Active clinical trials for "Weight Loss"

Introduction: The success rate of weight loss maintenance is limited. Therefore, the purpose of this study is to investigate the maintenance of weight loss and immunometabolic health outcomes after diet-induced weight loss followed by one-year treatment with a glucagon-like peptide-1 receptor agonist (liraglutide), physical exercise, or the combination of both treatments as compared with placebo in individuals with obesity. Methods and analysis: This is an investigator-initiated, randomized, placebo-controlled, parallel group trial. The investigators will enroll women and men (age 18 to 65 years) with obesity (body mass index 32 to 43 kg/m2) to adhere to a very low-calorie diet (800 kcal/day) for eight weeks in order to lose at least 5 % of body weight. Subsequently, participants will be randomized in a 1:1:1:1 ratio to one of four study groups for 52 weeks: 1) placebo, 2) exercise 150 min/week + placebo, 3) liraglutide 3.0 mg/day, and 4) exercise 150 min/week + liraglutide 3.0 mg/day. Re-screening is allowed within the recruitment period. The primary endpoint is change in body weight from randomization to end-of-treatment. Ethics and dissemination: The trial has been approved by the ethical committee of the Capital Region of Denmark (H-16027082) and the Danish Medicines Agency (EudraCT 2015-005585-32). The trial will be conducted in agreement with the Declaration of Helsinki and monitored to follow the guidelines for good clinical practice. Results will be submitted for publication in international peer-reviewed scientific journals.

People often choose certain diets to lose weight or to change their habits or lifestyle. The Dukan diet was created in the '70s and took on importance in the last decade. It is a 4 phase diet similar to the Atkins diet. However, this diet is aggressive in its first phase because it suppresses carbohydrates, the main source of external energy being saturated low-fat protein. Studies of this diet are scarce and have been limited to describing the contribution of micronutrients. In nutritional practice, it is often assumed that a popular high-protein or low-calorie ketogenic diet could cause rapid or unfavourable changes in a patient's weight and body composition. However, the effect of these diets in the short or long term on weight and on body fat, muscle mass and other components is not clear. This means that body composition has not been the main objective when analyzing the effect of a popular diet. For this reason, the meta-analyzes focus on weight change and the absence of body composition data is a limitation of the selected studies. Changes in body composition due to a popular diet should be evaluated with techniques such as DXA. The aim of this study is to analyze the effect of a low-carbohydrate, high-protein diet with energy restriction on weight and body composition using DXA. For this, a randomized controlled study will be used where a group will receive the diet protocol. The control group will have a normal diet, and only one oatmeal drink will be added (55 g of oats in 250 ml of water). The drink will contain 1.6 g of BetaG per serving according to FDA recommendations that correspond to the 50% BetaG required per day.

Malnutrition occurs frequently in patients with cancer during and after radiotherapy to the gastrointestinal (GI) area and can lead to negative outcomes. N-3 fatty acids from fish, especially eicosapentaenoic acid (EPA) may possess anticachectic properties. The aim of this study is to investigate the effect of two nutritional interventions; dietary counselling and an oral nutritional supplement (ONS) containing 2.2 g of the n-3 fatty acid EPA (Forticare®) or standard care, including dietary counselling and protein supplementation when needed.

Over the years, increasing obesity prevalence represents an important threat to national and global public health. Many strategies studied for weight loss have reported that low-carbohydrate diets showed beneficial effects on weight loss for obese patients. However, individual weight losses have varied widely within low-carbohydrate diet groups due to the influence of gut microbiota, which was found in the previous clinical studies of our team (ChiCTR1800015156). Numerous animal studies and clinical trials have evaluated the impact of probiotics on glucose and lipid metabolism as well as weight-loss interventions. However, the effect of the different probiotic strains may play a different role in the same species. Therefore, our team isolated new strains (Lactobacillus reuteri PLBK1，GDMCC No: 60828、Lactobacillus reuteri PLBK2，GDMCC No: 60829、Lactobacillus gasseri PLBK3，GDMCC No: 60830、Lactobacillus acidophilus PLBK4，GDMCC No: 60831、Bifidobacterium lactis PLBK5，GDMCC No: 60832) from the oral cavity, feces or environment of the Chinese race in the previous study. The mixed solid beverage composed of these five strains has local characteristics and meets the requirements of the national standard for food additives, which has obtained the national food production license (SC10632028100205).In our previous animal experiments, the treatment of compound preparation of the above five strains improve insulin resistance and dyslipidemia effectively in obese mice induced by high-fat diet，which obtained significant weight loss . Nevertheless, clinical trials are needed to be carried out to confirm its clinical effect. Therefore, we aimed to conduct a randomized, double-blind, placebo-controlled prospective study on the basis of previous research. In order to evaluate the efficacy and safety, as well as the effect on glucose and lipid metabolism of low-carbohydrate diet combined with probiotics in obese participants, the study will last for 12 weeks. At the same time, Magnetic Resonance Imaging (MRI) will be used to clarify change in body fat distribution, which may provide more clinical evidence for the application of this program in the prevention and treatment of obesity in the future.

Bariatric surgery is an effective method for treatment of obesity. Sleeve gastrectomy is one of surgical methods and became popular in recent years. Weight loss rates after bariatric surgery differs among patients. The exact reason of this difference stays unclear. age, nationality, difference between body composition and type of surgery may be in concern. waist to height ratio has become popular recent years as an indicator of cardiomethabolic status. in this study, investigation of the effect of waist to height ratio differences of patients on weight loss following laparoscopic sleeve gastrectomy as a bariatric surgery.

The goal of this study is to evaluate the effect of three weight management interventions (group phone conference calls, individual phone calls, and enhanced usual care) on weight across 18 months in overweight and obese adults recruited through and treated by rural primary care clinics.

A pre-operative physical conditioning and weight loss intervention (prehabilitation) compared to standard counseling prior to ventral hernia repair for obese patients (BMI 30-40 kg/m2) at a safety-net hospital results in a higher proportion of patients being hernia- and complication-free 2 years after surgical consultation.

The purpose of this study is to determine whether lorcaserin is effective for weight reduction in patients with weight gain as a result of antipsychotic medications.

Idiopathic intracranial hypertension (IIH) is a condition with an unknown cause or causes. The condition is associated with raised pressure in the brain and can cause disabling daily headaches and loss of sight, which can be permanent. The raised brain pressure squashes the nerves supplying the eye (also known as papilloedema) and this can affect vision. Over 90% of patients with IIH are overweight and weight loss is the most effective treatment. Other treatments for IIH have very little current evidence to support their use. Weight loss is difficult to maintain. This trial aims to compare two methods of weight loss, bariatric surgery and the most effective dietary programme commonly available, Weight Watchers, to see which offers the most effective sustainable treatment for IIH. Bariatric surgery is recommended by the NICE clinical guidelines for patients with a Body Mass Index (BMI) of over 40, or over 35 with a co-morbidity. Women suffering from IIH have a BMI on average around 38 and IIH is not recognised as a co-morbidity for bariatric surgery. This trial will recruit 64 women with IIH from Neurology and Ophthalmology clinics in UK NHS Trusts. They will be randomised and 32 participants will be allocated to the dietetic intervention arm, and be enrolled in their local Weight Watchers group. 32 participants will be allocated to the bariatric surgery arm, and will be referred to their local bariatric surgery pathway to receive bariatric surgery. Both groups of participants will be allocated to a treatment arm which is proven to bring about weight loss. Participants will then be followed up for five years, with the most important measurement being their brain pressure after one year of being in the trial. A further 20 obese women who don't suffer from IIH will be recruited to compare the baseline symptoms and biomarkers of those with IIH; they will take no further part in the study. 5 further healthy individuals will be scanned twice in an MRI test group to validate the MRI scan sequence to be used in the trial.

Since overweight and obesity, a risk factor for various diseases, is a prevalent problem in the modern society, it is important to search for new strategies to counteract this. In contrast to in person support, the internet provides a low cost opportunity, which is able to reach a large part of the population. Therefore a web-based weight loss program may be an adequate mean for many people. Now it is hypothesised that a web-based weight loss program is able to support a reduction of body weight and weight-related cardiovascular risk factors effectively and to promote a healthier lifestyle. It is expected that program use, compared to a control group, results in greater reductions in body weight and cardiovascular risk.
