a BMI is a Body Mass Index. its a calculation that takes into account how tall you are vs how much you weigh and spits out a number. you can read more about it here

never heard any. WDYM?

http://www.npr.org/templates/story/story.php?storyId=106268439

this is my primary reason for not putting much stock in it.

3. It is physiologically wrong.

It makes no allowance for the relative proportions of bone, muscle and fat in the body. But bone is denser than muscle and twice as dense as fat, so a person with strong bones, good muscle tone and low fat will have a high BMI. Thus, athletes and fit, health-conscious movie stars who work out a lot tend to find themselves classified as overweight or even obese.

sweetheart if you're an athlete with a high BMI then you're in the wrong thread :) the BMI is super helpful for someone like me that's just plain fat

sorry to disappoint, but its not just athletes that have that issue.

as an aside I go running/play ball a couple times a week and I still have some weight to lose (after my recent 25lb drop). My BMI (as does everyones) drops when they lose weight, its just an issue of basing your ideal body on that. even you stbaum may find as you get to your ideal looking body that the BMI is still very high, or it could be perfect and you could still have more fat on you to lose. either way nothing wrong with it if you like watching the number go down, just don't put too much stock in the "ideal"

I don't think that if I'm a 5'10" male and weigh 180 I'm fat, yet according to the CDC if my BMI is over 24.9 (in this case it's 25.8) then I'm overweight!

Quote from: http://www.cdc.gov/healthyweight/assessing/bmi/adult_bmi/english_bmi_calculator/bmi_calculator.html
For your height, a normal weight range would be from 129 to 174 pounds.
That's just plain crazy IMHO. A 129 pound adult male would look very scary!!!

I agree that BMI is really an outdated form of fat calculation. Best way to calculate body fat % is through an MRI. But I'm not about to do that.

Which brings me back to my question



Ok now I'm confused. If the ideal is 20/25 why would someone that is already at 21/22 not going to win? I'm missing something.

measured as a percentage of the excess of starting weight over the amount the same individual would need to weight to achieve a BMI of 20 or 25 for women

Am I the only one here who has no clue what that means?

Maybe someone can provide an example?

Thinking of doing a simple low calorie diet? Might not be the smartest way to do it.

If somebody is 6ft tall and weighs 220 then to get to a BMI of 25 he'd need to lose around 40lbs. Whatever % of 40lbs he loses is his fat % loss

Kekwik and Pawan's study proves that calories from different sources affect the body differently. So it's the source and type of calorie that makes the difference as opposed to the amount. And if you will allot all of your limited calories to carbs you may even end up gaining weight.

This is crazy, no way am I going down to 180! Don't want to look like my grandfather after the concentration camps. This might be a push to see that you're overweight and need to lose some pounds, but nothing more.
