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.

Blood tests are often a source of dread for people in our society. While many people dread the needle stick, most are scared of what the results may show. Even before consulting a physician, most people nowadays would consult an AI-powered platform to verify and interpret the values of their blood tests. However, such online searches most often give rise to more uncertainties and confusion rather than answering the basic queries. Thus, this article is an attempt to shed some light on the basics of common blood test results.
Lipid profile is one test that everyone should do, at least occasionally, after the age of 40. This is a silent epidemic, and without blood tests, no clinical symptoms can reliably identify raised lipid parameters. There are multiple parameters printed in the report, but the main values we are looking for are total Cholesterol, triglycerides, LDL, and HDL. There are many others, but the interpretation of those is best left to your physician. Total Cholesterol should be less than 200, triglycerides less than 150, and the “bad” cholesterol, or LDL, should be below 100. On the other hand, HDL, the “good” cholesterol, should be above 40 for men and above 50 for women. So, for HDL, we want the values to be higher! However, whether deranged lipid parameters warrant treatment and, if so, for how long, will be the clinical decision of your doctor.
CBC means complete blood count. This is the most basic test done for every patient. In this test, we check for levels of haemoglobin, total leukocyte count, differential white cell count, platelet count, and ESR. Besides, there are numerous other parameters printed in your report, like MCV, MCH, MCHC, RDW, and PDW. But let’s first look at the basic parameters. Haemoglobin is perhaps the most important parameter to look at. It shows how much oxygen your blood can carry. Low hemoglobin is called anemia. If you have anaemia, you need to get treatment ASAP. The standard normal values of hemoglobin depend on age and gender and also physical states like pregnancy. The normal hemoglobin of an adult male will be different from that of an adolescent girl. There are many different causes of anaemia in our society, like iron deficiency, worm infestation, thalassemia, and kidney disease. Your doctor will do further tests to elucidate the cause.
The next most important parameter is total leukocyte count. This gives an indication of whether you have any infection or inflammation. Conversely, in some conditions like Typhoid, the counts may be low despite fulminant infection. Platelet count is also important in infections like dengue, where it may get dangerously low. We need to check platelet count repeatedly, sometimes even twice or thrice the same day, in dengue infection. Platelet count may be low in some forms of blood cancer too.
The other parameters like MCV and RDW are too complex to be discussed in this short article. Suffice it to say, they are deranged in conditions like Thalassemia, sickle cell disease, vitamin B12 deficiency, and hereditary Red cell membrane disorders.

And finally, the ESR is a very non-specific parameter. It can be raised in multiple conditions, ranging from cancer to inflammation. It is usually interpreted in unison with other necessary tests.

“All That” star Christy Knowings has died after reportedly suffering an asthma attack that led to cardiac arrest and brain damage.
The 46-year-old actress was hospitalized on August 7 after the attack and placed on life support, TMZ reported.
According to TMZ, citing family sources, Knowings suffered cardiac arrest following the asthma attack. Her family decided to take her off life support on August 11.
Knowings, who was born on February 25, 1980, in the Bronx, is the second former All That cast member to die this year, following the fatal hit-and-run death of Kianna Underwood in January in Brooklyn.
In a Facebook post, Knowings’ aunt wrote that her niece was an “outstanding actress, comedian, twin sister” and an “amazing daughter.”
Knowings’ reported death after complications from an asthma attack is a reminder that while asthma can often be managed, it should not be taken lightly, health experts told HealthandMe.
Dr. Abhijit Ahuja, Consultant Pulmonologist, Saifee Hospital, Mumbai, explained that asthma is a condition that makes it difficult to breathe because the airways become inflamed and narrow.
Many people with asthma can control their symptoms with medication. However, an asthma attack can sometimes become severe and life-threatening.
During an asthma attack, symptoms suddenly worsen and usual medication may not provide enough relief. A person may experience difficulty breathing, wheezing, chest tightness, severe coughing or trouble speaking.
“If you use your inhaler but still have trouble breathing, you need to go to the hospital right away,” Dr Ahuja said.
When the airways become so narrowed that the body does not receive enough oxygen, the asthma attack can turn severe. The lungs may also be unable to remove carbon dioxide properly.
“If this keeps happening, it can hurt parts of the body like the brain and the heart,” Dr Ahuja said.
A severe asthma attack can lead to difficulty breathing, loss of consciousness, brain injury and cardiac arrest.
Dr. Taniya Mehta, Consultant Respiratory Medicine, Sterling Hospitals, Gujarat, told HealthandMe that while most asthma attacks can be treated, a very severe attack can become deadly when the airways become so tight that the lungs cannot get enough oxygen.
“If treatment isn't given quickly, low oxygen levels can cause the lungs to stop working, damage the brain, cause the heart to stop and lead to death,” she said.
Seek emergency medical help if a person has:
People may be at greater risk if they:
Deadly asthma attacks are uncommon, but they can happen quickly, the doctors warned.
Taking asthma medication as prescribed, knowing how to use inhalers correctly, attending follow-up appointments and undergoing lung tests when needed can help keep asthma under control.

Walking past a bakery and suddenly craving a pastry, even though you’re not physically hungry.
Seeing an ad for your favorite pizza while watching TV and suddenly thinking about ordering it, even though you’ve just had dinner.
Do you experience this too? This is often referred to as “food noise”—persistent cravings, thoughts or mental chatter about food that can occur even when you’re not physically hungry.
A 2025 study published in Nutrients found that 57% of people with obesity reported experiencing food noise.
Constant exposure to food cues—from social media posts and advertisements to food-delivery apps and supermarket aisles—can further fuel these cravings.
While thinking about food is a natural part of everyday life, for some people living with obesity, these thoughts can become persistent and difficult to escape. This may contribute to overeating and, over time, make weight and metabolic health harder to manage.
HealthandMe spoke to Dr. Jasjeet S Wasir, Bariatric & Metabolic Physician, Director, Medanta – The Medicity, to understand the mechanism behind food noise.
“Food noise is like having a notification pinging on your phone every few minutes. You can ignore it a few times, but eventually the constant pinging wears down your attention and willpower, and you give in to it and indulge,” Dr. Jasjeet said.
A more formal, non-medical definition of food noise is persistent, intrusive thoughts about food, such as cravings, mental “chatter” about what to eat next, or a preoccupation with eating that some people experience throughout the day, seemingly independent of actual hunger.
Normal hunger, or the “hunger of the body”, occurs when the body needs food and the brain responds to that need. Once adequate nutrition and calories have been consumed, appetite is influenced by satiety signals and hormones such as leptin, GLP-1 and insulin.
With food noise, however, thoughts about eating can persist even when a person is not physically hungry.
The biology behind food noise is not necessarily a primary defect in the physiological hunger system, but may involve overactivation of the reward system. This system influences mood, motivation, pleasure and cravings and can be activated by food-related cues such as sight, smell and memory, Dr. Jasjeet said.
Common situations in which people may experience heightened food noise include:
Dr. Jasjeet said that "there is no direct or linear correlation between prediabetes and food noise. The relationship is more complex, and it can be difficult to determine which comes first".
In a healthy state, insulin acts on appetite centers in the brain and helps suppress hunger. Prediabetes, in most cases, involves insulin resistance. Insulin resistance in the brain may alter this appetite-suppression effect and potentially contribute to persistent food-related thoughts.
At the same time, prediabetes, excess weight and increased cravings can share common underlying factors, including insulin resistance, inadequate sleep, stress, dietary patterns, genetics and the food environment.
"Food noise becomes important when thoughts about food begin to influence everyday eating behavior—for example, when a person repeatedly eats without physical hunger or finds it difficult to stop thinking about food," the expert said.
If persistent food-related thoughts contribute to excess energy intake and weight gain, they may adversely affect metabolic health and perpetuate insulin resistance. Over time, this can increase the risk of complications such as type 2 diabetes.
However, the doctor said that food noise is not a symptom or diagnostic marker of prediabetes. Prediabetes needs to be identified through appropriate blood glucose tests.
Dr. Manjunath Malige, Director, Endocrinologist, Diabetologist, Obesity & Weight Management Specialist, Sakra World Hospital, Bengaluru, told HealthandMe that people with prediabetes usually have some degree of insulin resistance, but insulin resistance alone cannot be said to cause food noise.
Appetite and eating behavior are complex and influenced by biological signals, brain reward pathways, environmental food cues, sleep, stress and learned behaviors.
In India, where diets can sometimes be carbohydrate-heavy and low in protein or fiber, some people may experience greater fluctuations in hunger and cravings. When this constant chatter around food becomes excessive, it can take up significant mental space. If it leads to frequent snacking or overeating, it can make weight and blood glucose management more challenging.
Dr. Jasjeet said the first step is not to fight food or impose extreme restrictions, but to understand what is driving the urge to eat.
The doctor noted that ask yourself: Is it genuine hunger, or are you eating because of stress, boredom, habit or simply because food is available?
Having structured, balanced meals with adequate protein, vegetables, fiber and healthy fats can improve satiety. Excessive restriction or skipping meals can sometimes make cravings worse.
Other important factors include:
Most importantly, the experts noted that the goal is not to never think about food, as food is an important part of our lives and culture. The concern is when these thoughts become intrusive, distressing or start controlling eating behavior. In such cases, it is important to seek professional guidance.
