Active clinical trials for "Weight Loss"

The purpose of this study is to determine the effect of meal size and texture on the levels of incretin hormone, GLP-1, after Gastric Bypass Surgery (GBP). Patterns of food intake change after bariatric surgery and patients often eat multiple small low-calorie meals, a pattern that may affect blood glucose as well as incretin levels. Whether the release of GLP-1 after an oral challenge or a single liquid meal has any physiological relevance in 'real life' setting of multiple small meals diet is unclear.

This research study is being done to determine whether taking a dietary supplement called capsinoids, derived from sweet peppers, can activate brown fat that is already present or even generate new brown fat in individuals with excess weight. Previous studies have suggested that chronic consumption of capsinoids may be able to generate new brown fat in thin individuals. Capsinoids may also have a small positive effect on metabolism (increased calorie-burning) and fat loss. The knowledge gained in this study may eventually lead to more treatment options for people with excess weight.

The purpose of this study is to determine the effects of diet type selection based on response to a Carbohydrate Intolerance Questionnaire (CIQ) and genetic screening on success to a weight loss and exercise program.

Recent evidence shows that dietary supplementation with resistant starch (RS) increases fat catabolism and resting energy expenditure and decreases plasma insulin and glucose responses as well as the gut-derived hormone, glucose-dependent insulinotropic polypeptide (GIP). Consumption of whey protein has also been shown to increase energy expenditure and favorably affect gut hormones. Thus, investigators tested consumption of both RS and whey protein on energy expenditure and gut hormones in lean and obese women and men.

This is a randomized intervention study to examine the effects of the Moving Forward Guided Weigh Loss Intervention compared to a self-guided weight loss program on BMI and behavioral, biological, and psychosocial outcomes in overweight and obese African American women diagnosed with Stage I, II, or III breast cancer.

the investigators first aim is to determine the effect of low intensity exercise (without weight loss) on insulin sensitivity, muscle lipid metabolism, and factors regulating these processes in skeletal muscle after 1 day, 2 wks, 12 wks of training, and again after 3 days without exercise in obese adults. the investigators second aim is to determine the effect of combining low intensity exercise training with 10% weight loss on insulin sensitivity, muscle lipid metabolism, and factors regulating these processes in skeletal muscle. Although a single 40 minute session of exercise at a low exercise intensity will not improve insulin sensitivity, the investigators anticipate adaptations after two weeks of exercise training (6 session/wk; 12 session total) will improve insulin sensitivity and be accompanied by a reduction in fatty acid intermediates and a reduction in markers for pro-inflammatory activation in muscle. the investigators anticipate changes in insulin sensitivity, fatty acid partitioning, and pro-inflammatory markers the day after the last session of a 12 wk training program (without weight-loss) will be similar to that measured after 2 weeks of training. the investigators anticipate insulin sensitivity, accumulation of fatty acid intermediates, and pro-inflammatory activation will be markedly improved after 10% weight loss when measured the day after exercise. the investigators would expect the improvements in Insulin sensitivity, accumulation of fatty acid intermediates, and markers of inflammatory stress will be significantly attenuated when measured 3 days after the most recent exercise session, but beneficial effects of 10% weight loss on these metabolic endpoints will persist when compared with before weight loss.

The goal of this exploratory pilot study was to develop and test the acceptability and feasibility of an innovative alternative high school-based intervention to prevent further weight gain and/or promote weight loss among a sample of ethnically and economically diverse adolescents.

The purpose of the study is to examine how a naturally occurring fat found in meats, such as beef and lamb and milk, called conjugated linoleic acid (CLA), will affect your body weight and body fat content, blood fat levels, as well as selected safety parameters. The CLA will be supplemented in an oil form and will be added to solid foods as provided by the metabolic kitchen at the Richardson Centre for Functional Foods and Nutraceuticals (RCFFN).

The goal of the study is to investigate the efficacy of an evidence-based weight loss intervention, on a background of quality health care, on asthma control among obese adults. The intervention will employ a combination of recommended dietary and physical activity changes, and behavioral modification techniques.

The broad aim is to determine efficacy of a weight loss diet higher in protein and lower in carbohydrate combined with low intensity exercise to favorably impact body composition, bone health, physical function, metabolic disease and quality of life compared to a conventional higher carbohydrate diet in overweight women over age 60.
