Filter by:This study is designed to test the effects on liver fat of varying fat intake in the presence of fructose or glucose. We hypothesize that higher dietary fat when eaten with fructose as compared to glucose will increase the amount of hepatic lipid as measured by magnetic resonance spectroscopy.
Rates of overweight and obesity are increasing, particularly among individuals aged 18 to 29. An estimated 25-35% of American college and university students are overweight or obese. Contingency Management (CM) is a behavioral intervention that provides tangible rewards for positive behaviors. CM has substantial evidence of efficacy in reducing smoking and drug use and increasing treatment retention and medication compliance. The current study will evaluate the efficacy of a 24-week CM intervention to promote weight loss in overweight and obese university students. Seventy participants with a body mass index (BMI) of 27.0-34.9 will be randomly assigned to one of two conditions: (a) LEARN, a manual guided behavioral weight loss program (Brownell, 2004), with weigh-ins and supportive counseling, or (b) LEARN with weigh-ins and supportive counseling plus CM. Participants in the CM condition will earn chances to win prizes each week in which they lose at least one pound. Once they lose 5% of baseline body weight, they will earn chances to win prizes for weight loss or weight maintenance. Additional chances can be earned by completing activities that promote weight loss. The primary outcomes will be absolute and proportional weight loss from pre- to post-treatment, as well as proportion of participants achieving clinically significant weight loss (>5% of baseline weight) and proportion moving into a lower risk BMI category. Secondary outcomes will include length of retention in the study, increase in physical activity level, and improvement in nutritional quality of diet. Effects of the CM intervention on psychiatric distress and self-efficacy and motivation to engage in activities that promote weight loss will also be assessed. We predict that participants in the CM condition will lose more weight than participants assigned to the LEARN program without CM, and that more CM participants will achieve clinically significant weight loss. We also predict that participants in the CM condition will remain in the program longer, show larger increases in physical activity, show greater improvements in diet quality, and have greater increases in levels of self-efficacy and motivation than comparison group participants. Mediators and moderators of CM outcomes will also be evaluated. If efficacious in promoting weight loss in a college population, CM could help to prevent or delay later development of obesity-related medical problems.
This program aims to help Veterans who take antipsychotic medications lose weight. We use a program based on the American Diabetes Association's "Diabetes Prevention Program," and we have modified it to fit the lifestyles of people with mental illness. All participants are educated about nutrition and cutting down fat intake, how and when to exercise, and the causes of diabetes and how to prevent it. Participants must be Veterans who live within one hour of the Long Beach, West Los Angeles, Sepulveda, or West Los Angeles VA hospitals.
Sixty percent of patients with difficult to control asthma seen in our outpatient clinic are obese. The impact of weight reduction in this subpopulation of asthmatics has not been studied. Our aim is to evaluate the impact of weight reduction on asthma control of these patients.
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 main aim of this study is to analyze and report traditional, patient-centered, and composite intermediate-term outcomes after laparoscopic revision Roux-en-Y gastric bypass surgery for weight recidivism.
The main aim of this study is to analyze and report traditional, patient-centered, and composite intermediate-term outcomes after laparoscopic revision Roux-en-Y gastric bypass surgery for inadequate initial weight loss.
The purpose of this study is to determine whether a daily supplement of vitamin D, taking before and during pregnancy, effects child birth weight, pre- and postpartum complication and bone mineral density during lactation.
RATIONALE: A personalized Internet-based weight-loss program may help improve the quality of life for colorectal cancer survivors. PURPOSE: This randomized phase I trial is studying how well an Internet-based program works in helping colorectal cancer survivors lose weight.
This study is being conducted with the Veterans Affairs National Center for Health Promotion and Disease Prevention (VANCP), which is overseeing the current dissemination of MOVE! (Managing Overweight/Obesity for Veterans Everywhere), a national weight management program for veterans. It will be based at 10 local sites in the national network of VA medical settings and community-based outpatient clinics and will compare two different models for disseminating and implementing MOVE! using a randomized experimental design. One study arm will implement the MOVE* VETS! (Volunteer Education and Tailored Self-management and support) model that includes tailored newsletters and peer counseling MI calls and activities, and the other will receive the standard MOVE! program.
