Active clinical trials for "Overweight"

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.

The main purpose of this study is to evaluate the safety and tolerability of LY3502970 in healthy overweight and obese participants. The blood tests will be conducted to measure how much LY3502970 is in the bloodstream and how the body handles and eliminates LY3502970 in these participants. The study will last up to 42 days excluding the screening period.

The study will investigate the safety, feasibility, and efficacy of beta-alanine supplementation in adults with overweight or obesity. Beta-alanine is a widely used dietary supplement that can increase the amount of carnosine in skeletal muscle. Both carnosine and beta-alanine occur naturally in animal food products and previous research shows that supplementation with beta-alanine leads to an improvement in exercise performance; more recently, the present investigators have shown that increasing carnosine can also help to improve cardiometabolic health, detoxify skeletal muscle, and improve glucose (sugar) uptake into muscle cells. The investigators will recruit 30 participants (15 per arm) with overweight or obesity who meet the study criteria (this accounts for up to 20% attrition - a minimum of 12 participants per arm). Those who are eligible will be required to receive three short telephone calls and attend three laboratory sessions. Participants will be randomised to receive either beta-alanine or placebo (an inactive sugar pill) for the 3-month study period. To see whether beta-alanine supplementation is feasible in this population the investigators will measure recruitment, adherence (how well people can stick to the supplement regime), the number and nature of side effects, and blinding to the intervention. Markers of cardiac function, glycaemic control, and metabolic health will also be explored. All measurements will take place before and after a 3-month supplementation period. This will provide us with novel information of the role of beta-alanine and carnosine in cardiometabolic health; and will aid in the planning of a larger randomised controlled trial to assess the efficacy of beta-alanine supplementation as a therapeutic strategy.

This study evaluates the effects of physical exercise through active videogame in the microcirculation, macrocirculation, cardiorespiratory function and physical fitness in overweight adolescents. For that, they will be randomized into two groups, one being a control group and the other intervention group. The randomization will be made by school. The intervention group will perform the physical exercise through the active video game, three times a week, for 50 minutes, during 8 weeks. Reassessments will be performed before and after the intervention to evaluate the outcome variables.

The primary purpose of this study is to examine the effects of chronic exercise training and an acute session of exercise on key risk factors associated with Metabolic Syndrome (e.g., glucose tolerance, blood lipid profile, and blood pressure) and alterations in subcutaneous adipose tissue structure and metabolic function in overweight adults.

Consuming whey protein may have beneficial effects on health, principally by having an impact on blood glucose metabolism, but also by affecting appetite. The purpose of this project is to investigate the effect of consuming whey protein preload prior to breakfast, following a bout of low/moderate intensity exercise (brisk walking), on glucose and lipids in the blood as well as on appetite. It is hypothesised that the consumption of whey protein before a meal after prior low/moderate intensity exercise may positively affect postprandial handling as well as appetite sensations and consequently reduce intake at a subsequent meal.

The present study is designed to examine the effect of changes in body weight and related parameters associated with a commercially-available, low-carbohydrate diet plan. A parameter proposed to be studied here is the impact of fructose restriction and weight loss on serum uric acid concentrations and arterial stiffness.

Using technology alongside a pediatric chronic disease specialist and behavior specialist, the investigators are planning to help care for and coordinate the healthcare of children with chronic diseases, particularly childhood obesity, diabetes and asthma in Miami's most vulnerable communities. The University of (UM) Miller School of Medicine (MSOM) Pediatrics and TeleHealth departments propose to leverage information and communications technologies (ICT) in an innovative approach to improve the quality, access and efficiency of pediatric services for children and their families.

The purpose of this study is to determine the effect of Gelesis100 on the absorption of metformin both with and without a meal.

Previous research shows that a diet high in fat has harmful effects on gut health. This increases the chance of developing obesity-related diseases (such as type 2 diabetes) and disrupts cognition and mood. Research has suggested that gut health can be improved by taking certain supplements, including resveratrol (a polyphenol found primarily in red grape skins). Resveratrol has also been shown to improve brain blood flow and possibly brain function - however, there is limited research studying this. This study will investigate the effects of 12 weeks daily consumption of resveratrol on cognitive function, cerebral blood flow, gut microbiota and systemic inflammation in overweight and obese healthy adults.
