Filter by:The purpose of this study is to determine if a 24 week weight loss program with orlistat 60 mg will produce greater changes in body composition compared to placebo.
The purpose of this study is to improve and analyze the level of physical activity in immigrant women from the Middle East and Latin America living in Sweden. The investigators will also investigate if glucose, insulin, and lipid metabolism; stress-related hormone production; and subclinical inflammatory activity are affected by the intervention. The follow-up period is 2 years.
The purpose of this study is to compare the efficacy of two different approaches (prescribed & self-directed) to the treatment of childhood obesity and their relative impact on child weight status, physical activity, and diet.
The purpose of Challenge! is to determine if adolescents enrolled in a health promotion/ obesity prevention program will have a healthier BMI-for-age z-score and body composition (body fat %), will consume a healthier diet, and engage in higher levels of physical activity compared to those that did not receive the intervention over time.
This project investigates the effect of regular consumption of commercially available processed white beans (5 cups per week) on food intake, body weight, blood pressure, satiety hormones and glycemic response over a 4-week period. We have chosen to provide participants with canned white beans, the most accessible and frequently consumed bean in North America. They are inexpensive, a good source of high quality nutrients and ready to eat. Based upon published literature and short-term studies conducted in our laboratory, we hypothesize that regular consumption of commercially available canned beans will increase satiety and improve the control of food intake, body weight, blood glucose and blood lipids.
The aim of this study is to compare the effects of two different protein supplements (partially hydrolyzed whey protein, PHWP vs. partially hydrolyzed gelatin, PHG) on weight loss in obse individuals with metabolic syndrome (METS). These two supplements will contain equal amounts of protein but differ considerably in their amino acid contents. Whey protein is rich in essential amino acids whereas gelatin is rich in proline. In obese individuals with METS, the hypotheses are: - PHWP will augment fat-mass loss and increase lean-mass to fat-mass ration more than PHG. - PHWP will improve insulin action more than PHG. - PHWP will decrease cardiovascular disease risk more than PHG.
The purpose of the study was to examine the effectiveness of an expert-system, print-based physical activity (PA) intervention delivered to Veterans receiving primary care at the VA Pittsburgh Healthcare System (VAPHS).
H1: The increase in body mass index between baseline and two year follow-up among intervention worksites will be lower than that among control worksites, such that the differential change will be negative on average.
The purpose of this study was to assess the effect of naltrexone SR/bupropion SR (NB) on brain function in response to food cues using functional magnetic resonance imaging in overweight or obese subjects.
This is a pilot and feasibility study to examine a novel intervention using leptin in weight-reduced individuals who have undergone bariatric surgery but still remain obese. Leptin, a peptide hormone secreted from adipose tissue, is a regulator of food intake and energy expenditure. Administration of leptin resulted in profound weight reduction in the few reported cases of obese individuals with genetic leptin deficiency. However, most obese people have increased leptin levels. Such individuals are said to be in a "leptin-resistant" state, whereby administration of physiological concentrations of leptin are ineffective at producing significant weight reduction. Roux-en-Y gastric bypass surgery (RYGBP) is more effective than diet alone in producing long-term reduction of body weight. Yet even after surgery there is a plateau in weight loss though the individual may still be obese and have or be at risk for obesity related morbidities. The investigators have shown that plasma leptin levels are significantly lower in women after RYGBP compared with BMI-matched controls. This state of relative hypoleptinemia or leptin insufficiency suggests that post-RYGBP individuals may be in a "leptin-sensitive" state and, thus, would undergo further weight loss when administered doses of leptin that would not normally result in significant weight reduction. This study will examine the effects of leptin administered by self-injection twice per day on body weight and endocrine function. All individuals will received leptin and placebo and different times during the 34 week study period.
