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.

With HYROX making waves in India, including the Masters' Union HYROX Delhi event held from July 24 to 26 at Yashobhoomi, Dwarka, many first-time athletes are asking one question: Is just water enough, or do you need electrolytes?

The answer depends on how long, how hard, and how much you sweat during the race. HYROX combines 8 km of running with eight functional workout stations, making it a prolonged, high-intensity event that places significant demands on hydration.

What Is HYROX?

HYROX is a global fitness racing competition that has become increasingly popular this year. Unlike obstacle races, the format of HYROX does not change, giving fitness enthusiasts a way to measure their progress outside the gym.

The sport combines endurance running with functional strength exercises. Every HYROX event follows the same format, allowing participants to compare their times with other athletes worldwide.

Participants are supposed to complete one km run and one workout station with eight repetitions. The workout stations include:

• 1,000 m SkiErg
• 50 m Sled Push
• 50 m Sled Pull
• 80 m Burpee Broad Jumps
• 1,000 m Row
• 200 m Farmer's Carry
• 100 m Sandbag Lunges
• 75 or 100 Wall Balls (depending on division)

Regular Gym-Goers Vs HYROX Athletes: Who Really Needs Electrolytes?

HealthandMe spoke to Dr Akshat Chadha, Lifestyle Medicine Specialist & General Physician, about the importance of electrolytes for physically active individuals. The expert also explains how HYROX athletes must approach electrolytes.

Dr Chadha says, "Electrolytes have become a big market overnight. Electrolytes are important for someone who is participating in a marathon or a high-intensity event like HYROX. It's not important for someone who is just going to the gym or just going for a walk."

Talking about natural electrolytes vs packaged electrolytes, the expert said that regular gym-goers or moderately active individuals don't require store-bought, packaged electrolytes that contain a long list of ingredients.

He says, "Electrolytes is a very generic term. I am talking about packaged electrolytes. You don't really need any packaged electrolytes if you are not doing any high-intensity exercises or if you are not sweating a lot. Basically, you could go for natural electrolytes. If you get tired during a workout, you can take a bottle of water mixed with lemon, salt, and jaggery. That's one of the best natural electrolytes that you can sip during workouts or after workouts."

Dr Chadha also spoke about the kind of electrolytes HYROX athletes should take in order to stay energised and hydrated after a strenuous session. He stresses upon checking the labels and ingredients to avoid buying unnecessarily "enhanced" electrolytes.

He says, "But if someone is preparing for HYROX and wants to take packaged electrolytes, they should choose it carefully. They should look at the ingredients as there are a lot of unnecessary things added to packaged electrolytes to enhance them. Basic electrolytes are more than enough. So, if you need it, then please check the ingredients or talk to an expert before buying it. If someone is preparing for HYROX, they most likely must be under someone's training. So, ask your trainers which is the best electrolytes."

Exercise at the gym is usually seen as helping people build muscle, lose weight, and generally become physically fit. Nevertheless, contemporary research indicates that exercise is not only good for changing someone's physique but also has a significant impact on someone's brain functioning. Thus, a gym visit is an activity that not only develops your muscles but also strengthens your brain to the same extent.

As soon as people start exercising, endorphins, which are sometimes called the "feel good" hormones, start being released into the body. They help to ease stress, anxiety, and depression while also having a positive impact on mood. Exercise also increases the flow of blood to the brain, which delivers more oxygen and nutrients and promotes proper brain functioning.

The Relationship Between Fitness And Brain Efficiency

Moreover, regular workouts help one sleep better. As you know, adequate rest is critical for the brain as it is necessary for its restoration and for developing new memories. In addition, a person who has developed his/her own fitness plan will learn to demonstrate discipline, patience, and set up goals. Achievements in the gym become a source of strength and confidence in other spheres of life.

Although increasing physical strength is one of the most useful outcomes of visiting the gym, the psychological benefits are also very useful. Physical well-being contributes to mental health and allows us to get more energized, concentrated, and emotionally balanced. Regardless of the reason why people work out—whether they want to get in shape, relieve some stress, or perform better at school or work—the visit to the gym will definitely be beneficial.

To conclude, the gym is not only the place to develop physical strength; it is the place where the brain develops as well. By improving our moods, memories, attention, and discipline, exercising shows that we build far more than just physical health.

We spend a lot of time worrying about skin, hair, weight, and even gut health, but we often ignore our joints.

We depend on our joints for every step, squat, staircase climb, and grocery run. Knees alone absorb forces several times body weight during ordinary activities. Globally, an estimated 595 million people were living with osteoarthritis in 2020, roughly 1 in 13 people on the planet, and a 132% increase in total cases since 1990. Alarmingly, many of us are making lifestyle choices that place unnecessary stress on our joints long before we hit our forties or fifties.

While ageing is the main cause of joint pain, stiffness, and reduced mobility, these issues are increasingly showing up in younger adults, too.

Here are five common habits that could be quietly working against your joint health.

Mistake #1: Improper Footwear Choices

It is really important that your footwear has adequate cushioning or support. The impact of every step travels upward through your ankles, knees, hips, and lower back. Your footwear plays the role of a shock absorber. Gradually, repetitive stress placed on your feet contributes to discomfort, especially if you spend long hours standing, walking, commuting, or exercising.

It is important to choose footwear that suits your activity level. If you exercise regularly, make sure your shoes match the type of movement you are doing, and replace them once the support wears out.

Mistake #2: Going All-In on Cardio and Calisthenics Without Guidance

Social media has made fitness more accessible than ever. It's also convinced a lot of people that every workout needs to be intense. High-volume jumping drills, excessive running, deep-impact movements, and advanced calisthenics performed without proper progression can overload joints, tendons, and ligaments. Unlike muscle, the cartilage cushioning your joints has no blood supply and very limited ability to repair itself once damaged, which is why overuse injuries can have lasting consequences rather than simply healing with time.

Joint problems are often linked to poor exercise choices, but inadequate recovery can also impact them. Not giving enough rest, nutrition, or recovery time causes tissues to suffer due to the stress being placed on them, leading to aches, pains, and overuse injuries.

Focus on gradual progression, proper technique, adequate recovery, and a balanced routine that includes strength training, mobility work, and rest days.

Mistake #3: Constantly Cracking Your Knuckles and Joints

While knuckle cracking is not directly responsible for arthritis, habitual and forceful joint manipulation can irritate surrounding soft tissues and become a repetitive stress habit over time.

Medical attention may be required if cracking is accompanied by pain, swelling, locking, or instability.

Mistake #4: Ignoring the Nutrition Side of Joint Health

Many diets fall short on two nutrients that matter a lot for musculoskeletal health: calcium and vitamin D. Calcium builds and maintains bone strength. Vitamin D helps the body absorb and use it. Inadequate intake of either results in weaker bones, in turn causing poor joint health. Excess body weight adds another layer to this. Not just as an added mechanical load on the joints, but because fat tissue actively releases inflammatory compounds that can accelerate cartilage breakdown. This makes joint health a metabolic issue, not just a structural one.

Calcium sources include milk, yoghurt, paneer, cheese, ragi, sesame seeds, tofu, almonds, and green leafy vegetables. Vitamin D sources include safe sunlight exposure, egg yolks, fatty fish, and fortified dairy products.

Mistake #5: Sitting for Most of the Day

Long hours at a desk, extended scrolling sessions, and prolonged sitting can weaken the muscles that support the joints. This leads to stiffness, poor posture, and mobility issues. Inactivity can also set off a compounding cycle: as joints become less stable and more uncomfortable, people tend to move less to avoid pain, which leads to further muscle weakening, reduced joint support, and faster deterioration over time. Standing up regularly, taking walking breaks, stretching between meetings, and using the stairs keep joints mobile and well-supported.

The Bottom Line

Joint health is the result of small decisions made consistently over time: the shoes you wear, how you exercise, what you eat, and how much you move. Most joint problems don't appear overnight, and many of the habits that lead to them can be corrected before they become long-term issues.
