Active clinical trials for "Overweight"

The purpose of this study is to test the safety and effectiveness of a purified extract of CH-19 Sweet, containing capsinoids.

PF-04620110 is a novel compound proposed for the treatment of Type 2 diabetes mellitus. The primary purpose of this trial is to evaluate the safety and tolerability, pharmacokinetics, and pharmacodynamics, of multiple oral doses of PF-04620110.

The purpose of this study is to evaluate the effectiveness of a life style counseling programme designed for overweight and obese children and their parents in groups compared to traditional individual counseling in the pediatric outpatient clinic and the community. The two interventions are both hospital and community based.

To study once weekly injections of LY2189265 compared to placebo on blood glucose by measuring glycosylated hemoglobin (HbA1c) change from baseline after 16 weeks in overweight Type 2 Diabetes Mellitus participants.

The purpose of the study is to determine whether using a web-based weight loss website can help overweight individuals lose weight.

This study will provide data on two systems for assigning point values to food choices in a diet plan. The primary purpose of this study is to compare the effectiveness of the two systems with regard to changes in body weight.

Objective - A variety of herbal, over-the-counter preparations of tea leaves are said to reduce the rate of absorption of fat ( allegedly via inhibition of pancreatic lipase) and carbohydrate (via inhibition of carbohydrate digestion and blocking of glucose transport by the intestinal mucosa). There has been some study of the ability of these products to reduce the blood glucose increase observed after a carbohydrate meal and to reduce blood cholesterol levels in chronic studies. The purpose of the present study is to objectively determine if one cup of "tea" made from a combination of three types of tea leaves (mulberry, black and green tea) can cause malabsorption of carbohydrate and fat taken in conjunction with the tea. Research Design - The study will consist of a double blind, placebo controlled crossover study in 20 healthy subjects. On one of two days (one week apart) the subjects will ingest a standard meal consisting of 30 g of sucrose (in the tea) and 30 g of starch in the form of white rice plus 10 g of fat as butter. To measure triglyceride absorption, each meal will also contain 250 mg of 13-C labeled triolein. Triolein is a commonly ingested fat consisting of glycerol bound to three oleic acids. 13-C is a stable (non-radioactive) isotope of carbon. On one of the test days the subjects (randomly) will concurrently consume the active preparation, a tea containing extracts of the three types of tea leave described above plus the meal, and on the other test day they will consume the meal with a liquid placebo preparation (warm water, sugar and food coloring). Subjects will provide a breath sample before and at hourly intervals for 8 hours after ingestion of the meal. Carbohydrate malabsorption will be determined by the hydrogen concentration in the breath samples and fat malabsorption by the concentration of 13-CO2 in the breath samples. Clinical Significance - An increase in breath hydrogen indicates carbohydrate malabsoption and a low 13-CO2 indicates lipid malabsorption. Objective evidence that the tea leaf extract actually induces carbohydrate and/or fat malabsorption could provide the basis for further studies.

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.

Insoluble (1,3),(1,6)-beta-D-glucan from bakers yeast are indigestible polysaccharides. Previous studies indicate that the intake of insoluble dietary fiber is strongly associated with reduced risk of type 2 diabetes and cardiovascular disease. However, the mechanisms leading to this phenomenon are largely unknown. There are close relations between metabolic and inflammatory pathways, and a number of hormones, cytokines, signal proteins, bioactive lipids, and transcription factors have been shown to be involved in both systems. Beta-D-glucans have been suggested to play a role as so called biological response modifiers. Studies in animals indicate that even small doses of (1,3),(1,6)-beta-D-glucan may have beneficial effects on immune activity, i.e., by reducing the secretion of inflammatory factors. The investigators hypothesize that the intake of isolated (1,3), (1,6)-beta-D-glucan from bakers yeast improves inflammatory makers and insulin-sensitivity in overweight subjects with increased C-reactive protein concentrations at baseline.

In this 3-month pilot study, we will introduce to 40 adolescents "at risk for overweight" (i.e., a BMI/age >85th percentile) a structured meal plan consisting of meal replacements, fruits, vegetables, whole grains, lean protein and dairy products. We will encourage and invite at least one parent to the scheduled visits, however, no subject will be eliminated because of lack of parental involvement. In this study, we will conduct behavior modification group sessions using lessons which are structured and patterned after the suggestions documented in the LEARNÒ Program for Weight Control. Diet instruction by a registered dietitian will include the appropriate use of meal replacements for a low-fat, low-calorie meal plan. Portion sizes of all foods recommended will be reviewed and a structured meal plan will be developed by the dietitian for subjects to follow. Subjects will return on a weekly basis for behavioral modification groups sessions in conjunction with the liquid meal replacement diet. Blood work and physical examinations will occur pre and post intervention.
