What's your BRI?

[Dressedilemma]

Well, not really asking you to post numbers, but I've just read an article about how BRI is a better indicator for health than your BMI. https://bri-calculator.com/

If you look at the healthy/unhealthy categories, do yours match up?

My BRI is 'very lean' while my BMI is within normal weight category. My BRI suggests that I need to check my diet to ensure I'm not missing out on nutrients (I eat really well) and also suggests I should do some weight training (I walk and do reformer Pilates regularly each week). I'm really not sure how to take the BRI, it seems a little 'dramatic' to me.

Yes. Which isn’t surprising, I’m athletic so have very low body fat overall and have always tended towards being more of a pear than an apple shape anyway.

I think BRI is a better measure because it does hone in on where weight is carried and acknowledge that fat carried around your middle is a particular risk. But tbh I suspect that many of the same people who are a bit in denial about their weight and struggle with accepting BMI as a broad measure of whether they’re a healthy weight will dislike BRI even more: all the claims like “even professional rugby players would be classed as obese so I think my BMI saying I’m obese is a load of rubbish” are even less possible to hide behind in a model which focuses on body fat.

I’d never heard of this , I’ve come out as very lean although my BMI is at the top of the normal range

Lean, although my BMI means I'm obese

My BRI also says very lean, but I am not, I’m just above a healthy BMI and could lose 2 stone before I would look “very lean”.

I just did it. I am absolutely not 'very lean' though it says I am. My BmI is overweight. I just happen to have a small-ish waist, and fat limbs.

3.94 Your BRI suggests a lean to average body shape, with a waist size smaller than most people.

BMI is over 29.

Lean to average with a bmi of 24. Something

I feel that bmi, with all its faults, feels more accurate but then, I'm comfortable with hard facts about my weight I suppose!

As the creator of https://bri-calculator.com/ , I appreciate you sharing our website! It's great to see discussions about BRI as a health indicator.

While BRI can be more accurate than BMI in some aspects, particularly in considering body shape, it's important to view it as just one part of overall health assessment.

For those interested in learning more about BRI vs BMI or interpreting results, feel free to explore our site. We always welcome feedback to improve our tool.

Thank you for bringing this up and sparking the conversation!

Very lean on BRI 2.84

Normal weight on BMI 23.3

I’m a pear/hourglass and carry all my weight on arms bum and legs, so not a surprise

@Yuxiang I suggest you adapt your tool so that it doesn’t tell all people with a very lean BRI that they have health risks eg missing nutrients. If they have a normal BMI and a lean or very lean BRI the chances are they are simply hourglass or pear shaped and not undernourished at all. Health conclusions need to follow consideration of both metrics.

Very lean BRI, almost obese BMI

Hi minipie, @minipie

Thank you for your insightful feedback. You've raised an excellent point about the potential discrepancy between BRI and BMI results, especially for pear or hourglass body shapes.

We agree that health conclusions should consider multiple metrics. We'll work on updating our tool to provide more accurate health advice based on both BRI and BMI.

Your input is invaluable in helping us improve our service. We'll keep you updated on the changes we implement based on your suggestion.

Best regards,

My BRI is 4.09 "lean to average", which amazes me as my waist is shamefully more than half my height.
My BMI is 23.4, the top end of "normal".

I'm post menopausal. My tummy grew at a rate of knots during menopause, and has stayed the same size despite losing around 7kg since then. This indicates visceral fat; I don't think your tool should have placed me in a lean category.

It's a great idea, though, @Yuxiang!
Further comment: I didn't see measuring instructions so I took the relaxed (larger) circumference, as advised by the NHS.

There's another one that includes hip measurement, which I think counters those of us with big bums but teeny tiny waists

Ooh, interesting, @Sparklfairy!

Mine seems more credible on this calculator:
Percent Body Fat: 40.1%
Visceral Adipose Tissue (VAT): 3.4%
Total VAT Mass: 2.4 kgs
Body Roundness Index: 4.0 (out of healthy zone)
Body Mass Index (BMI): 23.4

It gave almost the same BRI as the first one but, this time, it says it's too high. I think that's right: my waist/hip is 0.9, while WebMD says it should be under 0.85.

I know we need some visceral fat, but I'm not enjoying the image of 2.4kg of lard on my internal organs 😬

This seems slightly better than the BMI measurements which have been found countless times to be racist and inaccurate for black, Latina and indigenous women who naturally tend to have a more muscular body tone and carry weight on hips rather than stomach, which is less risk.

according to my BMI I’m well into the obese range. I can’t do BRI yet as don’t have anything to measure my circumference. However I wear a size 10 top 12 bottom, and my stomach is flat. But I’m black, and I’ve also been told I have a heavier bone and muscle density which neither of these tools consider.

@Garlictest Thank For your advice！ I Would add measuring instructions on website this weekend. It is important to get a right circumference

How interesting, I’d never heard of this before!

The first one gave me a score of 2.32, Very Lean, which I found weird as my BMI is 22 and I’m a size 10 - so slim but hardly lean, I’d say. The second one including hip measurements came out as 2.2, in the “healthy zone.”

I’m an inverted triangle shape, so I do have a waist, but comparatively narrow hips. My shoulders are the widest part of my body.

BRI is pretty kind isn’t it! It says I’m very lean where as my BMI is 21.5. I’m a size 10.

In BRi I then played around and added 5 lbs and 2 inches to my waist which I have been before and was not looking healthy slim at that time, even with those inflated calculations BRI still said very lean. To get out of BRI “very lean” category I reckon I’d have to be a size 14.

@Garlictest Hello, we update the website to add waist measurement instructions for you ! go to check it https://bri-calculator.com/

Thanks for your advice, have a good day!

I'm not sure about this. I do have a pretty small waist but I have broad shoulders, big boobs, fairly broad hips, and I'm not particularly bony. I really don't think I'm unhealthily thin.

I have been unhealthily thin at one point due to health problems. I was a good 8 or 9kg thinner then. That's when I started getting vitamin deficiencies.

You can't tell all this just from someone's waist!

My bri and bmi same as you!
As with most of these things, they provide some parameters, but looking in a mirror, or finding it's easier/harder to do up a waistband is more realistic!
