Filter by:The purpose of this study was to compare the effects of two different diets (low carbohydrate - LCD and conventional - CONV) on body composition, strength performance, muscle mass and biomarkers of health in overweight adults submitted to resistance training (RT). It has been hypothesized that LCD would produce higher rates of weight loss and that both diets would be useful to maintain muscle mass and strength and biomarkers of health.
The purpose of this study is to assess the drug concentration of Micafungin amongst healthy volunteers having different weight groups.
Summary: - A few studies have explored the effects of providing parents with health information about their children. However, more information is needed about the relationship between awareness of health information and changes in behavior. This study will investigate the impact of health information on choices that parents make about food for their children. - Mothers and fathers with a biological child between the ages of 3-7 years old may be eligible for this study. Participants are recruited from the Washington, DC metropolitan area. - In this study, before visiting the research center, participants will answer online questionnaires about their children's health and eating habits and their own health and eating habits. - At the research center, participants will use a virtual reality model of a buffet to make food choices for their children. Participants will be introduced to the computer-based virtual buffet scenario as a training session to prepare for using the buffet during the experimental context. While in the virtual environment, participants wear a virtual reality helmet that allows them to see the virtual buffet scenario. - After the training session, participants will watch an interactive computer presentation about a health topic. - Participants will then visit the virtual buffet scenario again for the formal session, and will choose a virtual lunch meal for their child as before. - At the end of their visit, participants will complete post-test questionnaires about their experiences during the experiment and other research-related information. - Participants will be asked to complete a follow-up questionnaire online a week after their visit - The total time for the study visit is approximately 90 minutes. The participants children will not be asked to take part in the study. Eligibility: - Men and Women at least 18 years of age who have a biological child between the ages of 3 and 7 who has no major diet-related health conditions, developmental delays, or disabilities. You may not take part in the study if you have a history of seizures and/or are pregnant.
Morbid obesity (MO) is associated with several disorders such as hypertension, type 2 diabetes, dyslipemia and degenerative arthropathy that require pharmacological treatment. Drug bioavailability and metabolism in patients with MO is altered compared to population controls. Bariatric surgery is the gold standard treatment for MO when conventional therapy fails. Bariatric surgery techniques can modify drug absorption in MO patients. These modifications depend on the drug absorption characteristics and on the bariatric surgery technique used. The changes in weight and body composition caused by BS at middle term can alter drug bioavailability and metabolism. The kinetics of the "normalization" process in patients with MO after bariatric surgery is unknown Objectives. To analyze the changes in drug metabolism and pharmacokinetics. To establish drug dosing criteria in the post-intervention period in patients with MO after bariatric surgery. To determine the relationship between changes in drug bioavailability and metabolism in MO after bariatric surgery (longitudinal gastrectomy and Y-roux gastric by-pass).
The purpose of this study is to determine whether subjects following a high protein diet will gain less in weight after smoking cessation compared to subjects following a low fat diet due to the effects of protein on metabolic rate and hunger.
The purpose of this study is to compare standard Behavior Therapy (BT), BT plus Meal Replacements (MR) and a condition focusing on the nutritional changes to the home food environment (HFE) on weight loss, weight loss maintenance, nutritional composition of the diet and psychosocial outcomes. A second aim is to determine the degree to which the specific targets of the experimental interventions do in fact change in the anticipated direction during the intervention and to evaluate whether such changes might account for improvements in weight loss maintenance. This study is important because it could provide the first evidence that the current standard of care for obesity lifestyle treatment could be improved by the addition of MRs or a program of comprehensive nutritional change.
This is the second in a series of pilot interventions we are conducting to assess how principles from behavioral economics can be applied to improve consumers' food choices. In collaboration with Aramark, the food service vendor, we intend to examine if calorie labeling in different formats impacts consumers choice of bottled beverages in hospital cafeterias. Specifically, we will be testing whether signage that conveys to consumers the number of calories in each bottled beverage will increase the number of zero-calorie beverages sold relative to non-zero-calorie beverages. Likewise, we will test whether signage that conveys calories in exercise equivalents increases the sale of zero-calorie beverages. Lastly, we will test if signage conveying standard calorie information in conjunction with exercise equivalents increases the sale of zero-calorie beverages. We will measure the differential effect of each of these three formats for calorie information.
Menopause is characterized by a decrease of estrogen and progesterone levels and is associated with various changes in body composition, including an accumulation of total fat mass, a relocation of adiposity to the abdomen, deterioration of plasma lipid profile, increased risk of type 2 diabetes, and increased oxidative stress. Taken together, these changes increase the risk of developing cardiovascular disease (CVD). Physical activity and hormone-replacement therapy (HRT) have been shown to act in synergy to improve total fat mass in postmenopausal (PM) women. Because the progesterone component of HRT has been associated with an increased CVD risk in older women with a family history of CVD, the use of HRT has become controversial. As a result, a large decrease of the use of HRT in the community has been observed and postmenopausal women (PM) have developed interest in alternative therapies. Among the possibilities, phytoestrogens have shown beneficial effects on menopausal symptoms and plasma lipids. Phytoestrogens are structurally and functionally similar to estradiol (the major estrogen in humans) but found only in plants such as soybean isoflavones. They do not exert any effect on breast cancer or/and endometrial tissue. AIMS To examine the effects of phytoestrogens, exercise and the combination of both on lean body mass, total fat mass, visceral fat, blood lipid profile, oxidative stress markers, antioxidant system, glucose metabolism, and sex-hormone levels in obese PM women. HYPOTHESES Women undergoing a combination of phytoestrogen treatment and an exercise program will display a greater increase in lean body mass, decrease in total and visceral fat mass, improvements in blood lipid profile, decrease in oxidative stress markers, increase in antioxidant system, improvement in glucose metabolism, and increase in sex-hormone levels than those submitted to any or one of the treatments. A total of 120 women will be recruited. There will be 4 groups (30 women/group) undergoing exercise or not and supplemented with phytoestrogens or a placebo. The intervention is planned to last 12 mo. Key variables will be measured at baseline, and after 6 and 12 mo of intervention. Three weekly 1h-sessions of exercise will be held on 3 non-consecutive days. The phytoestrogen supplements will consist of 70 mg/d of soy isoflavones taken as 4 caps/day.
The purpose of this study was to determine the effects of NUTRIOSE® supplementation on body composition, satiety, and determinants of metabolic syndrome in overweight men.
The PILI 'Ohana CBPR partnership implemented a pilot study to determine whether a Family plus Community focused intervention will improve weight loss maintenance compared to Standard follow-up in overweight/obese Native Hawaiian (NH) and other Pacific People (PP) adults (> 18 yr. old) after receiving a standard individual-focused behavioral intervention. The primary hypothesis was that overweight/obese NH and PP adults that undergo a combined family-focused plus community-focused intervention vs. a standard follow-up after receiving a standard individual-focused behavioral intervention will have significantly higher rates of weight loss maintenance.
