Bariatric Endoscopic Antral Myotomy Combined With Fundal Gastric Mucosal Ablation

The gastric fundus regulates appetite through orexigenic ghrelin-mediated and anorexigenic visceroceptive pathways. Accordingly, endoscopic gastric fundal mucosal ablation (GFMA) may benefit patients with obesity. Ablation not only affects these mechanisms, but similar to what happens after mucosal ablation for other indications (e.g. ESD for tumor removal), it is expected to cause shrinking of the fundus and reduce gastric volume. Another potential target to achieve weight loss is gastric emptying. This is a critical step in digestion that has been found to be more rapid after prolonged exposure to a high-fat diet in both animal and human studies, with rapid emptying also being more common in young people with obesity in some studies. The bariatric endoscopic antral myotomy (BEAM) procedure has been shown to consistently delay gastric emptying without triggering symptoms of gastroparesis and to produce substantial weight loss. Both GFMA and BEAM procedures have the advantages of being minimally invasive, performed completely endoscopic and less costly than surgical alternatives or other known endoscopic techniques like intragastric balloon or endoscopic sleeve gastroplasty.

Exercise Training and Vitamin D Metabolism

The prevalence of Vitamin D deficiency is significantly higher in adults with overweight/obesity compared to those with normal body mass index (BMI). The "entrapment" of Vitamin D in adipose tissue due to impaired lipolytic stimulation and/or adipose tissue dysfunction has been proposed as the driving mechanism. Exercise training has been proposed as a promising strategy to increase mobilization of Vitamin D from adipose tissue, given its well described role in stimulating lipolysis. Indeed, a recent study revealed that participation in moderate-intensity cardiovascular type exercise over winter can mitigate the decline in 25-hydroxyvitamin D \[25(OH)D\] in adults with overweight/obesity, independent of weight loss. The aim of this study is to investigate the impact of hybrid-type high-intensity interval training over winter on vitamin D metabolism, in adults with overweight/obesity.

Reliability and Validity of Physical Performance Tests in Individuals With Obesity

This study aims to investigate the reliability and validity of practical performance-based physical function tests in individuals with obesity. Functional limitations such as reduced walking ability, impaired balance, and decreased lower extremity strength are common in people with obesity and may negatively affect daily activities and quality of life. Participants will complete several commonly used clinical functional tests, including the 1-Minute Stair Climbing Test, 40-Meter Fast-Paced Walk Test, 2-Minute Walk Test, Timed Up and Go Test, and 30-Second Sit-to-Stand Test. In addition, cardiopulmonary exercise testing, balance assessment, and knee extensor muscle strength measurements will be performed. The study will evaluate whether these simple and clinically applicable tests provide reliable results over repeated measurements and whether they are associated with objective indicators of physical function such as maximal oxygen consumption (VO₂max), balance performance, and muscle strength. The findings may help clinicians use practical and cost-effective tools to assess physical function in individuals with obesity.

A Study of NatureU Burn on Satiety in Healthy Adults

This single-center, single-blind, non-randomized crossover exploratory study evaluated the short-term effects of NatureU Burn on postprandial satiety in healthy adults. NatureU Burn is an oral dietary supplement containing Irvingia gabonensis seed extract and high-molecular-weight inulin. Fourteen healthy adults were enrolled, and 12 participants completed the study and were included in the effectiveness analysis. Each participant completed two test sessions separated by at least 48 hours: a reference food session with 75 g medical anhydrous glucose in 250 mL warm purified water and a test food session with one capsule of NatureU Burn plus 75 g glucose in 250 mL warm purified water. Satiety-related questionnaire scores were assessed at fasting baseline and at 30, 60, 90, 120, 180, and 240 minutes after the first bite in each session. The study assessed fullness, hunger, desire for food, and prospective food consumption, and monitored adverse reactions.

Retrospective Evaluation of Sibutramine-Topiramate Therapy for Obesity in Real-World Outpatient Practice

This retrospective real-world cohort study aims to evaluate the effectiveness, safety, and tolerability of the combination of sibutramine and topiramate in the treatment of obesity and overweight associated with metabolic comorbidities in adult patients treated in an outpatient clinical setting. Obesity is a chronic, multifactorial, and progressive disease associated with substantial metabolic, cardiovascular, and psychosocial burden. Although newer anti-obesity therapies such as GLP-1 receptor agonists and dual agonists have demonstrated high efficacy, their elevated cost significantly limits accessibility in low- and middle-income populations and restricts widespread implementation in routine clinical practice. Consequently, there is an increasing need for affordable, accessible, and clinically effective pharmacological strategies for obesity management. Sibutramine is a serotonin and norepinephrine reuptake inhibitor that promotes appetite suppression and increased satiety, while topiramate is a neuromodulatory agent with anorexigenic effects mediated through GABAergic and glutamatergic pathways. The pharmacological combination of these agents has been increasingly used in clinical practice because of their complementary mechanisms of action and relatively low cost. Previous studies and observational data have suggested meaningful weight reduction and acceptable tolerability with this combination under appropriate medical supervision. The present study is designed as a retrospective observational cohort based on the review of medical records from adult patients treated between January 2023 and December 2025 at a private outpatient clinic in Brazil. Eligible participants include adults aged 18 years or older with obesity (body mass index \[BMI\] ≥30 kg/m²) or overweight (BMI ≥27 kg/m²) associated with at least one metabolic comorbidity, including type 2 diabetes mellitus, prediabetes, dyslipidemia, or hypertension. Patients must have received concomitant treatment with sibutramine and topiramate for a minimum period of three months and have documented clinical follow-up with at least two consultations containing anthropometric and clinical information. Patients with pregnancy, breastfeeding, uncontrolled hypertension, significant cardiovascular disease, severe psychiatric disorders, epilepsy, nephrolithiasis, glaucoma, severe renal or hepatic disease, or concomitant use of medications known to significantly interfere with body weight will be excluded. Records lacking sufficient anthropometric or clinical follow-up information will also be excluded from analysis. Data extracted from medical records will include demographic variables, baseline body weight, BMI, treatment duration, medication doses, percentage weight change over time, adherence to follow-up, eating behavior control, and adverse events reported during treatment. All information will be anonymized before analysis. No identifiable personal information, including names, telephone numbers, addresses, or identification numbers, will be collected. Data will be stored in password-protected electronic databases accessible only to the principal investigator. The primary outcome is the percentage change in body weight and BMI during treatment with the sibutramine-topiramate combination. Secondary outcomes include the proportion of patients achieving clinically significant weight loss thresholds (≥5%, ≥10%, and ≥15%), early treatment response defined as ≥3% body weight reduction within the first month, treatment adherence, tolerability profile, frequency of adverse events, and subgroup analyses according to age, sex, baseline BMI, and medication dose. Statistical analyses will include descriptive statistics, paired parametric or nonparametric comparisons, and exploratory regression analyses to identify predictors of therapeutic response. Statistical significance will be established at p\<0.05. Because this is a retrospective observational study using exclusively secondary data from medical records, the protocol is classified as minimal risk. There will be no direct patient contact, no intervention, and no modification of standard medical care. The study was approved by the Research Ethics Committee of the Hospital Universitário Cassiano Antônio de Moraes / Federal University of Espírito Santo (HUCAM/UFES), Brazil, under approval number 8.403.776 and CAAE 94334125.7.0000.5071.

The OAT Trail: The Obesity Anti-Coagulation Thromboprophylaxis Trial.

Blood clots in the legs or lungs (called venous thromboembolism or VTE) are one of the most serious complications after weight loss surgery. Most blood clots occur after patients go home from hospital, within the first 30 days after surgery. To prevent blood clots, all patients having weight loss surgery receive a daily blood-thinning injection for 21 days after their operation. Two blood-thinning injections are currently used at St Vincent's University Hospital for this purpose: enoxaparin (Clexane®) and tinzaparin (Innohep®). Both belong to a group of medicines called low molecular weight heparins (LMWHs). Patients with obesity process these medicines differently to the general population, and previous studies from our hospital have shown that fewer than 53% of patients achieve adequate blood-thinning levels with either injection when measured by a blood test called an anti-Xa level. Patients will be randomly assigned (like a coin toss) to receive either tinzaparin or enoxaparin for 21 days after their surgery. Both injections are already in routine use at this hospital. A single extra blood sample will be taken on the second day after surgery to measure the anti-Xa level, which tells us whether the injection is providing adequate protection against blood clots. This blood sample will be taken at the same time as routine post-operative blood tests so that no additional blood draws are required. The study will also look at rates of blood clots and bleeding events within 30 days of surgery, and will ask patients to complete a short questionnaire at their six-week follow-up appointment about their experience with the injection.

Direct Measurement of Microstructure of Ingestive Behaviour After Initiation of GLP-1 Receptor Agonist Treatment at Maximum Dose (DIGRAT)

Ingestion of food instigates the release of a battery of enteroendocrine peptide hormones that help control gut motility and digestive secretion. Peptide hormone products of the enteroendocrine L-cell and GLP-1 in particular, play multiple roles in relation to the regulation of pancreatic islet function and gastric emptying and the induction of satiety pathways in the central nervous system The mechanism of action of GLP-1 RAs on food intake reduction is mainly mediated through both peripheral and central nervous system (CNS) pathways. GLP-1 RAs directly stimulates POMC neurons and inhibits neuropeptide-Y (NPY) and Agouti-related peptide (AgRP) neurons in the arcuate nucleus resulting in a reduction in hunger and increases in fullness4. While there were studies which indirectly measured the changes of food preference and eating behaviour in humans after using GLP-1 RAs via visual analogue scales (VAS) or Patient's Experiences Questionnaires the investigators found there is a necessity to conduct the studies to do direct measurements of the changes of food preference and eating behaviour. Direct measures of an altered food selection in humans after using GLP-1 RAs have virtually not been performed likely due to the significant methodological and conceptual challenges they pose to researchers and study design. However, direct measures represent an essential component in the attempt to understand how GLP-1 RAs alters eating and diet selection which is the main reason of conducting this study. This innovative experiment will be a critical and a novel test of the explicit experience of humans with high-sugar high-fat fluids after using GLP-1 RAs and its potential role for the understanding of possible mechanisms determining post-treatment outcome such as weight loss.

NutriTrack: AI-Assisted Nutritional Tracking in the Obesity Clinic

NutriTrack is a digital health application designed to support nutritional and behavioral tracking in patients with obesity followed in an outpatient obesity clinic. The application allows patients to record food intake using food photographs, barcode scanning, or manual search, and to register behavioral variables related to eating episodes. This prospective, single-center, observational pilot study will evaluate the feasibility and usability of NutriTrack in 20 to 50 adult patients with obesity or overweight with comorbidities followed at the Obesity Clinic of Hospital Clínico San Carlos. Participants will use the application for 4 weeks as a complementary tool. The information generated by NutriTrack will be available to healthcare professionals as supportive information and will not replace clinical judgment or modify usual care decisions. The main outcome is usability measured using the System Usability Scale. Secondary and exploratory outcomes include agreement between artificial intelligence-based nutritional estimates and standard dietitian assessment, adherence to daily food logging, professional perceived clinical utility, changes in eating behavior and emotional regulation scales, and technical feasibility of data export.

Diet and WB-EMS Effects in Obesity

Obesity is a major global health problem associated with metabolic dysfunction, altered adipokine signaling, and impaired appetite regulation. Conventional weight loss strategies such as calorie restriction often result in compensatory physiological adaptations, including increased appetite and loss of lean body mass, which may limit long-term effectiveness. Whole-body electromyostimulation (WB-EMS) is an emerging, time-efficient intervention that induces simultaneous muscle activation and may improve metabolic health. However, the underlying molecular mechanisms, particularly the interaction between myokines and adipokines, remain insufficiently understood. This randomized controlled trial aims to investigate the effects of an energy-restricted diet combined with WB-EMS on myokine-adipokine interaction, appetite regulation, and body composition in obese individuals. Participants will be randomly assigned to either a diet-only group or a diet plus WB-EMS group for 8 weeks. Primary outcomes include changes in serum irisin levels. Secondary outcomes include myostatin, leptin, adiponectin, FGF-21, ghrelin, GLP-1, body composition parameters, and eating behavior. The findings of this study are expected to provide novel insights into the physiological and molecular effects of WB-EMS as a complementary strategy in obesity management.

Predicting Weight Loss After Pharmacological or Surgical Treatment in Patients With Obesity

As with other nutritional strategies, the clinical response to bariatric surgery can be highly variable, with weight regain being a frequent occurrence. Recent evidence on anti-obesity medication indicate similar inter-individual variability in clinical response. Among multiples factors, co-occurrence of eating disorders such as binge eating disorder has been implicated in insufficient clinical response. Improving our ability to predict how patients will respond to obesity treatment is necessary in order to tailor the care pathways we offer. The mechanisms involved in disturbances of eating behaviour before and after surgery remain largely unknown. This study aims to identify the predictive factors of weight loss after pharmacological or surgical treatment, as well as the cognitive and biological mechanisms that mediate this effect.

Effect of Meal Frequency on Diet Self-Efficacy and Perceived Stress in Women With Weight Cycling

The World Health Organization (WHO) defines obesity as abnormal or excessive fat accumulation in the body that may adversely affect health. In 2022, 1 in 8 people worldwide lived with obesity, while the adult obesity rate has more than doubled since 1990, and the adolescent obesity rate has quadrupled. Obesity is a risk factor for noncommunicable diseases such as type 2 diabetes, hypertension, cardiovascular diseases, cancer, and sleep apnea, and is associated with an increased risk of death. The treatment of obesity-related comorbidities, along with indirect costs resulting from lost productivity and premature death, contributes to the economic burden caused by obesity. Therefore, effective management of obesity is of critical importance for improving overall health outcomes and reducing the burden on healthcare systems. It has been demonstrated that a 5% reduction in body weight in individuals diagnosed with obesity can improve health outcomes, and this value has been established as a target standard for weight loss interventions. However, while dietary interventions can achieve clinically meaningful weight loss, weight regain is common due to a combination of low adherence to dietary strategies and compensatory physiological mechanisms that influence weight regain. Consequently, individuals may find themselves in a "weight cycle," losing weight and then regaining it. Weight maintenance is defined as intentional weight loss followed by the preservation of that loss for at least six months. It has been noted that the weight cycle complicates this process. The weight cycle defined as repeated periods of intentional weight loss followed by regain is considered a common yet poorly understood factor among obese individuals. The weight cycle is viewed as one of the major challenges in clinical obesity care. For this reason, it is emphasized that strategies aimed at preventing weight cycling or promoting weight maintenance have gained importance. Additionally, attention is drawn to psychological factors in eating behavior, with particular emphasis on the individual's self-confidence and stress levels being crucial for sustaining healthy eating behaviors. Individuals experiencing weight cycling often face challenges with diet adherence, sustainability, and stress management. Meal frequency strategies applied to these individuals can influence not only weight loss but also diet adherence and the psychological experience of the dietary process. Given the rise in obesity and obesity-related disorders, understanding the relationship between stress, self-efficacy, and food choice in young adulthood may offer insights into preventing adverse health outcomes in later life stemming from poor dietary habits. An appropriate meal schedule can help an individual adapt better to the diet and manage the process with less stress; thereby facilitating weight maintenance success and making healthy eating a lifestyle. However, in the treatment of obesity, data regarding different meal frequency approaches in dietary interventions remain controversial. The aim of this study is to examine the factors influencing the sustainability of the diet and the long-term maintenance of weight loss in individuals experiencing weight cycling. In this context, the effects of different meal frequencies on this process were evaluated; the study addressed not only physical outcomes but also psychological factors such as how individuals felt during the dietary process, their stress levels, and their self-confidence. Thus, the aim was to present a more comprehensive perspective by examining the relationship between meal frequency and weight management from both physiological and psychological dimensions.

Efficacy of Center-based Childcare to Mitigate Unhealthy Weight Gain in Preschoolers From Low-income Households During the Summer

Studies show that preschool-age children are especially vulnerable to accelerated weight gain during the summer, with those from low-income households (≤185% poverty level or Medicaid eligible - the target population for this study) exhibiting the greatest risk of unhealthy weight gain. Despite numerous interventions designed to prevent OWOB, none target preschoolers during summer. For families from low-income households, attending center-based childcare is associated with a lower risk of developing OWOB by 1st grade compared to attending home-based care. Center-based childcare lowers the risk of OWOB through daily rules/routines that promote healthy behaviors. For families from low-income households, publicly funded center-based childcares (e.g., needs-based pre-K, Head Start) typically operate on an academic/school 9-month calendar (Aug-May). During summer, fewer than 30% of preschoolers attend center-based childcare. For many preschoolers from lower-income households, summer may serve as an extended period away from formal center-based childcare, because the out-of-pocket expense may prohibit attendance. This may promote unhealthy behaviors and excessive weight gain. In the majority of US states, publicly funded center-based childcare during the academic/school year for families from underserved populations is free; however, center-based childcare during the summer is an out-of-pocket expense for many of these families. Despite parents' desire for childcare during the summer, a major reason children from low-income households do not attend center-based care during summer is cost. This creates unequal access to resources and likely exacerbates health disparities for families from low-income households. Using a structural intervention approach, this study will test the impact of providing free center-based childcare in the summer. This R01 will rigorously test the impact of providing free center-based childcare during the summer on weight status of preschoolers from low-income households (≤185% of poverty level or Medicaid eligible).

SHAPE-ENDO: Multimodal Pre-Surgical Optimization in Patients With Obesity and Early-Stage Endometrial Cancer (Phase 1)

SHAPE-ENDO is a prospective, single-center, low-intervention, non-randomized, single-arm clinical trial conducted at Hospital Universitari de Bellvitge (Barcelona, Spain). The study is designed to evaluate a protocolized multimodal pre-surgical optimization strategy in women with severe obesity (BMI ≥40 kg/m²) and atypical endometrial hyperplasia/endometrial intraepithelial neoplasia or early-stage, low-risk endometrioid endometrial cancer. The strategy is intended for selected patients in whom immediate surgery may be associated with increased perioperative risk due to obesity and comorbidities. Participants will receive a structured multimodal optimization program aimed at improving metabolic and functional status while maintaining local oncologic control. The multimodal strategy includes authorized treatments used according to clinical indication, product labeling, current guidelines, and physician judgment: semaglutide/GLP-1 receptor agonist therapy for metabolic optimization, local hormonal treatment with a levonorgestrel-releasing intrauterine device with or without oral progestins, structured nutritional intervention, adapted physical exercise, and scheduled clinical, imaging, and histological surveillance. The primary objective is to estimate the proportion of participants who achieve predefined pre-surgical optimization criteria after the multimodal strategy, including clinically relevant weight loss and/or reduction to BMI \<40 kg/m², absence of tumor progression, and acceptable anesthetic/surgical risk. Secondary outcomes include histological response, metabolic and anthropometric changes, treatment adherence, safety, health-related quality of life, feasibility of subsequent surgery, perioperative outcomes, and exploratory long-term survival outcomes. Participants will be followed during a 28-54 week optimization period. Long-term follow-up will assess recurrence, survival, quality of life, and metabolic outcomes. Exploratory adjusted comparisons may be performed against a historical cohort of patients with similar baseline characteristics previously treated at the same institution.

Effects of Different Fish Oil Types on Type 2 Diabetes Risk Factors in High-Risk Adults

The purpose of this clinical trial is to find out whether one type of fish oil works better than another at improving metabolic health in people who are at high risk of developing type 2 diabetes. Some metabolic problems-such as difficulty controlling blood sugar, unhealthy particles that transport cholesterol in the blood, and poor fat tissue function-can increase the risk of type 2 diabetes. This study aims to determine whether different types of fish oil can: 1. Improve how well the body produces insulin and responds to it, 2. Improve the quality of the particles that carry "bad" cholesterol in the blood, and 3) Improve the health and function of participants' fat tissue. To answer these questions, researchers will compare the effects of two types of fish oil: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These will be compared with corn oil, which is used as a placebo and does not contain EPA or DHA. When included in this study, participants will: A) Take softgel capsules containing EPA, DHA, or placebo (corn oil) every day for 12 weeks, B) Keep a daily log to record when they take their study softgels, and C) Visit the research unit six times, including one and a half days before and after the intervention, to complete specialized metabolic tests that are mostly only available in research settings.

Visceral Adipose Tissue and Liver Changes Associated With Semaglutide in CKD

Obesity is considered a global pandemic and is associated with various diseases and metabolic complications, such as type 2 diabetes mellitus, high blood pressure, cholesterol disorders, cancer, cardiovascular disease, and kidney disease. Obesity can affect the kidneys in two main ways: indirectly, through mechanisms related to diabetes mellitus and/or high blood pressure, and directly, through complex proteins called "adipokines," which are produced by adipocytes. Many of these adipokines are secreted by adipocytes under normal conditions, as they contribute to maintaining immune defenses and energy production. However, in obesity these adipokines acquire harmful properties and produce chronic inflammation in vital organs, such as the heart, blood vessels, the pancreas, and the kidney, leading to a deterioration in liver and kidney function. New drugs such as glucagon-like peptide-1 receptor agonists (GLP-1Ras / Semaglutide), are not only effective to regulate blood sugar levels, but they produce weight loss improving kidney and liver function. However, little is known about their specific effect on the adipose tissue. Therefore, studies focusing on how these drugs work in fat could help us understand how diseased adipose tissue can affect patients with heart, liver, and kidney disease. Investigators are asking patients who attend the diabetes clinics associated with the University of Alberta to join the study.
