This study is designed as a preliminary investigation to evaluate the weight-loss efficacy and safety of AKM Lab-01 in an overweight or obese population. It is an interventional, radomized, double-blind, placebo-controlled clinical trial. Participants who meet the eligibility criteria will be randomly assigned to receive AKM Lab-01 or a matching placebo. The intervention will be administered once daily for 3 months. Baseline metrics, along with blood, urine, and stool samples, will be collected from participants, before and after the AKM Lab-01 intervention. The analysis will focus on changes in body weight, blood lipids, blood glucose, and gut metagenomic profiles (from stool samples). Furthermore, metabolomic analysis of blood and stool samples will be conducted to explore the potential machanisms through which AMK Lab-01 influences body weight.

The goal of this observational study is to learn about the long-term effects on health and well-being of treatment for overweight in childhood or adolescence using the Children's Obesity Clinic Treatment protocol (the Holbæk Model) (HM). The study has two parts: * An active follow-up study, where participants are invited to take part in new measurements and questionnaires * A register-based study, which uses existing data on diagnoses, medication use, and school well-being The submitted protocol primarily focuses on the active follow-up study. The register-based study covers diagnoses, medication use, and school-related well-being and is described in the section "Detailed description". In the active follow-up study, researchers will examine: * Body measurements such as height, weight, and waist circumference * Body composition * Psychosocial well-being and mental health * Eating behaviors in young adults Participants will be followed for up to 20 years after treatment initiation. Where possible, results will be compared with a group of people of the same age from the same area who did not receive this treatment. This will help show whether their development differs from that of the general population. The aim is to use the findings to improve future follow-up care and support for people who were treated for overweight as children. The study includes two groups: 1. A treatment group of individuals treated at the Holbæk Pediatric Department between 2008 and 2025 2. A comparison group from the general population, recruited between 2010 and 2016 The study will take place in two phases: * A pilot phase (about 1.5 years) to test procedures and recruitment * A main phase (about 3 years) Participants are invited to one follow-up visit. During this visit: * Body measurements will be taken * Body composition will be assessed * Participants will complete questionnaires The study team will ensure that all participants are treated respectfully and without stigma. Flexible options, including home visits, are offered to make participation easier.

The purpose of this study is to learn whether following an online weight loss program with specific dietary and exercise goals (the 30-30-30 plan) can help improve weight loss and other markers of health when compared to an online weight loss program on its own.

This study builds on the knowledge that fasting provides metabolic health benefits and that prebiotic interventions can enhance the gut microbiome's metabolic output to likewise improve host health. Whether long-term fasting and dietary fibre interventions could be combined to achieve synergistic improvements in host metabolic health is however unknown. The goal is to provide a proof of concept in a human trial that supplementing 10±4 days fasting with dietary fibre synergistically improves metabolic outcomes via gut microbiome-mediated effects. To assess this, we aim to analyse gut microbiome changes, functional outputs, and key metabolic markers such as butyrate production, glycaemic control and ketosis. The randomised controlled trial includes 75 participants and has two arms: one involving fasting with fibre supplementation (n = 50) and one involving fasting without fibre supplementation (n = 25). All participants will undergo a fasting period of 10±4 days according to the Buchinger Wilhelmi protocol, followed by a stepwise reintroduction of food of up to 4 days. As dietary fibre we will use maize-derived resistant starch type IV, selected based on its ability to stimulate beneficial gut microbes like Oscillibacter and corn starch as placebo. Two main visits will be conducted: before and at the end of the fasting period. During these visits, blood and stool samples will be collected, and questionnaires will be completed. Additionally, daily measurements of anthropometric parameters and well-being will be recorded. Stool samples will also be collected one month afterwards as a follow-up. Participants' metabolic health will be evaluated through various clinical parameters (e.g., body measurements, blood pressure, glycaemic control, ketones, well-being). Additionally, multi-omics data, including metagenomics and metabolomics, will provide insight into the composition of the microbiome, as well as its outputs and functions. Furthermore, the effects of fasting on extracellular vesicles in blood will be explored.

The menopausal transition is associated with significant hormonal changes that negatively impact many women's quality of life. Vasomotor symptoms, sleep disturbances, mood changes, and genitourinary symptoms are frequently reported during this period. Concurrently, there is a tendency toward increased body weight and fat redistribution, specifically central fat accumulation, which raises the risk of metabolic diseases. Although hormonal therapy is effective, it is not suitable for all women, necessitating the consideration of non-pharmacological strategies as therapeutic alternatives. Scientific evidence indicates that healthy dietary patterns and weight loss are associated with reduced menopausal symptom severity. The objective of the research is to evaluate the effects of a dietary intervention based on the guidelines of the Dietary Guidelines for the Brazilian Population (GAPB) on the reduction of menopausal symptoms. A randomized clinical trial will be conducted to assess whether improving dietary quality and reducing body weight contribute to alleviating menopausal symptoms. Participants will be assigned to two groups: a control group (CG) and an intervention group (IG). Both groups will receive nutritional guidance based on the GAPB; however, the CG will receive the guidelines in printed format, whereas the IG will receive them through group sessions. The study will include perimenopausal or postmenopausal women who are overweight or obese and experiencing menopausal symptoms. Validated instruments will be administered at the beginning and end of the study to assess dietary patterns, menopausal symptoms, and nutritional status.

The goal of this clinical trial is to assess whether TRPTI™ supplementation affects GLP-1 and related metabolic markers in generally healthy adults who are overweight or obese (BMI 25.0-34.9 kg/m², aged 30 years and older). Researchers will compare TRPTI™ 150 mg to a matching placebo capsule to see if TRPTI™ produces a meaningful difference in GLP-1 response and associated metabolic and appetite-related markers over 8 hours. Participants will attend two 9-hour clinic visits (crossover design, with a minimum 6-day washout between visits).

This pilot study will evaluate whether brief bouts of stair climbing performed throughout the day for two weeks can improve metabolic health, cardiovascular fitness, and other health-related outcomes in adults with overweight or obesity who do not regularly exercise. Participants will complete approximately 6-8 brief stair-climbing "exercise snacks" per day for 14 days, with each bout consisting of approximately 60 total stair steps performed at a challenging but safe self-selected pace. Participants will complete baseline and post-intervention assessments at Saint Louis University. These assessments will include continuous glucose monitoring and standardized meal testing to evaluate glucose responses, as well as measures of aerobic fitness, anaerobic power, body composition, waist circumference, and muscular strength. The study will also evaluate adherence, perceived exercise intensity, and the feasibility of incorporating brief stair-climbing bouts into daily life.

A study of ALV-100 to assess efficacy, safety and tolerability among participants with overweight or obesity who have previously achieved a body weight reduction of ≥10% while treated with incretin-based therapies.

This single-center, stratified randomized double-blind trial tests tegileridine, a new pain drug, for pain relief after weight-loss surgery. Researchers will compare tegileridine with standard opioid pain medicine. Eligible patients having bariatric surgery will be randomly assigned to one of the two treatment groups. Patients and study teams will not know which treatment each participant receives. Participants will be grouped based on whether they have obstructive sleep apnea (OSA). The primary measurement is postoperative recovery quality in the first 24 hours after surgery using the QoR-15 survey. The study will also track pain scores, rescue pain medication use, and drug side effects for 7 days after surgery. There is no guaranteed benefit for participants. Study pain medicines may cause side effects. Doctors will provide rescue treatment for uncontrolled pain.

This multicenter, prospective, randomized, blinded, parallel-group controlled trial will evaluate the effects of standardized large yellow tea extract on glucose and lipid metabolism in overweight adults with elevated triglyceride levels. Approximately 138 participants aged 18 to 60 years will be enrolled at three study centers in China and randomly assigned in a 1:2 ratio to a placebo control group or a standardized large yellow tea extract group. Participants will receive the assigned intervention for 12 weeks, together with standardized lifestyle guidance. The primary objective is to compare the change in fasting triglyceride levels from baseline to week 12 between the two groups. Secondary objectives include evaluating changes in other lipid parameters, glucose metabolism, body weight, body mass index, waist circumference, blood pressure, and safety and tolerability. Exploratory analyses will assess plasma and/or urine metabolomic profiles and potential biomarkers related to response to the tea intervention. Participants will also be followed through week 24 for longer-term safety assessment and changes in glucose and lipid metabolism.

This study focuses on promoting physical activity (PA) through the implementation of a Community Physical Exercise Program for Chronic Diseases (CPEP-CD), targeting individuals aged 50 years and older with at least two of the following conditions: cardiovascular and/or cerebrovascular disease or risk (CVD), overweight, diabetes mellitus (DM), and musculoskeletal diseases. The primary objective is to improve muscle and cardiorespiratory health and well-being, while also contributing to a more objective and evidence-based exercise prescription for these pathological conditions. Population ageing is a global challenge associated with an increased prevalence of chronic diseases that compromise quality of life (QoL). A sedentary lifestyle is linked to declines in muscle function and cardiorespiratory fitness and is considered a major risk factor for morbidity and mortality. Consequently, physical exercise is widely recommended as a key non-pharmacological intervention across multiple chronic diseases. According to World Health Organization (WHO) guidelines, regular PA is a protective factor in the prevention and management of non-communicable diseases, including cardiovascular and cerebrovascular diseases and DM. In addition, PA provides mental health benefits, supports healthy weight maintenance, and enhances overall well-being. In adults, regular PA is associated with reductions in all-cause mortality, cardiovascular mortality, and the incidence of hypertension. Within this context, the aim of this project is to implement a community-based physical exercise program for individuals with chronic disease and multimorbidity, focusing on CVD and cerebrovascular disease or risk, DM, and OA. The program integrates existing exercise prescription guidelines while personalizing exercise progression according to both disease-specific and multimorbidity profiles. The primary outcomes include improvements in cardiorespiratory fitness, muscular strength, bone health, functional capacity, and QoL. Additionally, through individualized training monitoring, this study seeks to establish an exercise prescription tailored to the most prevalent combinations of chronic diseases, thereby providing more objective and practical guidance for family physicians, exercise professionals, and rehabilitation specialists, and supporting more personalized and targeted exercise-based strategies for chronic disease prevention and management.

The goal of this clinical trial is to find out whether exercising at the right time of day, based on a person's natural body clock, leads to greater health benefits in people living with prediabetes. The main question it aims to answer is whether doing a single session of exercise in the morning or in the evening affects how the body handles sugar differently in adults with prediabetes who have an extreme natural body clock. This will be done by comparing three conditions (no-exercise, morning exercise, and evening exercise) within the same participant. Each condition will be tested on a different day, with at least 14 days between the test days. During the no-exercise test days, participants will come to the study centre and will only be allowed to do sedentary activities (e.g. office work, reading, or screen time). During the morning exercise test days, participants will perform an exercise session at 9:00 am that involves short periods of very hard effort followed by short rest periods. Whereas for the evening exercise test days, the same type of exercise will be performed at 5:00 pm.

This study is a randomized, double-blind, placebo-controlled, multiple-dose, dose-escalation phase I clinical trial aiming to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity of MWN105 injection in Chinese non-diabetic overweight or obese participants. The study plans to enroll 36 male and female participants. Three dose groups were preset, with 12 participants in each. They were randomly assigned to receive MWN105 injection or placebo at a ratio of 5:1 and were administered the treatment in a titration manner, once a week, with a dose increase every two weeks until reaching the target dose. The administration lasted for 8 weeks. The study consists of a 2-week screening period, an 8-week administration/observation period, and a 4-week follow-up period, totaling 14 weeks. The primary endpoint is the incidence of adverse events. Secondary endpoints include pharmacokinetics, pharmacodynamics, and immunogenicity.

The increasing prevalence of obesity, its serious health consequences, and the substantial economic burden on healthcare systems underscore a pressing need for effective, long-term prevention strategies that can be implemented in primary care. Emerging evidence suggests that combining lifestyle modification with dietary supplements and pharmacological treatment may enhance and prolong intervention effects, yet comparative long-term data on their individual and combined efficacy are limited. Therefore, this study aims to evaluate the independent and additional effects of a comprehensive lifestyle intervention, a mushroom-based dietary supplement, and bupropion treatment over 12 months, to identify more effective and sustainable strategies for obesity prevention in overweight and obese adults.

This study is a multicenter, randomized, double-blind, placebo-controlled, single and multiple ascending-dose phase 1 clinical trial aimed at evaluating the safety, tolerability, PK, PD, and immunogenicity of MWN110 Injection in healthy participants and overweight or obese participants. The study consists of two parts: Part 1, a single ascending dose (SAD) study in healthy participants with 8 dose cohorts; and Part 2, a multiple ascending dose (MAD) study in overweight or obese participants with 3 dose cohorts, with a dosing frequency of once weekly or once every 4 weeks. Approximately 103 participants will be enrolled. The primary endpoint is safety and tolerability, assessed by adverse events, vital signs, physical examination, laboratory tests, 12-lead electrocardiogram, and ophthalmic examination. Secondary endpoints include single-dose and multiple-dose PK parameters, PD parameters (body weight, BMI, waist circumference, muscle mass, body fat percentage, visceral fat, subcutaneous fat, bone mineral density), and immunogenicity (anti-drug antibodies).

This is a phase 3, multicenter, randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of MWN109 injection in non-diabetic participants with overweight or obesity. Approximately 760 participants will be enrolled. All participants will be stratified by gender (male or female) and baseline BMI level, and then randomized 1:1:1:1 to 4 treatment groups, with 190 participants per group. All treatment groups will implement dose titration to achieve the target dose. The study comprises a screening period of up to 2 weeks, a 52-week treatment period, and a 4-week follow-up period, for a total study duration of 58 weeks. The primary endpoints are the percentage change in body weight from baseline and the proportion of participants achieving ≥5% weight reduction from baseline at Week 52. The secondary endpoints include the proportions of participants achieving ≥10% and ≥15% weight reduction from baseline, as well as the change from baseline in waist circumference at Week 52.

The goal of this 16-week randomised, placebo-controlled parallel study is to investigate the effect of a newly formed probiotic supplement on satiety and gut microbiota composition in healthy men and women with overweight or obesity form 20-70 years old. The main question it aims to answer is: Does the probiotic supplement increase feelings of satiety and alter gut microbiota composition? Participants will: * Receive a daily dose of 6 g probiotic supplement (packed in sachets of 3 g) or placebo for 16 weeks. * Visit the research unit 3 times at baseline, week 8 and week 16 of the intervention for blood draws and delivering fecal samples. * Keep a study diary to report deviations from their daily habits and fill in food questionnaires.

The goal of this observational pilot study is to evaluate whether a participant-mediated, direct-to-participant research approach is a feasible and effective way to collect health data from adults living with obesity in England, France, and Germany. This approach allows participants to take part remotely and to help researchers access their medical records using their data access rights, while also providing information directly through an online questionnaire. The main questions it aims to answer are: 1. Can medical records be successfully obtained through participant-authorized data subject access requests (DSARs), and how long does the process take? (In France, DSAR Authorization Form is not applicable and participants are asked to directly share their medical records of interest.) 2. How well do healthcare providers comply with requests for medical records? (In France, DSAR Authorization Form is not applicable and participants are asked to directly share their medical records of interest. Therefore, their healthcare providers are not contacted.) 3. Is the information collected through this approach complete and of sufficient quality for research purposes? 4. How closely does information reported by participants match the information contained in their medical records? 5. Are there differences in outcomes between countries and regions? Researchers will also explore the demographic, clinical and socio-economic characteristics of participants, assess health-related quality of life, evaluate experiences related to "food noise", and compare quality-of-life results across countries. There is no comparison group or study treatment, as this is an observational study. Participants will: * Provide electronic informed consent to participate in the study. * Authorize requests for their medical records using their legal right to access personal health information (DSAR). (In France, DSAR Authorization Form is not applicable and participants are asked to directly share their medical records of interest.) * Complete an online questionnaire about their health, quality of life, and experiences related to obesity. * Allow researchers to combine information from questionnaire with data obtained from their medical records. * Participate entirely remotely through the IQVIA Health Research Space (HRS) platform, with no study site visits required. Participation lasts for up to 90 days and includes completion of questionnaire and the medical record retrieval process. The study plans to enroll approximately 105 participants, with around 35 participants in each participating country.

This study aims to evaluate the effects of antioxidant-rich supplementation on skin carotenoid status, antioxidant status, and cardiometabolic health in overweight and obese individuals. The study may provide additional scientific evidence to support the further refinement of current dietary and nutritional recommendations.

The study is observational and single-center and involves (i) the establishment of a retrospective and prospective data collection, and (ii) the development of prognostic and predictive models of response to obesity therapies using statistical modeling and machine learning techniques, exclusively for research purposes. Data collection will be carried out for each patient diagnosed with obesity or overweight whose first visit to the center occurred from January 1, 2000 up to the start of the study, as well as for patients accessing the center during the subsequent 5 years, including patients who died or were lost to follow-up. With respect to the primary objective, an interim analysis is planned on the retrospective cohort only, once the collection of data already available at study start has been completed for patients with at least 5 years of follow-up. Data related to instrumental and laboratory examinations and therapeutic interventions, including pharmacological treatments and group-based educational and behavioral therapies, conducted in accordance with routine clinical practice and the most recent relevant national and international guidelines, will be extracted from the electronic health records routinely used at the study center.

The primary objective of this study is to investigate the effects of a multidisciplinary intervention, including a targeted adapted physical activity program, on lipid oxidation during a walking exercise in women with overweight or obesity, with or without polycystic ovary syndrome. Specifically, the study aims to compare changes in lipid oxidation before and after the intervention between women with polycystic ovary syndrome and those without polycystic ovary syndrome. The secondary objectives are to assess the impact of polycystic ovary syndrome on several physiological and metabolic parameters in women with overweight or obesity. These include: (i) resting energy metabolism; (ii) resting blood pressure and heart rate; (iii) energy expenditure, energy cost, and heart rate during a walking exercise; (iv) body composition, glycemic and lipid profiles, and circulating levels of sex hormones and adipokines; (v) movement behaviors; and (vi) physical fitness. In addition, the effect of the multidisciplinary intervention, including the adapted physical activity program, will be evaluated on these same outcomes: (i) resting energy metabolism; (ii) resting blood pressure and heart rate; (iii) energy expenditure, energy cost, and heart rate during walking exercise; (iv) body composition, glycemic and lipid profiles, and concentrations of sex hormones and adipokines; (v) movement behaviors; and (vi) physical fitness, in women with overweight or obesity, with or without polycystic ovary syndrome.

SucroMet is designed to evaluate how adding two commonly used sweeteners-sucrose (table sugar) and sucralose (a low-calorie sweetener)-at low and high doses may influence glucose regulation, including insulin resistance and fasting plasma glucose, in adults aged 18 to 65 years with normal weight, overweight, or obesity. The low-dose intervention consists of 5% of the Estimated Energy Requirement (EER) from sucrose or 5 sucralose tablets per day (approximately 33.35 mg/day of sucralose). The high-dose intervention consists of 10% of EER from sucrose or 10 sucralose tablets per day (approximately 66.7 mg/day of sucralose). These doses maintain the planned 1:2 exposure ratio between the low- and high-dose intervention groups. Before the intervention begins, participants' habitual dietary intake is assessed and, when necessary, minor dietary adjustments are made to support a stable overall eating pattern while maintaining energy intake. Participants then complete a four-week run-in period during which these recommendations are followed, and dietary records are used to verify dietary stability before the intervention starts. Participants will consume the assigned sweetener incorporated into foods or beverages that they already consume as part of their habitual diet, without substantial changes to their usual eating patterns. The intervention includes two consecutive 12-week phases, one involving solid food intake and the other involving liquid intake, separated by a two-week washout period. This design allows evaluation of the effects of sweetener type, dose, and mode of consumption. The primary outcomes are changes in glucose regulation, including fasting plasma glucose and insulin resistance assessed by HOMA-IR. Secondary outcomes include changes in body composition, anthropometric measurements, blood pressure, routine biochemical parameters, gut microbiota composition, DNA methylation patterns in peripheral blood cells, and biomarkers related to inflammation, oxidative stress, and metabolomic profiles measured in blood and urine. Participants will attend scheduled study visits for anthropometric assessments, dietary evaluations, and biological sample collection. Blood, urine, and stool samples will be obtained at baseline and after each intervention phase. The study aims to address the following questions: 1. Do metabolic responses to sucrose and sucralose, including changes in insulin resistance (HOMA-IR) and fasting plasma glucose, differ according to participants' body mass index (BMI)? 2. Do low and high doses of sucrose and sucralose differentially affect glucose regulation, body composition, and metabolic health? 3. Does the mode of intake (solid versus liquid) influence changes in gut microbiota composition? 4. Are changes in DNA methylation patterns in peripheral blood cells associated with the consumption of sucrose and sucralose at different doses and in different forms? 5. Do different doses of sucrose and sucralose influence biomarkers related to inflammation, oxidative stress, and metabolomic profiles?

This study is a two-arm pilot randomized controlled trial designed to evaluate the feasibility and preliminary effects of an Acceptance and Commitment Therapy (ACT) theory-based mobile application integrated with a smartphone pedometer plus health education on weight self-stigma and lifestyle behaviors among overweight or obese adults. A total of 60 participants will be recruited and randomized 1:1 to the intervention (ACT-based app + pedometer + health education) or control condition. Outcomes will be assessed at baseline (T0), immediately after intervention (T1), and at 1 month after intervention (T2) and 3 months after intervention (T3) following intervention initiation. The primary outcomes are body weight (weight loss) and weight self-stigma measured; secondary outcomes include eating behavior, physical activity level, and quality of life. Analyses will include per-protocol evaluation using linear mixed-effects models to test group, time, and group-by-time effects on primary and secondary outcomes, with intention-to-treat analyses conducted as sensitivity analyses using multiple imputation for missing weight and weight self-stigma data. Findings will inform the design of a future definitive trial and contribute evidence on eHealth approaches to reducing weight-related stigma and supporting healthier lifestyles.

This is a two-part study, intended to investigate the safety, tolerability, characteristics of PK and PD of single SC dose of SRSD384 alone in overweight or obese participants (Part A) and in combination with tirzepatide in overweight or obese participants with T2DM (Part B).

The goal of this clinical trial is to learn which dose of study drug IBIO-600 has the right balance of safety, tolerability and impact on body composition in overweight and obese adult participants.
