Results of the study published in the journal Diabetes, Obesity and Metabolism indicate that although each condition is dangerous on its own, they multiply the risk of mortality when present together. https://medicalxpress.com/news/2026-08-combination-abdominal-obesity-vitamin-d.html Tue, 04 Aug 2026 14:40:05 EDT news705071079 A study of nearly 61,000 women in Denmark finds that women who had a body mass index (BMI) trajectory in the overweight or obesity range during childhood were less likely to have children than women with a normal (average) BMI trajectory. This effect on childlessness was already apparent in their mid-20s. The study is published in JAMA Network Open. https://medicalxpress.com/news/2026-08-overweight-obesity-childhood-childlessness-adulthood.html Tue, 04 Aug 2026 11:00:10 EDT news705059609 One of the many ways obesity harms the human body is through damage to skeletal muscle. This progressive muscle decline, also known as sarcopenia, reduces strength, mobility and the ability to live independently. Unfortunately, most therapies for obesity and related conditions like type 2 diabetes focus solely on managing weight and blood glucose rather than addressing the loss of muscle mass and function itself. Understanding what drives muscle deterioration during obesity and finding ways to reverse it are key to addressing this challenge. https://medicalxpress.com/news/2026-08-immune-cells-key-obesity-muscle.html Tue, 04 Aug 2026 10:00:03 EDT news705047014 A traditional Japanese medicine used for obesity may do more than support weight loss. Researchers at the University of Osaka, working with Kobayashi Pharmaceutical Co., Ltd., investigated whether Bofutsushosan could protect aging tissues from fibrosis—the excessive buildup of scar-like tissue that can make organs stiff and less functional. The study was published in the journal Phytomedicine. https://medicalxpress.com/news/2026-08-traditional-japanese-medicine-ease-age.html Mon, 03 Aug 2026 12:40:07 EDT news704973880 If you're a Black, 34-year-old South African woman living with HIV, antiretroviral (ARV) treatment options have likely been limited to tenofovir disoproxil fumarate (TDF), lamivudine (3TC) and the "gold standard," dolutegravir (DTG). Now, another once-daily, three-drug regimen has been found to be as effective as DTG in suppressing HIV viral load. https://medicalxpress.com/news/2026-08-doravirine-dolutegravir-suppress-hiv-viral.html Mon, 03 Aug 2026 12:00:04 EDT news704977021 A new approach to defining obesity could help physicians better determine which patients need more intensive treatment by focusing on the effects of excess adiposity on organs and tissues rather than relying primarily on whether a person meets a set of metabolic risk thresholds. https://medicalxpress.com/news/2026-07-healthy-obesity-framework-daily-limitations.html Fri, 31 Jul 2026 14:20:03 EDT news704723401 Not every disease announces itself with obvious symptoms. Some develop quietly, going unnoticed until they begin to take a serious toll on health. Metabolic syndrome (MetS) is one of them. Rather than a single disease, it is a combination of at least three conditions—including high blood pressure, high blood sugar, excess belly fat, high triglycerides and low HDL (good) cholesterol—that together raise the risk of heart disease, stroke and type 2 diabetes. https://medicalxpress.com/news/2026-07-equal-metabolic-syndrome.html Fri, 31 Jul 2026 12:40:06 EDT news704696757 A previously unknown microprotein hidden within the human mitochondrial genome may help explain certain forms of type 2 diabetes and could point toward a new precision medicine approach to treating it, according to a new USC study. https://medicalxpress.com/news/2026-07-newly-microprotein-linked-diabetes-precision.html Thu, 30 Jul 2026 15:20:06 EDT news704642701 A man's body fat percentage may be a better indicator of his reproductive health than body mass index (BMI), according to a large study of more than 1,000 Danish men. https://medicalxpress.com/news/2026-07-percentage-body-fat-indicator-men.html Wed, 29 Jul 2026 19:10:01 EDT news704473801 New research from the Guelph Family Health Study (GFHS) has found that circadian rhythm-related genes could influence the risk of obesity in children, highlighting an important connection between sleep and eating behavior. https://medicalxpress.com/news/2026-07-circadian-gene-variants-indicator-obesity.html Tue, 28 Jul 2026 18:00:02 EDT news704469902 GLP-1 medications such as Ozempic have transformed the treatment of type 2 diabetes, helping millions of patients better control their blood sugar while reducing cardiovascular risk and, for many, promoting substantial weight loss. https://medicalxpress.com/news/2026-07-glp-drugs-benefits-physical-health.html Tue, 28 Jul 2026 14:20:04 EDT news704463721 Different varieties and doses of GLP-1 medications can have meaningful differences in how they address heart and metabolic health issues, according to new research led by the Perelman School of Medicine at the University of Pennsylvania. Through an analysis of data from 19 randomized controlled trials, the researchers believe their work points to possible precision medicine applications of GLP-1s beyond weight loss. Their work is published in Diabetes, Obesity, and Metabolism. https://medicalxpress.com/news/2026-07-glp-therapies-tailored-patients-individual.html Mon, 27 Jul 2026 16:20:08 EDT news704386441 Ever wonder why some people crave sweets while others can take them or leave them? Preliminary findings from a new study suggest that people who carry certain genetic variants associated with a preference for sweet or fatty tastes not only tend to eat more of these foods but also have a higher risk of obesity and type 2 diabetes as a result. https://medicalxpress.com/news/2026-07-genes-metabolic-health.html Mon, 27 Jul 2026 14:30:01 EDT news704357516 Childhood obesity affects 1 in 5 children in the U.S., yet most families have limited access to specialized weight-management programs for children. Now, a large clinical trial led by researchers at Washington University School of Medicine in St. Louis, the University of Rochester Medical Center, the LSU Pennington Biomedical Research Center and the American Academy of Pediatrics (AAP) has shown that an effective, family-based treatment model can be delivered in primary care settings to treat children and adolescents with obesity. https://medicalxpress.com/news/2026-07-pediatric-offices-family-based-obesity.html Mon, 27 Jul 2026 11:00:08 EDT news704105173 Noncommunicable diseases—heart disease, stroke, diabetes, cancer—are no longer just a rich-country problem. Across Africa, they are becoming the leading cause of death, driven in part by a simple and overlooked culprit: what people drink. https://medicalxpress.com/news/2026-07-tax-sugary-egypt-disease-us18.html Sun, 26 Jul 2026 17:00:04 EDT news703773462 Thanks to advances in AI, popular calorie-tracking apps can now use a photo of a meal to estimate the nutritional content of what you're eating. Although these apps are convenient, a new study found that four photo-based apps underestimated the calorie and fat content of meals by about a third. https://medicalxpress.com/news/2026-07-photo-based-calorie-tracking-apps.html Sat, 25 Jul 2026 16:30:02 EDT news704101953 Researchers have identified a biological marker that rises and falls as body fat changes, offering new insight into how weight gain and weight loss may influence metabolic health. https://medicalxpress.com/news/2026-07-biomarker-discovery-advance-treatments-obesity.html Fri, 24 Jul 2026 11:20:06 EDT news704109781 Cambridge scientists have solved the mystery of why both stimulating and blocking a particular "switch" in the brain can help people lose weight—findings that could help boost the effectiveness of obesity drugs. https://medicalxpress.com/news/2026-07-distinct-brain-circuits-contradictory-behaviors.html Fri, 24 Jul 2026 05:00:06 EDT news704044861 Young women are leading a worrying increase in early-onset type 2 diabetes diagnoses in England, according to a new analysis. In a population study of type 2 diabetes in England, researchers found a clear generational divide, with diagnosis rates rising rapidly among younger adults, particularly women, while declining in older age groups. https://medicalxpress.com/news/2026-07-young-women-england-early-onset.html Wed, 22 Jul 2026 11:20:03 EDT news703937521 Researchers have developed a breath detector with a chemical sensor that sniffs out when your body is burning fat through a single exhale. Reporting in Device, the handheld, smartphone-assisted device measures acetone—a molecule that is released into the breath when the body burns fat—in about 90 seconds with laboratory-level accuracy. https://medicalxpress.com/news/2026-07-breathalyzer-body-fat.html Wed, 22 Jul 2026 11:00:05 EDT news703841521 Hispanic and Asian adults with longer durations of U.S. residence have a higher prevalence of obesity, according to a research letter published in the Annals of Internal Medicine. https://medicalxpress.com/news/2026-07-obesity-immigrants-longer-duration-residence.html Wed, 22 Jul 2026 08:20:05 EDT news703924955 Women with polyendocrine metabolic ovarian syndrome (PMOS; also known as polycystic ovary syndrome or PCOS) face a fourfold higher risk of heart disease than women without PMOS, according to a new nationwide U.S. study published in The Lancet Obstetrics, Gynaecology, & Women's Health. https://medicalxpress.com/news/2026-07-women-pmos-higher-heart-disease.html Tue, 21 Jul 2026 22:20:01 EDT news703857371 Heart failure already affects more than 60 million people worldwide and is one of the leading causes of hospitalization among people 65 and older. Although it is commonly associated with advanced cardiovascular disease, it actually develops over many years, often without symptoms. Authors of a new expert statement published in the European Heart Journal argue that this is precisely why prevention may become the most effective weapon in tackling one of the greatest challenges of modern medicine. https://medicalxpress.com/news/2026-07-latest-evidence-factors-early-intervention.html Tue, 21 Jul 2026 21:20:04 EDT news703856966 Use of newer GLP-1 receptor agonists (semaglutide or tirzepatide) for obesity or diabetes among people with alcohol use disorder was associated with a reduction in alcohol-related hospital admissions, according to a study published online in the open-access journal BMJ Open. https://medicalxpress.com/news/2026-07-obesity-drugs-linked-alcohol-hospitalizations.html Tue, 21 Jul 2026 18:30:01 EDT news703828526 People taking semaglutide for weight loss continued to consume significantly fewer calories after 60 weeks on the medication, helping explain how the medication supports both initial weight loss and long-term weight maintenance. The study, published in the American Journal of Clinical Nutrition and led by investigators from Penn's Center for Weight and Eating Disorders and Penn Metabolic Medicine, is among the first to examine the long-term effects of semaglutide on eating behavior beyond the initial months of treatment. https://medicalxpress.com/news/2026-07-semaglutide-sustains-calorie-intake-year.html Tue, 21 Jul 2026 15:40:02 EDT news703857028 Repeatedly losing and gaining weight may do more than frustrate dieters—it also accelerates muscle loss in middle-aged people, according to new UC San Francisco research that comes as weight-loss medications transform obesity treatment. https://medicalxpress.com/news/2026-07-fat-yo-dieting-muscle.html Tue, 21 Jul 2026 13:00:03 EDT news703855321
