's really not 'unhealthy' to be heavier or to be overweight.
It would make no sense to tell a person who exercises for at least an hour a day, and who has a balanced and proportioned diet that they're still 'unhealthy' because they weigh a few pounds more than someone else. That's absurd.

And yes, there are plenty of people are in denial. However, there are also people who are sincerely content with how they look, and surprisingly, they're not always the people with the average bodies and common looks.

Dear, overweight is, according to BMI, even if I have to believe it, 25 and up. As I said in the post I quote part of below:
During my check, I found out it's currently actually 22.3. To become overweight according to BMI, I'd need to gain 20 lbs. Wouldn't call that borderline overweight, let alone overweight.

So sorry to break it to you, but I am not 'looking for flaws to ignore the fact that I am overweight/borderline overweight'. I am merely pointing out its flaws for the sake of showing the system is not perfect. Not so that I can ignore anything.

18.9 It say's I'm normal, but I think I need more weight on me. 117 is tiny to me.
Also. Muscle does weigh more than fat, just putting that out there.

assuming a good percentage of the website is from america, the "common appearance" isn't a healthy one. being overweight is still a health concern.

18.3...

Apparently I am underweight.

odd? I am perfect! ;)

I'm fatter then holy hell, and I don't see a problem with the BMI. I'm not gonna make up excuses.. I'm just shove my face too much with carbs lol
Of course I excersize, however that doesn't make up for my obsession over oatmeal/things high in carbs and gross. I love it too much :rofl:
I'm a fatass, but I'm totally content with how I look and, as far as I know, I don't have any health problems since I do my best to hit the treadmill 3+ times a week.

And honestly, my curves make me feel beautiful <3
