Active clinical trials for "Overweight"

The objective of this study is to determine the acute effects of a dairy supplement compared to a soy supplement on oxidative and inflammatory stress in overweight and obese subjects in the absence of any changes in adiposity.

The increasing prevalence of childhood overweight has been found to be related to decreased levels of physical activity (PA) and increased energy content of the diet. Childhood offers an opportunity to develop and support health-promoting behaviors. Pacific Kids DASH for Health (PacDASH) is a community-based intervention that links food, PA, and health, and targets overweight children in Hawaii with a goal of preventing further weight gain. Components of the intervention include a food and PA prescription delivered by physicians at community-based health centers complemented with a toolbox of activities, behaviorally tailored messages, and PacDASH educational materials. This project will extend and apply the nationally recommended DASH eating pattern to children and the growing population of Asians and Pacific Islanders. The investigators will incorporate culturally preferred foods, recipes, and PA messages that meet DASH and other national guidelines. The approach will target child food behaviors and social and environmental cues that are important to making healthy food and PA choices and will provide steps to behavior change. Farmers markets at participating health centers are a support resource for activities. Providing access to, coupons for, and guidance about selecting and preparing fresh fruits and vegetables at a convenient health center farmers market will support increased intake of nutrient-rich foods among these children who are overweight and at risk for obesity. Pacific Islanders are among the world's most obese populations while Asians, although of relatively low body mass index (BMI), carry much of their body fat in the upper body and exhibit greater health risk at the same BMI. Through this project, the investigators hope to learn more about body size and composition in children of the Pacific Region for whom there are few national data. In addition, evaluate the effectiveness of a community-based intervention within a health care system on managing overweight in children.

Randomized controlled single-blinded intervention study in 111 overweight and obese subjects with risk factors of developing type 2 diabetes, with the aim to investigate effects of isoenergetic high cereal fiber as compared with high protein diets over 6 and 18 weeks. Proof of principle study with analysis according to study protocol, investigating whether isoenergetic high cereal fiber and high protein diets with comparable fat contents, if adhered to and after exclusion of known confounders such as changes in body weight, intake of drugs with known effects on insulin sensitivity, or relevant changes in physical activity, indeed affect insulin sensitivity.

Overweight increases the risk to develop chronic diseases including type-2 diabetes and cardiovascular disease. The low-grade inflammatory status often seen in overweight subjects is thought to play an important role in disease development. The purpose of this study is to determine the role of inflammation on glucose metabolism and insulin resistance. In this study the effect of the anti-inflammatory treatment diclofenac on markers of inflammation and on parameters of glucose metabolism will be studied.

This clinical trial aims to compare the effect of a nutritional intervention based on Mindful Eating, with standard dietary treatment, in changing the eating behavior of overweight individuals.

Scientific evidence is growing on the health benefits of herbs/spices. The study is interested in understanding how various herb and spice blends influence the function of blood vessels. The study is also interested in how blood sugar, the insulin hormone and immune cells may be related to how well the blood vessels function. Herbs and spices have components called phytochemicals that may be related to how well blood vessels function. The study is planned to investigate these relationships. After qualifying to participate in the research study, participants will be asked to come to the Clinical Nutrition Research Center (CNRC) for four on-site Study Days, each lasting for about 8 hours with a 40 min followup to measure vessels' function the next morning. On each Study Day, different amounts of herbs/spices will be included in a breakfast meal. The herbs and spices are purchased in the grocery store and are Italian herbs, cinnamon, and a mix of pumpkin pie spices (cinnamon, ginger, clove, nutmeg). All meals will be prepared in the CNRC's kitchen using foods and ingredients purchased at the local grocery store. Blood collection and blood vessel function tests will be performed during the Study Day using typical procedures used in hospitals, doctor offices, and clinics.

The primary purpose of this study is to determine the effectiveness of six weeks of watermelon puree supplementation, compared to control (no treatment), on blood antioxidant capacity, inflammation markers in the blood, biomarkers of metabolism in the blood, and cardiovascular disease markers in the blood, and biomarkers in the blood related to watermelon ingestion in overweight post-menopausal women. The secondary purpose is to compare body composition and body mass between the watermelon supplement group and the control group.

The present study aims to investigate the effect of a standardized liquid breakfast containing a food grade propionate colon release form on ad libitum eating and appetite perception in healthy overweight humans using a double-blinded, randomized, cross-over study design

The main purpose of this study is to evaluate the safety and tolerability of LY3457263 when administered in combination with tirzepatitide in overweight or obese participants. The study will also evaluate how much of LY3457263 gets into the blood stream and how long it takes the body to remove it in overweight or obese participants. The study will last up to approximately 11 weeks.

Moderate hypercholesterolemia, metabolic alterations derived from overweight or obesity, and consequently and their related cardiovascular risks can be reduced through changes in lifestyle. A growing body of evidence shows a relationship between hypercholesterolemia and dysfunction of the gut microbiota. Gut microbiota is considered a keystone in maintaining the health condition of the host through multiple mechanisms affecting different metabolic processes, including lipid metabolism and cholesterol-related pathways. Bile acids (BA) are cholesterol-derived compounds synthesized in the liver and metabolized upon modification by gut bacteria once they reach the colon. Conversely, BAs shape the composition and function of the intestinal microbiota. This mutual interplay between BAs and gut microbiota regulates many physiological processes, including the lipid, carbohydrate and energy metabolism of the host. Previous studies based on Lactobacillus plantarum have shown 3 strains CECT 7527, 7528, and 7529 with the ability to adhere to the intestinal mucosa with very low toxicity, what makes them susceptible to be used as a probiotic. The lipid-lowering effect of the 3 bacteria strains was already evidenced in previous preclinical studies in animal models and clinical studies in hypercholesterolemic subjects. Up to now, however, little is known about the effects of the 3- combined Lactobacillus plantarum strains on levels and profile of bile acids in healthy overweight subjects, otherwise at low cardiovascular risk. The aim of this study is to explore on the mechanism of action of a Lactobacillus plantarum mixture (CECT 7527, CECT 7528 and CECT 7529) and evaluate the effect of this probiotic formulation on BA profile as well as on plasma lipids and other related biomarkers when administered in a dose-dependent regime in a cohort of overweight subjects. The probiotic product was administrated for 4 weeks with a weekly dose-regime of 2x, 3x, and 4x, respectively, in the second, third, and fourth week in relation to the first week. The effects were evaluated on: (1) level and profile of bile acids in plasma and feces, (2) plasma lipid/lipoprotein and fatty acid profile and (3) endocrine hormones, glucose metabolism and inflammatory markers in plasma.
