New BMI

It boosted me from 24.8 standard to 25.5 new at 5'3". I'm ultimately shooting for mid-range anyway so it won't make much of a difference at that point.0

I'd like to see how it correlates to health outcomes before passing judgement. It drops me .3 which is nice, but I'm skeptical, particularly since it doesn't differentiate between men and women, who have different sized bones.0

I'm tall as heck. (6 ft)
Current Weight- Standard: 23.0 New: 22.1 (Difference: 0.9)
Goal Weight- Standard: 19.7 New: 18.9 (Difference: 0.8)

when I go off just height and weight it says Im like 50% but at the gym my trainers tell me Im 41% I can never trust these calculators.0

You're right - 18.5 is 102 lbs. On the old chart my lowest healthy weight is 105 lbs.1 -
This one added 1.3 to my BMI which means I could go down to 87 pounds and still be a healthy weight. No way would I look healthy at that weight when 100 pounds has me on the skinny looking side of healthy already.0

As if my body dysmorphia wasn't pinging enough, my BMI went up a full 2 pts and now it says 101 to 137 lbs. 137 lbs is struggle weight. Shoot I'm struggling now!3

5’4”... increased mine & went from overweight (old) to morbidly obese (new). I call bs1

I also don't like the BMI. I've always had a large frame. My childhood doctor told me to measure my waist and keep it below 35inches. New BMI is 0.7 more than the standard. Morbidly obese either way.0

Seems like the "new" BMI calculators just fudge with the margins between categories but by-and-large most ratings are unaffected.
The number in itself really doesn't matter. What matters is whether you are healthy or not. It has been well documented that people who are obese tend to have more health problems than those that don't.
Problems often associated obesity include (but are not limited to) diabetes, high blood pressure and coronary heart disease. There is no doubt that if you lose weight, you also reduce your risk for these and other potential health problems.
If your BMI rating is in the over-weight or obese categories, it's a warning that you are at risk for these and other health problems and that you should take steps to assess and address any such problems that exist.
Then again, just because your BMI rating is in the "healthy" category doesn't mean that you still aren't at risk for the same problems and, if you have a family history of such problems, it's also wise to take the steps to assess and address any such problems that may exist despite your "healthy" BMI rating.
It really is just a number after all.2 -
Oh, I know. It's probably similar psychology to the difference between weighing 200 lbs and 199 is the same as 202 and 201. But somehow, it feels more significant. I've gone from Class III obesity (45 BMI) to overweight (29.9) in eleven months. To then be shoved back over the line into Class I obesity by the new scale is annoying. Even though it's about a .8 difference. Like if this had been posted while I was still in obesity or if I were down to 29.1, it wouldn't bug me. But because it puts me into a different category, it bugs me.
Ah well. My goal weight is healthy by both calculations.1 -
Here is a link to some explanation behind the new formula:
https://people.maths.ox.ac.uk/trefethen/bmi.html
Basically, it was a mathematician who argued that people don't "scale" up in a linear fashion. He believes that BMI is just a number- but maybe this formula is more accurate.
I agree with many posters on MFP who share that BMI is more of a number to look at the general population- and that we shouldn't get too hung up on it. (I just recently learned that until 1988, the overweight category started at 27. Then they lowered it to 24.9)
However, I have found that my maintenance weight seems to put me around 25.4/25.6 on the old BMI scale, puts me at 24.8 on the new scale- and like the poster above- where there really is no difference between 201 and 202 vs 199 and 200- I do take some pleasure in being "normal".0 -

It puts me at a healthy BMI (18.8) where old BMI makes me underweight (18.1).
My doctor told me I'm super healthy, so I'm going to definitely side with new BMI.1 -
Mine is 0.7 more on the new.0
