Effective nutrition strategies for combatting and/or preventing obesity still need to be identified. This has been the case despite the numerous and different approaches that have been taken. Potential targets for combatting/preventing obesity have been identified, but long-term solutions have not emerged. This study uses time restricted feeding to study the role of dietary protein in obesity prevention and/or treatment. The objectives are to determine the role of skeletal muscle mass as a driver of energy-sensing mechanisms and peripheral signals that regulate appetite and energy intake in overweight and obese adults and to determine the effects of protein timing on muscle mass to regulate appetite and energy intake in overweight and obese adults.
In this project, the investigators will perform a multicenter randomised controlled trial to determine whether advice to consume a moderate, whole food-based low-carbohydrate high-fat (LCHF) ad libitum diet (CarbCount program) can produce and maintain equal remission rates of type 2 diabetes (T2D) as a nutritionally complete very-low-calorie formula diet followed by a energy-restrictive (i.e., calorie counting) diet (DiRECT principles). Within the principles of each approach, the dietary goals and change will be adjusted according to individual needs/capabilities conducive to long-term adherence. Furthermore, the investigators aim to determine whether the rate of diet-induced remission is reflected in/can be predicted by baseline or diet-induced changes in glucose variability (e.g., time-in-range measured by continuous glucose monitoring) and other factors such as anthropometric changes and genetic susceptibility. Each center will also conduct locally-lead standalone mechanistic research, including analyses of intra-abdominal/hepatic fat accumulation, adipose tissue biopsies and/or measurements of energy metabolism. Additionally, changes in medication use, nutritional status, cardiovascular disease risk, as well as adverse events, will be monitored.
The OBE-COACH program is an automated online nutritional coaching service that was evaluated in its first version (MXS-CARE program) in a clinical trial coordinated by our team, in type 2 diabetic patients with abdominal obesity. Results have confirmed the efficiency of the program to improve lifestyle habits, including the 4-month diet, and to reduce weight and HbA1c levels. Based on our experience and the scientific literature, the investigators assume that adherence to the program may diminish in the long term to the point of calling into question its efficiency. So IRIADE compagny developed an enhanced program called OBE-COACH. The OBE-COACH program has been specifically designed to facilitate long-term user adherence. The OBE-COACH program, integrates a bidirectional interactive link between the patient and an automated support system (IRIADE-MED system) associated with an inexpensive remote human support. In the TOOLBAR study, the investigators will evaluate the efficiency of the OBE-COACH solution in a population of obese patients or overweight persons with at least one cardiometabolic risk factor. A group of patients will have access to the OBE-COACH program. It will be compared to a control group which will receive an e-learning program with free access to advice sheets via the web, to a menu generator, videos and a catalog of physical activity, (resources made available by the web site www.mangerbouger.fr (public health France, ministry in charge of health) . Indeed, the investigators judged that the loss of patients during follow-up would be greater if e-learning was not offered in the control group.
This study will compare two different ways of giving cagrilintide and semaglutide for treating overweight and obesity. The medicines will either be given together in 1 injection or as 2 separate injections. The aim of the study is to find out how the different ways of injection affect the level of the medicines in the blood. For the first 14 weeks of the study, participants will get cagrilintide and semaglutide as 2 separate injections. Then participants will either switch to getting the medicines as a combined injection or continue to get the separate injections for 8 weeks. Which treatment participants get after the first 14 weeks is decided by chance. Participants will get the study medicines once a week for 22 weeks. A study nurse at the clinic will inject the medicines with a thin needle in participants stomach area. The study will last for about 8 months.Participants will have 28 clinic visits with the study staff. For 4 of these visits, participants will stay in the clinic for 5 nights. Participants will have blood drawn at 21 visits. Participants will have clinical assessments and participants will be asked about their health, medical history and habits including mental health questionnaires. For women: Participants must not be able to become pregnant if they wish to participate in this study.
In the absence of excessive alcohol consumption, increased levels of fat in the liver (>5%) are diagnosed as non-alcoholic fatty liver (NAFL). It has been shown that NAFL is strongly associated with impairments in metabolic health such as hepatic and whole-body insulin resistance. Insulin resistance is seen as the earliest hallmark in the development of type 2 diabetes. Insulin has two main effects on the liver: suppressing endogenous glucose production (EGP) and increasing glucose uptake. While the former has been extensively studied and is known to be impaired in NAFL, no studies have yet examined whether insulin-stimulated hepatic glucose uptake is affected by NAFL. Recent methodological developments allow us to visualize and quantify glucose uptake in any given tissue using dynamic Positron Emission Tomography (PET) with 18Fluorinated glucose tracer (FDG) during insulin stimulation. In the present study, we will in a first instance optimize the insulin-stimulated whole-body PET protocol and apply the dose as reported in the literature 4 megabequerels per kg of body weight (MBq/kg) (±8 mSv) in the first three subjects. It will then be evaluated whether the dose can be decreased in the remaining measurements. Another twelve individuals will then undergo the optimized dynamic PET protocol to assess insulin-stimulated hepatic glucose together with whole-body glucose uptake measures. Liver fat content and composition will be assessed by proton magnetic resonance spectroscopy (1H-MRS). Fasted De Novo Lipogenesis (DNL) will also be measured by deuterated water. Additionally, a two-step clamp will be performed to measure whole-body insulin sensitivity and insulin-stimulated suppression of EGP. The identification of the contributing factors to insulin resistance during the development of NAFL is crucial in order to develop more effective strategies for the prevention and treatment of metabolic disorders.
This prospective study intends to explore the change of cardiac structure and function in the cohort of overweight or obesity patients, and determine the impact of clinical characteristics on cardiac remodeling and mechanics.
The purpose of the study is to compare the effect of high intensity interval training and low intensity training on physical fitness among adult overweight.
The present study is a 100-participant randomized controlled 2-arm parallel trial that employs a metagenomic approach to examine how 8 weeks of supervised moderate-intensity treadmill walking exercise (MWE) for 30-45 min 3 times/week alters the gut microbiome, serum short chain fatty acids, and the cardiometabolic profile, body weight, and body composition of individuals 30-64 years old who have overweight or obesity and have prediabetes.
This phase II trial determines the effect of metformin extended release on the risk for developing lung cancer in overweight/obese patients that are at high-risk for developing lung cancer. Metformin is widely used to treat type II diabetes and has a long history of safety and minimal side effects. At similar dosage, the drug may have potential anti-cancer activity. Metformin use has been associated with improved survival in patients with non-small cell lung carcinoma, a specific type of lung cancer, and it has also been shown to enhance immune mobilization against tumors. This trial aims to see whether metformin extended release as a preventative treatment may lower the chance of developing lung cancer, and whether it may help patients' immune system learn ("reprogram") to lower a certain type of immune cell (called regulatory T cells) that are linked to tumor development.
