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.

Why Men Are at Higher Risk?

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."

Cancer Types Most Linked to Abdominal Fat

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.

What This Means for Men's Health and Cancer Prevention?

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.

How To Reduce Cancer Risk In Men?

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.

A federal judge in Massachusetts has blocked a series of vaccine policy changes introduced by U.S. Health Secretary Robert F. Kennedy Jr., dealing a significant setback to the Trump administration’s health agenda. The ruling temporarily halts new vaccine recommendations and reverses recent decisions made by the government’s vaccine advisory panel.

The decision was issued by Judge Brian Murphy of the U.S. District Court for the District of Massachusetts. It came after several medical organizations argued that the government’s actions were not based on scientific evidence and could endanger public health.

Court Says Science Was Ignored

In his ruling, Judge Murphy said vaccine policy decisions have traditionally been based on careful review of scientific data. This process is also required under federal law.

However, he wrote that the government had ignored these standards while introducing changes to vaccination guidelines. According to the court, the decisions undermined the integrity of the process that normally guides national immunization recommendations.

The ruling stops the government from implementing those changes for now. It also means the Advisory Committee on Immunization Practices, or ACIP, cannot hold its scheduled meeting this week.

Lawsuit From Medical Organizations

The case was brought by six major medical organizations, including the American Academy of Pediatrics. They claimed that the new policies changed the childhood vaccine schedule without proper scientific review.

The groups argued that the government had made “arbitrary and capricious” decisions by bypassing the usual evidence-based process. They also questioned the qualifications of several members appointed to the vaccine advisory committee.

Judge Murphy noted in his ruling that only six of the 15 committee members appeared to have meaningful experience with vaccines. The committee is responsible for recommending which vaccines Americans should receive and when.

Changes to Childhood Vaccine Schedule

The lawsuit focused on a series of policy changes introduced over the past year. These included reducing the number of diseases covered under the routine childhood immunization schedule.

In January 2026, federal officials announced a new vaccine schedule that lowered the number of diseases children are routinely vaccinated against from 17 to 11.

The changes also affected recommendations for Covid vaccines. Earlier in 2025, Kennedy announced that Covid shots would no longer be recommended for healthy children or pregnant women.

Health officials supporting the changes argued that growing mistrust of vaccines had reduced vaccination rates. They believed simplifying the schedule might rebuild public confidence.

However, critics said the changes were rushed and not supported by strong scientific review.

Experts Warn About Public Health Risks

Many doctors and public health experts strongly opposed the new policies. They warned that weakening vaccine recommendations could lead to outbreaks of preventable diseases.

Medical groups say childhood vaccination programs have been one of the most successful public health efforts in modern history. Vaccines protect children from serious diseases such as measles, polio and hepatitis B.

Several organizations also filed supporting legal documents in the case, including public health experts and research groups.

Government Likely to Appeal

Officials from the Department of Health and Human Services said the government plans to challenge the ruling. A spokesperson said the administration expects the decision to be overturned.

For now, however, the court order means previous vaccine recommendations will remain in place.

Medical organizations welcomed the ruling. They said it helps restore a science-based process that has guided vaccine policy for decades and protected the health of millions of children.

What Were The Changes Suggested In The Latest CDC Vaccine Schedule?

The federal health department sought to reduce the number of shots American children receive, announced that the new Centers for Disease Control and Prevention (CDC), vaccine schedule will include routine shots for 11 diseases for children. This is down from 17 diseases, which were earlier included. Jim O'Neill, who is the acting director of the CDC updated the agency's immunization schedule to reflect the changes, effective immediately.

The most controversial change is the narrowing of recommendations for several common childhood vaccines. Immunization against the following illnesses is now advised only for high-risk children or after consultation with a health care provider:

  • Hepatitis A
  • Hepatitis B
  • Meningococcal disease
  • Rotavirus
  • Influenza
  • Respiratory syncytial virus, or RSV

Covid-19 vaccination has also shifted to a consultation-based recommendation rather than routine use for all children.

This means shots that were once automatically given at set ages, including at birth, during infancy, and in adolescence, may now depend on individual medical discussions rather than standard guidance.

Energy Drinks Are Not A Substitute For Water In Summer, Doctors Say

Updated Mar 17, 2026 | 12:02 PM IST

SummaryHealth experts caution that choosing energy drinks over water during hot weather may do more harm than good. Excess caffeine, sugar and stimulants can increase fluid loss, strain the cardiovascular system and interfere with proper hydration.

Water remains the most reliable and effective way to keep the body hydrated during hot weather. However, many people have increasingly turned to energy drinks during long workdays or busy schedules, hoping to stay refreshed or energized.

Experts warn that relying on these drinks instead of water can create several health risks, particularly when temperatures are high.

Energy drinks are typically marketed as quick solutions for fatigue and low energy. They often contain high levels of caffeine, added sugars and stimulants that may temporarily increase alertness.

While this short term boost may seem appealing, experts say these drinks are not designed to support proper hydration. When consumed frequently, especially during summer, they can place extra strain on the body rather than helping it stay cool and hydrated.

Dr Arun Sachdeva, an Internal Medicine Specialist at Felix Healthcare in Bengaluru, explains that replacing water with energy drinks during hot weather can interfere with the body’s natural hydration balance.

According to him, excessive consumption of these beverages may contribute to both immediate and long term health concerns, particularly when the body is already losing fluids through sweating.

Higher Risk Of Dehydration

One of the main concerns with energy drinks is their caffeine content. Caffeine acts as a mild diuretic, which means it can increase urine production and lead to faster fluid loss from the body.

During summer, when sweating already causes significant water loss, this effect may make it harder for the body to maintain proper hydration.

When energy drinks replace water intake, the risk of dehydration increases. Common symptoms of dehydration include fatigue, dizziness, headaches and dry mouth. In more severe cases, dehydration can also affect concentration, physical performance and overall wellbeing.

Excessive Stress On The Heart

Another concern is the combination of caffeine and other stimulants commonly found in energy drinks. These ingredients can raise heart rate and increase blood pressure. Regular consumption, especially in hot weather, may place additional strain on the cardiovascular system.

For people who already have high blood pressure or existing heart conditions, excessive intake of energy drinks could increase the risk of heart palpitations or irregular heart rhythms. Experts therefore recommend limiting the consumption of these beverages, particularly during periods of intense heat.

High Sugar And Empty Calories

Many energy drinks available in the market contain large amounts of added sugar. Drinking them regularly instead of water can significantly increase daily calorie intake without providing meaningful nutritional value.

Frequent spikes in blood sugar levels may gradually increase the risk of metabolic disorders. Over time, consistently high sugar consumption can contribute to health problems such as obesity and type 2 diabetes.

Therefore, doctors advise paying attention to sugar content in beverages, especially during hot weather when people tend to drink more fluids throughout the day.

Sleep Disruption And Energy Crashes

Although energy drinks are commonly used to combat tiredness, their high caffeine content can disrupt normal sleep cycles if consumed frequently. Poor sleep can lead to persistent fatigue, irritability and reduced concentration.

Instead of providing sustained energy, regular consumption of energy drinks may lead to temporary stimulation followed by sudden drops in energy levels.

This cycle can leave individuals feeling even more tired later in the day, creating a pattern where they rely on more caffeinated drinks to stay alert.

Kidney Health And Hydration

Proper hydration plays an important role in maintaining kidney health. Water helps the kidneys filter waste products and maintain fluid balance within the body. Energy drinks do not provide the same hydration benefits when they replace water intake.

When the body does not receive enough water, the kidneys may struggle to function efficiently. Over time, poor hydration can increase the risk of kidney related problems and may affect the body’s ability to regulate fluid levels effectively.

Why Water Remains The Best Choice

Doctors emphasize that water remains the safest and most effective drink for maintaining hydration during summer. It helps regulate body temperature, supports organ function and replaces fluids lost through sweating without introducing excess caffeine, sugar or stimulants.

Energy drinks may occasionally provide a quick boost of alertness, but they should not be used as a substitute for water. Maintaining regular water intake throughout the day remains one of the simplest and most effective ways to support overall health during hot weather.

Your Work Life Habits Can Affect Kidney Health, Doctors Say

Updated Mar 16, 2026 | 06:10 PM IST

SummaryExperts explain how sedentary lifestyles, high-salt convenience foods, irregular sleep and poor hydration can contribute to early signs of kidney stress even in individuals without traditional risk factors such as diabetes or smoking.
Doctors Warn Modern Work Habits Could Be Affecting Kidney Health

Late nights at the office, quick dinners made from instant noodles or packaged snacks and constant deadline pressure are often treated as normal parts of professional life, but doctors say these habits may gradually affect kidney health.

Nephrologists report that routine health screenings are increasingly detecting early signs of kidney stress in people in their late 20s to 30s, even among those without traditional risk factors such as diabetes, smoking or a family history of kidney disease.

According to nephrologist Dr Kristin George, some patients show warning indicators such as elevated creatinine levels, high blood pressure or traces of protein in the urine.

Creatinine is a waste product filtered out by the kidneys and rising levels may indicate that the organs are not removing waste as efficiently as they should.

Doctors say that when lifestyle patterns are examined more closely, prolonged work stress, sedentary routines, irregular meals and frequent late-night snacking often emerge as common factors.

Kidney Disease Is A Growing Global Concern

Kidney disease is already recognized as a major global health challenge. Recent research estimates that nearly 850 million people worldwide are living with some form of kidney disease.

Chronic kidney disease, or CKD, involves the gradual loss of kidney function over time and can eventually lead to kidney failure if it is not detected early.

Health experts warn that CKD could become one of the leading causes of death globally in the coming decades. Diabetes and hypertension account for a large proportion of cases and according to the International Society of Nephrology these two conditions combined contribute to nearly two-thirds of chronic kidney disease cases worldwide.

Doctors also note that prolonged stress may indirectly increase these risks because long-term elevations in stress hormones such as cortisol can raise blood pressure and disrupt metabolic balance.

Processed Foods And Late-Night Eating

Dietary habits may also contribute to kidney strain, particularly when busy schedules encourage reliance on convenient foods that are often high in sodium and low in nutritional value.

Late-night meals frequently include instant noodles, chips, processed meats or packaged snacks, many of which contain significant amounts of sodium.

Sodium helps regulate fluid balance, but excessive intake forces the kidneys to work harder to maintain stable blood pressure. The World Health Organization estimates that most adults consume nearly twice the recommended daily sodium intake, largely because of processed foods.

Doctors say that consistently high salt intake can gradually increase blood pressure and place additional strain on kidney function.

Sedentary Work And Poor Hydration

Hydration habits and prolonged sitting are additional concerns among office workers. Many professionals rely heavily on coffee, energy drinks or sugary beverages during long workdays, often replacing plain water as the main source of fluid intake.

While moderate caffeine consumption is generally considered safe, relying mainly on caffeinated drinks can contribute to mild dehydration, which may affect blood circulation through the kidneys and increase the likelihood of kidney stones.

At the same time, many corporate jobs require employees to remain seated for extended periods. Sedentary routines have been linked to obesity, impaired glucose metabolism and high blood pressure, all of which are major contributors to kidney disease.

Early Signs Often Go Unnoticed

Kidney disease often develops silently in its early stages, which means many people remain unaware of the problem until significant damage has occurred.

Early kidney dysfunction may progress quietly for years before symptoms appear, and by the time signs such as swelling, fatigue or changes in urination become noticeable, kidney function may already be reduced.

Doctors therefore recommend periodic screening tests, including serum creatinine measurements, estimated glomerular filtration rate (eGFR) tests and urine albumin tests, which can detect early signs of kidney damage.

Small Changes Can Make A Difference

Health experts say that protecting kidney health often begins with small lifestyle changes. Reducing processed food consumption, limiting excessive salt intake, staying adequately hydrated and maintaining regular sleep schedules can all support kidney function.

Taking short movement breaks during long work hours and managing stress through regular physical activity or relaxation techniques may also help reduce the long-term strain that modern work routines place on the body.

Doctors emphasise that kidney disease usually develops gradually, which means recognising and adjusting everyday habits early may help many young professionals protect their kidney health.
