Article Abstract
Background: Online weight loss information is commonly sought by internet users, and it may impact their health decisions and behaviors. Previous studies examined a limited number of Google search queries and relied on manual approaches to retrieve online weight loss websites.
Objective: This study aimed to identify and describe the characteristics of the top weight loss websites on Google.
Methods: This study gathered 432 Google search queries collected from Google autocomplete suggestions, "People Also Ask" featured questions, and Google Trends data. A data-mining software tool was developed to retrieve the search results automatically, setting English and the United States as the default criteria for language and location, respectively. Domain classification and evaluation technologies were used to categorize the websites according to their content and determine their risk of cyberattack. In addition, the top 5 most frequent websites in nonadvertising (ie, nonsponsored) search results were inspected for quality.
Results: The results revealed that the top 5 nonadvertising websites were healthline.com, webmd.com, verywellfit.com, mayoclinic.org, and womenshealthmag.com. All provided accuracy statements and author credentials. The domain categorization taxonomy yielded a total of 101 unique categories. After grouping the websites that appeared less than 5 times, the most frequent categories involved "Health" (104/623, 16.69%), "Personal Pages and Blogs" (91/623, 14.61%), "Nutrition and Diet" (48/623, 7.7%), and "Exercise" (34/623, 5.46%). The risk of being a victim of a cyberattack was low.
Conclusions: The findings suggested that while quality information is accessible, users may still encounter less reliable content among various online resources. Therefore, better tools and methods are needed to guide users toward trustworthy weight loss information.

[Focus on bariatric endoscopy in Belgium].
Rev Med Liege

Service de Gastroentérologie, CHU Liège, Belgique.
Bariatric endoscopy is an increasingly recognized alternative to surgery for obesity treatment. Recent guidelines from leading medical societies (IFSO, ASMBS, ASGE, ESGE) have included endoscopic sleeve gastroplasty (ESG) and the intragastric balloon (IGB) in their recommendations. These procedures are indicated for patients with a body mass index (BMI) between 27 and 40 kg/m² who cannot or do not wish to undergo surgery.

Integrative Muscle Biology Laboratory, Division of Rehabilitation Sciences, College of Health Professions, University of Tennessee Health Science Center, Memphis, Tennessee, USA.
Background: Cancer promotes muscle wasting through an imbalance in the tightly regulated protein synthesis and degradation processes. An array of intracellular signalling pathways, including mTORC1 and AMPK, regulate protein synthesis, and these pathways are responsive to the muscle's microenvironment and systemic stimuli. Although feeding and fasting are established systemic regulators of muscle mTORC1 and protein synthesis, the cancer environment's impact on these responses during cachexia development is poorly understood.

Obesity (Silver Spring)
September 2025
Department of Nutrition Sciences, University of Alabama at Birmingham (UAB), Birmingham, Alabama, USA.
Objective: This secondary analysis was conducted to compare the magnitude of adaptive thermogenesis (AT) following hypocaloric low-carbohydrate (CHO) versus low-fat diets in African American (AA) women.
Methods: Sixty-nine AA women with obesity were randomized to low-CHO or low-fat hypocaloric diets for 10 weeks, followed by a 4-week weight stabilization period (all food provided). At baseline and Week 13, insulin sensitivity (S) was measured by intravenous glucose tolerance test, body composition by bioimpedance analysis, total energy expenditure (EE) (TEE) by doubly labeled water, and resting EE (REE) by indirect calorimetry.
Exploratory Assessment of Preoperative GLP-1 Receptor Agonists Before Sleeve Gastrectomy: A Retrospective Matched Analysis.
Obes Surg
September 2025
Clinique Mutualiste de Pessac, Pessac, France.
Background: Preoperative treatment with glucagon-like peptide-1 receptor agonists (GLP-1 RAs) before bariatric surgery has not been studied. Therefore, we investigated the impact of neoadjuvant treatment with GLP-1 RAs on weight loss and postoperative outcomes in patients who underwent sleeve gastrectomy for severe obesity.
Method: A retrospective single-center study was conducted between January 2022 and December 2023.

E-Da Hospital, Kaohsiung City, Taiwan.
Background: We retrospectively evaluated the efficacy of using additional obesity management medications (OMMs) within the first year after undergoing laparoscopic sleeve gastrectomy (LSG).
Methods: We retrospectively analyzed 246 patients who underwent primary LSG in our institution and were followed up for at least 12 months. We collected body weights preoperatively and at three, six, 12, and 24 months postoperatively, along with body composition and laboratory results preoperatively and at 12 months.
