A new peer-reviewed study is raising fresh questions about the effectiveness of displaying calorie counts on restaurant menus and food labels—an increasingly common sight in Thailand’s urban eateries and supermarkets. While these numbers are meant to encourage healthier eating, the latest research indicates they might have the opposite effect, leaving consumers more confused and less confident about their food choices.

Published recently in the Journal of Retailing, this study involved over 2,000 participants across nine experiments. According to the research team led by academics specializing in health behavior and consumer psychology, when people considered calorie information while judging food, they unexpectedly rated unhealthy foods as less bad and healthy foods as less beneficial. Even more striking, participants became less certain in their assessments after seeing calorie numbers, with their healthiness ratings on foods like salads and cheeseburgers converging closer together. Those who did not see calorie data could clearly distinguish between healthy and unhealthy foods, but calorie counts appeared to muddy these distinctions (The Conversation).

A new analysis by a California-based nutritionist has reignited global debate about rising obesity rates, highlighting how changes in food habits, physical activity, and daily routines have reshaped public health since the 1960s. With obesity affecting 43% of Americans in 2024—more than triple the 13% rate recorded in the 1960s—the findings resonate well beyond the United States, including among Thais increasingly exposed to Western fast food, sedentary lifestyles, and evolving sleep habits. The nutritionist’s insights, summarised from recent media interviews and supported by scholarly research, remind us that slimming secrets from the past could offer crucial lessons for preventing modern health crises in Thailand and across the globe (Daily Mail).

A recent US report reveals that ultra-processed foods now account for 60% of American diets, raising urgent questions about the health costs of convenience and what this trend may signal for Thai consumers (WRAL). As Thailand’s urban lifestyles evolve and Western-style diets gain popularity, Thai health experts warn the nation may be following a similar—and troubling—trajectory.

Ultra-processed foods, often packaged for convenience, include items like sweetened breakfast cereals, instant noodles, reconstituted meat products, and sugary drinks. These foods are typically high in refined sugars, unhealthy fats, salt, and artificial additives, while being low in fiber, vitamins, and minerals (Harvard T.H. Chan School of Public Health). The sheer scale observed in the US—where more than half of daily caloric intake comes from such products—has serious implications for public health: studies consistently link diets high in ultra-processed foods to increased rates of obesity, diabetes, cardiovascular disease, and even some cancers (BMJ).

A new scientific study has revealed that simply restricting carbohydrate intake twice a week—rather than severely cutting calories through intermittent fasting—can offer similar improvements in metabolic health. This finding promises a potentially more sustainable and accessible route for people in Thailand and worldwide seeking the metabolic advantages typically associated with intermittent fasting, but who struggle with its more stringent regimens. The research, published on May 11, 2025, provides fresh insights into how diet modification can contribute to better heart and metabolic function without the challenges of strict calorie deprivation (ScienceAlert).

A wave of cutting-edge scientific research has triggered global alarm bells over the dangers of sugar, with health experts comparing its addictiveness and health impact to those of nicotine and even cocaine. As new findings highlight the biochemical and psychological hold of sugar on the brain, Thailand is both a consumer and battleground, taking concrete policy steps to help curb this ‘sweet danger’ before it causes a wider epidemic of obesity, diabetes, and mental health disorders.

A groundbreaking new study suggests that restricting carbohydrates just two days a week may provide the same metabolic health benefits as the more challenging intermittent fasting diets, offering hope for simpler approaches to improving heart and metabolic health. These findings could open new doors for Thai readers eager to enhance their health but daunted by the demanding routines of traditional fasting regimens.

Intermittent fasting — especially the popular “5:2” version, where people drastically reduce calorie intake on two days each week — has won devotees around the world, including in Thailand, for its reputation as a weight loss tool with additional metabolic perks. However, many Thais and others have struggled to stick with fasting due to hunger pangs, meal disruption, or concerns about nutritional adequacy. The latest research, led by an Associate Professor of Nutrition at the University of Surrey and published on May 11, 2025, in The Conversation, offers a gentler alternative: twice-a-week carbohydrate (not calorie) restriction may deliver similar health benefits without forcing people to go extremely hungry or disrupt their regular eating habits, according to their study outlined on ScienceAlert.

A recent international study has revealed that higher concentrations of caffeine in the blood may help reduce body fat and lower the risk of developing type 2 diabetes, sparking fresh debate about caffeine’s broader health effects for Thais and coffee lovers worldwide. The findings, published in BMJ Medicine and involving researchers from the Karolinska Institute in Sweden, University of Bristol, and Imperial College London, point to new possibilities for managing obesity and diabetes—two major public health challenges in Thailand—by leveraging something as simple as a cup of coffee.

A new survey from the Pew Research Center reveals a complex portrait of American eating habits in 2025, highlighting how escalating food prices and evolving lifestyles are making healthy eating more challenging for many. This comprehensive analysis sheds light on the balance between taste, convenience, affordability, and healthiness, revealing key insights that resonate even for readers in Thailand navigating their own nutrition landscapes.

As the cost of food continues upward, 90% of surveyed US adults acknowledge that healthy food has become more expensive in recent years. Nearly seven in ten say these price increases make it more difficult to maintain a healthy diet, with lower-income individuals feeling the pinch most acutely. The survey, conducted among 5,123 adults, captures shifting priorities and the struggle to eat healthy in a world saturated by rising obesity, proliferating food delivery options, and ever-changing dietary advice from social media influencers (pewresearch.org).

Aspartame, the popular calorie-free artificial sweetener featured in thousands of food and drink products across Thailand and the globe, is under renewed scrutiny after recent research highlighted its potential health risks despite decades of widespread use. While aspartame has long been promoted as a guilt-free alternative to sugar—especially for those managing weight or diabetes—nutrition experts caution that its effects may not be entirely benign, prompting Thai consumers to reconsider their dietary choices in light of emerging evidence.

A groundbreaking study by researchers at Japan’s Fujita Health University has uncovered an unexpected role for brain-derived estrogen in directly regulating appetite and body weight, upending traditional beliefs about how hormones shape our eating habits. Their findings, recently published in The FEBS Journal, not only broaden our scientific understanding but could also open new avenues for treating obesity and overeating—issues of increasing significance in Thailand and around the world (PsyPost).

A groundbreaking clinical trial has revealed that semaglutide, a drug already in use for managing diabetes and obesity, is poised to transform treatment for a widespread and potentially deadly liver condition known as nonalcoholic steatohepatitis (NASH). This discovery is seen as a potential game-changer in the medical field, offering hope to millions of patients in Thailand and worldwide who currently face limited therapeutic options for this silent, progressive disease.

NASH is a severe type of nonalcoholic fatty liver disease (NAFLD) characterized by liver inflammation, fat buildup, and tissue damage not caused by alcohol. If untreated, NASH can progress to cirrhosis, liver cancer, and even lead to liver failure requiring transplantation. In Thailand, the prevalence of NAFLD, which often precedes NASH, is climbing in parallel with rising rates of obesity and type 2 diabetes, mirroring a global pattern seen in recent years (biomedcentral.com, pubmed.ncbi.nlm.nih.gov). The latest study, as reported by ScienceAlert, demonstrates that semaglutide can lead to marked improvements in liver health and may soon provide a much-needed treatment option for millions.

A wave of new research is challenging the long-held supremacy of traditional cardio workouts for weight loss, pointing instead to the power of metabolic conditioning, or “metcon,” as a more efficient and effective method. Recent studies show that metabolic conditioning, which blends high-intensity intervals with strength-based movements and minimal rest, can lead to greater fat loss, improved cardiovascular health, and preserved muscle mass compared to classic steady-state cardio routines such as jogging or cycling (Women’s Health; Inspire Fitness; Signos).

The debate around the most effective exercise for weight loss—walking for a longer duration or jogging for a shorter time—is especially relevant for people beginning their fitness journey. Recent research and expert opinions highlight unique advantages for both activities, but choosing “the best” depends on individual health status, goals, and the ability to maintain an exercise habit over time. For Thailand, where exercise habits are intertwined with climatic, societal, and even urban design considerations, understanding these differences is key for effective weight management and health promotion.

A new debate making waves among fitness enthusiasts is whether 45 minutes of brisk walking can rival 15 minutes of slow jogging when it comes to losing weight. Recent research and expert analysis suggest that both forms of exercise can be effective, but the best choice may ultimately depend on personal health goals, fitness levels, and lifestyle.

As Thailand’s population faces mounting challenges from sedentary lifestyles, rising rates of obesity, and related metabolic disorders, understanding the pros and cons of different exercise routines is not just a matter of fad-following—it’s crucial public health knowledge. Walking and jogging are both popular among Thais of all ages due to their accessibility: urban parks, temple grounds, and riverside walkways bustle with morning and evening exercisers. Knowing which activity yields better results for weight loss helps Thais make informed choices for their health.

A growing body of research and expert opinion is highlighting a silent yet serious consequence of excessive abdominal fat in men: a dramatic impact on hormonal balance, sexual health, and fertility. As obesity rates continue to rise—across the world and notably in Asian countries including Thailand—doctors are warning that belly fat is much more than a cosmetic concern. Landmark findings discussed by leading endocrinologists reveal that fat surrounding the waistline acts as an endocrine organ, disrupting testosterone levels and overall male vitality (The News).

Popular health trends recently have seen a surge in interest in so-called “cortisol bellies” and “cortisol faces,” fueled by viral social media posts and a spike in online searches for cortisol-related health advice. These buzzwords, while catchy, attempt to simplify the highly complex biological processes behind how our bodies respond to chronic stress—sometimes sparking unnecessary worry among Thai and global audiences.

Cortisol, often dubbed the “stress hormone,” is produced by the adrenal glands and plays a critical role in helping the body respond to stress. When stress levels rise, so does the production of cortisol, which can affect multiple body systems—regulating metabolism, controlling blood sugar, influencing immune responses, and aiding in fat storage. According to a recent report by the National Post, online searches for information on cortisol, its “trigger foods,” and supposed “cortisol detoxes” have climbed dramatically in the past year, reflecting the growing anxiety about how stress hormones may visibly influence appearance and health (MSN).

A new wave of scientific concern is sweeping the globe after researchers found a strong association between consuming ultra-processed foods and a shortened lifespan, according to a recent study highlighted in Prevention magazine. The findings, reported earlier this year, reinforce mounting evidence that diets high in heavily processed foods—such as instant noodles, packaged snacks, sweetened beverages, and ready-to-eat meals—could be taking tangible years off people’s lives, raising urgent public health questions for Thailand and beyond.

A social media fitness influencer with over five million followers has ignited a widespread controversy after publicly sharing that her recent weight loss success involved the use of a GLP-1 class medication, commonly known by names such as Ozempic and Mounjaro. The disclosure, made in a YouTube video titled “Let’s talk: Therapy, GLP-1 & The Truth About My Recent Weight Loss,” has set off heated discussions about transparency, ethical responsibility, and the realities of the online wellness industry.

Chile’s bold efforts to curb childhood junk food consumption have sparked international attention, prompting the question: if Chile can do it, why can’t the UK—or, indeed, Thailand? The South American nation’s sweeping package of regulations, focusing on marketing and labeling, has spurred a dramatic decline in unhealthy snack intake by children. This development has brought fresh hope to public health officials worldwide grappling with rising obesity rates among the youth.

Scrolling through TikTok or social media, many Thai readers may have encountered alarming claims asserting that stress-induced cortisol is the main culprit behind stubborn belly fat and unwanted facial changes, often labelled “cortisol belly” and “cortisol face”. However, a recent analysis published by The Conversation dispels much of this online panic, highlighting that the scientific evidence paints a far more nuanced picture and suggesting Thais need not obsess over this hormonal hype.

Human understanding of how the brain creates, stores, and retrieves memories may be on the verge of a radical transformation, as cutting-edge research from a team at Trinity College Dublin has upended decades-old theories about memory. Led by a leading neuroscientist at the college’s Institute of Neuroscience, this fresh research shows that memories are not locked away in single neurons as previously thought, but rather stored via complex interactions between groups of special neurons known as “engram cells.” The implications for neurological disorders, learning, and even the way we regulate our bodies are profound.

A wave of new research is shedding light on the intriguing ways that your birth order—whether you’re a firstborn, middle child, youngest, or only child—can impact not just your personality, but also your risks for certain mental and physical health conditions. The longstanding folk wisdom about eldest siblings being responsible, middle children overlooked, and youngest siblings more carefree has some scientific roots—but the picture is far more complex, with direct relevance for families in Thailand and around the world.

A wave of excitement has hit health and wellness circles following claims that a “fasting mimicking diet” (FMD) can help individuals lose stubborn belly fat in as little as five days. Recent headlines, like the one from First for Women, are stirring curiosity and hope among those looking for quick, effective, and sustainable weight loss solutions. But can this new dietary protocol truly deliver such dramatic results, or is it merely the latest fad to sweep social media?

As diet sodas, low-calorie snacks, and “sugar-free” treats line supermarket shelves across Thailand, consumers are turning in increasing numbers to artificial sweeteners in hopes of enjoying sweet flavors without the adverse health effects of sugar. However, a growing wave of scientific research is challenging the widespread belief that artificial sweeteners are a healthier choice, suggesting instead that these calorie-free sugar substitutes may bring their own health risks — including increased appetite, fat accumulation, and potentially heightened risk of obesity and type 2 diabetes, according to a recent exposé published by The Independent and corroborated by the latest global studies (The Independent).
