When was the last time you measured your waistline? If you assume that BMI is the only number to focus on when it comes to your health, think twice. New research has revealed a shocking revelation—your waist circumference might be a far better predictor of men's cancer risk than BMI.
The study finds that for each 4-inch increase in waist size, a man's risk of cancer increases by a staggering 25%. Meanwhile, BMI, commonly regarded as the gold standard for assessing obesity, raises cancer risk by only 19% for the same weight gain. So, if you've been dismissing that pesky belly fat, it's time to take notice.
But why is your waistline so important? The reason is visceral fat—the hidden, deep fat that accumulates around your organs. Unlike other body fat, visceral fat is a stealthy troublemaker, causing inflammation, insulin resistance, and abnormal blood fat levels—all of which combine to create a cancer-perfect storm.
Obesity has been associated with an increased risk of numerous health conditions, including cancer, for decades. The research, though, indicates that a specific measure of the body—waist circumference—may be an even more reliable forecaster of cancer risk in men than the more frequently employed Body Mass Index (BMI). This finding emphasizes the need to pay particular attention to the distribution of fat and not merely to the weight of the body.
BMI has been the go-to measure for years for gauging health risks related to obesity. New research, though, that appears in The Journal of the National Cancer Institute indicates that waist measurement is a better predictor of cancer risk in men. According to the research, four more inches (10 cm) around the waist will add 25% to a man's cancer risk. Conversely, a 3.7 kg/m² rise in BMI (from a BMI of 24 to 27.7) increased cancer risk by only 19%.
Why is waist circumference a better predictor, then? Unlike BMI, which measures weight relative to height, waist circumference actually measures abdominal fat—specifically, visceral fat. This type of fat encircles internal organs and is also linked to higher levels of inflammation, insulin resistance, and abnormal blood lipids, all of which are factors in cancer growth. BMI, however, does not measure fat distribution, so two individuals with the same BMI can have very different levels of health risk depending on where fat is deposited on their bodies.
Interestingly, the research identified a significant difference between men and women when it came to waist circumference and cancer risk. Although waist circumference and BMI were linked with obesity-related cancers in women, the relationship was weaker than for men. An increase of 12 cm (4.7 inches) in waist size or a 4.3 rise in BMI (from 24 to 28.3) raised the cancer risk in women by just 13%—a much lower percentage than for men.
Experts credit this difference to the way that fat is stored in the body. Men are more likely to carry fat around the abdomen, especially as visceral fat, which is more metabolically active and associated with cancer-producing biological alterations. Women, by contrast, store fat in peripheral sites such as the hips and thighs, where it is less likely to drive systemic inflammation and metabolic disturbances.
A possible reason is that men tend to depot fat more in the visceral regions, whereas women tend to carry more subcutaneous and peripheral fat," wrote the researchers. "This may render waist circumference a more robust risk factor for cancer in men and account for why waist circumference provides additional risk information beyond BMI in men but not women."
The research used the International Agency for Research on Cancer (IARC) data to define obesity-related cancers. These cancers are esophageal (adenocarcinoma), gastric (cardia), colorectal, rectal, liver, gallbladder, pancreatic, renal, and thyroid cancers, and multiple myeloma and meningioma. In men, abdominal obesity is especially significant in raising the risk of these cancers through high levels of insulin and markers of inflammation.
For women, the research proposes that both waist circumference and hip circumference may give a more accurate estimate of visceral fat and cancer risk. "Adding hip circumference to risk models could strengthen the link between waist circumference and cancer, especially in women," researchers observed.
With these results, doctors advise men to be more mindful of their waistline than only their BMI. Waist size is an easy method to gauge health risk, and its maintenance through lifestyle changes might be the key to cancer prevention.
Track Your Waist Size: Regularly measure your waist circumference and try to keep it in a healthy range (below 40 inches for men, according to medical advice).
Eat a Balanced Diet: A diet containing high fiber, lean protein, and healthy fats can assist in limiting visceral fat gain.
Exercise Consistently: Regular exercise with a combination of aerobic and strength training will help maintain a healthy waistline.
Control Stress and Sleep: Persistent stress and inadequate sleep tend to cause weight gain, especially in the midsection of the body.
Regular Health Screenings: Early identification of cancer risk factors through regular screening can greatly enhance long-term health status.

Naturopath and health educator Barbara O'Neill believes many of the foundations of good health are simple, inexpensive, and often overlooked.
In an interview with HealthandMe, she spoke about her journey into natural healing. Barbara said her interest began when she was looking for alternatives to repeated medication use for her children.
"I was pulled towards natural healing because I didn't want to give my children drugs," she said, recalling how her first child underwent four courses of antibiotics within six weeks.
That experience prompted her to explore other ways of managing common health issues such as earaches and discomfort.
Barbara said she sees similarities between her philosophy of health and Ayurveda. "I believe that there's a lot of similarities between what I believe," said the 72-year-old, adding that she supports approaches that work and do not cause harm.
While acknowledging that medicines can save lives in emergencies, she argued that long-term healing depends on creating the right conditions for the body.
"Yes, in a crisis, a drug may save a life, but drugs can't heal us. That's why it's time to go back to the old ways," she said.
According to Barbara, understanding how the body functions is key to understanding healing.
"When you understand how they function, then you begin to understand what they need. And if you give the body the right conditions, the healing will accelerate," she told HealthandMe.
Barbara said that sleep, hydration, exercise, and natural foods are key to better health. She also called out modern lifestyles, which often encourage people to stay awake too late, particularly because of technology; and recommended getting enough sleep.
"Start going to bed earlier and aiming for eight hours sleep a night," she said.
Barbara also emphasized daily movement, whether through running, walking, push-ups, squats, or stretching.
"Every day, I make a point of moving my body," she said.
At a time when supplements have become a multi-billion-dollar industry, Barbara revealed that she does not take any supplements herself.
"I take no supplements," she said, noting that she advocates focusing on fundamental health habits.
"What should be there instead is exercise every day, eating food in its natural state, drinking adequate water, and going to bed early," she said.
While she is not opposed to supplements, she believes they are often unnecessary.
"There are times where they may be necessary, but most of the time we don't need them," she added.
Barbara also encouraged people to eat foods in their natural state and suggested a simple dietary habit for Indians.
"Eat dal every day," she said.
For stress management, she said both sleep and meditation are important. She described beginning each day with prayer, reflection, and quiet time.
Barbara said that the human body has an innate ability to heal when supported by healthy habits.
"I want people to remember that they live in a body that can heal. So please look after it," she told HealthandMe.
Stress and long working hours can worsen preeclampsia in women. (Photo credit: AI generated)
Many working women who are pregnant tend to dismiss signs such as headaches, swelling, or vision changes, thinking that they are common during pregnancy. However, these issues can be caused by preeclampsia, a serious condition that requires timely attention, especially among busy working women.
Dr Prachi Sarin Sethi, Senior Consultant – Obstetrician, Gynaecologist & Laparoscopic Surgeon, Motherhood Hospitals, Gurgaon, said, "Pregnancy comes with many physical changes, and it is common for women to experience discomfort such as swelling, fatigue, or headaches. However, sometimes these symptoms may point to something more serious, namely preeclampsia, a pregnancy-related condition that can affect both the mother and baby. Working women tend to ignore the signs of this condition and struggle in silence. Preeclampsia is a condition that usually develops after the 20th week of pregnancy. It is mainly characterised by high blood pressure and can affect organs such as the liver and kidneys. If not managed in time, it can lead to serious complications for both mother and baby."
The exact cause of preeclampsia is not known. Certain factors increase the risk, including:
Many symptoms of preeclampsia are mistaken for normal pregnancy changes. These include:
Working women may ignore these signs due to work pressure, long hours, or frequent travel, assuming they are just tired or stressed. If left untreated, preeclampsia can lead to serious complications such as:
Early detection and proper care can help manage the condition and reduce risks.
This is why working women miss the signs
In today’s fast-paced lifestyle, many women continue working through pregnancy without slowing down. Long working hours, stress, irregular meals, and lack of rest tend to worsen symptoms. Many women delay check-ups or ignore warning signs, thinking they are minor issues.
Report any signs and symptoms, such as headaches and vision changes, to a doctor. De-stress by practising yoga and meditation. Monitor blood pressure regularly, avoid overexertion, and maintain a balanced diet consisting of fresh fruits, vegetables, whole grains, and pulses. Avoid junk, oily, and canned foods. It is also necessary to stay hydrated, attend regular health check-ups, and follow-up appointments.

Osteoarthritis (OA), long considered a “wear-and-tear” disease of old age, is increasingly being diagnosed in people as young as 30, according to new research.
The review by researchers at Indraprastha Apollo Hospitals suggests OA should be viewed as a heterogeneous syndrome rather than a single disease. The condition is driven by a combination of biological, biomechanical, metabolic, genetic, and molecular factors, but in youth obesity and poor lifestyle is surging the cases.
“Osteoarthritis is no longer confined to the elderly — we are now seeing patients as young as 30, often driven by obesity and sedentary lifestyles. This research makes clear that osteoarthritis is not a single disease but a spectrum of conditions,” said Dr. (Prof.) Raju Vaishya, Senior Consultant Orthopaedic and Joint Replacement Surgeon, Indraprastha Apollo Hospitals.
Noting that a one-size-fits-all approach may not help, the expert stressed the need for personalized treatment that recognizes the specific phenotype in each patient.

The review, published in International Orthopaedics, identifies six disease subtypes, including inflammatory, metabolic, and pain-sensitization variants. Researchers recommend MRI-based tools and biomarker panels to guide treatment decisions.
Emerging technologies such as AI-assisted MRI scoring and PET-MRI with 18F-NaF may also enable earlier detection and better patient classification, although wider clinical adoption will require standardized protocols and large-scale validation studies.
More than 500 million people worldwide live with osteoarthritis, accounting for 7.6 per cent of the global population. According to Global Burden of Disease estimates, prevalence has increased by 132 per cent over the past 30 years and is projected to rise by another 60 per cent by 2050.
Women, people with obesity, and those with previous joint injuries are disproportionately affected.

Osteoarthritis occurs when the cartilage that cushions the ends of bones gradually wears down, causing joints to become stiff, painful, and less mobile.
The disease commonly affects the knees, hips, and small joints of the hands, although it can occur in almost any joint.
Common symptoms include:
Experts say maintaining a healthy weight, staying physically active, avoiding prolonged sedentary behaviour, and preventing joint injuries can help lower the risk of osteoarthritis.
One of the biggest challenges in osteoarthritis treatment is the “care gap.” Many patients are too young or not yet severe enough for surgery but may spend years relying on medications that relieve symptoms without addressing the underlying mechanics of joint stress.
Research suggest gait retraining — adjusting the way a person walks — could help bridge this gap. Unlike medication or surgery, gait retraining is non-invasive and may offer a sustainable long-term solution.
Currently, gait retraining often requires specialized tools such as motion-capture systems and pressure-sensitive treadmills. However, newer approaches, including smartphone-based video analysis and sensor-equipped “smart shoes,” are being developed to make the technique more accessible.
Experts caution against making major changes to walking patterns without professional guidance, as improper adjustments may place additional strain on other parts of the body.
