NCT07464223
This study evaluates changes in pancreatic fat and recovery of pancreatic function in obese patients undergoing laparoscopic sleeve gastrectomy (LSG), a weight-loss surgery. Obesity can cause fat to accumulate in the pancreas, which may impair insulin production and lead to type 2 diabetes. This study uses magnetic resonance imaging (MRI) to measure pancreatic fat before and after surgery to understand how weight loss affects pancreatic function. About 50 obese patients (BMI \> 32 kg/m²) aged 16-60 years who are scheduled for LSG will be enrolled. Participants will undergo MRI scans of the pancreas and blood tests before surgery and at 1, 3, and 6 months after surgery. The MRI uses a safe, non-invasive technique called Dixon imaging to measure fat content in different parts of the pancreas (head, body, and tail). Blood tests will measure fasting glucose, insulin, C-peptide, and HbA1c to assess pancreatic function. The study aims to determine whether reduction in pancreatic fat after weight-loss surgery is associated with improved insulin secretion and reduced insulin resistance. This information may help doctors better understand how bariatric surgery improves metabolic health and guide postoperative patient management. Participation involves no additional risk beyond routine clinical care. All MRI scans and blood tests are part of standard postoperative monitoring for bariatric surgery patients.
NCT07461740
The aim of this clinical trial is to evaluate the effect of mindful eating training on mindful eating behaviors and hedonic hunger levels in adults with obesity. The primary research questions are as follows: * Does mindful eating training combined with a weight loss diet improve mindful eating behaviors? * Does mindful eating training combined with a weight loss diet reduce hedonic hunger levels? * Does mindful eating training combined with a weight loss diet lead to changes in anthropometric measurements? Researchers compared participants receiving a weight loss diet alone (control group) with those receiving mindful eating training in addition to a weight loss diet (intervention group) to determine differences in mindful eating behaviors, hedonic hunger scores, and anthropometric measurements. Participants who are already enrolled in a weight loss diet program was invited to participate in a mindful eating training program.
NCT07455630
Obesity is a major public health problem worldwide and an established risk factor for cardiovascular disease. In individuals with obesity or overweight, systemic inflammation and endothelial dysfunction contribute to myocardial hypertrophy, ventricular remodeling, and alterations in cardiac morphology and function. Weight loss has been shown to improve metabolic and hemodynamic parameters; however, evidence regarding structural and functional cardiac reversibility remains limited. This prospective single-center cohort study aims to evaluate changes in cardiac morphology and function (assessed by cardiac magnetic resonance imaging and echocardiography), as well as changes in inflammatory and cardiac biomarkers, in patients with obesity or overweight and cardiovascular risk factors who achieve at least a 10% reduction in body weight through pharmacological or non-pharmacological interventions.
NCT07225426
The purpose of this study is to determine the feasibility of providing personalized incentives for dietary self-monitoring and/or interim weight loss to people enrolled in a weight-loss program
NCT07423780
This study will examine within-subject (pre-post) changes in muscle quality, body composition, and functional response following a concurrent exercise program (aerobic + resistance training) in individuals after bariatric surgery. This is a single-center, prospective, longitudinal, quasi-experimental study with a one-group pre-post design. Men and women aged 18 to 60 years who have undergone sleeve gastrectomy or gastric bypass at BUPA Clinic Santiago, are PAD voucher beneficiaries, and have a medical indication for metabolic rehabilitation will be included. Participants will enter the study from postoperative week 4, when the baseline assessment will be performed and the program will begin. The intervention will consist of a 5-week supervised program delivered as two in-person sessions per week (10 sessions in total), each lasting approximately 60 minutes; additionally, participants will be prescribed one autonomous home-based session per week guided by an exercise plan provided by the responsible professional (as a complementary recommendation, not systematically recorded for adherence calculation). After the program, a 1-week period without supervised sessions will be observed, and the final assessment will be performed during the following week. Therefore, outcomes will be measured at two time points: baseline (pre-intervention) and 7 weeks after baseline (after 5 weeks of exercise and 1 week of rest). Adherence will be assessed exclusively as the attendance rate to the 10 supervised in-clinic sessions during the 5-week intervention period, calculated as: adherence (%) = (attended supervised sessions / 10) × 100; for descriptive purposes, adherence will be categorized as high (≥80%), moderate (60-79%), or low (\<60%). Exploratory analyses will examine the association between adherence (%) and the magnitude of pre-post changes in primary outcomes using multivariable linear regression models, adjusting for weight change during the intervention period (Δweight = post-intervention weight - baseline weight). Muscle quality will be assessed using musculoskeletal ultrasound of the rectus femoris (Philips Lumify) with ImageJ image analysis, including thickness measures and parameters related to fat infiltration/echo intensity and area according to a standardized protocol. Body composition will be assessed by bioelectrical impedance analysis (InBody S10). Functional response will be measured using the One-minute Sit-to-Stand Test (1min-STST), with vital signs and perceived exertion (modified Borg scale) recorded as appropriate. Quality of life will be assessed as a secondary outcome using the Moorehead-Ardelt II questionnaire. The expected results will provide clinically relevant evidence on within-subject changes and on the association between adherence to a concurrent exercise program and muscle-related outcomes, supporting optimization of postoperative metabolic rehabilitation after bariatric surgery.
NCT07443956
This is a trial to find out how weight loss (achieved by the use of tirzepatide) or ixekizumab treatment affects the characteristics of skin, joint and fat tissues in patients with Psoriatic Arthritis, Psoriasis and obesity/overweight BMI \>=27. Participants will be allocated either Tirzepatide, Ixekizumab or both. Samples of joint tissue, fat and skin will be taken at the start of the study and week 12. Blood and urine samples will also be taken. The primary objective will be to assess the changes seen in the joint, fat and skin tissue samples 12 weeks after starting the medications (additional analysis will be done on the optional 36 week samples). Secondary objectives will be * To assess the changes seen in blood 4, 12, 36 and 52 weeks after starting the medication. * To compare the changes seen in tissue and blood between Ixekizumab and Tirzepatide/Weight loss. * To see how the changes seen in the tissue relate to weight loss.
NCT07430007
Atrial fibrillation (AF) is the most common cardiac arrhythmia and is strongly associated with obesity and excess body fat. Lifestyle interventions, including exercise and dietary modification, may reduce AF burden, but long-term randomized controlled trial evidence with objective AF burden assessment and advanced cardiac imaging is limited. The MOVE-AF trial is a randomized controlled trial designed to evaluate whether a 12-month tailored exercise and dietary lifestyle intervention, compared with usual care, reduces atrial fibrillation burden and symptom severity and decreases cardiac and total body fat mass in overweight and obese adults with paroxysmal or persistent AF.
NCT07430059
The study will evaluate the safety, tolerability and drug levels of a semaglutide implant placed just under the skin for a period of 4 weeks compared to 4 weekly injections of semaglutide (Wegovy) in overweight/obese participants who are otherwise healthy..
NCT07425093
This study examines the relationship between walking exercise, body fat percentage changes, and brain gray and white matter volumes in overweight and obese adults with headache complaints. Participants with a Body Mass Index (BMI) of 25 or above will be divided into two groups: one receiving a diet program combined with a 12-week walking exercise regimen, and a control group receiving diet alone. Both groups will undergo brain MRI scans and body composition measurements at baseline and after 12 weeks. The study aims to determine whether exercise-induced reductions in body fat percentage have a measurable impact on brain structure, specifically gray and white matter volumes. Blood tests will monitor metabolic markers throughout the intervention. This research may contribute to understanding how different types of exercise affect brain health and inform the development of more effective treatments for obesity-related neurological changes.

NCT07414043
The study is multicenter and observational, consisting of a cross-sectional phase (V0) in which data will be collected from patients who are offered drug therapy, and a prospective longitudinal phase in which only patients who agree to start drug therapy for obesity will be involved
NCT07409831
The goal of this clinical trial is to evaluate whether combining a six-month structured lifestyle intervention (physical activity and nutrition) with incretin-based weight-loss medication improves preservation of muscle mass and physical function in adults living with obesity, compared with medication alone, and to assess the feasibility of a collaborative hospital-community care model. This one-year pilot study will recruit 120 adults aged 18-70 years with obesity (BMI ≥30 kg/m² or ≥27 kg/m² with at least one comorbidity) receiving routine obesity care at the Institut universitaire de cardiologie et de pneumologie de Québec - Université Laval. All participants will initiate physician-prescribed incretin-based therapy as part of standard care. The intervention group will receive medication plus a six-month structured lifestyle program delivered in collaboration with an exercise facility, including supervised strength-focused exercise and bi-monthly nutrition counseling, followed by a six-month consolidation phase. The control group will receive medication alone. Outcomes will be assessed at baseline and at 3, 6, and 12 months. Participants will be randomly assigned in a 1:1 ratio to either the medication-only group or the combined medication and lifestyle intervention group. Participants randomized in the medication only group will receive a personalized consult with both a registered dietician and kinesiologist at the end of the study.

Obesity is a multifactorial disease which has become a public health problem with increasing frequency, especially in recent years. Obesity causes many health problems with its negative effects on organs, systems, and psychosocial status. It is a serious risk factor for many diseases and also causes a significant increase in morbidity and mortality in these diseases. Although dietary treatments and medical treatment options are frequently used, surgical options are still the most effective treatment. Bariatric and metabolic surgical techniques are frequently applied, especially in patients with advanced obesity and obesity-related comorbidities. The most commonly applied bariatric metabolic surgical techniques, as in our clinic, are laparoscopic sleeve gastrectomy (LSG) and Roux-en-y gastric bypass procedures. The role of adipokines, secreted from adipose tissue and thought to play a role in the development of obesity, is quite important in the obesity mechanism, as they are effective not only in energy processes but also in metabolic processes. These adipokines secreted by adipose tissue play an active role in many mechanisms in the body, including vasoactivity, oxidative processes, immunity, lipid and glucose metabolism. Adipokines function actively in many target organs such as the pancreas, liver, and brain. Isthmin, a relatively new adipokine expressed from brown and white adipocytes, also affects many systems like other adipokines. Studies have shown that Isthmin plays an active role in glucose and lipid metabolism, and it has been reported to play a role in many metabolic processes, from insulin resistance to hepatic steatosis. The aim of this study is to investigate whether isthmin levels change before and after surgery in patients undergoing LSG for severe obesity, given that isthmin is thought to be associated with obesity and insulin resistance, particularly by affecting the appetite center in metabolism.
NCT07332741
The goal of this clinical trial is to treat both hypertension and obesity in adults using a food is medicine framework. Participants will be randomized 1:1 to FIM+DASH or usual-care control. The 24-week trial includes a 12-week FIM+DASH intervention followed by a 12-week maintenance period and leverages existing partnerships with community-based organizations for home food delivery and culinary skill-skill building. The main questions it aims to answer are: (1) What is the effect of FIM+DASH vs. usual care control on blood pressure? (2) What is the effect of FIM+DASH vs. usual care control on DASH diet adherence (diet quality), body weight, and waist circumference? (3) How to identify factors associated with the sustainability and scalability of FIM+DASH in real-world settings?
NCT07330297
This study aims to develop a non-invasive diagnostic method for metabolic syndrome (MetS) and metabolically healthy obesity (MHO) through analysis of exhaled air. Using proton-transfer-reaction mass spectrometry combined with machine learning algorithms, we will characterize volatile organic compound profiles in 300 participants across three groups: MetS patients, MHO patients, and healthy controls. The primary goal is to create and validate a classification model capable of accurately differentiating these metabolic states based on breath analysis.

NCT07284108
Infants from low-income families are at increased risk for obesity, but obesity prevention programs tailored specifically to the needs of these infants are lacking. Our team developed Healthy Eating for My Infant (HEMI) to address the specific obesity risk factors, barriers to health behaviors, and needs articulated by community members and low-income families (e.g., maternal mental health, realistic feeding options within the context of food insecurity). The current study will examine the feasibility and acceptability of HEMI delivered via home visiting, as well as preliminary efficacy for improving infant growth trajectories, diet, and parenting/feeding factors related to future obesity risk among infants from low-income families.
NCT07217756
The goal of this prospective observational study is to assess the influence of increased body mass index (BMI) on various oral health and orthodontic-related parameters in adolescents undergoing orthodontic therapy (OT) with braces. These parameters include gum inflammation, tooth decalcifications/discolorations, tooth alignment of lower incisors, and various inflammatory and microbiological parameters in the collected saliva and gum fluid of the patients. The primary purpose is to assess if an increased BMI is a risk factor for oral inflammation in adolescents undergoing OT. The main questions it aims to answer are: 1. Do patients with an increased BMI undergoing OT demonstrate increased microbial counts in the saliva compared to patients with normal BMI? 2. Do patients with increased BMI undergoing OT demonstrate increased gum inflammation, tooth discolorations, and higher levels of inflammatory markers in the saliva and gum fluid samples compared to patients with normal BMI? This study will include 2 study groups (patients with increased BMI-test group, and normal weight patients-control group). The participants will be asked to complete a study questionnaire, which will collect information regarding their demographics, their family socioeconomic and educational status, dietary habits, and oral health-related quality of life. The participants will also receive an oral examination (evaluation of their gum health), and they will have their intraoral photos taken, as well as an impression of their lower teeth (to create dental models). A saliva sample will be obtained by asking patients to passively "drool" in a tube, and a gingival fluid sample will be collected from the gums of the lower anterior teeth using thin paper strips. All these study procedures will be conducted at baseline (T1: before bonding of braces), and at an approximately 6-month follow-up visit (T2). Comparisons of these outcomes will be conducted between the two groups and across timepoints.
