Filter by:The goal of the current study is to determine the role of dairy in similarly preventing weight and fat re-gain in obese adults who have successfully completed a weight loss diet program.240 obese subjects will undergo a meal-replacement-based weight loss plan designed to produce a 10 kg weight loss in 8-12 weeks. Upon achieving the weight loss goal, subjects will be randomly assigned to either a low-dairy or high-dairy eucaloric weight maintenance diet for two years. Macronutrient distribution will be maintained constant and set at approximately the U.S. average. Primary outcomes include changes in body weight, body fat and anatomical distribution of fat (via dual x-ray absorptiometry) and resting metabolic rate and substrate oxidation (via respiratory calorimetry); Secondary outcomes include blood pressure, circulating glucose, insulin, lipids and calcitrophic hormones. on prevention of weight regain in humans has not yet been assessed in clinical trials.
Protein-rich diets appear to show some benefits in promoting weight loss. It is thought that increased intake of leucine may account for some of this effect. This study is designed to assess whether any of the beneficial effects of dietary leucine supplementation observed in mice also apply to humans. Specifically, our team would like to determine whether oral leucine supplementation in overweight/obese humans increases metabolic rate, reduces body weight, improves glucose utilization and/or, reduces circulating fat levels in the blood. We hope that the results obtained from this pilot study will highlight the specific aspects of metabolic improvement associated with increased daily leucine intake. This study will should provide data that can be used to design more definitive trials with regard to dietary leucine supplementation. Hypothesis This pilot study is designed to accomplish the following two goals: 1. to assess whether any of the beneficial effects of dietary leucine supplementation observed in mice also apply in humans. Specifically, we want to determine whether oral leucine supplementation in overweight/obese individuals' increases basal metabolic rate, reduces body weight, improves glucose tolerance and/or insulin sensitivity, and/or reduces circulating Low-density Lipoprotein (LDL)-cholesterol levels. 2. To provide data that can be used to design more definitive trials with regard to dietary leucine supplementation. We hope that the results obtained from this pilot study will highlight the specific aspects of metabolic improvement associated with increased daily leucine intake. This would in turn lead to more rigorous clinical trials involving larger sample sizes, and with diverse populations of different gender, age, and ethnic groups. Future trials may also be directed to determine minimal doses and durations of leucine supplementation that are capable of achieving clinically significant improvement in the cardio-metabolic risk profile in people.
The aim of this study is to measure important components of weight change in patients who underwent bariatric surgery on measures of fat mass and its distribution and fat-free mass (FFM) (bone mineral density, skeletal muscle, and specific organs) at 60 months (T60) and 84 months (T84) post-surgery, and to compare compartment sizes with stable weight controls.
A randomized, double-blind, placebo-controlled, dose-ranging study to examine the safety, tolerability and effect on body weight of a range of doses of metreleptin and pramlintide, each administered by a separate subcutaneous (SC) injection in obese and overweight subjects.
The purpose of this study was twofold: 1) to assess awareness of and adherence to Texas SB42 among a representative sample of public middle schools in Texas; and 2) to assess the impact of SB42 on the frequency of school PE class, the quality of school PE, and prevalence of child self-reported physical activity behaviors and child overweight along the Texas-Mexico border.
The purpose of the blood spot validation portion of the study is to test if measuring female hormone levels in the blood is as accurate through a finger stick, as it is by a blood draw from a vein. The purpose of the feasibility study is to evaluate ovulation occurrence in two populations of oral contraceptive users: heavier and lighter women.
Several hormones involved in body weight regulation increase the subject's ability to burn fat for energy. The purpose of this study is to investigate how burning fat for energy may affect those hormones and body weight in children. The study will also determine if eating a diet higher in protein alters the amount of fat you burn and how these hormones control body weight.
The purpose of this study is to evaluate the effect of SCH 497079 on weight in obese and overweight participants. The primary measure of effectiveness is the change in body weight during treatment. Additional measures include waist circumference and body mass index (BMI). In addition, the safety of SCH 497079 in obese and overweight participants will be evaluated. The primary hypothesis is that treatment with SCH 497079 will be more efficacious than that with placebo with respect to the primary efficacy variable.
This is a randomized clinical trial for evaluate the impact of a nutritional intervention in the weight control of pregnant women according to the nutritional status, and consequently, the reduction of pregnancy complications. The sample of this study will be composed by 318 pregnant women in the pre-natal care unit of the Health Center in Viamão city / Rio Grande do Sul, including women between the 10th and 25th weeks of gestation, aged up to 35 years old. The eligible pregnant women will be invited by the fieldworks to participated in the trial after be informed about the overall aims of the study. These women willing to participate will be randomly allocated to either the intervention or control group. The intervention group received specific guidelines about feeding practices appropriate to each nutritional status. Data on pregnant women will be collected through a questionnaire in both groups, and to assess the food intake, three 24-hour food recall will be applied in the interventional group and two recall in the control group, in initial and final gestational period. In all appointments pregnant women of the two groups will be weight and classified according to Body Mass Index of pre-gestational (BMI). The dietary advices will be elaborated by the author of the project and nutrition graduation students of Federal University of Health Science of Porto Alegre.
Background: Use of variable definitions of exercise and disparate results, emphasize the need of proper randomized controlled trials examining the relationship between physical activity and weight development during pregnancy. So far, only few intervention studies aiming at weight management during pregnancy have been performed (Gray-Donald et al., 2000,Olson et al., 2004,Polley et al., 2002,Kinnunen et al., 2007). Moreover, most of these interventions have focused on how gestational weight gain may be altered through individual counselling combining diet and exercise habits, rather than supervised training. Search on PubMed revealed no randomized controlled trial where the main outcome was to investigate how the effect of supervised structured exercise may reduce the proportion of women gaining more weight than optimal. The aim of the present study is to assess whether a 12-week aerobic exercise program during pregnancy can prevent excessive gestational weight gain. Method: This is a single blind randomized controlled trial to evaluate the effects of a structured, supervised aerobic exercise program on weight gain stabilization in primiparous pregnant women. The aim is to include 100 women. Interested women eligible for the present study will be invited to a pre-test including interview and assessments at the university. The women are examined three times during the study period. The first visit is between 12 and 24 weeks of gestation, the second at week 36-38 and the last 8-12 week after delivery. The exercise program consists of supervised exercise for 60 minutes, performed at least 2 times per week, for 12-16 weeks. Compliance with the training protocol is controlled by the instructors and registrations in the womens personal training diary
