Using BMI To Classify People As Obese Is Flawed Say Experts

Updated Jan 16, 2025 | 11:57 AM IST

SummaryBMI is used to classify individuals as underweight, healthy weight, overweight, or obese based on their height and weight. It is calculated by dividing weight in kilograms by health in meters squared. However, there are reasons while it falls short.
BMI Not the right way to measure obesity

A new report published in The Lancet Diabetes & Endocrinology challenges the conventional definition of obesity, and urges a shift from the reliance on Body Mass Index (BMI) to a more nuanced approach. This is supported by over 50 global medical experts. The report also recommends splitting the term "obesity" into two categories: "Clinical obesity" and "Pre-clinical obesity". This aims to improve diagnosis and treatment for over a billion people worldwide living with obesity.

Clinically Obese

This applies to individuals whose obesity has progressed to a disease state, manifesting in organ damage, heart disease, type 2 diabetes, or other health complications. These individuals could also experience symptoms like breathlessness, joint pain, or impaired daily functioning. Treatment also involves medical interventions, including weight-loss medications or surgery.

Pre-Clinic Obese

Whereas the term "pre-clinic obese" refers to those who are overweight but not yet exhibiting health issues. While they may be at risk of developing obesity-related conditions, their organ function and overall health remain intact. What they need is preventive care, which includes dietary guidance, counselling, and regular monitoring to avoid and reduce future health risks.

What does the study say?

The study, led by Professor Francesco Rubino from King's College London emphasizes that obesity is not one-size-fits-all condition. This means it should rather be treated as a spectrum as some individuals maintain normal organ function despite being classified as obese. There are others who may face severe health complications too. However, the current method of calculating obesity based on BMI often leads to misdiagnosis or inadequate care.

The report also states that BMI, while is useful for analyzing population trends, is a flawed unit of measuring individual health. Therefore, there is a need to redefine obesity, and healthcare professionals can provide more precise care by distinguishing those who need immediate medical intervention and those who require preventive strategies.

Limitations of BMI, Why It Falls Short?

BMI is used to classify individuals as underweight, healthy weight, overweight, or obese based on their height and weight. It is calculated by dividing weight in kilograms by health in meters squared. However, there are reasons while it falls short.

•Muscle vs Fat: Athletes or muscular individuals often have high BMIs despite the low body fat

•Fat Distribution: BMI does not measure fat around the waist or organs, which could be more dangerous to one's health.

•Individual Health Variation: It also overlooks the specific health conditions such as heart diseases or diabetes, or any other, while evaluating a person's category in terms of weight.

Scope Of Study

By redefining obesity, the study could transform the approach to diagnosis and treatment. It can focus on individual health risks rather than BMI alone. Healthcare providers can also offer tailored care. This also will ensure hat weight-loss medications like Wegovy or Mounjaro are prescribed only to those who genuinely require it.

As per Professor Louise Baur from the University of Sydney, a Children's obesity expert said that this redefinition allows both adults and children to receive more appropriate care while reducing over-diagnosis and unnecessary treatments.

Déjà Vu is a feeling of sensation when one person feels that they have felt or witnessed the same situation before, just like a single incident is happening once again. The word itself is from French and means "already seen." Though there is a common misconception among people that Déjà Vu is a very rare occurrence, in reality, this apparently mysterious experience happens to almost 97 percent of people's lives. Thus, it is a very common thing that will be felt by most people at least once in their lifetime.

What Is Déjà Vu?

As mentioned before, the word itself shows the very aspect of Déjà Vu that it's already seen. Suppose you are having a deep conversation with your friend, family, or a stranger, but you feel like this is not the first time you are having this conversation; you already know the topics and outcomes, as if you are living the same moment that you have lived before.

On the other hand, you might be visiting a new place, maybe a new city that you have never visited, but the places, houses, and overall atmosphere feel very recognizable. You suddenly feel that you have visited that place before and have felt good or bad in the past, as if you are living a past in your present.

All in all, this kind of strange phenomenon that happens to people regularly, this kind of uncomfortable feeling which is felt by 97 percent of people in the world, is called Déjà Vu.

What Causes Déjà Vu?

The root cause of this strange phenomenon is believed to be a result that one place or any conversation or any situation is resembling the same kind of pattern or feelings that you have experienced and felt before, and in most cases, you yourself have forgotten that, but your brain has not, and it recreates this sense of familiarity, and you feel you are living in a paradox.

In other words, déjà vu occurs when two parts of your brain fail to communicate properly: the temporal lobe, which handles memories, and the hippocampus, which processes new experiences.

There are certain things that can cause Déjà Vu more than others, such as fatigue or sleep deprivation, stress, and anxiety, which can trigger the feeling of Déjà Vu, as this pressure on your mental and physical health might pressure your brain and distort the recognition process. Other than that, migraine, dementia, and seizure can also cause Déjà Vu in a person.

Occasional déjà vu is generally harmless and not a cause for concern. However, if it happens frequently, lasts more than a few seconds, or is accompanied by other symptoms, it may be a good idea to seek medical advice.

Why Sleeping Pill Addiction Is Common Among Football Players

Updated Jun 15, 2026 | 07:00 PM IST

SummaryDr. Chandran, currently President of the Indian Federation of Sports Medicine (IFSM), said that while players may turn to sleeping pills as a quick solution, regular use can become a habit that leads to dependence if left unchecked.

As the FIFA World Cup 2026 is underway, players are navigating demanding training schedules, frequent travel, challenging weather conditions, and the pressure to perform at their peak. Amid these challenges, many elite footballers quietly face an often-overlooked problem off the field: sleep disturbances.

In an exclusive interview with HealthandMe, Dr. P.S.M. Chandran, former Director of Sports Medicine at the Sports Authority of India (SAI), said that the stress, anxiety, and disrupted routines associated with elite sport can make it difficult for players to get adequate rest. In some cases, these challenges may drive athletes toward sleeping medications, potentially affecting both their health and on-field performance.

Dr. Chandran, currently President of the Indian Federation of Sports Medicine (IFSM), said that while players may turn to sleeping pills as a quick solution, regular use can become a habit that leads to dependence if left unchecked.

Recently, striker Omar Bogle, who plays for Crewe Alexandra in League Two, shared his story with The New York Times' The Athletic about the moment last year when he became addicted to sleeping pills and painkillers.

What began as a way to help him sleep after suffering a back fracture during pre-season in the summer of 2024 became an addiction.

From January 2025, his usage accelerated to an alarming level. He said that many of the pills he was taking were benzodiazepines, such as diazepam and lorazepam. He was also using the stronger zopiclone pills, which the NHS says can be prescribed for the short-term treatment of severe insomnia.

"No one knew the extent of what I was doing," he said. "I never told anyone I was popping 18 or 19 of the things in the night."

Bogle's is not alone.

In January 2026, former England midfielder Jonjo Shelvey revealed on a podcast how he had become addicted to sleeping pills because of the loneliness he experienced while playing in Turkey. Shelvey said his dependence affected his relationship with his children.

Former Manchester United midfielder Darron Gibson also developed a sleeping pill addiction and, at his worst point, was taking 12 to 14 tablets a night, according to The New York Times.

In 2023, former Tottenham Hotspur and England midfielder Dele Alli told the BBC that he had become addicted to sleeping pills to block out past traumas.

According to Dr. Chandran, the issue is not unique to football but affects athletes across multiple sports, driven by stress, performance pressures, injuries, and demanding schedules.

"Football is not an exception," Dr. Chandran said. "Because of its popularity, we hear more about football players, but athletes in other sports face similar problems."

Why Elite Footballers Face Sleep Issues?

Elite footballers operate in a high-pressure environment where careers can be influenced by contracts, team selection, injuries, and performance expectations. Frequent travel, changing time zones, training camps, and irregular eating patterns can further disrupt normal sleep cycles.

According to Dr. Chandran, these factors create significant psychological stress, making it difficult for athletes to unwind and get adequate rest.

"Athletes are always stressed because of their contracts with clubs, their interaction with coaches, and concerns about injuries that can affect their income," he explained. "All these tensions bring stress, and stress leads to sleep disturbance."

Why Athletes Turn to Sleeping Pills

Sleep plays a crucial role in athletic recovery. Without adequate rest, muscle repair, mental focus, and physical performance can suffer.

"If athletes do not get good sleep, the next day's training will suffer," Dr. Chandran said. "To get better sleep, they try sleeping pills. That becomes an escape route for them."

However, he warned that regular use of sleeping medications can quickly develop into dependence.

"Once they start taking sleeping pills, it becomes a habit. It is difficult to get out of it," he told HealthandMe.

The expert noted that while occasional use under medical supervision may be appropriate in certain situations, unsupervised and prolonged use can worsen sleep problems and lead to dependence.

The Role of Stress Hormones

Stress hormones such as cortisol, adrenaline, and noradrenaline are naturally involved in exercise and performance. However, elevated stress levels can interfere with healthy sleep patterns.

These hormones increase alertness, heart rate, and metabolic activity—responses that may be useful during competition but can make it difficult to fall asleep afterward.

Dr. Chandran emphasized that athletes should seek professional guidance when dealing with sleep issues rather than relying on self-medication.

Recovery Is Key to Performance

Modern sports science places a strong emphasis on recovery, recognizing it as an essential component of performance. Elite football clubs now employ teams of physiotherapists, psychologists, nutritionists, doctors, and recovery specialists to help athletes maintain optimal health.

"Training leads to tiredness, and tiredness has to be overcome by recovery methods," Dr. Chandran said. "The better you recover, the better you can perform the next day."

Implant Dentistry Beyond Replacement: How It Restores Quality of Life

Updated Jun 15, 2026 | 06:00 PM IST

SummaryBy restoring the ability to eat, speak, smile, and engage confidently in daily life, implant dentistry offers benefits that extend far beyond the replacement of a missing tooth.

The loss of a tooth is often viewed as a purely dental concern, but its impact extends far beyond appearance. Missing teeth can affect chewing efficiency, speech, facial structure, and even emotional well-being. While traditional tooth replacement options have served patients for decades, modern implant dentistry has transformed the way tooth loss is managed. Today, dental implants are not merely about filling a gap; they are about restoring function, confidence, and overall quality of life.

Restoring Natural Function and Comfort

Dr. Achuth M. Baliga, Director, Happiest Pearls, said, "One of the greatest advantages of dental implants is their ability to closely replicate the function of natural teeth. Unlike removable dentures that may shift or cause discomfort, implants are anchored securely within the jawbone, providing exceptional stability. This allows individuals to chew a wider variety of foods with confidence and comfort."

The expert went on to say that proper chewing is essential for nutrition and digestive health. Patients who struggle with missing teeth often avoid certain foods such as fruits, vegetables, nuts, and proteins, potentially compromising their dietary intake. By restoring full chewing efficiency, dental implants help individuals maintain a balanced and nutritious diet, contributing to better overall health. Dr Baliga also answered more FAQs on the subject.

Preserving Jawbone and Facial Structure

Tooth loss triggers a process known as bone resorption, where the jawbone gradually deteriorates due to the absence of stimulation from the tooth root. Over time, this can lead to changes in facial appearance, including a sunken or prematurely aged look.

Dental implants address this challenge by functioning like artificial tooth roots. They stimulate the surrounding bone during everyday activities such as chewing, helping to preserve bone volume and density. This not only supports long-term oral health but also helps maintain natural facial contours. In many cases, implants play a significant role in preserving a youthful appearance and preventing the structural changes associated with prolonged tooth loss.

Rebuilding Confidence and Self-Esteem

The psychological effects of missing teeth are often underestimated. Individuals may become self-conscious about smiling, speaking, or interacting socially. Concerns about appearance can affect personal relationships, professional interactions, and overall self-confidence.

Dental implants provide a fixed and natural-looking solution that blends seamlessly with surrounding teeth. The ability to smile without hesitation and speak without worrying about movement or instability can have a profound impact on emotional well-being. Many patients report feeling more confident in social settings and more comfortable expressing themselves after completing implant treatment.

Supporting Better Speech and Daily Living

Missing teeth, particularly in the front of the mouth, can interfere with pronunciation and speech clarity. Similarly, loose or ill-fitting dentures may cause slurring or difficulty articulating certain sounds.

Because implants are securely integrated into the jawbone, they provide the stability needed for clear and natural speech. Everyday activities such as eating in public, participating in meetings, or engaging in conversations become more comfortable and predictable. These seemingly small improvements can significantly enhance daily living and social participation.

Advancements Making Treatment More Predictable

Modern implant dentistry has benefited greatly from technological innovations. Digital imaging, three-dimensional treatment planning, guided implant placement, and advanced restorative materials have improved precision and predictability. These advancements allow clinicians to tailor treatment plans to each patient's unique anatomy and functional requirements.

In addition, improved understanding of bone biology and soft tissue management has contributed to higher success rates and more aesthetically pleasing outcomes. As a result, implant therapy has become a reliable long-term solution for a wide range of patients experiencing tooth loss.

A Comprehensive Approach to Oral Health

Implant dentistry today is centred on patient outcomes rather than simply replacing missing teeth. The goal is to restore oral function, maintain facial structure, support emotional well-being, and improve overall quality of life. Successful treatment considers not only the clinical aspects of tooth replacement but also the patient's lifestyle, expectations, and long-term health needs.
