A new study conducted at the Gray Faculty of Medical and Health Sciences and the Sylvan Adams Sports Science Institute at Tel Aviv University reveals a clear conclusion: strength (resistance) training is the most effective tool for achieving "high-quality" weight loss, reducing body fat while preserving, and even increasing, muscle mass. https://medicalxpress.com/news/2026-02-strength-healthiest-dieting-results-sexes.html Mon, 09 Feb 2026 19:20:01 EST news689868033 Just over one in 10 deaths from a wide range of infectious diseases can be attributed to obesity worldwide, finds a major new study led by a University College London (UCL) researcher. People with obesity face a 70% higher risk of hospitalization or death from an infection than those of a healthy weight, according to the findings published in The Lancet. https://medicalxpress.com/news/2026-02-obesity-linked-infection-deaths-globally.html Mon, 09 Feb 2026 18:30:03 EST news689848501 Obesity and older age are strongly associated with low-grade inflammation in the body, a condition that appears closely linked to cognitive decline and dementia. A recent Baycrest study has found that participants with elevated inflammation levels make up roughly two-thirds of those with cognitive impairment, compared with only about one-third of cognitively healthy adults. https://medicalxpress.com/news/2026-02-obesity-aging-links-inflammation-cognitive.html Mon, 09 Feb 2026 17:06:44 EST news689879161 The Winter Olympics and Paralympics are upon us once again. This year the games come to Milan and Cortina d'Ampezzo, Italy, where weather forecasts are predicting temperatures in the upper 30s to mid-40s Fahrenheit (1 to 10 degrees Celsius). https://medicalxpress.com/news/2026-02-winter-olympians-temperatures-physiology-advances.html Mon, 09 Feb 2026 11:55:43 EST news689860502 Time-restricted eating has emerged as a popular dietary approach because it focuses on when people eat rather than strictly limiting calories. Instead of counting calories, individuals restrict their daily food intake to a defined time window. While this approach has been widely studied, most research has focused on whether time-restricted eating works, with less attention paid to how eating timing and eating duration interact. https://medicalxpress.com/news/2026-02-meal-restricted-metabolic-health.html Sun, 08 Feb 2026 14:00:02 EST news689608256 Pregnancy is, biologically speaking, a state of controlled upheaval. The immune system recalibrates. Blood volume surges. And sometimes, inflammation rises to unsafe levels, with potential adverse health effects for both parent and child. A new study suggests that choline, a nutrient many pregnant people consume too little of, may play an underappreciated role in keeping inflammation in check. The findings are published in The Journal of Nutrition. https://medicalxpress.com/news/2026-02-choline-pregnancy-inflammation.html Thu, 05 Feb 2026 12:40:29 EST news689517601 Parkinson's disease, a progressive neurological disorder affecting more than 1 million people in the U.S. and more than 10 million globally, is characterized by debilitating symptoms such as tremors, movement difficulties, sleep disturbances and cognitive impairments. While current treatments, including long-term medication and invasive deep brain stimulation (DBS), can alleviate symptoms, they cannot halt progression or cure the disease. https://medicalxpress.com/news/2026-02-brain-network-responsible-parkinson-disease.html Wed, 04 Feb 2026 11:00:03 EST news689415121 Transgender women might have more muscle mass than cisgender women one to three years after hormone therapy, but their physical fitness is comparable, finds a pooled data analysis of the available evidence, published online in the British Journal of Sports Medicine. https://medicalxpress.com/news/2026-02-physical-transgender-cisgender-women-current.html Tue, 03 Feb 2026 18:30:03 EST news689319241 Canadian parents face multiple barriers to providing their children with reliable and culturally appropriate sex education, according to research published in Sexual & Reproductive Healthcare from the University of Alberta. "My motivation is to deeply understand parents' experiences and what holds them back, and build a system to empower families rather than just leave them to navigate all these conversations by themselves," says principal investigator Neelam Punjani, who undertook the research as part of her postdoctoral fellowship and is now an assistant professor in the U of A's Faculty of Nursing. https://medicalxpress.com/news/2026-02-children-sexuality.html Mon, 02 Feb 2026 11:11:43 EST news689253062 Protein is having a moment, with federal guidelines significantly raising the recommended amount people should eat every day and products ranging from coffee drinks to Pop-Tarts touting enhanced levels of the nutrient. Eating enough protein is important for good health, Denver-area dieticians said, but people who want to increase their intake need to make sure they choose quality foods and don't crowd out healthy carbohydrates and fats. https://medicalxpress.com/news/2026-01-protein-rage.html Sat, 31 Jan 2026 05:40:02 EST news688973610 Elevated body mass index (BMI) and physical inactivity are metabolic drivers of hypertension-related chronic kidney disease (HT-CKD), with elevated BMI exerting a greater impact, according to a study published online Jan. 11 in Frontiers in Nutrition. https://medicalxpress.com/news/2026-01-elevated-bmi-physical-inactivity-metabolic.html Fri, 30 Jan 2026 19:30:01 EST news689002002 A research team at the Korea University College of Medicine has uncovered a genetic mechanism responsible for delayed tooth development and impaired mineralization. The team, led by Professor Hae-chul Park (Department of Biomedical Sciences, Korea University College of Medicine) and Professor Ji-suk Shim (Department of Dentistry, Korea University College of Medicine), investigated the role of the Axin2 gene, which encodes a negative regulator of the Wnt/β-catenin signaling pathway—a critical pathway that orchestrates cell proliferation, differentiation, and organogenesis. https://medicalxpress.com/news/2026-01-gene-delayed-softer-teeth-zebrafish.html Thu, 29 Jan 2026 12:40:05 EST news688912582 About one in three older adults fall each year, which often leads to broken bones, hip fractures, and other injuries that can contribute to a marked decline in their quality of life and leads to over $50 billion in medical costs annually. Hip fractures are often life-altering events that precede long-term loss of mobility, independence, and overall well-being for older adults. Notably, falls that happen while the individual is turning are almost eight times more likely to cause a hip fracture than falls that occur while walking straight. https://medicalxpress.com/news/2026-01-older-adults-movements-reveal-hidden.html Wed, 28 Jan 2026 16:00:05 EST news688838163 A multicenter research effort in China conducted clinical trial testing of oral berberine for six months in diabetes-free adults with obesity and metabolic dysfunction-associated steatotic liver disease. Visceral adipose tissue area and liver fat content showed no significant differences between berberine and placebo. https://medicalxpress.com/news/2026-01-berberine-advantage-placebo-liver-belly.html Wed, 28 Jan 2026 09:41:47 EST news688815598 Older people are better at reading facial expressions than younger people in real-life situations, according to new research from the University of Aberdeen. The study, published in Aging, Neuropsychology, and Cognition, found that older adults were better at deciphering facial expressions than their younger counterparts but only in a "real-life" context. The effect was reversed when all context was removed. https://medicalxpress.com/news/2026-01-granny-reveals-older-adults-emotions.html Wed, 28 Jan 2026 09:19:49 EST news688814341 Researchers at the University of Oulu have identified genes that increase susceptibility to pneumonia. Alongside inherited risk factors, smoking and higher body mass were also found to raise the risk of developing the disease. The study, published in eBioMedicine, identified a total of 12 genetic regions associated with pneumonia risk, eight of which were identified for the first time. Many of these regions are linked to the regulation of the body's inflammatory response. However, among patients with recurrent pneumonia and among older patients, genes associated with nicotine dependence played a particularly prominent role. https://medicalxpress.com/news/2026-01-genes-obesity-pneumonia-older-adults.html Tue, 27 Jan 2026 14:58:27 EST news688748281 People who don't eat meat may be less likely than meat eaters to reach the age of 100, according to a recent study. But before you reconsider your plant-based diet, there's more to these findings than meets the eye. https://medicalxpress.com/news/2026-01-meat-eaters.html Mon, 26 Jan 2026 12:32:51 EST news688653122 Women with cervical cancer who experience significant muscle loss during treatment die at six times the rate of those who maintain muscle mass, according to an international review of 23 studies involving more than 4,000 patients. https://medicalxpress.com/news/2026-01-muscle-loss-cervical-cancer-treatment.html Sat, 24 Jan 2026 10:00:04 EST news688229939 Scientists may have found a new way to spot early signs of obesity, which could lead to novel prevention strategies. A study published in the journal Cell Reports has discovered that people living with obesity have a distinct set of microbes in their mouths compared to people at a healthy weight. https://medicalxpress.com/news/2026-01-microbes-mouths-key-obesity.html Fri, 23 Jan 2026 09:43:02 EST news688383399 A short-term oat-based diet appears to be surprisingly effective at reducing the cholesterol level. This is indicated by a trial by the University of Bonn, which has now been published in Nature Communications. The participants suffered from a metabolic syndrome—a combination of high body weight, high blood pressure, and elevated blood glucose and blood lipid levels. They consumed a calorie-reduced diet, consisting almost exclusively of oatmeal, for two days. Their cholesterol levels then improved significantly compared to a control group. Even after six weeks, this effect remained stable. The diet apparently influenced the composition of microorganisms in the gut. https://medicalxpress.com/news/2026-01-days-oatmeal-cholesterol.html Fri, 23 Jan 2026 09:24:46 EST news688382643 Long-distance cyclists can preserve fat-free body mass while on a plant-based diet, according to new research involving a University of Alberta nutrition expert. https://medicalxpress.com/news/2026-01-based-diets-fuel-ultra-athletes.html Thu, 22 Jan 2026 10:50:26 EST news688301401 Teenage girls who maintain a "normal" body weight through constant dieting and exercise may look "healthy" but should be seen as a vulnerable group, according to new research from the University of Warwick.
