BMI has been the benchmark in evaluating health and fitness for many years. The formula is quite simple: weight in kilograms divided by the square of height in meters. This would easily tell if one is underweight, within the healthy weight range, overweight, or obese. But with new research findings, scientists are now questioning its accuracy and usefulness as a total measure of body composition.
The report, published in The Lancet Diabetes & Endocrinology, has sparked a global conversation on rethinking BMI. Supported by more than 50 international medical experts, the report suggests classifying obesity into "clinical" and "pre-clinical" types for better diagnosis and treatment. The shift underscores a growing consensus: BMI alone may not tell the full story of your health.
While BMI is simple to calculate and universally accessible, it is far from perfect. It does not consider muscle mass, bone density, or fat distribution, leading to misleading conclusions in some cases. For example, athletes with a high muscle mass may be considered overweight, whereas individuals with normal BMI might carry unhealthy amounts of visceral fat.
A landmark study in JAMA Network Open studied more than 155,000 postmenopausal women and found that women with a normal BMI but a waist size over 35 inches were more likely to die from heart disease or cancer compared with their counterparts whose waists are smaller. That makes a great case for how BMI can be insufficient and fat distribution must be factored into account.
Not all body fat is equal. Subcutaneous fat, which lies just beneath the skin, is relatively harmless. The real health danger lies in visceral fat—fat that surrounds internal organs. Unlike subcutaneous fat, visceral fat is metabolically active, releasing stress hormones like cortisol and inflammatory substances that raise blood pressure, blood sugar, and cholesterol levels. These effects significantly increase the risk of conditions such as heart disease, type 2 diabetes, and certain cancers.
Since BMI is not the most reliable measure, scientists and doctors have sought other means to measure body composition more accurately.
A simple tape measure can provide valuable insight into your health. Measure your waist at the level of your belly button, ensuring the tape is parallel to the ground. For women, a waist measurement under 35 inches is considered healthy, while for men, the goal is under 40 inches.
This is the ratio of your waist circumference to that of your hips. To calculate it, divide your waist measurement by your hip measurement. According to the National Center for Biotechnology Information, a ratio under 0.8 for women and 0.9 for men is considered healthy.
A newer method that seems to be receiving more attention involves the Body Roundness Index or BRI: height, weight, and girth are placed together to represent a more advanced view of what body composition says. Research presented in JAMA Network Open offers evidence that this BRI predicts mortality risk greater than BMI in some cases- a promising weapon for public health.

The good news is that visceral fat responds well to lifestyle changes. Here are three evidence-based strategies:
Adopting an eating window of 12 hours—such as from 7 a.m. to 7 p.m.—can significantly reduce visceral fat, according to a study published in Nutrition Research Reviews. This approach not only helps control caloric intake but also reduces late-night snacking, a known risk factor for abdominal obesity.
Excessive alcohol consumption is associated with increased belly fat. A 2017 study published in Public Health Nutrition revealed that alcohol increases the levels of insulin and encourages the storage of fat in the abdominal area. Limiting alcohol to occasional indulgence helps avoid weight gain in this region.
HIIT involves repeated episodes of high-intensity exercise separated by periods of rest. A review in *Sports Medicine* concluded that HIIT is very effective in reducing visceral and total body fat. It can be noted that adding just 20 minutes of HIIT two times a week can make all the difference.
The reliance on BMI as a sole indicator of health is increasingly being challenged. While it remains a convenient screening tool, its limitations necessitate a broader approach that considers factors like fat distribution, waist circumference, and new metrics such as BRI.
In the simplest of words, health is multi-dimensional, and shifting perspectives from considering weight solely to broader measures of body composition will get people a much clearer understanding of where their health risks are so that they can take the action required for a better quality of life. Through adjustment to diet, exercise, or perhaps through innovative metrics like BRI, health is well within reach of the individual.
This dynamic conversation raises the point about personalized health screenings, which helps everyone get more relevant tools fitting their unique lives and circumstances. As body composition research is enhanced, so do the futures look brighter and brighter for the times of measurement when it comes to health.

A New York City teacher Pedro Soto, 56, who teachers at the Manhattan school had a simple sore throat and he believed it was from a viral infection, but it soon turned out to be type 2 diabetes.
This was in April 2024, when he went to his doctor with the complaint of a sore throat and took a blood test. This is when he was "officially diagnosed with type 2 diabetes".
In an interview with PEOPLE, he tells while the doctor recommended medications for him, he was determined to make a lifestyle change first. "After receiving the news, I chose not to start medication right away. Instead, I committed to exercising, running twice a week and improving my diet."
Turns out, running, changed his life.
Pedro Soto first considered running the TCS NYC Marathon after a colleague mentioned that her husband had completed it. Motivated, he applied through a special program for teachers, sharing an essay about his type 2 diabetes diagnosis. His story earned him a spot on the team. As he trained, he closely monitored his health, undergoing regular blood tests every three months. The improvement surprised him. His blood sugar levels, once concerning, gradually returned to the normal range. While type 2 diabetes cannot be fully cured, it can be reversed, and Soto was seeing that transformation firsthand.
The marathon was scheduled for November 2, 2025. Soto’s training, however, didn’t begin smoothly. In June, he learned he had Lyme disease. Around the same time, he lost his father. Because of these back-to-back challenges, he wasn't able to train consistently until August. Running soon became more than exercise. It became a way to navigate grief and rebuild strength.
He describes those months as emotionally heavy. Running offered him space to reflect, heal, and feel close to his father. It became a ritual that allowed him to confront his feelings rather than avoid them.
To prepare mentally, Soto dove into YouTube videos and articles about the marathon. Still, nothing compared to the real thing. To him, race day felt like a citywide block party. The cheering crowds, music, and energy made the pain more bearable. He said that although the long hours of pounding take a toll on joints and muscles, the city's encouragement kept pushing him forward.
The toughest stretch came in the final six miles, when self-doubt crept in. What kept him going was thinking about his students. Soto works with teenagers in a transfer program, many of whom have struggled in traditional school systems. Their perseverance inspired him. If his students could show up every day despite their challenges, he believed he could finish the race.
He says he is taking care of his health and this itself is an act of commitment to his students. Whenever he feels healthier, he shows up as a strong educator and for him the marathon teaches him the importance one needs in life of balance, self-care, and knowing when to put themselves first.

"I'm excited for this next chapter in my life, I'm the happiest I've ever been, and for since I could remember I was sad," said Post Malone as he talked about his journey of losing 55 pounds. He went from 240 lbs to 185 lbs, he revealed at The Joe Rogan Experience Podcast. His inspiration? His daughter. He said that he is focused more on his health since becoming a father.
"It is definitely made me take better care of myself. I want to be around to see her go and do kick-*ss stuff. And before, you know, I was really drinking a lot and smoking a lot and stuff. I kind of took everything and toned it down a little bit and, you know, doing my best and really got my weight going," he said.
His weight loss journey started after he welcomed his daughter in May 2022, and on April 20233, he shared on his Instagram that post becoming a father he is now prioritizing his health.
He said it is simple, he decided to "kick soda and start eating better". He also is trying to cut down his smokes and brews or give up completely, which is taking time.
On his Instagram post, he wrote: "I've had a lot of people ask me about my weight loss and I'd suppose, performance on stage. I'm having a lot of fun performing, and have never felt healthier. I guess dad life kicked in and I decided to kick soda and start eating better so I can be around for a long time for this little angel. Next up is smokes and brews, but I like to consider myself a patient man... lol!"
While his fans were initially concerned about his weight loss, he reassured them that his "brain is in a super dope place" and he was "the happiest" he has ever been in a long time.
When he made his appearance in June 2024, on The Joe Rogan Experience Podcast, he said that his fans in fact, thought, that he started using drugs, due to his drastic weight loss. This is why he posted on Instagram to deny those allegations. “I remember, whenever I started losing my weight, everybody was like, ‘Hey, this is what meth looks like,’ and I started dancing on stage and having fun and having more energy and just enjoying life again, you know what I mean,” he told host Joe Rogan. “Like I mentioned, I was s***** for a long time, but I had my baby and I’m in a great f****** spot and then the first thing that happens is like, ‘Oh he’s on f****** drugs.’"
However, Malone has confirmed that he is not "any hard drugs".
In an appearance on The Howard Stern Show in October 2023, Malone said that he has not been on weight loss medication, rather he is now making better food choices.
Earlier, whenever he was on tour, he would go for junk, but now, he has made a deliberate choice to eat "grilled chicken" "carrots" with a "little bit of white rice with hot sauce". He said he was blown away to find out that hot sauce has no calories.
He also shared that he has cut out fried food and pizza. He shared that he would previously eat a lot of junk while on tour, especially because those places were open at 2 am after a show. However, when he made those small dietary changes, he lost 20 pounds, which made him think "let's keep building".
He also shared that he started cutting down on his soda intake. However, he would occasionally reward himself with one after a show.
He also showed off his weight loss in an August 2023 Instagram post on a mirror selfie and wrote: "Introducing Viceroy Chungus VonBattlepass, i love you," in caption.

For years, the idea of walking 10,000 steps a day has been treated like universal fitness wisdom, however, a recent study reveals that even a short stroll too could help you stay healthy.
From fitness trackers to morning-walk groups, the number has been repeated so often that many people believe it is a scientifically proven rule. The truth is far simpler and far more encouraging. New research shows that you do not need anywhere near 10,000 steps to improve your health. In fact, even a small amount of regular movement can dramatically lower your risk of heart disease and early death.
A new study published in the British Journal of Sports Medicine examined how step counts influence longevity and heart health, particularly in older adults. The findings were surprisingly optimistic. Scientists discovered that walking as few as 4,000 steps in a day, even if you manage this number only one or two days a week, can reduce the risk of death by 26 percent. It can also lower the risk of heart disease by 27 percent when compared to those who barely moved.
The benefits became even more striking when participants achieved the 4,000 step target on more than three days per week. In that group, mortality dropped by more than 40 percent and the risk of heart issues fell by 27 percent. These numbers show that moderate, regular walking has powerful protective effects on long-term health.
The study also explored whether aiming for higher step counts brings additional benefits. Researchers found that walking around 7,000 steps a day provides a slight extra advantage when it comes to living longer. However, it does not significantly change cardiovascular outcomes. This means that hitting 4,000 steps is already enough for meaningful protection, especially for older adults or people who are unable to reach higher counts.
Interestingly, the study also revealed that the number of days you walk matters far less than the total steps collected throughout the day. When scientists adjusted for total daily steps, the link between how many days people walked and their health results disappeared. The real takeaway is this: what matters most is how much you move overall, not whether you meet a daily or weekly quota.
Walking is one of the simplest forms of movement, yet its benefits are remarkably wide-ranging. It is gentle, low impact and accessible to almost everyone. Regular brisk walking has been shown to improve heart health, support weight management, boost mental well-being and improve mobility. These improvements occur because consistency helps the body adapt, even when the total effort seems small.
For older adults, or for anyone returning to activity after a long pause, this consistency is especially important. Small, steady efforts accumulate and gradually build up stamina. Over time, this reduces the risk of chronic disease and enhances overall fitness without stressing the joints.
If you want to enjoy the health benefits of walking, the key is to stay consistent rather than chase big numbers. A few practical tips can help you build a routine that feels realistic and enjoyable.
If you have been inactive for a while, begin with five to ten minutes of walking at a comfortable pace. Gradually increase your duration and distance over several weeks. This prevents strain and reduces the risk of giving up too soon.
Aim for manageable targets such as walking 20 to 40 minutes three days a week. Once this feels comfortable, you can add more time or increase your frequency if you wish.
If you are traveling or have long work hours, try breaking your walks into shorter chunks. A few five to ten minute walks throughout the day can help you stay on track.
When outdoor conditions are not ideal, choose indoor spaces such as malls, gyms, community centers or even long corridors at home or work.
Different routes help fight monotony and make walking more enjoyable. Rotate between parks, neighborhoods or indoor spaces to keep things fresh.
