Active clinical trials for "Weight Loss"

The purpose of this study is to compare the effectiveness of Weight Watchers, brief behavioral treatment, and a combination treatment. We hypothesize that a combination treatment will achieve greater weight losses than Weight Watchers alone.

Phase I, 6 weeks: Intensive weight loss 42 obese subjects with type 2 diabetes mellitus or impaired fasting glucose (FBS greater than 100 mg/dl) and a patient at the Nutrition and Weight Management Center at Boston Medical Center will be randomized to receive either an MCT-based or LCT-based liquid diet for a 6 week period (Phase I) to establish compliance followed by a second 6 week period (Phase II). These diets will be isocaloric (1083 kcal/day) and identical except for the quality of the fat. The intervention will be double blinded. The MCT diet will consist of 5 liquid meals using a commercial product plus 34 grams MCT oil (Life Enhancement Products, Inc. Petaluna, CA; 8.3 kcal/gm) added per day to the HMR shakes. The LCT diet will utilize 5 HMR shakes plus 31.5 grams LCT oil (corn oil; 9 kcal/gm) per day. Patients in both groups will be given a list of supplemental foods that are suitable for the study. They may choose to eat up to an additional 400 kcal per day from this list and will be asked to add these to their food records for monitoring of their caloric intake. A dietitian will instruct subjects at a baseline visit on behavior modification and a moderate physical activity program. Baseline testing includes the following: Body composition by DEXA (Hologic); Subcutaneous abdominal adipose tissue biopsy; blood work. Subjects who do not lose 5% of their baseline weight by the end of Phase I will be withdrawn from the study. If subjects do not lose 5% in Phase I, they will be considered inappropriate for a liquid diet, and therefore for the study, and will be discontinued from the study. Phase II, 6 weeks: Continued weight loss program during phase II, subjects will be maintained on the same diet, supplements and exercise program. Once patients enter Phase II, all baseline lab measurements will be repeated. Needle biopsies of subcutaneous abdominal adipose tissue will be obtained at the beginning and at at the end of Phase II. Finger-stick blood glucose levels will be checked weekly. At the end of Phase II, and of the study, fasting blood work will be obtained. At the end of Phase II, the following procedures will be performed: Subcutaneous abdominal adipose tissue biopsy (total = 3). Body composition by DEXA (Hologic) (total = 2).

The purpose of this study is to learn how the amount of protein during moderate weight loss influences bone health. We will also examine how two levels of protein intake affects diet quality.

The drugs GSK189075 and GW869682 result in increased caloric losses. This study is investigating how if taken over 8 weeks that affects weight loss, food intake and the composition of the body. The body composition (fat,water, lean mass) is determined using a new investigational MR technology.

The purpose of this study is to evaluate the safety and effectiveness of fish oil supplements in maintaining weight in people with disease-related weight loss and/or cachexia.

This study compares two types of diet interventions: a low carbohydrate ketogenic diet (Atkins) and a low-fat diet combined with a medication (Orlistat).

The purpose of the study is to tests the hypothesis, that N-acetylcysteine (a thiol-antioxidant)improves the exercise training effect on cancer patients that experience weight loss (cachexia) as assessed by muscle mass and function as well as histomorphology.

The purpose of this study is to determine the effect of weight loss and exercise on physical function, body fat and muscle mass, bone strength, and quality of life.

The study aims to evaluate the effects of ProbioSatys™ on body weight and related parameters in overweight subjects during a 12-week consumption period. In addition, tolerability and safety of ProbioSatys™ will be assessed.

The BEFORE study ((B) EFficacy Of REfigura) is designed to demonstrate the efficacy of REFIGURA®. It is a double-blind, randomized, monocentric study.
