Active clinical trials for "Weight Loss"

Study hypothesis: High protein diets have been shown to make people full and and help to retent of muscle mass. This study was designed to determine effects of a protein- enriched meal replacement (MR) on weight loss and muscle mass retention by comparison to an equal calorie carbohydrate-enriched MR. Methods: Single blind, placebo-controlled, randomized outpatient weight loss trial in 100 obese men and women comparing two equal calorie meal plans.,1) 2.2 g protein/kg of LBM per day [high protein diet (HP)] or 2) 1.1 g protein/kg LBM/day standard protein diet (SP). Body weight, body composition, and lipid profiles were measured at baseline and 12 weeks.

The purpose of this study is to determine if increased intake of low-fat milk products and calcium as part of a calorie restricted diet helps achieve a healthier body weight and body composition and decrease blood glucose levels in people with insulin resistance or type 2 diabetes.

Purpose: To evaluate the efficacy on weight reduction, metabolic parameters and safety of tesofensine versus placebo in obese patients

A 3-arms randomized prospective intervention study to determine the roles of exercise and/or diet on weight loss and weight maintenance in obese preadolescent children 6-11 year-old with BMI> 95th percentile for age and gender. Children were randomly allocated into three groups. The first group underwent an exercise program, the second one underwent both an exercise program and a diet program and the third underwent a diet program alone. The total duration of the intervention is 12 weeks followed by a period of 9 months of follow-up. The effects of the different intervention on weight loss and weight maintenance,body composition, on hormonal components that regulate the caloric balance, on metabolic profile and cardiovascular risk factors and on psychological parameters were also determined.

Control of food intake, size and frequency of meals are critical to the development of obesity. The stomach signals feelings of fullness after a meal and therefore plays a role in control of calorie intake. It is unclear whether the approved appetite reducing drug sibutramine changes the function of the stomach. Differences in the way individuals respond to treatment with the appetite suppressant sibutramine may also explain why some people lose weight while others do not. In a previous study of 48 overweight or obese participants, we preliminarily observed that variation in the gene for the promoter of the serotonin transporter protein was significantly associated with degree of weight loss. This new single center clinical study aims to evaluate the effects of the FDA-approved appetite suppressing medication, sibutramine (MERIDIA)on weight loss and stomach emptying in patients who are overweight or obese. The effect of individual differences in inherited genes that modify serrotonin and noradrenergic receptors on weight reduction with sibutramine will be tested.

This study compared the recently developed Transforming Your Life (TYL) weight loss program to the Diabetes Prevention Program (DPP), considered the "Gold Standard" in behavioral weight loss treatment.

All patients in CMDHB eligible for bariatric surgery are given a weight loss goal prior to surgery. It is unknown what the most effective diet is to lose weight, while still preserving muscle mass. The diet must also be acceptable and adhered to by patients. The aim of this study is to find out if a diet that is higher in protein and lower in carbohydrate than the standard Ministry of Health guidelines will have a greater effect on weight loss, preservation of lean muscle mass, surgical recovery score, adherence and acceptability.

Proposed is a 6-month randomized controlled trial, in 200 overweight or obese Stage I-IIIC breast cancer survivors examining 6-month changes in: 1) body weight, 2) diet, 3) physical activity, and 4)quality of life in women randomized to receive the modified LEAN intervention compared to women randomized to wait-list control (i.e., the wait-list control will receive the modified LEAN intervention after completing the 6-month study).

Lifestyle changes often fail due to loss of motivation. Telemedicine and personal coaching have the potential to support lifestyle change and weight loss. Therefore, the aim of our randomized controlled trial is to examine the effect of telemedicine with and without coaching in comparison to a control group on weight loss in overweight participants.

Very-low calorie diets are relatively safe and effective in inducing significant weight loss, when used in selective individuals and under clinical supervision. However, weight loss maintenance in the long-term remains the main challenge, with many experiencing a significant weight regain. Several compensatory mechanisms are activated under weight reduction, both at the level of energy intake (such as increased appetite) and energy expenditure (such as reduced energy expenditure), and increase the risk of relapse. The main aim of this study is to compare the effect of two multidisciplinary lifestyle interventions on weight loss maintenance at one year, after initial weight loss during 8 weeks very-low calorie diet. Participants will be allocated (non-randomly) to either an outpatient program in the obesity unit of the local hospital, or to an inpatient program consisting of a "continuous care" intervention, with three intermittent stays (each with three-week duration) in a rehabilitation center over a one year period. Moreover, the investigators aim to assess the impact of weight loss (achieved with a very low calorie diet) and weight loss maintenance on compensatory mechanisms activated during weight reduction.
