Goodbye BMI. Body Roundness Index doesn’t use weight and may become the new measurement.
BMI has had its detractors for a long time.

Since the 1980s, Body Mass Index (BMI) has been one of the most popular ways for healthcare workers to determine someone’s overall health, but it has plenty of detractors. The index has been called everything from inaccurate and misleading to racist, sexist and fatphobic.
Others find it useful as a quick and easy calculation for an overall health assessment. “Doctors have to take a bigger, broader picture,” Dr. Justin Ryder, associate professor of pediatrics and Northwestern University, told CNN. “They should look at their adult patient and not just say, ‘OK, your BMI is 31, you need to lose weight,’ as that’s not necessarily the answer all the time.”
However, this debate may be over soon after the development of the BRI, or Body Roundness index. Researchers say the index is a more accurate way to determine a person’s health because it emphasizes belly fat more and doesn’t require weighing the patient.
First, look at BMI and why some people have a problem with it.
What is Body Mass Index (BMI)
BMI was introduced in the early 19th century by Lambert Adolphe Jacques Quetelet, a Belgian mathematician who created the measurement to measure obesity for the government. The calculation is pretty simple: divide weight in pounds by height in inches squared and multiply by a conversion factor of 703.
The result puts people in one of 4 categories:
• Underweight – a BMI of less than 18.5
• Normal – a BMI between 18.5 and 24.9
• Overweight – a BMI between 25.0 and 29.9
• Obese – a BMI of 30 or above

The big critique of this measurement is that it doesn’t take muscle mass into consideration and muscles weigh more than fat. Therefore, a bodybuilder who is very lean can have a high BMI that incorrectly suggests they are overweight.
The measurement has also been called sexist because women tend to have more fat tissue than men. It’s also been accused of being racist because it was developed on Anglo-Saxon men and studies have found that people of various ethnic backgrounds are healthier at different BMIs.
Kimberlydawn Wisdom, MD, MS, FACEP, the Senior Vice President of Community Health & Equity for Henry Ford Health, says that BMI can also promote eating disorders and weight bias.
What is Body Roundness Index (BRI)
The BRI was first introduced in 2013, and it takes into account one’s height, waist circumference, and sometimes hip circumference for calculation. “It has to do with geometry. So if you look at Body Mass Index, you can come up with a geometrical explanation,” Diana M. Thomas, PhD, a Professor of Mathematics at the United States Military Academy at West Point and author of the first paper outlining the index, told Healthline. “With BMI you’re actually using just two measurements. You’re using weight and height. In the Body Roundness Index, we’re using a few more measurements on the human body to capture that shape.”
Researchers believe that measuring a person’s waist better reflects the body's fat amount than their weight. “By taking weight out of the equation, BRI provides a better indicator of how much belly fat (visceral fat) surrounds the organs inside the abdomen. High amounts of belly fat are linked to high blood pressure, heart disease, diabetes, and some cancers,” Matthew Solan writes at Harvard Health.
A study that followed 33,000 people found that increased BRI is associated with a risk of death compared to those with a lower BRI. For example, those with a BRI of 6.9 had a greater risk of early death than those with a lower BRI of 4.5 to 5.5. Further, those who are older and have lower BRIs (less than 3.4) have a significant risk of death because they may be malnourished due to poor health.
The researchers also found that BRI did a better job at calculating a person’s body composition than BMI. “Our findings provide compelling evidence for the application of BRI as a noninvasive and easy-to-obtain screening tool for estimation of mortality risk and identification of high-risk individuals, a novel concept that could be incorporated into public health practice pending consistent validation in other independent studies,” the authors wrote.
It’s also easy for doctors to calculate in a fast-paced medical setting. “The goal is to have something that can be used by the most number of sites,” Thomas told NBC News. “You don’t need a scan or special scale. BRI only requires a measuring tape.”

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
