Filter by:Approximately 20 million people in the United States have some form of kidney failure. People with kidney failure have an increased chance of having low levels of high density lipid (HDL), so called "good cholesterol." Patients who are overweight or obese also have low levels of HDL. The investigators are trying to find out whether causes of low HDL are the same in people who are overweight and in patients with kidney failure so that in the future doctors can better treat low HDL cholesterol levels. People with low levels of HDL are more likely to have heart attacks and strokes and are more likely to lose kidney function. This study hope to learn more about how kidney failure causes low HDL cholesterol levels.
Background: Mindfulness-based interventions may be effective in reducing the stress that may increase both obesity and inflammation. Purpose: The purpose of this study was to examine the effects of a mindful eating intervention on weight loss and health-related outcomes. Methods: Thirty-six obese, postmenopausal women were randomized to a six-week Mindful Eating and Living (MEAL) intervention or an active control group (CONT) consisting of nutritional counseling, goal setting, and group support. Weight, body mass index (BMI), waist-hip ratio (WHR), binge eating, interleukin-6 (IL-6) and C-reactive protein (CRP) were assessed at baseline and four follow-up periods up to one year. Results: Multilevel analyses showed that the MEAL group had reductions in weight, BMI, WHR, binge eating, IL-6, and CRP; the CONT group had reductions in weight, BMI, and binge eating. The reductions in binge eating, IL-6, and CRP were greater for the MEAL as compared with the CONT group. Conclusions: This study suggests that a mindfulness-based eating intervention may promote weight loss and reduce a variety of health-related risk factors in post-menopausal women who are obese.
This study will test the effect of liraglutide on cognitive function in HIV-infected overweight or obese subjects with type 2 diabetes.
This project will evaluate the daily intake of whole eggs in the Mediterranean Diet (Med Diet). Cholesterol levels are normally related to cardiovascular disease (CVD) risk. Dietary fat and the total diet makeup are well known modifiers of CVD risk. The Med Diet has been shown to decrease blood lipids (fats) and reduce inflammation. Cholesterol intake from eggs may not be as bad as once thought and, in fact, may help to improve the blood lipid (fat) levels. This study is being done to test how the addition of eggs to a Med Diet affects blood lipids and other risk markers for CVD.
This study will assess the impact of a randomized intervention aimed at increasing consumption of whole grain foods among children from low-income households that participate in the Special Nutrition Assistance Program (SNAP, or "food stamps"). A total of 60 obese children (8 to 16 years) will be recruited from a clinical population (Healthy Eating Active Living Program) at University of California San Francisco (UCSF) Benioff Children's Hospital Oakland. Participants and their caregivers will all receive education about whole grain foods, and will be randomized to either an intervention or control group. The intervention group will receive a monthly reimbursement allotment of up to 10% of their usual SNAP benefit for specific whole grain foods purchased during the three month study period. The control group will not have the financial incentive for purchasing whole grain foods during the 12 week study period. The investigators will assess the feasibility of the intervention, the impact of the intervention on household grocery purchases, and the impact on the child's anthropometrics, dietary intake of whole grain foods (24-hour recall), and markers of metabolic risk.
Obesity is worldwide a public health problem. According to World Health Organization (WHO), overweight and obesity are the fifth death risk factor worldwide. At least 2.8 million adults die each year. Food addiction is one of the causes of obesity that may benefit from new therapeutic options.
This study will determine the effects of supplementing beta-hydroxy-beta-methylbutyrate (HMB) on body composition and strength changes during weight loss. When overweight and obese persons lose weight, and in particular in conjunction with dietary restrictions, muscle, bone mass, and muscle strength are also lost. HMB has been shown to preserve muscle mass and strength, and it is thought that HMB may also preserve muscle, bone, and strength during weight-loss.
Despite the demonstrable health and quality of life benefits, there are unknowns within consequences of obesity surgery. Weight loss composition is poorly understood. The objective is to have a significant loss of body fat and a limited loss of muscular weight. A cohort study in the nutrition unit at Toulouse University Hospital shows that 3 months and 1 year after surgery, there are 2 phenotypes of patients. The first one is called 'little loss' and is defined by a contribution of muscular weight lower than 15% of the total weight loss. The other one is called 'big loss' and is defined by a contribution of muscular weight higher than 15% of the total weight loss. Causes of these different phenotypes are unknown for the moment. Some amino acids have an anabolic potential. Leucine induces a muscular protein synthesis in clinical situations like hepatic cirrhosis, and some populations like new born and older people. Assuming that, a leucine-enriched essential amino acid supplementation will have a benefit effect on the muscular mass. That is testing the influence of the quality of protein consumed, more than the quantity. An anabolic substance (amino acid here) can lead to gain of muscle only if it is associated to regular physical training, all patients will follow a physical training.
This study evaluates the effect of a lifestyle intervention for women with a pregnancy wish who have a high risk on perinatal morbidity because of overweight or obesity. Half of the patients will receive the lifestyle intervention while the other half will receive usual care. It is hypothesized that an effective lifestyle intervention directed towards healthy living, including reduction of overweight or obesity and, if applicable, smoking reduction, health problems in mothers and their offspring can be prevented.
Background: Obesity increasingly affects young women and contributes to increased maternal, fetal and neonatal complications. Maternal obesity contributes to the subsequent development of childhood obesity not only through social and environmental mechanisms but also through biological processes referring to the original concept of the developmental health and disease. Data suggest that management during pregnancy through nutrition counseling and adequate physical activity will help to break the familial vicious circle of obesity. To help program to be effective it is important to understand the factors that modulate participation. However, few studies have been conducted to assess the determinants that influence participation. Goal: The main objective is to analyze 15 factors that influence participation in a program combining physical activity and nutritional counseling among pregnant women with BMI ≥ 25 kg/m2. Secondary objectives are : - to identify the data that influence adherence and to show that assiduous women will have a better control of weight gain and a reduction of maternal and fetal complications. - to understand the biological mechanisms involved Strategy and method: A prospective research evaluating the participation in an educational program, including nutritional support and adequate physical activity, will be offered to overweight and obese pregnant women. The program will last 12 weeks, and will include three workshops on diet of the pregnant and lactating women, and the young child. Physical activity sessions will be offered once a week. Fifteen independent variables likely to influence participation will be analyzed. The association between participation and the risk of maternal and fetal pregnancy complications related to obesity will be analysed. Meanwhile, more fundamental research will be considered to determine of the biological factors involved.
