https://medicalxpress.com/overweight-obesity-news/ en-us Latest health news and information about Weight Management 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 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 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 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 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 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 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 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 Adolescents and young adults in the U.S. are increasingly using popular GLP-1 weight-loss drugs alone or in conjunction with metabolic and bariatric surgery (MBS) to manage obesity, according to a study by UT Southwestern Medical Center researchers published in JAMA Pediatrics. https://medicalxpress.com/news/2026-07-glp-rapidly-adolescents-young-adults.html Mon, 20 Jul 2026 15:40:06 EDT news703778101 Body Mass Index (BMI) has long been used in public health and clinical settings as a simple tool to classify an individual's physical status based on their height and weight. Originally developed in the 1830s by Belgian mathematician Adolphe Quetelet, BMI was designed to describe the characteristics of the average man rather than to assess an individual's health, and it did not account for age, sex, ethnicity or body composition. https://medicalxpress.com/news/2026-07-body-index-aims-bmi-babies.html Fri, 17 Jul 2026 07:50:02 EDT news703491612
