Active clinical trials for "Overweight"

Purpose: The investigators propose a 20-participant randomized 2-arm parallel trial with a delayed-intervention control examining how 8 weeks of moderate-intensity walking exercise alters the gut microbiome, short chain fatty acid (SCFA)-producing taxa, and the cardiometabolic profile and body weight of individuals who are overweight or obese and have prediabetes (PreD). Aim 1: Examine and compare exercise-related shifts in the gut microbiome of individuals with PreD. Aim 2: Examine and compare exercise-related changes in SCFA-producing taxa. Exploratory Aim: Examine what percentage of the exercise-related changes observed in participants' gut microbiome and SCFA-producing taxa mediate changes in their cardiometabolic profile and body weight.

The investigators aim to establish a protocol for metabolic rate measurements obtained using continuous monitoring of oxygen consumption and carbon dioxide production in a whole room calorimeter setting.

Children with an excess in body weight, increase the risk of obesity-related co-morbidities and cardiovascular diseases. Childhood obesity may be due to diets laden with fat and lack of physical activity. Omega-3 fish oil is a supplementation that may promote a greater reduction of pro-inflammatory mediators; combined with exercise and nutritional regimens it may also help improve glycemic, lipid markers, and body composition in overweight children and adolescents.

The purpose of this study is to compare the effects of an 8-week aerobic training program upon fat oxidation in vivo and markers of skeletal muscle mitochondrial content and oxidative capacity in sedentary obese subjects with and without type 2 diabetes. We will also investigate if mitochondrial content in muscle predicts success of weight loss. The specific aims are: To compare systemic fat oxidation rates; To measure mitochondrial content in muscle before and after aerobic training; To determine if decreased mitochondrial content is also associated with decreased mitochondrial oxidative capacity; To measure non-plasma fatty acid oxidation in vivo during submaximal exercise conditions both prior and after aerobic training; To determine whether increases in fat oxidation due to physical activity predict weight loss success when a reduced calorie diet is added to a physical activity program.

Our objective in this study is to identify the extent to which insulin drives the accumulation of lipids in skeletal muscle of humans. We will test the hypothesis that 4-hours of mild hyperinsulinemia will result in significant muscle lipid accumulation and that such effects will be similar in lean and overweight/obese humans.

This two-phase study aims to explore ways to predict who will respond well to the weight loss drug lorcaserin and to understand the mechanisms that develop which limit drug efficacy. Subjects will be recruited for a 5-week crossover study (phase 1) with lorcaserin and placebo followed by treatment with lorcaserin for 24 weeks (phase 2).

This randomized pilot clinical trial studies how well circuit, interval-based aerobic and resistance exercise works in targeting metabolic dysregulation in stage I-III breast or prostate cancer survivors. Circuit, interval-based aerobic and resistance exercise may help to improve cardiovascular fitness, weight loss, healthy lifestyle behaviors, and muscle strength in breast or prostate cancer survivors.

The aim of this study is to compare the effects of diets with different glycemic load (GL) on body composition and biochemical markers in overweight and obese subjects during a 12-month period.

This trial studies how well exercise and nutrition education work in improving physical function and quality of life in older breast cancer survivors. Exercise and nutrition education may help to improve the level of fitness, cardiovascular health, and quality of life in breast cancer survivors.

Oxyjun is known for improving cardiovascular endurance. Overweight and obese individuals are at increased risk of cardiovascular complications. To lower the risk, these individuals need to remain physically active with acceptable aerobic fitness. Hence, the objective of the study is to investigate the effect of Oxyjun on aerobic fitness in physically active overweight and obese individuals. All subjects in the study will be tested for maximum aerobic capacity , body composition, and serum biomarker for fitness.
