Filter by:This is a follow-up research study to determine if there are any differences in the long-term maintenance of two diet groups, the Atkins' diet (low-carbohydrate) or the LEARN program (low-fat). The Atkins' diet continues to get a significant amount of popular attention and very little scientific evaluation. Due to the small amount of scientific data to support a low-carbohydrate diet and given the wide spread use of this type of diet, it is important to evaluate the long-term safety and effectiveness of the Atkins' diet. We will evaluate whether there are any differences between these two groups 3-years after participation in the initial 1-year study period. We will specifically assess weight, cholesterol levels, glucose and insulin levels, and eating habits and mood as we did originally.
The purpose of this study is to examine how obesity and weight loss following bariatric surgery affect reproductive function. The study is particularly interested in how changes in hormones (those produced in the stomach and fat tissue) following weight loss affect reproductive function. Specifically, we, the researchers at Penn State University, propose to characterize reproductive abnormalities in morbidly obese men and women. We hypothesize that morbid obesity leads to reproductive abnormalities in men and women. We plan to examine the short-term effects of alteration in GI hormones after bariatric surgery on reproductive function. We hypothesize that bariatric surgery radically alters GI hormone expression, resulting in immediate changes to the hypothalamic-pituitary-gonadal axis in men and women. Lastly, we, the researchers, plan to examine the long-term effects of weight loss and changes in adipokines on reproductive function. We hypothesize that the changes in adipokine levels resulting from fat mass reduction lead to substantial long-term improvements in reproductive function and fertility. We also hypothesize that there are sexual dimorphisms in adipokine levels following weight loss, with women experiencing larger changes than men.
Weight loss achieved by dieting induces multiple changes. These changes include a decrease in metabolic rate (the rate in which the body burns its calories), an increase in appetite and other physiological and hormonal changes that may be the cause of failure in dieting. Many of these parameters that have never been evaluated when weight is lost after gastric bypass surgery will be tested in this study.
The efficacy of peer counseling for weight loss maintenance is being tested in obese and overweight African American breast cancer survivors.
This study compares two types of diet interventions: a low carbohydrate ketogenic diet (Atkins) and a low-fat diet combined with a medication (Orlistat).
The purpose of this study is to evaluate the safety and effectiveness of fish oil supplements in maintaining weight in people with disease-related weight loss and/or cachexia.
RATIONALE: It is not yet known whether the supplement creatine is effective in increasing weight and improving appetite and quality of life in patients who have cancer. PURPOSE: This randomized phase III trial is studying how well creatine works in increasing weight and improving appetite and quality of life in patients with weight loss caused by cancer.
This study will compare the safety and effectiveness of three popular weight loss plans. These plans will be compared with the USDA Dietary Guidelines.
RATIONALE: Oxandrolone and megestrol may help prevent weight loss and improve quality of life in patients with cancer. It is not yet known whether oxandrolone is more effective than megestrol in preventing weight loss and improving quality of life in patients who are receiving chemotherapy for solid tumors. PURPOSE: This randomized phase III trial is studying oxandrolone to see how well it works compared to megestrol in preventing weight loss and improving quality of life in patients who are receiving chemotherapy for solid tumors.
The goal of this study is to pilot test in a group of overweight-obese individuals the feasibility and acceptability and indications of efficacy of two CAM treatments, qigong, and acupressure-TAT, for improving long term maintenance of weight loss.
