View clinical trials related to Overweight and Obesity.
Filter by:The management of obesity involves hygienic and dietary measures that include appropriate nutrition and an increase in physical activity (PA). Among the various PA modalities that can be recommended, High-Intensity Interval Training (HIIT) is now recognized as a fun and effective program for promoting fat loss. A meta-analysis conducted by our team suggests a potential influence of the mode of HIIT practice (cycling vs. running) on fat mass (FM) loss. In order to better understand the metabolic adaptations following this type of practice, the investigators propose to compare two isoenergetic HIIT sessions (cycling vs. running) in overweight or obese subjects. The objective is to compare post-recovery (+2h) oxygen consumption, substrate utilization, concurrent energy expenditure and post 24h energy intakes.
The retrospective cohort study will compare the prevalence of sarcopenia and associated factors between older patients who have undergone bariatric surgery and older patients with obesity without previous bariatric surgery.
Obesity has become an important public health issue that leads to insulin resistance, diabetes, hypertension, dyslipidemia, and cardiovascular diseases. Although weight loss with calorie restriction and increased physical activity improve these complications, many people fail these lifestyle interventions. Therefore, pharmacologic agents have been used for weight management in addition to lifestyle interventions. In the past few years, one of the widely used pharmacologic agents for weight management is Glucagon-like peptide 1 receptor agonists (GLP1 RAs). Overall, this class of medications improves both metabolic and cardiovascular profiles while causing weight loss, but their effects can vary between individuals. Therefore, it is essential to understand who will respond best to this therapy. Based on previous research on the interaction between a cell membrane molecule, caveolin-1, and glucagon-like peptide 1 receptor, we hypothesize that genetic variations in the caveolin-1 gene explain the variable cardiometabolic responses.
This 2-site effectiveness trial will test whether a brief dissonance-based obesity prevention program delivered in single sex groups combined with food response and attention training will produce significantly larger weight gain prevention effects than an educational video control condition. An effectiveness trial is important to test whether this program reduces risk for unhealthy weight gain when delivered by real world clinicians under ecologically valid conditions, which is an important step toward broad implementation. A secondary aim focuses on eating disorder symptom prevention effects. A sample of 17-20 year olds with weight concerns (N = 120) will be randomized to single sex Project Health groups with food response and attention training or an educational video control condition. Participants will complete assessments at baseline, posttest, and 6- and 12-month follow ups.
The aim of the current study is to investigate and compare the effectiveness of probiotic supplementation and tDCS stimulation on risky decision-making related to food choices in overweight people. Considering the relatively established communication and interaction between the gut-brain-microbiome axis, the investigators expect that transcranial direct current stimulation and probiotic supplementation can both improve decision-making (decrease risky and impulsive decisions) and increase self-control in overweight people.
The goal of this interventional study is to test whether consumption of Wonderlab probiotics with prebiotics could improve obesity and overweight in Chinese people who are aged 25-45 and overweight. The main question it aims to answer is: - whether the weight of participants can be lost after 10 weeks' intervention 150 participants will be randomized into 3 study groups (50 each group) in the two study sites, who will consume assigned product according to instructions for 10 weeks. Three site visits will be made for each participant and all relevant clinical data will be captured and recorded into CTMS(Clinical Trial Management System) for statistical analysis. Researchers will compare the three groups to conclude whether the Wonderlab study product can improve obesity and overweight over placebo product.
The purpose of this study is to assess the effects of an 8-week supervised high-intensity interval training (HIIT) program (vs. physical activity recommendations according to current guidelines) on a comprehensive panel of circulating sphingolipids in middle-aged females and males at elevated cardiometabolic risk.
Investigators aim to compare the effects of early and late time-restricted feeding on overweight adults with metabolic syndrome
n a retrospective analysis of an exercise training program performed either in the morning or afternoon, we found that the afternoon training group improved their peripheral insulin sensitivity and fasting plasma glucose levels to a greater extent than the morning group. However, underlying mechanisms are unclear. The main objective of this study is to determine whether prolonged exercise training in the afternoon (15:00-17:00 PM) differs from exercise training in the morning (07:00-09:00 AM) in improving insulin sensitivity in individuals with pre-diabetes, and to investigate its underlying mechanisms.
The purpose of the study is to determine associations between fitness status, bacteria in the mouth, and the blood flow to muscle. This study is trying to find out if fitness status impacts the bacteria that are present in the oral microbiome (environment in the mouth) or the ability of the body to send blood to the skeletal muscle. Participants will complete all or some of the following: - A mouth swab to assess the bacteria in their mouths. - Produce a saliva sample into a tube. - Cycle on a bike until you reach maximum effort. - Undergo blood draws - Wear a 24-hour non-invasive device that monitors blood pressure. - Undergo a test to assess blood flow to the muscles measured with an ultrasound. - Drink 70mL (1/3 of a cup) of concentrated beetroot juice once
