Filter by:In this trial, the aim is to assess the clinical benefits and harms, as well as cost-effectiveness of an intensive weight loss (IWL) intervention that includes total dietary replacements, behavioural support and weight-loss medication compared with existing weight management programmes within primary care for people with obesity class I or uncomplicated obesity class II or higher.
Calorie restriction (CR) is the most important treatment for weighting loss. In recent years, two novel types of intermittent fasting recently have gained more attention: the 5:2 diet and time-restricted eating (TRE). TRE requires individuals to eat in a specified number of hours per day (typically 4 to 10 hours) without energy intake restriction. The 5:2 diet involves 5 feast days and 2 fast days per week; participants eat ad libitum without restriction on feast days while 25% of energy needs (approximately 500-800 kcal per day) are consumed on fast days. However, the effects of dietary strategy of intermittent fasting plus time-restricted eating (modified time-restricted eating: TRE 5 days and fasting 2days per week) on weight loss and cardiometabolic risk factors in obese adults have not been proved. This randomized controlled trial aimed to evaluate the effect of modified time-restricted eating (mTRE) and CR on weight loss and cardiometabolic risk factors in obese adults compared to usual health care over 12 months.
The Investigators propose suture plication placement at the distal gastric body drives a significant portion of weight loss in endoscopic sleeve and sutures only need to be placed in the distal gastric body. Therefore, in this pilot study, the investigators aim to compare "belt" with "belt and suspenders" plication pattern using the Endomina system to determine percent total weight loss.
Obesity and cardiometabolic risks are significant public health issues, with about two-thirds of U.S. adults overweight or obese. Weight loss can prevent these health problems, but current lifestyle interventions have limited success. New, effective strategies are needed to address this rising issue at the population level. The goal of this clinical trial is to investigate how a behavioral intervention combined with technology impacts weight loss in young adults. The main questions it aims to answer are: - How does the combination of behavioral intervention and technology influence weight loss in young adults? - How does the combination of behavioral intervention and technology influence energy intake in young adults?
This trial is conducted in China. The purpose of the 24-week trial is to investigate the efficacy of henagliflozin to induce body weight loss and the purpose of the extension is to evaluate the hypoglycemic effect of henagliflozin in obese subjects without diabetes. Trial has the following two periods: 1) A 12-week randomized, double-blind, placebo-controlled, multi-center trial for evaluating the efficacy of henagliflozin to induce body weight loss; 2) A 12-week multicenter randomized controlled open-label trial for evaluating the hypoglycemic effect of henagliflozin followed by a 24-week extension period.
Metabolic-dysfunction associated steatotic liver disease, often referred to as "fatty liver disease", is a leading cause of liver failure. Dietary weight loss is a cornerstone of treating fatty liver disease, but access to traditional in-person nutritional education is often limited by cost, availability, and transportation. Immersive virtual reality (iVR) has the potential to not only overcome these barriers, but also provide an interactive learning experience, such as measuring and preparing foods. Therefore, the investigators have created and validated an iVR dietician program known as the Immersive Virtual Alimentation and Nutrition (IVAN) using evidence-informed practices from the Academy of Nutrition and Dietetics. The goal of this project is to translate the IVAN program from human and patient research to practice and community research. The investigators plan to accomplish this by performing a randomized clinical trial evaluating the effect of the IVAN program in combination with synchronous audio/video dietary counseling on self-reported dietary intake and weight compared to in-person counseling. Concurrently, the investigators will provide a survey assessing implementation outcomes to both groups as well as the dietician at each study visit, and crossover the intervention at study completion so all participants assess the IVAN program. Additionally, the investigators will have clinic health care providers experience the IVAN program and assess implementation outcomes.
This study aims to conduct a feasibility trial to examine the feasibility and acceptability of conducting a randomized controlled trial that evaluates the effect of the weight management intervention on anthropometric measures (body weight and BMI), dietary quality, physical activity levels, physical and psychosocial functioning, self- efficacy for weight loss and quality of life.
The incidence of childhood obesity is increasing, followed by metabolic diseases related to overweight and obesity in children. High intensity interval training (HIIT) has recently been shown to improve the body composition and cardiovascular health of obese children. Currently, there is little evidence on the impact of exercise intensity on endocrine and metabolic indicators and quality of life in obese children. The main purpose of this study is to compare the effects of short-term supervised high-intensity interval training and moderate intensity continuous training (MICT) on metabolic indicators in obese children under an energy limited balanced diet. A multicenter prospective randomized controlled trial was conducted on 388 obese children in South China. The experimental group will be randomly assigned to (1) HIIT and energy limited balanced diet, and (2) MICT and energy limited balanced diet. The experimental group will participate in a 3-month (supervised) exercise training. The measurement of the study endpoint will be followed up at baseline, 3 months (after supervised intervention), 9 months, and 1 year. The primary endpoint is the percentage of weight loss (△ Wt%). Secondary endpoints include waist to height ratio, body mass index (BMI), body fat percentage, insulin resistance index (HOMA-IR), insulin secretion index (ISI), and Δ HtSDSBA. The results of this study will generate a wealth of information on the impact of exercise intensity on weight loss and endocrine metabolism in obese children, and develop more effective evidence-based exercise prescription guidelines in this population.
Quantify the effect of an innovative weight loss management on rhythm control.
Class 4 obesity is defined as a BMI ≥50Kg/m2, representing approximately ≥150 pounds of excess weight. For patients with Class 4 obesity, metabolic and bariatric surgery (MBS) is the only effective treatment. However, MBS is associated with a higher rate of perioperative morbidity and mortality for patients with Class 4 obesity. Additionally, more patients with Class 4 obesity experience suboptimal weight loss. For patients with Class 4 obesity, preoperative weight loss can reduce the technical difficulty of surgical procedures, rendering MBS safer. Preoperative weight loss may also decrease visceral adipose tissue and liver volume as well as reduce weight-related comorbidities. A very low-calorie diet (VLCD), which involves restricting caloric intake to approximately 800 kcal/day, is one strategy to help patients achieve weight loss preoperatively. Although studies show that a VLCD prior to MBS yields weight loss, reduces liver volume and rates of perioperative complications, most preoperative VLCDs are short (2-8 weeks) with variable adherence. To date, no study has systematically assessed the feasibility and acceptability of a standard 12-week VLCD among patients with BMI ≥50 pursuing MBS. No study has evaluated postoperative weight loss among patients who have undergone a preoperative VLCD. This study will be a single arm trial designed to test the feasibility, acceptability, and preliminary efficacy of a 12-week VLCD program prior to sleeve gastrectomy (SG) and associated weight loss up to 1 year following MBS. The investigators will enroll 24 patients aged 18-70, with a BMI≥50Kg/m2, and are approved for SG. Participants will consume up to 5 meal replacement protein shakes and 2 cups of vegetables daily for 12 weeks. Participants will attend weekly in-person office visits with the clinicians at the Hartford Hospital Medical and Surgical Weight Loss Center in Glastonbury, CT to assess weight loss, physical and mental health, feasibility and acceptability of and adherence to the VLCD. The investigators hypothesize that a 12-week VLCD is feasible in this population, defined as ≥70% (18 out of 24 participants) completing the program. The investigators hypothesize that better attendance at the weekly visits and higher adherence to the diet recommendations will provide greater weight loss preoperatively and percent total weight loss at the completion of VLCD, on the day of MBS, and at 3, 6, and 12 months post-surgery. Findings from this study may lead to additional projects that aim to develop and implement an optimal pre-surgery and post-surgery clinical care model for bariatric patients.
