What is your BMI?

[superB]

Been a bit weight focused of late. Do you know your BMI (Body Mass Index)?

To calculate : http://www.health24.com/dietnfood/Weight_Centre/15-51-90.asp

I'm a 26 2 years ago I was at a 20

 

[orin76]

I've never scored well on BMI. Even when I was lean and mean (my rugby playing days), my BMI was always around 25 (overweight). I have short stocky build whereas BMI is geared towards the classic European build (slim & tall).

lemme show u why BMI is a load of crap.
I am a 26, and am now considered overweight according to this....
I however have a vo2 max of (edit: had 68, its actually 66...), I play a provincial sport and do some kind of a workout daily....

The reading is rubbish indicator of how much u should weight or physical health, i wouldnt give it a second thought

ROFL. BMI isn't "geared" towards anything. It is a ratio of your body weight to height.

BMI has nothing to do with vO2 max and it doesn't predict success in sports.


You guys seem a little touchy?

Mines is 18.2, has been for the last 15 years.

And what is that ratio supposed to tell you. According to BMI, if you're around 160cm tall and you weigh 70kg you're overweight. Depending on body structure this may or may not be true. That's what I meant when I said the test is geared towards a certain body type. Maybe I should say the test favours a certain body type.

Does this clarify things for you?

No it does not, however vo2 max is a very good indication of fitness levels. I was usign it to show how much BS the BMI calculation is. I never mentioned a relationship between the two?
Apparently i am over weight according to this calculation, and yet am very very fit playing sport at a high level?
I would need to lose 8 kgs to be a 24..... Let me just become malnourished...

Touchy? not at all, but some ppl might believe they are overweight when reading this calculation, when to be honest its BS...

 

[arf9999]

Mine's 24...

@Chiskop... seriously? 18.2?

The problem i have with this is.

My friend male is 1.75m he weighs 78 kg that is skinny but he registers over weight? He would be a skeleton if he goes down to 72 kg's

So you've been a manorexic for a long time then

It's a general measurement not scientific or specific and needs to be used in conjunction with other factors about each individual. As soon as people start doing lots of sport they should increase muscle mass. Muscle is heavier than fat so this immediately messes up the BMI readings.

So a high BMI on a person who does no exercise usually means they are over weight but as soon as the person is someone with an active lifestyle that needs to be accounted for.

Have you ever used one of those electronic scales that measure your BMI, water %, fat %, bone weight etc? They usually have 2 settings one for normal and one for active. Active means more than 10 hours of exercise per week. If you measure the same person on the two different settings the difference is incredible.

I find its a general useless measurement. I struggle to find ppl for whom this calculation actually works for. If it requires extra tweaking depending on your lifestyle etc it seems pretty pointless...Body fat % would be a better indication i think than BMI....

I am unsure as to how accurate the machines at the gym or the scales mentioned measure body fat %, but i am sure it is better than a BMI calculation.

 

[.Froot.]

Mine is 17....
My body fat percentage is somewhere between 2-4%.

Take your finger out off your mouth.........

Geez how many hours do you spend in the gym?

 

[superB]

Ok, in defense of those who have said BMI is useless, I may actually have to agree. Did a bit more research and apparently it really is quite subjective (when looked at in relation to body type, fitness levels etc etc). I also calculated my ex's BMI. He is the furthest thing from over weight and actually lands himself on the cusp of 'healthy' and 'overweight'.

Unfortunately in my case it is pretty accurate. The amount of weight gain in the lats few years is substantial enough to justify a 6 point leap on the BMI. *sigh*

It is scientific and it is specific, but it is not specific to fitness. All it is, is a ratio that can describe body type. Perhaps the confusion comes in with the term overweight - it doesn't mean obese, and it doesn't necessarily indicate unhealthiness.

(FWIW: my body fat is similar to froot's. It's all genetic. I haven't stepped into the gym this year and I'm certainly not fit atm. But enough about that, I'm off for a smoke.)

I tried the finger part after swallowing the wrong pill once... didn't work for me.
I'm just naturally well-built. Lean, but heavily-muscled. I usually spend about 12 hours a week training, but don't have a gym contract

 

[4cer]

well built ? oke you need your brain checked ....

Anything below 4.5% body fat is declared anorexic? so how are you well built? you can only be scrawny, and your muscles show cause you have no meat on you ?
