Active clinical trials for "Weight Loss"

The current pilot study will explore the optimal cost-effective treatment configuration for online group-based weight control by focusing on two aspects of our existing treatment program which have significant associated cost and determine which contribute meaningfully to weight loss outcomes. Specifically, we will explore whether adding synchronous group social support (weekly group video chat sessions facilitated by a trained weight loss counselor) to on demand (asynchronous) social support provided through the program discussion board significantly increases weight losses achieved. We will also examine whether detailed feedback on dietary and physical activity self-monitoring records from a counselor enhances weight loss outcomes in comparison with basic feedback. Finally, we will examine the cost efficiency of the treatment constellations. Further, this pilot study will also explore the feasibility of recruiting participants nationally (rather than just locally) and the capture of data electronically (including body weight measurements) without any in-person contact.

This study, involves the implementation and evaluation of a Monday-focused, individually tailored mobile health application to assist overweight or obese adults who would like to achieve a healthful weight. The goal was to evaluate the application of a Monday-focused delivery system for the M-TRIMM2 intervention on participants who worked or lived in areas in or adjacent to Johns Hopkins East Baltimore medical campus.Targeting mobile messaging occurred at strategic intervals throughout each week, with the intent of prompting participants to renew their health resolutions each Monday combined with lifestyle behavioral education.

The specific aims of this study are to determine the efficacy and cost-effectiveness of a weight loss program compared with usual care (control) treatment on 6-month changes in body weight, body fat, serum hormones, and breast tissue markers associated with prognosis in breast cancer survivors.

The purpose of this randomized controlled trial is twofold. First, to examine the efficacy of a 24-session, 6-month family-based behavioral intervention (FBBI) - as compared to a waitlist FBBI group, which later receives the same FBBI - that targets weight loss in adolescents/young adults with intellectual disability aged 14-22 years. Second, to examine the efficacy of a 12-session, 6-month Maintenance intervention that targets maintenance of weight loss in the same population of adolescents/young adults with intellectual disability. The Maintenance condition follows the completion of each FBBI group and involves a re-randomization to either the Maintenance intervention or no further intervention. Primary outcome measures include body weight and Body Mass Index (BMI). Secondary outcome measures include physical activity/sedentary behavior (measured via accelerometry), dietary patterns (3-Day Food Records), and self-efficacy (brief questionnaire). Hypotheses are that: (1) participants in the FBBI condition will lose more weight (and reduced BMI) than participants in the waitlist treatment condition, and that (2) participants in the Maintenance condition will maintain weight lost (and reductions in BMI) or experience less weight regain, as compared with participants who receive no further intervention following FBBI.

The purpose of this study is to evaluate the effect of a hypocaloric diet on biomarkers associated with insulin resistance, metabolic profile and body composition in women with Metabolic Syndrome.

Despite continued research on effective interventions, obesity remains a major public health issue in the United States. Current treatments, including behavioral weight management programs, weight loss surgery, and pharmacotherapy, tend to be high in cost and have limited reach, reducing the ability of these treatments to address the population-wide scope of the obesity epidemic. Recent advances in technology that improve the ease of self-monitoring and provide targeted feedback offer promise to help larger groups of individuals to lose weight. Despite the commercial popularity of these products, however, little research has been conducted to evaluate their impact on excess body weight or to determine how they should ideally be implemented. Two key questions need to be addressed. First, is use of self-monitoring technology sufficient to produce weight loss, or must this technology be combined with interventionist contact? Second, how cost-effective is a technology-based intervention, with and without interventionist contact? The current study is small prospective, randomized pilot study comparing a self-guided self-monitoring condition (SC) to a technology only condition (TECH) and a technology plus interventionist support condition (TECH+INT). All participants will all be given basic weight management information knowledge and randomized to one of three conditions. Participants in the self-guided self-monitoring condition (SC) will receive traditional paper self-monitoring logs, a standard body weight scale, and a pedometer and calorie book; participants in the technology-based condition (TECH) will receive an electronic activity monitor and WiFi-enabled body weight scale, and will track caloric intake via an associated website; and participants in the interventionist contact condition (TECH+INT) will receive the same technology as in the TECH condition, combined with weekly interventionist contact delivered via telephone. We will compare the impact of each condition on weight loss and investigate preliminary cost-effectiveness.

The individual ingredients in IQP-AK-102 have been widely used. Backed by data from several studies demonstrating their efficacy, we are conducting this study to look into the efficacy and safety of this novel combination of three fibres, in appetite regulation.

Obstructive sleep apnea (OSA) can impars body weight reduction by changes in body composition and energy expenditure. The objective of this study is to evaluate the influence of OSA in energy metabolism and body mass loss in obese subjects. Ninety obese volunteers of both genders, 45 diagnosed with OSA and 45 without OSA, will be submitted to a dietary intervention of one months. Volunteers will be distributed into four groups: obese OSA PTN with moderate protein diet (1.6 g / kg protein / day), obese OSA CHO diet (0.8 g / kg protein / day) with standard composition diet, obese NSAOS PTN diet moderate in protein and CHO NSAOS obese standard diet. All groups will be instructed to perform a restricted energy diet (less 30% of daily energy expenditure). At baseline and one month after the beginning of the program the following evaluations will be conducted: total energy expenditure measured by doubly labeled water method, resting energy expenditure and thermic effect of food by calorimetry, polysomnography analysis, body composition by pletysmography, food consumption by three days of food diary, blood collection for analysis of lipid profile, visceral proteins, hormones related to control of body weight and inflammation. As hypothesis we believe that apneic obese individuals have greater difficult in weight loss and loss more free fat mass than the obese no apneic and that diets with more protein can contribute to greater weight loss, better body composition and energy expenditure in these population.

The PILI @ Work project is a 5 year randomized control trial to adapt a weight loss program for the employees of Native Hawaiian-serving organizations in Hawai'i. The study has two specific aims: Specific Aim 1: To adapt and implement a weight loss and weight loss maintenance program in Native Hawaiian-serving organizations, working with employee representatives to determine how the intervention can be best implemented with employees at the worksites. Specific Aim 2: Among employees participating in the program, to test whether weight loss maintenance program in DVD format is as effective as the weight loss maintenance program in a group face to face format in maintaining weight loss for employees who complete weight loss program. The investigators hypothesize that the PILI @ Work interventions can be effectively adapted and implemented in a worksite settings with active participation by employees and employers. The investigators also hypothesize that overweight (BMI ≥ 25) and obese (BMI ≥ 30) employees who complete weight loss portion of the intervention, and are randomized to received the weight loss maintenance intervention via DVD will have similar success at maintaining weight loss compared to those randomized to PILI Maintenance in group meetings or settings. The investigators hypothesize that will will also be true for physical functioning,blood pressure, daily self-weighing, low to moderate fat and low calorie diets, and daily physical activity.
