Filter by:The goal of this clinical trial is to evaluate the effect of freeze-dried blueberry powder on the gut microbiome in overweight and obese adults. The main question[s] it aims to answer are: - Does the supplementation of freeze-dried blueberry powder reduce the risk of obesity or lower the weight of people with a high BMI? - Does freeze-dried blueberry powder alter the gut microbiome function? Participants will; - Mix one sachet of Study Product (freeze-dried blueberry powder/placebo) into breakfast/dessert/yoghurt daily for 56 days during the intervention phase. - Partake in 4 site visits over the 14-week period, including an initial screening visit and a follow-up visit after the intervention phase. Researchers will compare the effect of freeze-dried blueberry powder with a placebo in a population comprising overweight and obese adults to see if the gut microbiome is altered and if there is a change in body composition.
The overall objective of this research is to determine the digestive faith and health impact of protein and fiber rich foods in different food matrices in type 2 diabetes risk population. This is achieved by controlled postprandial intervention where plasma amino acids, lipids, glucose metabolism, bile acids and microbial metabolites are evaluated as well as fecal microbiota and metabolites.
This study will evaluate a new form of non-invasive deep brain therapy for food addiction. Low-intensity transcranial focused ultrasound stimulation will first be delivered using a range of stimulation parameters during psychophysical and physiological monitoring. A well-tolerated stimulation protocol will be selected for subsequent testing in a blinded randomized sham-controlled trial. The trial will evaluate brain target engagement using magnetic resonance imaging, Food Cravings Questionnaire-State, and changes in subject's weight over the course of the study.
The goal of the Self-monitoring With Internet Technology to Choose Healthy Diets (SWITCH) study is to examine a 12-week remotely delivered program designed to help adults adopt a healthy dietary lifestyle and lose weight in a diverse cohort of adults with overweight/obesity. The intervention uses a self-determination theory framework to provide a deeper understanding of the factors that influence dietary behavior within the context of tracking. This study incorporates autonomy-supportive strategies to encourage participants to feel more in control of their dietary choices and will provide information and resources to boost participant's competence in achieving their dietary goals. The intervention includes weekly learning modules to support healthy eating and weight loss and daily dietary tracking with visual feedback, all accessible within the SWITCH app.
This project capitalizes on principles of control systems engineering to build a dynamical model that predicts weight change during weight loss maintenance using behavioral, psychosocial, and environmental indicators evaluated in a system identification experiment. A 6-month behavioral obesity treatment will be administered to produce weight loss. Participants losing at least 3% of initial body weight will be followed for an additional 12 months via daily smartphone surveys that incorporates passive sensing to objectively monitor key behaviors. Survey data pertaining to behavioral, psychosocial, and environmental indicators will be used to develop a controller algorithm that can predict when an individual is entering a heightened period of risk for regain and why risk is elevated. Interventions targeting key risk indicators will be randomly administered during the system ID experiment. Survey and passive sensing data documenting the effects of the interventions will likewise drive development of the controller algorithm, allowing it to determine which interventions are most likely to counter risk of regain.
The goal of this study is to collect more information from people with plaque psoriasis and to determine if insulin plays a role in the pathogenesis of psoriasis. The main question it aims to answer is if insulin action is preserved or even enhanced in psoriatic lesions despite insulin resistance elsewhere. Participants with plaque psoriasis will have punch biopsies taken of lesional and non-lesional skin after an overnight fast and then during an oral glucose tolerance test. Biopsy specimens will then be assessed for markers of insulin action.
The main purpose of this study, performed under the master protocol W8M-MC-CWMM (NCT06143956), is to investigate weight management efficacy and safety with LY3841136 compared with placebo in adult participants with obesity or overweight. The study will last about 64 weeks and may include up to 13 visits.
There are set guidelines for weight gain developed by the Institute of Medicine in pregnancy but about three quarters of women gain an inappropriate weight during pregnancy. Many studies have assessed ways to decrease weight gain in these women who gain excess weight, usually through a combination of diet and exercise. Still, often these interventions are difficult to implement, expensive, or have low acceptability. Wearable Fitbit devices have been on the market for years and slowly becoming more inexpensive and easier to use. Previous studies on non-pregnant women have shown that using the device can help reduce weight gain. In addition, small studies in pregnant women have shown they are accurate for measuring steps and have high acceptability and retention rates. The ability of the Fitbit to assess metrics of sleep including sleep duration and quality will also be assessed. This project aims to provide overweight and obese pregnant women at the beginning of their pregnancy with the Fitbit device and with regular follow-up to assess if there is effectiveness in increasing the rate of women who meet weight gain guidelines compared to women without the device along with measuring aspects of sleep.
This study in China is open to adults who are at least 18 years old who are living with overweight or obesity. People with a body mass index (BMI) of 28 kg/m^2 or higher or 24 kg/m^2 or higher with at least 1 weight related problem can join the study. The main purpose of this study is to find out whether a medicine called survodutide helps people with overweight or obesity. 2 different doses of survodutide are tested in this study. Participants are put into 3 groups by chance. Each participant has an equal chance of being in each group. 2 groups get different doses of survodutide. 1 group gets placebo. Participants get survodutide or placebo as injections under the skin once a week for about 19 months. Placebo injections look like survodutide injections but do not contain any medicine. Participants are in the study for about 21 months. During this time, there are 20 visits. 14 visits are in person at the study site. Where possible, 6 visits can be done by video call, or by phone in rare cases. During this time, doctors regularly measure participant's body weight. Results are compared between the survodutide groups and placebo group to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.
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).
