Filter by:This study plans to evaluate the effect of consuming a symbiotic (probiotic + prebiotic) for 3 months on body weight, body composition, glucose sensitivity, and psychological parameters, as well as on gut and blood microbial composition. Synbiotic consumption is preceded by a 3-day antibiotic course to help ensure the opening of new niches (houses) for the upcoming beneficial bacteria.
This study aims to conduct a feasibility trial to examine the feasibility and acceptability of conducting a randomized controlled trial that evaluates the effect of the weight management intervention on anthropometric measures (body weight and BMI), dietary quality, physical activity levels, physical and psychosocial functioning, self- efficacy for weight loss and quality of life.
The study is a multifaceted approach to investigate the effects of regular consumption of green coffee rich in polyphenols (hydroxycinnamic acids) on weight, body composition, cardiometabolic and inflammatory biomarkers in a sample population of overweight and obese people aimed at identifying a population of responders to green coffee experimenting the highest benefit from this product, and to contribute to the understanding of the influence of some of the main factors on the response to green coffee and their association with the differences between individuals (high-responders vs. low-responders).
The aim of this study is to investigate the effects of I-Fiber Pearl on Body Weight and Body Fat in Obese Adults.
The overall goal is to determine how a sleep extension intervention (increasing time in bed) in individuals who maintain less than 6.5 hours sleep per night affects their plasma ceramides and insulin sensitivity. Participants will undergo a randomized controlled trial, with sleep extension (intervention) and healthy lifestyle (control) groups. The sleep extension is designed to increase participant's time in bed by 2 hours per night. Alternatively, the control group will receive basic health information (e.g., physical activity, goal setting, and nutrition when eating out).
This study is a 2-arm, double blinded, randomised clinical trial where 40 participants will be assigned 1:1 to insulin treatment alone (control) or insulin treatment and tirzepatide treatment for 32 weeks. The primary objective is to demonstrate that tirzepatide treatment, dose incremented to 15mg QW for 32 weeks adjunctive to insulin treatment can reduce body weight in patients with T1D and overweight or obesity when compared to insulin treatment alone. The secondary objective is to demonstrate that tirzepatide treatment, dose incremented to 15mg QW for 32 weeks can improve glycaemic control (measured by hbA1c), improve time in range, reduce insulin requirements, and reduce the severity of comorbidities in people with obesity and T1D. This trial includes a 6 month follow-up period.
Circadian rhythm disruption caused by shift work alters metabolic and hormonal pathways, which accelerates chronic disease onset, leading to decreased quality and quantity of life. Preclinical studies indicate that optimizing nutrient and sleep/rest timing can mitigate these effects. Female nightshift healthcare workers will be recruited to participate in a randomized crossover trial in which participants will be expected to follow the prescribed lifestyle intervention for eight weeks during the first or second eight-week periods of the study.
The aim of this project is to validate a new mindful eating programme adapted to the overweight or obese French population. Recognising the importance of diet in the management of chronic diseases, particularly obesity, and the limitations of traditional weight management approaches, the study focuses on the application of mindful eating. The investigators have adapted a model based on an existing eating disorders programme overseas, taking into account feedback from participants in a qualitative study and the scientific literature. The ultimate aim is to test and validate the effectiveness of this new programme in improving the care of overweight or obese French adults, thereby filling a gap in interventions for this population in France.
This pilot study will compare the effect of combining dietary nitrate and caloric restriction versus dietary nitrate alone. The participant will be contacted, having responded to an advertisement on social media and posters, to attend the screening visit. They will be asked about their health status, suitability for MRI and availability. The investigators will use physical activity and eating attitude questionnaires. The investigators will also measure their height, weight, body mass index (BMI), and blood pressure (BP) and undertake blood tests. If they are eligible, they will be randomised to one of the two arms. The first group will consume nitrate-rich beetroot juice with a calorie-restricted diet for 28 days. The second group will drink the same juice with a weight-maintenance diet for the same period. The food and drinks will be provided. The outcome measures will be measured twice (at the baseline and end visits) to evaluate the change. The primary outcome is the cognitive function. The secondary outcomes are peripheral vascular health (BP and microvascular perfusion), cerebral vascular health (brain blood flow), anthropometry, body composition, and exhaled NO and nitrate concentrations. Also, the feasibility and accessibility of the study will be assessed.
The goal of this clinical trial is to learn about cardiovascular disease risk among adolescent girls with overweight/obesity. The main questions this trial aims to answer are: 1. Does an acceptance-based healthy lifestyle intervention demonstrate more weight loss than a health education intervention? 2. Does an acceptance-based healthy lifestyle intervention show more improvements in participants' physiological, health-related, and psychological factors compared to a health education intervention? Participants in this trial will: 1. Engage in treatment for 6-months, comprising of a mixture of in-person and remote group sessions, occurring at Drexel University or over a video-conferencing platform. 2. Complete various assessments. These include self-reported questionnaires, measures of weight, height, body composition, blood pressure, and blood lipids, and wearing of smart watches to measure sleep and physical activity. Researchers will compare the acceptance-based and health education intervention groups to see if the acceptance-based treatment will indeed be effective in improving participants' health outcomes.
