https://medicalxpress.com/overweight-obesity-news/ en-us Latest health news and information about Weight Management 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 A new study has identified why many men struggle with weight loss, finding that traditional diet programs are often perceived as too restrictive and primarily aimed at women. The research, published in PLOS One and led by Anglia Ruskin University (ARU) in England, is the first academic study to investigate men's motivation for losing weight, their personal experiences and the weight-loss approaches they find most appealing. https://medicalxpress.com/news/2026-08-men-struggle-weight-loss.html Wed, 26 Aug 2026 14:00:28 EDT news706959181 Obesity doesn't look the same at age 15 as it does at age 45, and Duke University School of Medicine researchers are learning why. A study published in the Journal of Clinical Investigation showed teenagers retain a degree of metabolic flexibility that's largely lost in adulthood. The study suggests that the way teenage bodies respond to excess weight is fundamentally different and potentially more reversible. https://medicalxpress.com/news/2026-08-obesity-adolescence-reversible-previously-thought.html Mon, 24 Aug 2026 13:20:09 EDT news706792201 Glucagon-like peptide 1 receptor agonists (GLP-1RA), commonly used to treat diabetes and weight loss, may have additional mental health benefits, especially for people with bipolar disorder, new Griffith University research has found. https://medicalxpress.com/news/2026-08-weight-loss-drugs-avenue-bipolar.html Mon, 24 Aug 2026 08:40:05 EDT news706773301 Research published in Diabetologia by Amsterdam UMC and the University of Ghana reveals that type 2 diabetes manifests in two fundamentally different ways depending on a patient's body mass index (BMI). While type 2 diabetes in patients with a higher BMI is primarily driven by insulin resistance, the study demonstrates that in individuals within a lower BMI range, the condition is caused by the pancreas failing to produce sufficient insulin. Despite these opposing biological mechanisms, medical professionals currently treat both groups with the same medications. https://medicalxpress.com/news/2026-08-size-doesnt-diabetes-differently-weight.html Mon, 24 Aug 2026 00:00:01 EDT news706526221 Imagine the body's immune cells as a neighborhood cleanup crew. When all is healthy, macrophages roam tissues, clearing away cellular debris and helping maintain order. But obesity can turn these normally protective cells into drivers of chronic inflammation and metabolic disease. https://medicalxpress.com/news/2026-08-macrophage-molecular-scissors-obesity-linked.html Sun, 23 Aug 2026 10:20:01 EDT news706201640 Over the past five years, medications called GLP-1s have revolutionized the treatment of metabolic disorders like obesity, diabetes and fatty liver disease. Sold under the brand names Ozempic, Wegovy, Mounjaro and Zepbound, these drugs are highly effective at helping people lose weight and manage their blood sugar levels. However, they do come with some risks. https://medicalxpress.com/news/2026-08-weight-loss-diabetes-treatment-fat.html Fri, 21 Aug 2026 14:00:09 EDT news706527422 Participants who followed a Mediterranean-style plan tailored for the Southeast not only kept weight off but also ate better in ways that may help prevent chronic disease. https://medicalxpress.com/news/2026-08-mediterranean-style-tailored-southeast-weight.html Thu, 20 Aug 2026 13:40:07 EDT news706446421 People using weight-loss drugs are more likely to seek advice from social media than health care professionals, a Coventry University–led study has found. Researchers from the U.K. and Canada found that users of GLP-1 medications—weight-loss drugs such as Ozempic, Wegovy and Mounjaro that help regulate appetite and blood sugar levels—often rely on social media, online forums, friends and family for information about the drugs. Almost half (48%) of participants said social media was a source of information, while health care professionals were consulted less frequently. https://medicalxpress.com/news/2026-08-weight-loss-drug-users-social.html Wed, 19 Aug 2026 09:00:07 EDT news706345741 When it comes to daily aches and pains, it's not uncommon for knees to be a main source. And while there can be many different long-term causes of such issues, osteoarthritis is often a reason why. https://medicalxpress.com/news/2026-08-osteoarthritis.html Tue, 18 Aug 2026 23:00:02 EDT news706258113 While consumers may save a few bucks on groceries at dollar stores, they end up paying a higher price with their health. New UC Riverside research shows a link between dollar store food quality and higher rates of obesity, high blood pressure, cholesterol and type 2 diabetes. https://medicalxpress.com/news/2026-08-hidden-health-dollar-groceries.html Tue, 18 Aug 2026 19:00:04 EDT news706292881 Obesity can weaken the immune system's tumor-killing responses in lung cancer, leading to disease progression, but a new study by experts at Roswell Park Comprehensive Cancer Center reveals that exercise may reverse this effect. https://medicalxpress.com/news/2026-08-obesity-weakens-anti-tumor-immune.html Mon, 17 Aug 2026 12:40:07 EDT news706185962 Traditionally, obesity has been classified primarily using BMI, a measure of weight relative to height that provides limited information about whether excess fat is actually affecting a person's health. BMI levels have historically played a central role in determining eligibility and priority for metabolic bariatric surgery—operations on the stomach that help people lose weight and treat health conditions, such as type 2 diabetes. https://medicalxpress.com/news/2026-08-obesity-definitions-reveal-ill-health.html Sat, 15 Aug 2026 13:20:01 EDT news705918615 Measuring waist size may be one of the simplest and most effective ways to detect obesity-related health risks, according to a study by Rutgers Health researchers. https://medicalxpress.com/news/2026-08-waist-size-powerful-indicator-health.html Fri, 14 Aug 2026 15:20:02 EDT news705933541 GLP-1 receptor agonists and dual agonists have transformed the treatment of obesity and other metabolic diseases, and a new editorial co-authored by Dr. Steven Heymsfield of LSU's Pennington Biomedical Research Center and Dr. Adam Gilden of the University of Colorado examines what scientists are learning as these medications reach millions of people. https://medicalxpress.com/news/2026-08-unanticipated-benefits-glp-medications.html Fri, 14 Aug 2026 14:20:01 EDT news705935134 Three minutes of sprinting can do something that 90 minutes of moderate exercise apparently cannot: dramatically reshape the molecular contents of the bloodstream. Rockefeller researchers comparing different intensities of exercise found that six sets of 30-second, all-out sprints altered nearly a quarter of the proteins measured immediately afterward. Moderate, continuous cycling for 90 minutes altered fewer than one-quarter of 1%. And while moderate treadmill running changed more proteins than cycling, it still altered far fewer than a quick sprint. https://medicalxpress.com/news/2026-08-minutes-sprinting-bigger-impact-moderate.html Thu, 13 Aug 2026 11:00:01 EDT news705833761 Coffee is one of the world's most widely consumed beverages, and previous research has linked its consumption to a lower risk of conditions such as type 2 diabetes and cardiovascular disease. However, the biological mechanisms behind these benefits remain unclear. https://medicalxpress.com/news/2026-08-coffee-consumption-linked-leaner-body.html Thu, 13 Aug 2026 10:00:01 EDT news705833641 What if one of the keys to a healthier metabolism is understanding how and when the liver communicates with the rest of the body? https://medicalxpress.com/news/2026-08-liver-boost-fat-breakdown-potential.html Wed, 12 Aug 2026 18:20:02 EDT news705769741
