Weight Loss Clinical Trials

The purpose of this study is to find out what combination of components, if any, offers the best support for keeping weight off after someone loses weight. Long term weight loss maintenance is a challenge for many people who lose weight. There are many strategies, or components, people may use to avoid regain, but investigators do not know if there is a best, or optimal, combination of such components that can be done without adding a lot of cost or other burdens for people. * The primary goal of this clinical trial is to identify the optimal package that maximizes weight loss maintenance. * The study also wants to understand the reasons why these components may work and if certain components help specific sub-groups of people. Participants will engage in a 16-week Phase 1 Weight Loss Program. Participants who lose 5% or more of their weight during that program will continue to Phase 2 Extended Care and be randomly assigned to 0, 1, 2, 3, or all of four methods of weight loss maintenance. They will use their assigned package for 12 months. Researchers will compare 16 different possible combinations of components and learn which of the 16 packages offers the best support for keeping weight off. The four components participants could be assigned to in Phase 2 are: 1. Reduced Food Variety: Limiting the variety of foods participants eat by having them choose a few high-calorie, low nutrient foods to eat regularly 2. Home-based Resistance Training: Engaging in exercises that build strength from the comfort of the participant's own home 3. Buddy Training and Support: Having a friend or "buddy" get trained to support the participant 4. Acceptance and Commitment (ACT) Workshops: Having participants learn skills to handle tough thoughts and feelings about weight control in a healthy way Participants will have their weight measured and complete surveys 4 times if they complete both Phase 1 and Phase 2. During Phase 1, participants will attend weekly group sessions and be in touch with a study staff member investigators call a Wellness Coach. During Phase 2, participants will stay in touch with their Wellness Coach, use their assigned package, and answer questions about their experience periodically. Read Less

The purpose of this registry study is to collect data through medical chart review and in patient visits on the efficacy and safety of various Endoscopic Bariatric therapies (EBTs). This is a retrospective and prospective, observational, medical chart review study for at least 6 standard of care visits up to 1 years after a subject consents for study participation. Read Less

The aging population is rapidly increasing, and it is important to identify dietary factors that can prevent disease and promote health in this group. Legumes, such as peanuts, are a plant-based food high in protein and unsaturated fat making this a healthy choice but are not consumed frequently enough in older adults. Studies have shown that regular nut consumption is associated with lower adiposity and reduced weight gain, and several dietary pattern studies indicate that nuts and legumes are associated with better bone health. In addition, our preliminary translational data indicates that a higher monounsaturated fatty acid (MUFA) intake is associated with improved bone mineral density (BMD) and quality. Given these findings, the proposed study aims to examine the impact of consuming peanut products on bone health, metabolic health (e.g., serum glucose, insulin, lipids and inflammation), markers of brain and sleep health, and physical function in overweight and obese older adults before and after a six-month weight loss intervention using a randomized controlled design. The results of this study have the potential to provide valuable insights into the role of peanuts as a sources of fatty acids in promoting health and preventing disease in at-risk adults. Read Less

The purpose of this research is to determine the effectiveness of a coordinated program (Dyad Plus) that would help to facilitate self-monitoring, positive communication, joint problem solving, and social support to increase physical activity, healthy eating, and weight loss. Participants of the Brenner FIT (Families In Training) pediatric weight management program and their parent/guardian will co-enroll in weight loss programs. Parents/guardians will receive the components of By Design Essentials. Read Less

The goal of this clinical trial is to learn the best combination of family components that yields optimal weight loss among Black adults. The main question it aims to answer is: What combination of four family components in combination with a standard behavioral weight loss program yields optimal weight loss among Black adults? Researchers will compare different combinations of family skills components (communication content, cohesion content, number of sessions, and mode of delivery) to see the best weight loss. Participants will: * Participate in a 6-month behavioral weight loss intervention * Attend core weight loss in-person group sessions, and dyad based family sessions * Keep track of weight, dietary intake and physical activity Read Less

This is a phase 2, 13-week randomized, double-blind, placebo-controlled, parallel arm dose-finding study that will evaluate the safety, tolerability, weight loss efficacy, pharmacodynamic effects, and pharmacokinetics of VK2735 Oral Formulation in adults who are obese (BMI ≥30 kg/m2) or who are overweight (BMI ≥27 kg/m2) with at least one weight-related co-morbid condition. VK2735 or matched placebo will be administered once daily. Read Less

Changes in adipose tissue biology are now recognized as a key factor underlying the increased risk of metabolic and cardiovascular disease with obesity. Clinical interest in adipocyte-derived extracellular vesicles (Ad-EVs) has intensified due to their potential as circulating biomarkers of adipose tissue health and systemic messengers, regulators and mediators of cardiometabolic health and disease with obesity. The investigators hypothesize that elevated Ad-EVs in adults with obesity will be negatively associated with endothelium-dependent vasodilation. Furthermore, the investigators hypothesize that in adults with obesity, intentional weight loss-induced reduction in circulating Ad-EVs is associated with greater endothelium-dependent vasodilation.

The purpose of this study is to assess whether providing a parent-only group program before providing a parent and child group program works better than the parent and child group program alone. Read Less

The study aims to randomize 250 participants to 1 of 2 arms: a.) an Active Intervention Group (based on the Look AHEAD\* ILI) or b.) a Comparison Group (based on the Look AHEAD DSE Comparison group) to test the hypothesis that a multicomponent, multilevel behavioral weight loss intervention (Active Intervention Group) adapted for underserved groups and delivered through Health Information Technology (Health IT) tools via the Electronic Health Record (EHR) patient portal, will result in significantly greater weight loss 12 months after enrollment compared to the Comparison Group. \*The Look AHEAD study was a multi-center, randomized clinical trial involving overweight and obese persons with type 2 diabetes, aimed to determine the effects on the cardiovascular outcomes of an intensive lifestyle intervention (ILI) for weight loss, in comparison to the diabetes support and education intervention (DSE).

Pregnancy and delivery are major stressors on the female body and contribute significantly to permanent weight gain and associated morbidity in women. This can profoundly affect the ability of active duty (AD) women to advance in their career. The first 12 weeks postpartum are the time period during which the most significant weight loss occurs and is critical in achieving a healthy weight in the first year postpartum. Many factors contribute to effective weight loss in this period among which the most critical are diet, exercise, and sleep. Breast feeding and depression may also affect weight changes postpartum. Research has shown diet to likely be the most crucial of these factors. The PADaWL study is designed as a randomized controlled trial to assess the effects of dietary intervention on weight and physical fitness versus routine postpartum care in the first year postpartum. Subjects will be primiparous AD women from any military service recruited in the obstetric clinic in the third trimester of pregnancy at Tripler Army Medical Center. Data will collected in an ambi-directional fashion with pre-pregnancy physical fitness data, demographic and pregnancy data collected at time of enrollment. Subjects will be randomized to receive intensive virtual sessions with a dietician vs routine postpartum care for the first 12 months postpartum. We will utilize a biometric device to monitor activity levels and sleep, web-based diaries to monitor breast feeding and diet, and validated questionnaires to evaluate depression as well as diet and sleep. Subjects will be monitored weekly for the first 12 weeks postpartum and will then be further evaluated at 6, 9 and 12 months postpartum. Primary outcome is weight at 12weeks postpartum and whether subjects have achieved military standards. Secondary outcome will be weight at 12 months postpartum and whether subject has achieved weight and fitness standards. The study intends to collect large amounts of data, and we intend to analyze which factors may be contributing to weight retention postpartum. This study should provide an accurate assessment of the effects of pregnancy on AD women. It should generate a clean and accurate dataset on which multiple follow-on studies can be performed and provide data for designing further intervention studies in postpartum women. The results of this study should also be able to assist in developing policy and guidance concerning AD women and pregnancy. Read Less
