Active clinical trials for "Weight Loss"

A randomized clinical trial comparing the effect on weight reduction and cardiometabolic risk factors of intermittent energy restriction and a isocaloric continuous energy restriction in obese subjects.

A prospective randomized study, including moderately obese patients will be included. Patients will be randomized in 3 groups: PENS of dermatome T6 with an ambulatory self-applied patch + 1200Kcal/day diet PENS of dermatome T6 with conventional procedure + 1200Kcal/day diet Only 1200Kcal/day diet The effect on appetite and weight loss will be investigated.

Obesity is one of the greatest public health challenges of the 21st century. Its prevalence has tripled in many countries of the European Region since the 1980s, and the numbers of those affected continue to rise at an alarming rate. In addition to causing various physical disabilities and psychological problems, excess weight drastically increases a person's risk of developing a number of noncommunicable diseases including cardiovascular disease, cancer and diabetes, in association or not to metabolic syndrome. The risk of developing more than one of these diseases (co-morbidity) also increases with increasing body weight. Every year a growing number of patient tend to suffer of more severe obesity and difficulty in losing weight even with a restricted diet and exercise. Garcinia mangostana (Sphaeranthus indicus extract) has known for its antioxidant properties; new evidence point out some promising effects in the prevention of lipogenesis and the promotion of lipolysis . Currently in the scientific literature there is only one paper, by Stern et al., showing the association of Garcinia mangostana assumption in low-calorie diet. This work has demonstrated a significant reduction in weight loss , compared to the placebo group,due to the use of Garcinia mangostana. Aim of the present study is the evaluation of safety and efficacy of weight loss in severe obese patients. Also cardiometabolic parameters and flogosys serum indicators will be evaluated before and after 6 month therapy of low calory diet alone or in association with Garcinia mangostana extract.

Obstructive sleep apnea (OSA) is a common form of sleep-disordered breathing (SDB). Weight reduction has always been advocated in patients with OSA who are overweight and may lead to improvement in the severity of OSA. Previous study reported a randomized controlled trial of dietician-led lifestyle modification program (LMP) in 104 patients and found that LMP group had significantly more weight loss and reduced OSA severity, and the response was sustained after 8 months. This study is aimed to compare the effect of weight loss or CPAP alone on subclinical inflammation, insulin resistance and blood pressure in patients with obesity and moderate-to-severe obstructive sleep apnea, stratified according to the degree of craniofacial restriction. The study plans to recruit consecutive patients who have been referred to the Respiratory Clinic at the Prince of Wales Hospital with clinical suspicion of sleep-disordered breathing with specific study entry criteria including an age of 18 or more, body mass index (BMI) >25 kg/m2, and moderate to severe OSA diagnosed by home sleep study. Patients having conditions that will affect the serum level of hsCRP will be excluded.

Investigative trial with aim of the description of the hormonal and metabolic response to meals containing different compositions of macronutrients the metabolic response to these test meals in dependance of the hepatic and muscular insulin sensitivity and abdominal adipose tissue and effects of a weight loss on the hormonal response to these test meals containing different compositions of macronutrients Primary endpoint: Glucagon-like-peptide 1 (GLP-1), Glucose dependent insulinotropic peptide (GIP) and Ghrelin response to a nutritive stimulation characterized by different nutritional composition Secondary endpoints: differences of substrate utilization depending on the nutritive composition effects of different hepatic and muscular insulin sensitivity as well as impact of visceral fat mass on the hormonal and metabolic response effect of weight loss on the hormonal and metabolic response to different test meals Study procedure: After primary characterization 50 probands (male and female) will receive 3 different test meals within a randomised (meal order) controlled trial. The three different test meals differ in nutritional composition. During consumption of the test meal a characterization of the endogenous hormonal response and appetite behaviour is performed. A nutritional counselling is performed according to the guidelines of the German Nutrition Society (DGE) to ensure a stable nutritive behaviour in the three days before the test meal administration. After analysis of the hormonal response to these 3 different testmeals follows a weight reduction period over 3 months. Afterwards reevaluation of the probands (again administration of 3 different test meals over a period of 3 weeks) will be performed. Principal aim of the study: Gain of information leading to the understanding of the hormonal regulation of food intake. The individual variability shall be determined with the aim of an identification of patient groups which show various intensities of the responses to different macronutrients.

A phase II, randomized, double-blind, placebo-controlled, in parallel groups clinical trial to assess the safety and efficacy of dietary supplementation with tryptophan to achieve weight loss, and its neuropsychological effects in adolescents with obesity.

The purpose of this study is to compare the effect of a physical activity-enhanced behavioral weight loss intervention, compared to a standard behavioral weight loss intervention in African American women.

The purpose of this study is to learn how to personalize weight loss programs. In this research we will study: Whether a weight loss counselor should decide if the traditional weight loss therapy is working either after 3 or 7 weekly sessions of therapy and For those who haven't lost the expected amount of weight, whether it is more effective to add packaged meals to the traditional weight loss therapy or to change to an enhanced version of behavioral weight loss therapy.

The purpose of this study is to determine the effect of a spousal support enhanced weight loss program on weight loss among African American men.

The purpose of this study is to compare three methods for managing obesity in rural patients, to see which method will result in patients being able to attain their weight loss goal and maintain that weight loss.
