Obesity Clinical Trials

Effective nutrition strategies for combatting and/or preventing obesity still need to be identified. This has been the case despite the numerous and different approaches that have been taken. Potential targets for combatting/preventing obesity have been identified, but long-term solutions have not emerged. This study uses time restricted feeding to study the role of dietary protein in obesity prevention and/or treatment. The objectives are to determine the role of skeletal muscle mass as a driver of energy-sensing mechanisms and peripheral signals that regulate appetite and energy intake in overweight and obese adults and to determine the effects of protein timing on muscle mass to regulate appetite and energy intake in overweight and obese adults.

Obesity is associated with increased cardiometabolic disease risk due, in part, to heightened chronic inflammation arising from adipose tissue. There are no current targeted therapies to prevent or reverse the chronic inflammation of obesity, and a better understanding of these inflammatory pathways in humans is key to future therapeutic interventions. This trial will determine both the anti-inflammatory potential of the SGLT2 inhibitor empagliflozin, and the contribution of adipose inflammation to surrogate measures of cardiovascular disease in a randomized controlled trial of obese patients.

The objective of this study is to better define the role of the hormone angiotensin-(1-7) in energy balance. We will test the overall hypothesis that angiotensin-(1-7) increases resting energy expenditure and promotes markers of heat production (thermogenesis) in white adipose tissue in human obesity.

This Proof-of-Concept study consists of a series of uncontrolled pilot studies to refine a behavioral weight loss trial using a "small change" approach for emerging adult college students with overweight/obesity. The primary aim of this study is maximize student acceptability of the intervention and weight loss outcomes. Read Less

The purpose of this study is to conduct a 6-month pilot randomized trial to determine the feasibility and acceptability of theory-based mobile weight loss interventions for survivors of adolescent and young adult cancer (AYAs). The interventions use a mobile smartphone application, previously developed for individuals at risk for type 2 diabetes and adapted for AYAs, that integrates weight and physical activity from digital devices with simplified dietary monitoring in a behavioral weight loss program.

Beans are a forgotten staple food that shows promise in improving health. The goal of this study is to look at how bean supplementation affects metabolic and bowel health. In the long-term, the investigators believe this research will lead to a better understanding of the impact of beans on bowel health. The investigators also hope that this research study will help us understand ways to improve human diet and prevent colon cancer in the future. Read Less

This study, at the Western Human Nutrition Research Center (WHNRC), will focus on whether or not achieving and maintaining a healthy body weight is the most important health promoting recommendation of the Dietary Guidelines for Americans (DGA).The investigators hypothesize that improvement in cardiometabolic risk factors resulting from eating a DGA style diet will be greater in people whose energy intake is restricted to result in weight loss compared to those who maintain their weight. The investigators further propose that during a state of energy restriction, a higher nutrient quality diet such as the DGA style diet pattern, will result in greater improvement in cardiometabolic risk factors compared to a typical American diet (TAD) pattern that tends to be lower nutrient quality (more energy-dense and less nutrient-rich.)

The purpose of this study is to conduct a micro-randomized trial to learn which evidence-based targets within a mobile intervention for binge eating and weight-related behaviors are most impactful for which people and in what sequence. Read Less

African American adults sleep less and obtain worse quality sleep compared to the national average, and emerging evidence links inadequate sleep with greater morbidity and mortality from chronic diseases such as diabetes, obesity, and cancer. To address this public health concern, the proposed research seeks to use a multi-method approach to adapt a sleep intervention for African American adults with overweight/obesity not meeting national sleep duration or physical activity recommendations. The overall goal of the project is to reduce cancer and obesity-related health disparities among African Americans. Read Less

Obesity and related metabolic comorbidities have been associated with more than a 4-fold increased risk of incident cognitive impairment, including Alzheimer's disease and related dementias (ADRD). Dysfunctional metabolic flexibility is increasingly recognized as a critical mechanism linking metabolic risk factors to risk of cognitive impairment, although few studies portable behavioral strategies to enhance metabolic function among individuals at risk for ADRD. The present study will examine the feasibility and acceptability of a 12-week time restricted feeding intervention among individuals with mild cognitive impairment (MCI). Changes in cognitive and metabolic function will also be examined. Read Less

The major objective of this project is to examine whether daily consumption of milk polar lipids (MPLs) influences cardiometabolic risk factors. Read Less

This trial studies the safety and how well negative pressure wound therapy works in healing the abdominal incision in obese patients undergoing free flap breast reconstruction surgery. Using negative pressure wound therapy (NPWT) instead of standard dressing (bandages) may improve wound healing at the surgical site in the abdomen where tissue was collected for breast reconstruction surgery.
