Active clinical trials for "Weight Loss"

Obesity has become a global epidemic with huge public health implications. Although clinical significant weight loss (WL) can be achieved by a combination of diet and behavioral modification, strong metabolic adaptations, with increased appetite and suppressed energy expenditure, are activated, which compromise WL maintenance and increase the risk of relapse. The aim of this project is to investigate the potential role of WL rate in modulating such responses. More specifically, the investigators want to determine if a similar WL achieved rapidly vs slowly induce the same compensatory responses to weight reduction. A secondary aim is to assess if speed of weight loss can influence motivation. A large battery of assessments will be performed before and after weight reduction including body composition, resting metabolic rate, substrate oxidation, exercise efficiency, fasting and postprandial release of several appetite-regulating hormones, subjective feelings of hunger and fullness and motivation. This project can bring large practical benefits concerning the design of weight loss programs to minimize weight relapse.

The purpose of this study is to find out if there is any change in diet on food cravings and weight loss in the 12 months following bariatric surgery.

The purpose of this study is to evaluate the role of different parenting skills and parenting styles in the success of children enrolled in a family-based behavioral weight control program and to compare these skills and styles to those used by families with normal weight children.

The purpose of this protocol is to determine how band fill volumes that are based on intraband pressure readings can influence the comfortability of the band and to compare weight loss with this methodology to weight loss with the conventional approach recommended in existing product labeling.

This trial will assess the feasibility of reduction gastroplasty with standard suture in bariatric patients who are candidates for surgical weight loss intervention.

Subjects having a gastric band fitted will have the first band adjustment done at surgery. The stoma will be set to 7mm using the EndoFLIP system to measure stoma size. Thereafter, band adjustments will be made using an adjustment chart, created at surgery, which shows stoma size versus band fill, to make adjustments in the normal follow-up visits. It is hypothesized that an early adjustment at surgery will promote earlier weight loss, and result in fewer band adjustments being required in the first year after surgery.

The prevalence of severely obese children is on the rise. Behavioral therapies for weight loss are successful in some, but others need more aggressive approaches such as drug therapy. In addition, up to 25% of severely obese children have impaired glucose tolerance (IGT), which places them at significantly elevated risk of developing type 2 diabetes mellitus and cardiovascular disease. Although various drug therapies for weight loss and IGT have been explored in adults, few have been evaluated in children. Recently, a new drug class has emerged that targets deficiencies of GLP-1. One of the main glycemic mechanisms of action of the GLP-1 agonists such as exenatide is to enhance glucose disposal in the postprandial setting and improve glucose tolerance. In addition, exenatide can induce weight loss by decreasing appetite and slowing gastric motility.

Sixty percent of patients with difficult to control asthma seen in our outpatient clinic are obese. The impact of weight reduction in this subpopulation of asthmatics has not been studied. Our aim is to evaluate the impact of weight reduction on asthma control of these patients.

The purpose of this study is to determine if dietary consumption of Revival Soy can improve the appearance of the skin, hair, and finger nails and support weight loss in overweight, premenopausal women.

The purpose of this study is to pilot test a program to help overweight and obese individuals with a lower extremity amputation (LEA) lose weight and become more physically active. The investigators will randomize approximately 30 individuals to either a self-directed weight loss program (n=15) or a coached weight loss program (n=15). The primary purpose of this pilot study is to determine if a home-based weight loss/physical activity (PA) intervention is feasible in individuals with a LEA. MOVE-LEAP is a 20-week program that involves 11 phone calls from a health coach and a single home visit by a physical therapist. This pilot study aims to: test the feasibility of recruiting overweight/obese individuals with LEA into a randomized trial; assess whether the intervention can be delivered with high fidelity, and evaluate whether the intervention is acceptable to and safe as determined by participant feedback, participation and retention for outcome measures.
