Filter by:The primary aim of this research project is to determine whether the incorporation of food products containing medium chain triglyceride (MCT) oil in a weight-loss program results in a different degree of weight-loss and total and regional fat mass loss than the incorporation of extra light olive oil. The secondary goals are to test whether there are differences in in metabolic risk profile changes between the 2 diets. We hypothesize that men and women who consumed MCT oil as part of their weight loss program will lose more weight and body fat than those who consume olive oil in their weight loss diet.
To evaluate two different diets and their effects on weight loss and measurements of several risk factors for cardiovascular disease. One diet will be a high saturated fat diet (HSFD) and the other is a low saturated fat diet (LSFD) that limits fat but especially saturated fat as red meat. All participants in this study must eat both diets as this is a randomized cross-over design.
Study hypothesis: High protein diets have been shown to make people full and and help to retent of muscle mass. This study was designed to determine effects of a protein- enriched meal replacement (MR) on weight loss and muscle mass retention by comparison to an equal calorie carbohydrate-enriched MR. Methods: Single blind, placebo-controlled, randomized outpatient weight loss trial in 100 obese men and women comparing two equal calorie meal plans.,1) 2.2 g protein/kg of LBM per day [high protein diet (HP)] or 2) 1.1 g protein/kg LBM/day standard protein diet (SP). Body weight, body composition, and lipid profiles were measured at baseline and 12 weeks.
Obesity is a major cause of premature aging and the second leading cause of preventable mortality in the United States, accounting for approximately 110,000 deaths per year. Financial incentives have been effective in modifying a number of health behaviors but they have rarely been applied to weight loss, and to the best of our knowledge never to weight loss by low-SES obese veterans. We propose testing two different approaches to using financial incentives to encourage weight loss. In the first, we build on previous work showing the effectiveness of 'deposit contracts', in which subjects are given the opportunity to put their own money at risk if they do not lose weight. In this incentive condition, subjects receive a direct payment conditional on daily weight loss, and an optional additional payment based on their own contributions to the deposit contract. We will match their contribution 1:1 to make the option of depositing their own money attractive to this predominantly low SES population. In the second approach we build on our own prior work using lotteries to promote drug adherence. In this incentive condition, participants are entered into a daily lottery, and receive any payoffs they earn from the lottery only if they stay on track with their weight-loss goal. Given their popularity in the general population, lotteries hold the promise of providing a cost-effective means of motivating weight loss and making efforts to lose weight more salient to obese patients.
This is a research study designed to examine the effectiveness of an obesity medication (orlistat) given in addition to behavioral weight loss therapy. Participants will be obese monolingual (Spanish-speaking only) men and women.
The purpose of this study is to demonstrate the efficacy of megestrol acetate in the gain of body weight in patients with primary or mixed Dementia with a weight loss.
The drugs GSK189075 and GW869682 result in increased caloric losses. This study is investigating how if taken over 8 weeks that affects weight loss, food intake and the composition of the body. The body composition (fat,water, lean mass) is determined using a new investigational MR technology.
The goal of this clinical research study is to find the highest tolerable dose of the drug Olanzapine that can be given to patients with advanced cancer who are experiencing weight loss. Researchers want to find out if Olanzapine can help decrease weight loss in patients who are experiencing it because of cancer. How this drug affects performance status, cancer-related symptoms, and nutritional status in patients with advanced cancer will also be studied.
Primary objective: This is a preliminary study to determine if Mirtazapine in comparison to placebo will improve appetite in advanced cancer patients with anorexia and weight loss. An improvement of appetite is defined as a decrease of 2 in the appetite score from baseline on the Edmonton Symptom Assessment Scale (ESAS) at day 15 (+/-3 days). Secondary objective-A: To determine if Mirtazapine in comparison to placebo will improve insomnia ( as measured by Pittsburgh Sleep Quality Index) on day 15 ( +/- 3 days), and day 29 ( +/- 3 days) Secondary objective - B: To determine if Mirtazapine in comparison to placebo will improve other common symptoms such as pain, nausea and fatigue( as measured by ESAS), depression and anxiety ( as measured by Hospital Anxiety and Depression scale), and quality of life ( as measured by Functional Assessment of Anorexia/Cachexia Therapy ) in advanced cancer patients with anorexia/cachexia, on days 15 (+/-3 days), and 29 (+/-3 days) Other Objectives: To provide exploratory data on the effects of Mirtazapine on weight gain, and preservation/gain lean muscle mass ( anthropometric measurements and Bioelectric Impedance), on days 15 (+/-3 days), and 29 (+/-3 days). To provide exploratory data on the effects of a Mirtazapine dose increase to 30 mg on decreased side effects of drug and increased appetite on day 29 (+/-3 days).
Obesity has reached epidemic proportions in the United States with nearly 64% of American adults considered overweight or obese. Weight loss programs that take place at work have proven to be effective at promoting healthy lifestyles. The purpose of this study is to compare the effectiveness of a Web-based weight loss program versus a cash incentive weight loss program among employees at North Carolina universities and colleges.
