Now, scientists from Harrington Discovery Institute at University Hospitals and Case Western Reserve University have identified why. https://medicalxpress.com/news/2026-09-fat-cells-retain-hunger-weight.html Fri, 11 Sep 2026 14:40:04 EDT news708352441 Obesity caused by disrupted stress-hormone rhythms is metabolically very different from obesity caused by a high-fat diet, according to a new preclinical study by Weill Cornell Medicine investigators. The researchers found in mice that glucocorticoid-rhythm disruption concentrates insulin resistance in skeletal muscle while preserving key insulin responses in fat tissue and liver. This allows fat tissue to continue storing lipids, while the liver remains largely protected from the fat accumulation typically seen with high-fat-diet obesity. https://medicalxpress.com/news/2026-09-stress-hormone-kind-obesity.html Thu, 10 Sep 2026 16:20:04 EDT news708269881 One in eight people worldwide does not get an uninterrupted night's sleep because of obstructive sleep apnea (OSA). This sleep disorder causes people to wake up suddenly when a blockage or narrowing in the upper airway prevents air from flowing properly through the windpipe. These repeated interruptions can leave a person exhausted, even after what's technically a full night's sleep. Obesity is a contributing factor to this sleep disorder, so researchers reviewed existing literature to see how GLP-1 receptor agonist medications, a class of weight-loss and diabetes drugs, can be used to treat OSA. https://medicalxpress.com/news/2026-09-popular-weight-loss-drug-doctors.html Thu, 10 Sep 2026 08:29:26 EDT news708247720 An experimental cancer drug could stop osteoporosis and help women stay slim after menopause, according to new research from the University of East Anglia. The study, published in npj Drug Discovery, reveals that a compound originally designed to fight cancer may not only protect against osteoporosis—but could also reduce body fat and reverse some of the metabolic changes linked to menopause. https://medicalxpress.com/news/2026-09-experimental-cancer-drug-millions-women.html Mon, 07 Sep 2026 05:00:04 EDT news707737319 Researchers at UT Southwestern Medical Center have identified a key brain signaling pathway that appears to drive the substantial weight gain often associated with clozapine, a widely used antipsychotic medication. The preclinical findings, published in Nature Communications, point to a potential way to reduce the metabolic side effects of this medication, commonly prescribed for patients with treatment-resistant schizophrenia. https://medicalxpress.com/news/2026-09-brain-mechanism-clozapine-weight-gain.html Sun, 06 Sep 2026 17:00:08 EDT news707666179 Although the number of U.S. children under age 12 with obesity who are prescribed the weight-loss drugs Saxenda, Wegovy and Zepbound remains low, it was 310 times higher in June 2026 than in 2019, when the drugs were first prescribed, a new study shows. https://medicalxpress.com/news/2026-09-glp-young-children-obesity-rare.html Fri, 04 Sep 2026 00:00:01 EDT news707573886 Men already genetically at risk for the most common form of hair loss have a 7% added risk of losing their hair if they use drugs like Ozempic, Wegovy and Zepbound for type 2 diabetes and obesity, a new study shows. https://medicalxpress.com/news/2026-09-hair-loss-men-linked-weight.html Thu, 03 Sep 2026 00:00:01 EDT news707486965 High-fructose corn syrup is just one of many food additives linked to obesity. It is typically found in sweetened beverages and processed foods and is added to enhance flavor and sweetness. However, exactly how it contributes to weight gain and obesity is not completely understood. https://medicalxpress.com/news/2026-09-scientists-fructose-obesity.html Wed, 02 Sep 2026 13:50:02 EDT news707572905 If you're depending on your smartwatch to tell you the truth about how many calories you burned during a workout—well, don't. https://medicalxpress.com/news/2026-09-smartwatch-calories.html Tue, 01 Sep 2026 17:40:07 EDT news707501404 There is no link between the widely used diabetes and obesity medications known as GLP-1 receptor agonists and increased suicidal thoughts, depression or other serious psychiatric harm, based on an integrative review of current scientific evidence conducted by researchers at New Mexico State University and the University of Nevada, Las Vegas. https://medicalxpress.com/news/2026-08-glp-1s-major-psychiatric.html Mon, 31 Aug 2026 19:00:01 EDT news707398682 According to the World Health Organization, one in eight people lives with obesity. Yet despite numerous health education programs, books, articles and treatments, many individuals still struggle to lose weight once they have developed obesity. Why this is so difficult remains a complex puzzle for scientists. https://medicalxpress.com/news/2026-08-immune-cells-biological-memory-weight.html Mon, 31 Aug 2026 13:00:03 EDT news707399579 A diet that severely limits carbohydrates but is high in fat has the greatest health benefits for people with obesity compared with a Mediterranean diet or a low-fat diet, according to a clinical trial published Aug. 27 in the journal Cell Metabolism. After following a ketogenic (or "Keto") diet for four to five months, about 50% of a group of participants with obesity and prediabetes no longer met the criteria for prediabetes. https://medicalxpress.com/news/2026-08-keto-diet-greater-health-benefits.html Thu, 27 Aug 2026 11:00:03 EDT news707045101
