Active clinical trials for "Obesity"

A prospective, randomized, placebo-controlled, double-blind study that aims to evaluate the effects of combined vitamin D3 and K2-MK7 supplementation on vascular function, sympathetic tone, metabolic biomarkers and inflammatory factors in a population of overweight or obese adults and deficient or insufficient serum levels of vitamin D.

This study will evaluate the effectiveness of the Bright Bodies intervention in improving body mass index (BMI) among 8-12 year-old children with obesity simultaneously with the impact of the implementation strategy on adoption, reach, fidelity, cost, and maintenance of the intervention in three heterogenous settings serving patients disproportionately affected by obesity.

The overall aim is to investigate effects of acute exercise on ad libitum energy intake and study whether this differs between morning and evening in individuals with overweight/obesity with or without type 2 diabetes (T2D). Furthermore, the aim is to examine the role of hedonic and homeostatic drivers of appetite control in obesity and T2D in the context of meal and exercise timing.

The purpose of this research is to gather information on the safety and effectiveness of Endoscopic Sleeve Gastroplasty (ESG) for weight loss in a population of obese ulcerative colitis (UC) patients undergoing colectomy with eventual Ileal Pouch Anal Anastomosis (IPAA) compared to counseling on diet and lifestyle interventions alone.

It is estimated that by 2030 one in five women and one in seven men will be obese, equivalent to more than 1 billion people around the world. It should be noted that the largest number of people with obesity live in countries with low and moderate-income. In 2019, more than 160 million years of healthy life were lost in the world, due to a high body mass index (BMI), this represents more than 20% of all years of healthy life lost due to chronic diseases. Therefore, it is essential to stop the increase in obesity and reduce it at all ages, which demands comprehensive actions at the global level. Scientific evidence suggests that people with a normal BMI, but with abdominal obesity, have a higher mortality risk compared to those with a similar or even higher BMI. In addition, visceral adiposity has been associated with worse survival and with colorectal cancer. Several methods of physical exercise have been used to counteract the adverse effects of obesity, including high-intensity functional circuit training (HIFCT). Scientific evidence indicates that HIFCT reduces fat mass, body mass, BMI, and waist circumference and improves muscle strength, maximal oxygen uptake, and health-related quality of life in overweight, obese, inactive, and with other diseases. However, no research assessed intra-abdominal fat (IAF), which, more than subcutaneous fat, is associated with cardiovascular risk factors. In addition, these studies had important methodological limitations. Therefore, the primary purpose of this study is to identify the effect of two HIFCT protocols, prolonged load (HIFCT-P) and short load (HIFCT-S), performed in a virtual environment for ten weeks on intra-abdominal fat in people between 18-40 years-old with abdominal obesity.

The goal of this single-blind randomized placebo-controlled trial is to test the effects of an oral ketone supplement on appetite, cognition, metabolism, and cardiovascular function in individuals with obesity and insulin resistance. The main question[s] it aims to answer are: Does taking the ketone supplement reduce appetite and improve cognition? How does the ketone supplement alter metabolism and cardiovascular function? Participants will be asked to consume a randomly assigned ketone ester supplement or a placebo and testing will be done to see how the supplement affects the following compared to a placebo: appetite, cognition, metabolism cardiovascular function Researchers will compare individuals with obesity and insulin resistance to individuals with normal weight and no insulin resistance to see if the ketone supplement affects groups differently.

This study will investigate the effect of tirzepatide on the reduction of morbidity and mortality in adults living with obesity and provide additional evidence for the potential clinical benefits of tirzepatide in this population.

This study is intended to investigate safety and feasibility of a new weight loss technique called endoscopic Gastric Mucosal Ablation (GMA) that does not require surgery, but can be achieved using an endoscopic procedure. Previous studies have suggested that weight loss after vertical sleeve gastrectomy (VSG) is partly due to the removal of normal stomach tissue suspected of having hormonal function. The study will investigate the minimally invasive treatment of obesity by means of argon plasma coagulation (APC) in combination with waterjet submucosal injection using HybridAPC. As primary objective total body weight loss (TBWL) will be determined as body weight difference at the 6 months follow up (FU) visit after the last treatment session in comparison to the body weight prior to the initial treatment. After signing the informed consent the doctor and research team will determine if the participant meets all requirements for this study. If a participant is confirmed to be a suitable candidate additional tests will be performed prior to the first application of GMA to assess the health status of the participant prior to treatment. During the screening and baseline visit the medical history and the medications of the participant will be reviewed. After the treatments the participants will be followed for up to 12 months to assess the outcome of the GMA procedure.

in this study the investigators will test anew technique to mange patients with morbid obesity and GERD by doing sleeve gastrectomy plus cruroplasty and omental rape around the gastroesophageal junction
