Is eating more than three meals a day bad for health?
How many meals do you have in a day? 3, 4, or 6? Yes, some dietary plans include splitting meals into six smaller meals throughout the day. Is this approach beneficial, or could it harm your health? Let's take a look at whether eating more than three meals a day is beneficial or harmful for health.
Three meals a day
Traditionally, most people follow the three-meals-a-day structure, which includes breakfast, lunch, and dinner. This structure also aligns with cultural norms and circadian rhythms. Three meals a day is a rather balanced approach to energy intake, allowing the body time to digest and rest between meals. But is this the healthiest way to eat? Eating three meals a day could be beneficial in some way, as it would take away the chance of consuming food late at night.
Late-night meals are
linked
with cardio-metabolic disease, including diabetes and heart disease. Three meals a day may also give a 12-hour window without food.
Studies
also suggest that giving our bodies at least 12 hours a day without food allows our digestive system to rest. For many, sticking to three meals simplifies the meal planning and aligns with daily schedules, and reduces the risk of mindless snacking.
This meal pattern also has its shortcomings.
'What we've been taught for many decades is that we should eat three meals a day plus snacking in between. Unfortunately, this appears to be one of the causes of obesity,' Krzysztof Czaja, an associate professor of biomedical sciences in UGA's College of Veterinary Medicine, said in a statement.
The case of eating more than three meals a day
Some dietary plans, particularly in fitness and weight-loss communities, promote eating five to six smaller meals daily. It is said to boost metabolism, stabilize blood sugar, and curb hunger. A 2017
study
found that six meals per day is better than three for blood sugar control, especially in obese people with impaired glucose tolerance (prediabetes) or full-blown type 2 diabetes.
'Our 24-week weight maintenance study showed that using a six-meal pattern instead of a three-meal pattern, while containing the same overall calories, improved blood sugar control and reduced hunger in obese people with prediabetes or full-blown diabetes.
These results suggest that increased frequency of meals, consumed at regular times, may be a useful tool for doctors treating subjects with obesity and diabetes or prediabetes, especially those who are reluctant or unsuccessful dieters," the researchers said. A 2023
review
found that a specific type of restricted eating may reduce the chances of developing Type 2 diabetes and improve your overall health.
Known as time-restricted eating, this type of fasting means having regular but fewer meals, cutting out late-night snacks, and not eating for 12 to 14 hours (often overnight).
How important is your meal timing?
Which is best?
It is important to understand that the ideal number of meals really depends on lifestyle, health goals, and individual physiology. There's no one-size-fits-all. Listening to your body matters. Whether it's three or six meals, focus on nutrient quality, portion control, and hunger cues. Eating mindfully and planning according to your lifestyle matters. Focus on whole foods, maintaining consistent eating schedules, and avoiding excessive calorie intake.

Potatoes are healthy until they are fried, here's what new US study says about french fries
Among all the vegetables, potatoes are one of the most widely consumed vegetables in the United States. An average American has a 50-pound intake of potatoes each year, claims the latest food availability data from the U.S. Agriculture Department. Yet, despite their popularity, potatoes often don't get the same nutritional recognition as vegetables like Brussels sprouts. As per Marion Nestle, a molecular biologist and emerita professor of nutrition, food studies, and public health at New York University, 'Potatoes have long been linked to poor health, even though they are essentially nutritious.' Why Potatoes are Healthy but Fries are Not? Various evidences have pointed out that it all depends on a person how they want to have an intake of potatoes. The nutrient value entirely depends on how the potato is cooked. A major study by the Harvard T.H. Chan School of Public Health, published this week in the BMJ, revealed that consuming three servings of french fries per week was linked to a consistent and slightly elevated 20% higher risk of developing Type 2 diabetes, compared to those who ate less than one serving per week. On the contrary, other potato recipes such as mashed, boiled, or baked spuds, and even chips (having corn and potato) don't link themselves to any risk factors. Relationship Between Type 2 Diabetes and Potato Consumption When earlier the research was done to find a link between potato and Type 2 diabetes, the preparation of potatoes was not kept under consideration. Seyed Mohammad Mousavi, a postdoctoral research fellow at the Harvard T.H. Chan School of Public Health and lead author of the study, said, 'the older research didn't look at how the potatoes were prepared, like fried versus boiled or baked, or what people are eating instead.' His team analyzed data from long-term cohort studies conducted over nearly 40 years, involving more than 200,000 participants who were free of Type 2 diabetes at the beginning of the research. Their findings made a point that any fried item should not be added to a person's diet regularly, despite the fact that the original form is a vegetable. However, this study doesn't mean that potatoes have to be eliminated from your diet. Potatoes 'have always been a healthy food,' said Joan Salge Blake, a clinical professor in nutrition at Boston University. 'They had some bad press, but now we know it's really just the french fry.' How Potatoes Are Healthy? Potatoes fall under the category of starchy vegetables, which means that they have a higher level of carbs in them. And, indeed, the body needs carbs for energy, and potatoes are considered a good source for it. According to Julia Zumpano, a registered dietitian at the Cleveland Clinic, potatoes are a good supply of carbohydrates, which the body requires for energy. 'Potatoes aren't totally devoid of nutrients,' said Dariush Mozaffarian, a cardiologist, public health expert, and director of the Food is Medicine Institute at Tufts University. The BMJ study, which referenced dietary questionnaires, shed light on the different types of potato preparation instead of different varieties that people might have had, including Yukon Gold, russet, and lesser-known purple potatoes. While all of them are healthy options, there are hardly a level or so of certain advantages. One such example is of sweet potatoes, which have more fiber than white, Zumpano said. Why French Fries are Harmful for Health? According to Zumpano, 'First of all, most are not freshly cut potatoes.' Those fries which are served at the restaurants are often considered as 'potato products'. However, the actual list of ingredients goes long beyond potatoes. Those fries contain ingredients such as flour, oils, colorings, and various additives. 'In a very rare case are you seeing someone slicing potatoes into wedges and putting them into a fryer.' Also, the way how fries are cooked matters. For example, were they prepared on high heat and lots of oil? If they are cooked in animal fat, like beef tallow, the additional oil raises the quantity of saturated fat and calories you consume. Additionally, when food is deep-fried at very high temperatures— On the other hand, when the food is deep-fried at extremely high temperatures, 'you induce changes in the structure of fatty acids,' Nestle explained, that this process causes a release of unhealthy compounds. The connection between Type 2 diabetes and carbohydrates, like potatoes, is important because they affect how the body absorbs glucose. When consuming refined starches of any type, 'you're getting a big burst of glucose in your bloodstream,' Mozaffarian explained. Glucose, commonly known as blood sugar, is an essential source of energy for the body. However, when elevated glucose levels persist over time, especially in individuals with a genetic predisposition, it can strain the insulin-producing cells in the pancreas, eventually leading to Type 2 diabetes. This is the reason why the American Diabetes Association recommends adding 'some' starchy vegetables to a person's diet, including potatoes, in order to get a balanced diet.

Non-invasive saliva insulin test may identify prediabetes before symptoms: Researchers
New Delhi, Aug 2 (UNI) A promising breakthrough by researchers at UBC Okanagan may soon enable easier identification of prediabetes ie individuals at risk of Type 2 diabetes, even before symptoms manifest. The study published recently in 'Applied Physiology, Nutrition, and Metabolism' highlights the potential of measuring insulin levels in saliva as a simple, non-invasive alternative to traditional blood tests, eliminating the need for needles or lab-based blood work. Dr. Jonathan Little, Professor at UBC Okanagan's School of Health and Exercise Sciences, noted that this 'spit test' could also detect early metabolic changes associated with obesity and other health risks. The research involved 94 healthy participants with varying body sizes. After fasting, each participant consumed a standardized meal-replacement shake, followed by saliva collection and a finger-prick blood glucose test. 'Individuals with obesity exhibited significantly higher saliva insulin levels compared to those who were overweight or had lower body weight, despite similar blood sugar levels,' said Dr. Little. He emphasised that saliva testing could serve as a convenient and non-invasive tool to identify people at risk of Type 2 diabetes well before symptoms appear. Type 2 diabetes currently affects around 400 million people worldwide and is conventionally diagnosed through elevated blood glucose levels. However, Dr. Little pointed out that prediabetic conditions like insulin resistance and hyperinsulinemia can develop 10 to 20 years prior to diagnosis. Early detection of hyperinsulinemia could allow timely lifestyle interventions and treatments, potentially delaying or preventing the onset of diabetes. The study's co-author, Dr. Hossein Rafiei, explained that the team aimed to develop a practical test for hyperinsulinemia using saliva. Interestingly, saliva insulin levels closely mirrored plasma insulin responses following mixed meals of varying carbohydrate content, as shown in Dr. Rafiei's earlier research at UBC Okanagan. Participants' saliva samples were collected at 30, 60, and 90 minutes after ingesting the meal-replacement shake. Notably, some individuals with lower body weight experienced significant spikes in saliva insulin post-consumption, suggesting that they might be at increased risk for Type 2 diabetes despite normal glucose levels and lean physiques. Dr. Rafiei remarked, 'The discovery that some lean individuals have high insulin levels is intriguing. This suggests saliva insulin measurement could be more informative than conventional metrics like weight or waist size.' The study also examined correlations between waist circumference, BMI, age, and sex, finding waist size to be the strongest predictor of saliva insulin levels. The researchers concluded that waist circumference may be a more reliable indicator of hyperinsulinemia than age or overall body weight when using saliva insulin tests. 'Our findings imply that saliva insulin testing might surpass blood glucose measurements in distinguishing metabolically healthy individuals from those prone to hyperinsulinemia,' said Dr. Rafiei. The study findings are significant in the context of India where prediabetes is a significant health concern, with an estimated 15.3% of the population affected. This condition, characterized by elevated blood sugar levels that are not yet high enough to be classified as type 2 diabetes, serves as a warning sign for increased diabetes cases. UNI AJ GNK

Irregular sleep may raise risk of 172 diseases—including diabetes and kidney failure
For years, health experts have warned that both too little and too much sleep could negatively affect well-being. But new research suggests the problem might not be sleep quantity alone, but how consistently and accurately people sleep. A massive seven-year study, published in Health Data Science on June 3, 2025, tracked nearly 90,000 adults using wearable fitness trackers. The findings show that irregular sleep patterns—not just total sleep time—are strongly linked to an increased risk of 172 diseases, including Parkinson's, kidney failure, and Type 2 diabetes. Many health threats may begin silently, with poor sleep at the root. Irregular sleep is more harmful than you think The study revealed that many individuals who believed they were getting eight or more hours of sleep were actually sleeping much less—sometimes under six hours a night. These 'false long sleepers' skewed earlier research that relied heavily on self-reporting. When researchers compared objective data with self-reports, the supposed dangers of sleeping 'too much' mostly disappeared, pointing instead to irregular and inconsistent sleep as the real culprit behind rising health risks. Disrupted rhythms in sleep linked to chronic conditions Researchers used UK Biobank data and accelerometers to study sleep quality, duration, fragmentation, and timing. Led by Dr. Qing Chen from China's Third Military Medical University, the team found that irregular and fragmented sleep patterns were linked to a broad array of diseases—172 in total. These included: 37% higher risk of Parkinson's disease 36% higher risk of Type 2 diabetes 22% higher risk of acute kidney failure Sleep disruption also tripled the risk of frailty in older adults and doubled the risk of developing gangrene. Over 20% of disease cases could be preventable One of the most striking findings was that optimal, consistent sleep could potentially prevent more than 20% of cases for 92 different diseases. These included not only well-known conditions like heart disease and stroke, but also lesser-known associations such as chronic obstructive pulmonary disease (COPD) and liver disorders. Sleep timing and regularity matter more than just hours While the traditional advice of sleeping 7–9 hours a night remains useful, this study emphasized that when you sleep and how consistent your schedule is may be even more important. People with erratic sleep times and inconsistent routines experienced significantly worse health outcomes—even if they logged enough total sleep hours. The researchers also identified biological markers that could explain the disease connection. Elevated levels of white blood cells and C-reactive protein were seen in participants with disrupted sleep—suggesting that chronic inflammation may be a major mechanism by which poor sleep contributes to disease. A wake-up call for healthier sleep habits Although the study is the largest of its kind, it was limited by a one-week data window and a predominantly White, healthy participant base. Yet even with these constraints, the findings held true across US-based NHANES data. The message is clear: irregular sleep can be dangerous, even if you think you're getting enough rest. Maintaining a stable sleep schedule may be a powerful, underappreciated way to protect your long-term health.
