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.

People think of menopause as just hot flashes and irregular periods, but menopause is more than that.

Perimenopause and menopause can bring a host of emotional and cognitive shifts for many women, including mood swings, anxiety, easily irritated, trouble sleeping, or having what some refer to as “brain fog.”

What Is Perimenopause?

Perimenopause is the period leading up to menopause that can last anywhere from two to eight years. This is when hormonal changes take place, especially a drop in estrogen.

These hormonal changes also impact neurotransmitters like serotonin and dopamine that are essential for mood, memory, sleep and emotional wellness.

Consequently, a woman can suffer from forgetfulness, lack of concentration, mental tiredness, low energy levels, dry skin, loss of libido and less productivity.

Brain fog can be a frustrating and overwhelming experience during menopause, particularly if a woman is juggling her career, family, ageing parents and personal obligations.

Many women suffer from anxiety symptoms, even if they have no mental health background. Hormonal changes, poor sleep and stress can exacerbate these symptoms.

But not all symptoms are due to the menopause or "normal ageing". Thyroid disorders, vitamin deficiencies, depression and other medical problems can have similar symptoms.

Therefore, if symptoms start to impact life, work, relationships or emotional wellbeing, it is important to seek medical advice and have a proper health check-up.

How To Manage It?

Management is often comprehensive, and may involve lifestyle modifications. Regular exercise, balanced nutrition, stress management and healthy sleep patterns.

In a few instances, you may additionally be suggested to take Menopausal Hormone Therapy (MHT). As more research is done and preparations of lower doses and greater safety, earlier misconceptions about hormone therapy are gradually decreasing.

Medically, women can make a difference in their quality of lives and manage menopause with greater physical, mental and emotional wellness with early recognition and timely intervention.

Besides Sunscreen, What Everyday Habits Can Help Reduce Sun Exposure And Skin Damage?

Updated Jul 18, 2026 | 11:00 PM IST

SummarySunscreen is essential, but healthy skin also depends on daily habits like moisturizing, staying hydrated, eating antioxidant-rich foods, protecting yourself with hats and clothing, maintaining gut health, and supporting skin repair.

Everyone knows that using sunscreen is one of the most important steps for protecting the skin from harmful sun rays, but dermatologists explain that it isn't the only thing you should do to keep your skin healthy. Other daily routines are also important for minimizing sun damage and maintaining healthy skin over time.

Protecting The Skin Barrier

Skin is a protective barrier for the body but constant exposure to the sun, pollution, heat and unhealthy lifestyle habits can make this barrier vulnerable.

Once the skin barrier is damaged, the skin is more susceptible to tanning, pigmentation, dryness, sun ageing and other sun damage.

Moisturising Supports Skin Health

Using a moisturiser every day is a very simple, yet effective habit. A good moisturiser is one that doesn't contain any scents and will support the barrier function of the skin, thereby preventing unwanted water loss from the skin.

Wet and plump skin is resistant to the environment and sun's rays.

Antioxidants Help Fight Sun Damage

Antioxidants are also a best practice for dermatologists. Antioxidants prevent the damage to skin cells by free radicals created by UV exposure, pollution etc.

This protection can help minimize issues like hyperpigmentation, uneven skin tone and premature ageing. Consuming foods that contain antioxidants (such as fruits, vegetables and nuts) can help keep skin healthy on the inside.

Stay Hydrated For Healthier Skin

Next, hydration is crucial. It's important to keep drinking enough water all day long to keep the skin supple and to allow the skin to repair itself. Moisture also contributes to skin's healing from environmental stress.

Physical Sun Protection Matters

Sun protection is also of great importance. Wearing hats or caps, using umbrellas, and wearing clothing that protects against the sun's rays can minimize direct exposure to the sun.

All these are simple actions that serve as a physical barrier and prevent sunburn and long term damage to the skin, particularly between 10 a.m. and 4 p.m. These simple steps provide a physical barrier and reduce the risk of sunburn and chronic skin damage, particularly in the peak hours of 10 a.m. to 4 p.m.

Gut Health And Skin Connection

Another focus has been on the connection between gut health and healthy skin, as experts recognize how crucial the role of the gut is in maintaining healthy skin.

Probiotics can potentially improve the gut-skin axis and aid in the healing process and alleviate inflammation in the body. The better the gut environment, the better the skin will be able to recover and the less the exposure to the sun will age the skin.

Collagen May Support Skin Repair

Some people can use collagen supplements as an added benefit. Collagen is involved in supporting the dermis, the skin's structural component. Keeping collagen high can help promote skin repair and healing mechanisms.

Doctors say while sunscreen is important, long-term skin protection can be achieved through a variety of healthy habits, proper nutrition, hydration and physical sun protection measures, which must be followed daily.

6 Everyday Moments When Your Eyes Work Harder Than You Realize

SummaryYour eyes work harder than you realize during everyday activities. Simple habits and regular eye care can help reduce strain and protect vision.
6 Everyday Moments When Your Eyes Work Harder Than You Realize

We tend to think of our eyes as easy – they just "see", and we go about our day. But the fact is, your eyes are adapting a lot, focusing and straining all the time, far more than you realize. Many of these moments are utterly unremarkable, but they build up gradually into a tiredness, a dryness and a long-term strain.

We see many people who are shocked to find out how hard their eyes had been working long before any symptoms appeared. Here are six common situations that deserve a whole lot more attention – and care – from your eyes.

Staring at Your Phone First Thing in the Morning

Having a quick glance at notifications before even leaving bed requires your eyes to adjust to a small, bright screen in the dark. This quick change puts a load on the eye muscles and can make them tire before your day has really started.

Long Hours in Front of a Computer

Working, studying, and hopping from meeting to meeting: extended hours in front of the screen drastically lower your usual blink rate. Less blinking equals less lubrication, which is why so many people are dry, irritated and have blurry vision by the afternoon.

Driving at Dusk or Night

Night driving is one of the most challenging visual jobs humans undertake, given low light, incoming headlights and the need to constantly change focus between the road, mirrors and dashboard. Your eyes are working tirelessly to shift between bright and dim situations in fractions of a second.

Reading Fine Print

Poorly lit restaurant menus, pharmaceutical labels, or the small text on a contract all demand that you focus hard at close range, frequently in less-than-ideal illumination. As we get older, this type of near-focus strain is very common since our natural ability to focus declines.

Switching Between Multiple Screens

Glancing from your laptop to your phone to a television and back again, it makes your eyes refocus at multiple distances. It is easier, but this continual flipping is more tiring than looking at one screen for the same period of time.

Stepping Out Into Bright Sunlight Into Bright Sunlight

Your eyes work hard to adjust while you move from a dim room into harsh daylight — or vice versa. Over time, repeated exposure to glare without the correct protection (such as sunglasses) can add unneeded strain.

None of these moments feel dramatic on their own, but together, they represent a significant daily workload for your eyes. The good news is that habits such as the 20-20-20 rule, correct lighting, regular blinking and eye check-ups can go a long way in reducing this concealed tension. We believe that awareness is the beginning of healthy eyesight.

If you are suffering frequent eye strain, dryness or fuzzy vision, it may be time to schedule a full eye exam. Your eyes work harder than you realize – let’s give them the attention they deserve.
