Filter by:Roux-en-Y (RYGB) gastric bypass reduces the size and capacity of the stomach and bypasses a portion of the small intestine which leads to decreased food intake and higher levels of a gut hormone called GLP-1 (glucagon-like-peptide-1). These changes lead to weight loss, improved blood sugars and often remission of type 2 diabetes but most patients do not qualify or want surgery. The investigators are searching for ways to make the beneficial effects of RYGB available to most type 2 diabetes patients rather than a select few that undergo RYGB. The investigators believe that parts of RYGB can be medically reproduced through a combination of diet and medicine. Once weekly injectable GLP-1 medicine that leads to weight loss and improved blood sugar control in type 2 diabetes are now FDA approved. Optifast is a medically supervised diet that safely reduces calorie intake to 800 calories per day for three months by replacing normal meals with specially prepared bars and shakes which leads to weight loss and improved blood sugar control in type 2 diabetes. Normal meals are then gradually reintroduced over 6 weeks and the bars/shakes are stopped. The investigators hypothesize that Optifast (diet) + once weekly GLP-1 will lead to weight loss and improvement in blood sugar control in type 2 diabetes similar to what is seen after RYGB.
This is a cohort study to understand the role of the human metagenome, and associated metabolites, in health and in various diseased states, in particular obesity as well as sarcopenia. Recruited participants will have their fecal, salivary, urine, serum, and in certain instances, mucosal samples taken, for metagenomic sequencing and metabolite testing. We hope to uncover various differences and signatures in the metagenome and metabolome in various diseased states, with potential future therapeutic applications in personalised medicine.

Sarcopenic obesity, characterised by concurrent reduced muscle mass and excess body fat, affects 11% of older adults worldwide, rising to 23% in those over 75. Considering the negative synergistic impact on health, promoting muscle mass gains while reducing fat mass remains a significant challenge, necessitating urgent and effective intervention strategies for managing SO. Exercise and nutrition are the primary interventions recommended for SO. This project aims to evaluate the effects of the EatWellLog App developed by the investigators' team for local older adults, in improving: - their sarcopenic obesity status, measured by all four diagnostic criteria, including grip strength, muscle mass, physical performance and body fat mass (primary outcome), and, - nutritional self-efficacy, nutritional status, dietary quality, health-related quality of life, and adherence to diet and exercise regimens (secondary outcomes), by enhancing the self-management abilities and longer-term adherence to daily diet management among participants in the M-health group using the App, compared to the control group. The EatWellLog App, designed for older adults with SO, incorporating Klasnja and Pratt's five-strategy framework for mobile health (mHealth) applications development to facilitate health behavioural change. This App supports users with SO in managing daily diets that promote gradual weight loss and muscle mass preservation, adhering to the dietary regimen for this population. Forty older adults with SO will be recruited from local community health centres and then randomized to either m-health or control groups. Both groups will receive an 8-week supervised programme separately. The programme consists of personalised dietary modification programme and group-based exercise training which have been tested and used in the investigators' pilot and General Research Fund (GRF) project. Additionally, only the m-health group will be instructed to use the App for daily diet self-management. Participants will be assessed on a variety of outcomes immediately after the 8-week supervised programme (T1), which will be compared to the baseline (T0). To explore the possible long-term effects of the intervention, other measurements will be conducted at 3-(T2) and 6-(T3) months after the supervised programme, which will be compared with those conducted at T0.
The clinical trial aims to evaluate the efficacy and safety of acupuncture on weight loss and changes of glucose and lipid metabolism in obese adults with pre-diabetes.
Pep19 is a naturally occurring peptide (protein) that triggers loss of body fat. It has been certified Generally Recognized as Safe (GRAS) at up to 3.8 grams per day and may be included in various foods. Pep19 has no effect on the brain, heart, pancreas or skeletal muscle. It is highly purified, not allergenic or mutagenic, and free of microbes, metals and other contaminants. Preliminary, open-label, uncontrolled studies have shown that Pep19 is well tolerated in rodents, dogs, and humans. This placebo-controlled study will evaluate the effects of two doses of Pep19™ -- 2 mg and 5 mg - on quality of life and sleep quality in obese subjects.
The primary purpose of this project is to observe the effects of Cognitive Behavioral Psychotherapy-based weight-loss mobile application (Bi' Kilo) in 4 essential areas (Anthropometric, Biochemical, Psychometric, Cognitive) in overweight and obese individuals and to test whether these effects will persist after ten weeks. In this context, the original value of the proposed study is that a mobile application will be produced that is suitable for the culture and whose effectiveness has been scientifically proven. In our current project proposal, the measurements of the participants will be evaluated holistically together with both tests and inventories, as well as physical measurements and biochemical data. In this study, the usability of the mobile application to be developed will also be evaluated and reported. The study group of the research will consist of overweight and obese individuals. The first stage will be a pilot study to identify the shortcomings of the Bi'Kilo mobile application. After eliminating the deficiencies of the Bi' Kilo mobile application, a working group will be formed in the second phase of the research. At this stage, the sample will be divided into two different groups within the scope of the study and a study group and a control group will be formed. The study consists of three phases as preparation, implementation, and follow-up. Measurements of the participants will be made at the beginning (Anthropometric, Biochemical, Psychometric, Cognitive), at the end of the six-week implementation phase (Anthropometric), and at the end of the four-week follow-up phase (Anthropometric, Biochemical, Psychometric, Cognitive).
Though the Mississippi Delta has a rich agricultural history and some of the nation's most fertile soil, residents have experienced the legacy of slavery and economic exploitation through food insecurity and poverty for generations. This project focuses on Bolivar, Washington, and Sunflower, contiguous counties in the Delta that are designated as health disparity populations. Over 65% of the 100,000 residents are Black/African American and ~30% live at or below the poverty level. Obesity rates are high and the rate of diabetes is almost double the national average. Tufts University received a grant from the National Institute of Minority Health and Health Disparities to develop, test, and evaluate a Food is Medicine program in Mississippi. The Delta Growing a Resilient, Enriching, Equitable, Nourishing food System (GREENS) Food is Medicine (FIM) Project, is a collaborative project in Bolivar, Washington, and Sunflower counties in Mississippi. The intervention involves regularly distributed fruit and vegetable produce boxes as well as nutrition education materials to the intervention group. The control group will receive produce boxes later, after they complete study activities. The project's primary goal is to improve health outcomes by creating a FIM intervention. The Delta GREENS FIM Project aims to become a model for promoting nutrition security and management of chronic conditions in varied communities nationwide.
We aimed to investigate visceral adiposity index (VAI) in patients with different phenotype of policystic ovary syndrome (PCOS) and to compare healthy controls.
This study will use a 2 x 2 factorial design to test impact of two intervention strategies (bottle size and bottle opacity) on infant weight gain.
