Active clinical trials for "Overweight"

The purpose of this study is to determine the effect of the community-based obesity treatment (PP), compared to usual care (UC), on changes in maternal weight over 12 months.

This project will evaluate the daily intake of whole eggs in the Mediterranean Diet (Med Diet). Cholesterol levels are normally related to cardiovascular disease (CVD) risk. Dietary fat and the total diet makeup are well known modifiers of CVD risk. The Med Diet has been shown to decrease blood lipids (fats) and reduce inflammation. Cholesterol intake from eggs may not be as bad as once thought and, in fact, may help to improve the blood lipid (fat) levels. This study is being done to test how the addition of eggs to a Med Diet affects blood lipids and other risk markers for CVD.

This study investigates whether walnuts help to promote weight loss, associated with increased meal satiety and satisfaction, in 100 overweight and obese men and women who are participating in a 6-month behavioral weight loss intervention. Participants will be randomly assigned to a walnut-enriched reduced-calorie diet or a standard reduced-calorie diet. Body weight, risk factors for cardiovascular disease, and self-reported feelings relevant to satiety and appetite will be measured at baseline and 3- and 6-month follow-up. Also, the response of gastrointestinal tract hormones following meals with or without walnuts will be measured in a subset of study participants (n=20). Results from this study will contribute to understanding the role of nuts in weight control, including further knowledge of the mechanisms, and will expand knowledge of how nuts in the diet may contribute to the prevention and management of obesity.

Investigators from the University of California-Los Angeles (UCLA) and The Children's Clinic of Long Beach (TCC) are conducting a randomized, controlled comparative effectiveness trial of two government-sanctioned behavior change approaches to weight control with TCC's obese patients. The first approach is the calorie-counting calorie restriction (CC) approach used in the Diabetes Prevention Program. The second approach is the high-satiation/high-satiety approach represented by MyPlate.gov. The MyPlate nutritional goal is to double patient fruit and vegetable intake, legume intake, and whole grain intake. Both conditions stipulate 150 minutes of moderate physical activity a week. Study participants will be 300 of TCC's obese patients, 76% of whom are expected to be Latino, 13% African American and 11% Other Ethnicities. The interventions will be implemented by trained community lifestyle change coaches with brief support from clinicians. The interventions will include two home visits, two group education sessions and seven telephone behavior change coaching sessions. Compared to the CC approach, the MyPlate approach is hypothesized to yield better 12 months patient-centered outcomes, particularly self-reported satiety.

Infertility has been currently recognized as a disorder related to obesity. Among several metabolic changes associated with obesity, insulin resistance appears to be linked to hormonal disorders that affect reproductive system. Leptin and ghrelin are hormones involved in energy balance regulation and are also associated with reproductive system regulation, but its relationship with infertility is scarce. The aim of this study is to determine the effect of a hypocaloric diet with different glycemic indexes on ghrelin and leptin levels, hormonal, metabolic and reproductive parameters in infertile overweight or obese women candidates to in vitro fertilization. The patients who meet the inclusion criteria and accept to participate in the study, will be allocated in one of the following groups: Hypocaloric Low Glycemic Index diet group; Hypocaloric Conventional diet group or Control group (maintenance of usual diet) and follow the study protocol for 12 week. Immediately after the end of the diet protocol, the patients will be submitted to the in vitro fertilization treatment.

The purpose of this study is to determine the effect of a spousal support enhanced weight loss program on weight loss among African American men.

The investigators aimed to study the effect of supplementation with species of Lactobacillus on anthropometric measurements, body composition, appetite and serum lipid profile in overweight and obese adults

A Phase 2 study with two cohorts of differing doses designed to evaluate the efficacy, safety and pharmacokinetics (PK) of MEDI0382 in patients with Type 2 Diabetes Mellitus (T2DM). Approximately 63 subjects will be enrolled across two cohorts.

The purpose of this study is to examine the acceptability and efficacy of a modified Weight Watchers program over 24 weeks. Assessments will be conducted at 0, 3, and 6 months.

Time-restricted feeding (TRF) is a novel type of intermittent fasting that involves eating within a daily period of 10 hours or less, followed by fasting for at least 14 hours daily. Several studies in rodents report that TRF reduces body weight, improves blood sugar control, and reduces the risk of cardiovascular disease-even when food intake is matched to the control group or no weight loss occurs. Preliminary evidence suggests that TRF may also increase weight loss, fat loss, and reduce the risk of diabetes and cardiovascular disease in humans. This study will test whether TRF enhances fat loss and increases weight loss in adults with obesity, relative to conventional dieting alone. In addition, this study will determine whether TRF reduces risk factors for type 2 diabetes and cardiovascular disease and will measure the feasibility and acceptability of TRF. In conjunction with the parent study described above, four ancillary studies will be conducted: Effect of weight loss on nitrogen metabolism and bacteria in the mouth. The primary endpoints for this ancillary study are plasma and salivary nitrate and nitrite, and the secondary endpoints are salivary nitrate reductase activity and salivary bacterial abundance. Effect of weight loss on several biomarkers related to kidney stones. The primary endpoint for this ancillary study is urinary oxalate, and the secondary endpoints are urinary citrate, chloride, sodium, potassium, calcium, phosphorus, uric acid, and creatinine. Effect of meal timing on blood pressure regulation and kidney function. The primary endpoints of this ancillary study include urinary aldosterone excretion, sodium, potassium, and endothelin, whereas the secondary endpoints include nitric oxide and albumin. Additional exploratory endpoints include renal injury markers (KIM-1, nephrin, and urine albumin-to-creatinine ratio), measures of reactive oxidative stress (e.g., hydrogen peroxide and TBARs), and urinary exosomes. Urine will be analyzed in 12-hour bins to determine how meal timing affects differentially affects these endpoints during the daytime and nighttime. The effects of weight loss on these endpoints may also be considered. Validation of a meal timing questionnaire to assess the distribution of food intake throughout the day.
