The purpose of this pilot study is to compare two strategies intended to improve the health of overweight older adults by improving body composition. One strategy, resistance training, is designed to preserve skeletal muscle mass. The other strategy, the use of a PPAR-γ agonist, is designed to enhance the loss of fat from visceral and skeletal depots. These strategies will be used in conjunction with a hypocaloric diet and will be compared to a hypocaloric diet alone to determine if either of these strategies are superior in reducing visceral fat and preserving muscle mass.
GW869682 causes glucose to be excreted in the urine. The purpose of this study is to see whether enough calories from glucose are excreted in the urine to cause weight loss.
The Metabolic Syndrome (MS) is prevalent in the American population and is strongly associated with premature coronary disease. Lifestyle intervention, primarily exercise and dietary changes, are foundational treatment strategies for independent components of MS, but these interventions have not been thoroughly evaluated in MS. Even with very modest weight loss, in the setting of caloric restriction and exercise, marked improvement MS parameters have been noted. However, it is not known whether it is diet with weight loss or exercise that improves the metabolic derangements associated with MS. We propose a study designed to examine the relative impact of diet or exercise on the components of MS. Furthermore, it is known that psychological factors significantly impact the ability of patients to initiate and sustain lifestyle changes. We will monitor certain psychological states to evaluate their impact on the success of weight loss and sustainability of lifestyle changes throughout this study. Specific Aims: 1.) Evaluate the relative efficacy of diet with weight loss or exercise on improving the markers of metabolic syndrome. 2.) Determine of pre-existing psychological factors influence the effectiveness of diet with weight loss or exercise on the markers of metabolic syndrome. Design: Adult women (> 18 yrs) with a body-mass index (BMI) 30 kg/m2 will be assessed for MS and randomized to one of three groups (n = 34/group), Control (C), diet with weight loss alone (D), or exercise alone (E). The intervention groups will participate in supervised dietary changes designed for weight loss or exercise for 6 months. Anthropomorphic, serologic, and psychological parameters will be monitored and compared using ANOVA. Hypothesis: As indexed by the improvement in the laboratory markers of the components of metabolic syndrome, exercise alone has a more profound positive impact on Metabolic Syndrome then diet with weight loss alone.
This study will investigate the role of weight reduction surgery on the reproductive performance of obese women with ovulation problems. It is hypothesized that surgery offered when other methods of weight reduction have failed, may help restore ovulation.
The purpose of this study is to determine whether adding a peer-based intervention based on an outward bound model is more effective than a standard behavioral weight intervention for helping adolescents lose weight.
We propose to conduct a randomized study of standard behavioral weight-loss treatment to test if using an electronic diary with or without tailored feedback will improve adherence to self-monitoring and subsequently improve weight loss. Subjects will be randomly assigned to different methods to self-monitor food and exercise habits: (1) use of the traditional paper diary , (2) use of a personal digital assistant (PDA), or (3) use of a personal digital assistant that also provides daily feedback.
The majority of patients with Type 2 Diabetes are obese and weight loss is known to improve diabetes outcomes and reduce the need for anti-diabetic medical. This 8-week Telehealth study will compare the effects of standard weight loss advice given in a clinic setting to weight loss advice delivered in the home using an interactive cable television technology called Healthium.
The primary aim of this study is to assess long-term weight loss efficacy of zonisamide relative to placebo in obese patients prescribed a dietary intervention.
Previous work in our laboratory, and many others, has shown that body weight is regulated. When anyone, fat or thin, tries to maintain a reduced body weight, many systems affecting energy balance (skeletal muscle, neuroendocrine, and autonomic systems) conspire to slow metabolic rate thus favoring the regain of lost weight. Individuals with leptin deficiency are remarkably similar to weight-reduced individuals. Their metabolism, thyroid hormones, and sympathetic nervous system activity are all low despite their obesity. While administration of leptin to leptin-deficient humans results in substantial weight loss and increases in energy expenditure. However, leptin administration to leptin-sufficient humans at usual body weight has little or no effect on weight unless given in doses 10-20 times what would be considered to be in the normal physiological range. This study examines the hypothesis that leptin is "read" by various systems regulating energy balance as an indicator of how much energy we have stored and that the body perceives the weight-reduced state as a condition of relative leptin insufficiency. Within this model, restoration of leptin to levels present prior to weight loss should relieve much of the metabolic opposition to keeping weight off. Preliminary studies support this hypothesis.
