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.

High blood pressure (BP) has become a public health problem that is driving cardiovascular diseases like heart attacks and strokes globally. While medications are important to keep hypertension under control, lifestyle changes and healthy practices are also crucial.
Several global health guidelines recommend regular physical activity, but adhering to exercise programs daily becomes a challenge for many people. But in the overtly busy schedules, sparing 10 minutes for an exercise regimen can be easier than travelling to the gym.
A large randomized clinical trial, published in the Journal of the American College of Cardiology (JACC), has proved that a traditional Chinese mind-body practice — baduanjin — may help lower blood pressure, that too, without any equipment.
Baduanjin is a slow, structured movement, focused on deep breathing and meditation.
Importantly, the clinical trial proved that the ancient Chinese technique could lower BP as effectively as brisk walking.
In people practicing baduanjin, BP reductions were seen after three months and were sustained for one year.
"Given its simplicity, safety, and ease with which one can maintain long-term adherence, baduanjin can be implemented as an effective, accessible, and scalable lifestyle intervention for individuals trying to reduce their blood pressure," said Jing Li, Director, National Center for Cardiovascular Diseases in Beijing, China.
Baduanjin is a standardized eight-movement sequence that integrates aerobic, isometric, flexibility, and mind-body components.
It has been in practice for centuries and commonly performed in community settings across China. The routine typically takes 10–15 minutes and requires no equipment and only minimal initial instruction.
Because it is low- to moderate-intensity, it is considered safe and accessible for many adults.

A team of Chinese researchers led the first large, multicenter randomized trial to look at the impact of baduanjin on blood pressure.
They followed 216 participants, aged 40 years or older, across seven communities to determine changes in 24-hour systolic BP from baseline to 12 and 52 weeks.
Compared to people indulging in self-directed exercise, practicing baduanjin five days a week reduced
Notably, the benefits were sustained even without ongoing monitoring, a key challenge for many lifestyle interventions that struggle to maintain long-term adherence outside structured programs.
"Baduanjin has been practiced in China for over 800 years, and this study demonstrates how ancient, accessible, low-cost
approaches can be validated through high-quality randomized research," said Harlan M. Krumholz, Editor-in-Chief of JACC and the Harold H. Hines, Jr Professor at the Yale School of Medicine.
"The blood pressure effect size is similar to that seen in landmark drug trials, but achieved without medication, cost, or side effects. This makes it highly scalable for community-based prevention, including in resource-limited settings," they added.

If you believe only gym workouts matter, you might be mistaken. While gyms offer a structured space to exercise, busy schedules often lead many to skip workouts—and feel guilty about it.
However, a new study suggests that even short bursts of vigorous everyday activity—such as running to catch a bus or climbing stairs quickly—can significantly reduce the risk of several major diseases and even lower the risk of death.
The research, based on nearly 96,000 people and published in the European Heart Journal, found that just a few minutes of intense activity each day was linked to a lower risk of:
“We know that physical activity reduces the risk of chronic disease and premature death, and there is growing evidence that vigorous activity provides greater health benefits per minute than moderate activity,” said Minxue Shen from the Xiangya School of Public Health, Central South University, China.

To explore whether exercising more intensely offers greater benefits than simply exercising longer, the researchers followed 96,408 participants for seven years.
Each person wore a wrist-based accelerometer to track movement, including short bursts of activity often overlooked.
The findings showed that compared to those who did no vigorous activity, participants with the highest levels had:
“Our findings suggest that adding short bursts of activity that make you slightly breathless—like climbing stairs quickly or walking briskly between tasks—can have substantial health benefits,” Shen said.
“Even 15–20 minutes per week, just a few minutes a day, can make a meaningful difference,” the Professor added.

The World Health Organization (WHO) recommends that adults (18–64) perform at least 150–300 minutes of moderate-intensity aerobic physical activity, or 75–150 minutes of vigorous-intensity activity per week.
The new study suggests that intensity also plays a key role—and may vary depending on the disease being prevented.
The researchers noted that these findings could help shape more personalised exercise recommendations in the future. However, they cautioned that vigorous activity may not be suitable for everyone, particularly:
Rohit Sharma also smashed his fastest IPL 50 on Sunday against KKR.
IPL 2026 is back, and for fans of cricket, it is the most amazing and eagerly awaited time of the year. Eight exceptional teams, an incredible line-up of cricketing sensations from all over the world, and an unforgettable clash of titans — IPL deserves all the hype it gets. And after last night's incredible battle between Kolkata Knight Riders and Mumbai Indians, former captain Rohit Sharma also deserves all the hype he is getting. Not only did the Hitman score his fastest IPL 50, but he also managed to impress everyone with his transformation. Nita Ambani, Chairperson and founder of the Reliance Foundation and Dhirubhai Ambani International School, and a director of Reliance Industries (owner of the Mumbai Indians team too), was awestruck to see a fitter version of Sharma.

In a recent video shared on the Instagram page of Mumbai Indians, Nita Ambani is seen meeting the squad as they were training ahead of the 2026 IPL. As she encounters Sharma, she says, "My God, Rohit, I didn’t recognise you! You look like a young boy."
Rohit Sharma, now 38, will be turning 39 on April 30, but to a fan's eye, he seems to be ageing in reverse. On May 7, 2025, Sharma announced his retirement from Test cricket. Earlier in 2024, he announced his retirement from T20Is after the 2024 World Cup win. Since then, he has focused primarily on ODIs and, as it turns out, on becoming a fitter version of his current self.

A fitter Rohit Sharma since retirement
Rohit Sharma smashed an impressive 78 off 38 balls in last night's match against KKR, and perhaps his success can be credited to his recent transformation. His physical transformation took place ahead of the Vijay Hazare Trophy, and he lost an impressive 11 kilos before returning to the game. But what his fans loved most is that he was never really lagging because of the extra weight — he was always fit, quick and proactive, but now he is a lot leaner on the outside. How did the former skipper achieve this goal? Let’s find out:
Cardio workouts like interval training, running and cycling help build stamina and endurance — these help ensure peak performance during stressful matches.
