Active clinical trials for "Overweight"

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 is to evaluate the efficacy of a parent intervention (NOURISH+) aimed at reducing the problem of overweight and obesity in children.

Current research has shown that the use of diabetes management practices aimed at reducing insulin resistance and hyperinsulinemia (such as weight reduction and the administration of oral antidiabetic drugs) in women with PCOS can not only improve glucose and lipid metabolism but can also reverse testosterone abnormalities and restore menstrual cycles. A new medicine called exenatide (Byetta) has been found to reduce body weight, as well as, improve abnormal glucose metabolism in diabetics. This randomized study will compare Exenatide (Byetta) to extended release metformin (Fortamet) to combination therapy (both Byetta and Fortamet) on menstrual cyclicity, hormone profiles and metabolic profiles over a 24-week period in women with PCOS.

The purpose of this study is to examine the effectiveness of the South Beach Diet™ and South Beach Diet™ products compared to a traditional calorie restricted diet.

The purpose of this research study is to learn if a very low carbohydrate (sugar) diet or traditional low fat diet is able to reduce symptoms related to gastroesophageal reflux disease (GERD) in people who are overweight. Patients with GERD may experience all or some of the following symptoms: stomach acid or partially digested food re-entering the esophagus (which is sometimes referred to as heartburn or regurgitation) and belching. In this study, the investigators also hope to find out if acid in the esophagus is reduced more by a low carbohydrate diet than a low fat diet.

The purpose of this study is to compare a diet containing whole grains versus an energy matched diet using refined grains on body composition and metabolism.

Adolescent overweight and obesity have increased dramatically in the past several decades. High schools are well-positioned to deliver weight loss treatment to overweight and obese adolescents, as they have the facilities and staff to deliver a physical activity program, school nurses with the skills to provide counseling, and are easily accessible by adolescents. This exploratory study will test the feasibility and ability of a school-based intervention, consisting of school nurse counseling and a school-based exercise program, to reduce BMI and improve dietary quality, physical activity, and sedentary behaviors in overweight and obese adolescents. If effective, this could prove to be a cost-effective and relatively easy intervention to disseminate widely for significant public health impact.

The prevalence of obesity and Type 2 diabetes has increased dramatically worldwide. Research on Glycemic Index (GI) diets has been largely developed, however the combination with metformin in humans was not investigated yet. We hypothesized that the low-GI diet in combination with metformin would elicit greater improvements on glucose metabolism, lipid profile and body composition on overweight or obese type 1 subjects. This study aims to evaluate the metabolic effects of the adoption of dietary advice to follow caloric restriction high/low GI diets, and low-GI diet associated with metformin on glucose metabolism, lipid profile and body composition on overweight or obese type 1 subjects.

High quality behavioral weight loss programs are not widely accessible. The Internet offers one way to deliver health behavior programs to a wider audience. However, effective weight loss treatments are intensive and program delivery over the Internet may not be capable of duplicating the level of engagement typically generated during traditional in-person treatment. The goal of this study is to test the effectiveness of three weight loss interventions: Internet alone, Internet+periodic in-person support, and in-person alone. The investigators hypothesize that the in-person and internet+in-person interventions will produce better weight loss and maintenance than the internet only group.

The purposes of this study are to determine: The effectiveness of olanzapine as compared to quetiapine in treating and preventing the recurrence of a variety of symptoms of schizophrenia and schizoaffective disorder in patients who are obese or overweight. The safety of olanzapine as compared to quetiapine.
