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.

BMI Isn't Always the Best Measure of Body Composition — Here's What to Use Instead

Since BMI is not the most reliable measure, scientists and doctors have sought other means to measure body composition more accurately.

1. Waist Circumference

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.

2. Waist-to-Hip Ratio

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.

3. Body Roundness Index (BRI)

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.

Ways To Cut Off Unhealthy Fat

The good news is that visceral fat responds well to lifestyle changes. Here are three evidence-based strategies:

Time-Restricted Eating

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.

Limit Alcohol Intake

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.

High-Intensity Interval Training (HIIT)

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.

We have all seen people who are naturally good at any sport they pick. While anyone can practice sports and get better, there is a question of whether the other people who play better are ‘gifted’ or are they doing things differently. The answer could be both! There are certain people who are naturally better at sports, and research has shown that there is a simple sign that may indicate the same.

Take a look at your hand right now. Is your ring finger longer than your pointer (or index) finger? If it is, new research suggests you might have a natural gift for sports. Published in the American Journal of Human Biology, the study looked at many smaller studies, found that people whose pointer fingers are shorter than their ring fingers (this is called a lower 2D:4D digit ratio) tend to have better endurance and exercise tolerance tougher and longer workouts better.

This research is thought to be the most complete study so far that connects finger length to how well people can exercise and perform in endurance activities. One expert from the study explained that if you have this lower digit ratio, you're more likely to do well in sports that need a lot of stamina, like long-distance running, biking, rowing, or team sports that require a lot of energy. This finger ratio could even be a cheap and easy way to check someone's basic heart and lung fitness.

Study Found About Fitness and Finger Length

The researchers looked at 22 different studies that included over 5,000 people from 12 countries. They specifically checked how the lengths of people's pointer (2D) and ring (4D) fingers were related to how fit their heart and lungs were. This included how well their bodies used oxygen during hard exercise and how long they could work out before getting tired.

The results showed that people with a lower 2D:4D ratio (meaning their pointer finger was shorter than their ring finger) had better exercise tolerance and could keep going longer. However, this finger ratio didn't seem to be linked to other athletic abilities, like how much oxygen their body could use overall.

Can Finger Length Predict Other Things About Your Health?

Other studies have also connected finger length ratios to different traits, like being more physically aggressive or more competitive. The lower 2D:4D ratio has also been linked, though not strongly, to other signs of being good at sports, such as having a stronger grip, being able to sprint faster, and having more explosive power. Some research suggests this link is stronger in men and in sports that need a lot of stamina or sudden bursts of power.

A few studies have even found that people with lower 2D:4D ratios have bigger jumps in the hormone testosterone during tough exercise, which might help them deal with discomfort. Also, top athletes often have lower 2D:4D ratios than people who aren't athletes. However, experts point out that this isn't true for every sport, and the effect is usually small.

Other scientists, however, question how much finger length really matters in sports. They believe it's unlikely that finger size can truly predict someone's ability to endure. Most of the research on finger ratios has only shown connections, not direct causes. More studies are needed to clearly understand why these links exist and if they have any real use in finding talent or in athletic training.

What definitely does improve your fitness, according to experts? Training. Regular exercise, both cardio and strength training, can hugely improve your heart and lung fitness. It's much more likely that your training will affect your performance than your finger length.

If you’re aiming to improve your running speed and endurance, it may be time to shift your gaze — quite literally. A new study suggests that narrowing your focus while running, especially as you near the finish line, can help you move faster and push harder.

The research, published on June 25 in the journal Personality and Social Psychology Bulletin, looked at the performance of nearly 1,600 runners across six separate studies. Conducted by researchers from Rutgers University, New York University, and Creighton University, the findings point to a low-cost and highly effective strategy known as “attentional narrowing.”

Put simply, runners who directed their gaze straight ahead — instead of looking around — not only moved faster but also exerted more physical effort.

Attentional Narrowing: What the Science Says

“The findings offer a low-cost and simple way to improve running performance — merely by adjusting how we direct our attention,” said Dr. Shana Cole, associate professor of psychology at Rutgers University-New Brunswick.

In the study, both elite and casual runners were surveyed and tested. Some participants were asked to maintain a narrow focus throughout their run, while others were instructed to shift their attention only in the final stretch. The races varied between 400 meters and one mile, but the result was consistent: those who fixed their eyes on a single point ahead — like the finish line — ran faster and registered higher heart rates, indicating increased effort.

“Looking at one spot ahead of you — rather than around you — can help you keep going,” added lead author Emily Balcetis, associate professor of psychology at New York University.

Co-author Corey Guenther, psychology professor at Creighton University, emphasized that the mental strategy doesn’t just correlate with better results — it causes them. “The studies show that narrowing attention isn’t just correlated with performance. It actively enhances it,” he said.

Why Running Is Already Good for You

This simple mental tweak could make running even more beneficial — and that’s saying something. Running is well-known for its wide-ranging health perks. According to a 2019 study published in the British Journal of Sports Medicine, even small amounts of running (as little as once a week) are associated with a significantly lower risk of death from all causes, including cardiovascular disease and cancer.

Running also helps with weight control, strengthens the heart, improves sleep, and releases endorphins — the feel-good hormones — which help reduce stress and anxiety. The Centers for Disease Control and Prevention (CDC) recommends at least 150 minutes of moderate-intensity aerobic activity per week for adults, and running is a quick and efficient way to meet that goal.

The Takeaway: Pick a Spot and Go for It

The study findings offer a practical, science-backed takeaway: when running, particularly in challenging stretches, resist the urge to look around. Instead, fix your eyes on a point ahead — a tree, a marker, or the finish line — and stay focused.

As Balcetis explained, “A simple shift in attention can lead to better outcomes — mentally and physically.”

So the next time you're out on a run, remember: where your eyes go, your legs may just follow.
