Filter by:To assess, relative to a placebo, the effects of consuming 400 mL/day or 200 mL/day of a vinegar beverage providing either 1,500 mg/day of acetic acid (in two 200 mL doses daily) or 750 mg/day of acetic acid (in one 200 mL dose daily), respectively, for 12 weeks on VAT (MRI). Thus the 2 active comparator arms 400 mL and 200 mL of vinegar will be independently tested compared to placebo.
This study will test whether a culturally-tailored nutrition and exercise intervention designed for African-American women will lead to sustained improvements in exercise and healthy eating through improvements in self-management mediators: mindfulness, stress management, positive reappraisal, self-regulation, and self-efficacy.
The use of dietary amino acids has been explored for therapeutic and safety intervention of obesity and obesity-induced dysfunction. In particular, 3 molecules have been shown to be effective both in the animal model and in humans, in promoting the loss of fat mass, specifically visceral adipose tissue, and in maintaining free fat mass: arginine, glutamine and leucine (and its metabolite beta hydroxy methyl butyrate, HMB). The aim of this study was to evaluate the efficacy in terms of fat mass, in particular Visceral Adipose Tissue reduction, as primary end point, in obese patients following the administration of specific food for special medical purposes (FSMP) for muscle recovery, consisting of arginine, glutamine and HMB. The secondary end point is the evaluation of skin state, by a validate self-reported questionnaire survey to assess skin, after 4- weeks intake of this FSMP.
The primary objective of the trial is to establish the effects of dietary sulfur amino acid (SAA) restriction on body weight, body composition and energy expenditure in humans.
Increased body weight leading to the development and the establishment of overweight and obesity, has a growing detrimental effect on overall health status and quality of life. Latest research has been focusing on the direct influence of dietary habits on body weight regulation and its synergistic effect with genetic predisposition. The synergistic effect of genetic makeup and dietary habits constitute a major contributing factor, specifically in its manifestation on parameters of the cardiometabolic profile of individuals with elevated body weight. In this context, the aim of the present study is to investigate the effect of two hypocaloric diets with different macronutrient content (a high-carbohydrate/low-fat and a high-protein one) on the body weight loss of an overweight and/or obese adult, Greek population. Moreover, the study aims to explore gene-diet interactions between obesity and weight loss- related target genes and adherence to the proposed dietary schemes. It will further examine influences of the aforementioned factors on body composition, anthropometric indices, such as waist circumference, biochemical biomarkers related to cardiometabolic control and parameters of lifestyle, such as sleep quality. More specifically, 300 participants will be allocated into two groups, following either the high-carbohydrate/low-fat diet or the high-protein diet, for a duration of 3 months. Volunteers will participate in in-person meetings, at baseline and at three months after the beginning of the intervention. Anthropometric measurements and collection of blood samples will take place in each meeting. Demographic data and data on family and medical history, dietary habits, adherence to the Mediterranean diet, overall health status and physical activity will be collected at baseline. Participants will be provided with nutritional counselling and support both at the beginning and throughout the intervention. Participants will further report their monthly progress by completing online questionnaires (namely concerning their body weight, overall health status, physical activity and sleep quality), via use of an online assessment tool developed by our team. The effect of the intervention will be evaluated using anthropometric indices, body composition markers and biochemical biomarkers of cardiometabolic control, pre- and post- intervention. Gene-diet interactions will be assessed via genotyping of DNA samples and statistical analyses will take place via statistical packages, such as PLINK v.1.9.
The objective of this study is to design, implement, and pilot a lifestyle-based, 12-week, weight loss program for parents of children with a disability. This weight loss program supports weight loss among parents. It is a first step towards a parent-only approach to promote healthier weight among children with a disability.
The purpose of this study is to establish the proof of concept for a brain serotonin pathway controlling blood glucose control in humans. We will examine whether activation of serotonin receptors by a single dose of sumatriptan (a drug used for the treatment of migraine) can lead to short term changes in blood glucose homeostasis. Thus far, this has been shown only in animal models but no study in humans has directly investigated this research question. Briefly, in this study we will give a single dose of sumatriptan (100 mg) to each participant in a small sample (10 to 12) of overweight or obese, otherwise healthy humans. It will take place in the Translational Research Facility which is embedded in the Cambridge University Hospitals NHS Foundation Trust. The research staff have extensive experience and expertise in the procedures which will be used. The study will involve a screening visit and 2 subsequent visits at which sumatriptan/placebo will be taken and the glucose metabolism will be assessed using a Botnia clamp (3h procedure involving insulin and glucose infusions given intravenously with frequent blood sampling to assess insulin secretion and sensitivity). There will be about 60 days between screening visit and the last visit. The entire study (including the recruitment and data analysis) is expected to complete in about 12 months. If sumatriptan alters glucose control, this might support future testing in disease models i.e. people with type 1 diabetes (T1D) and/or type 2 diabetes (T2D). Ultimately, if successful, either sumatriptan could be repurposed and/or other drugs from this group (triptans) could be developed for diabetes.
Data from Abu Dhabi's Department of Health document that the leading cause of death among the population of the emirate of Abu Dhabi is cardiovascular disease (CVD). Even with significant investment of time and resources, this has not improved over time. CVD was the cause of death in over 39% of deaths occurring in patients above 45 years of age. In those older than 60 years of age, CVD causes more deaths than cancer, respiratory diseases, and infectious disease combined. Eating an unhealthy diet is the leading risk factor for CVD-related deaths and one study estimated that the current diet accounted for 72% of CVD-related deaths in the United Arab Emirates (UAE). Interestingly, the limited intake of whole grains was associated with 22% of CVD-related deaths in the UAE. Other risk factors include consumption of processed meat, red meat, and sugar sweetened beverages. Despite recognition of what constitutes healthy diet and exercise practices by survey participants, barriers exist to lifestyle change. In one UAE study of patients with type 2 diabetes, only 3% of the 390 individuals surveyed met numerous guidelines' weekly recommendations for 150 minutes of moderate intensity aerobic activity or 90 minutes of vigorous aerobic activity. The most common reasons given in that study for not exercising included cultural reasons (29.2%), "exercise is boring" (20.3%), and lack of family support (4.1%). Widespread availability and access to outpatient dieticians has not lowered rates of obesity, overweight, and cardiovascular disease risk factors. To the investigators' knowledge, this would be the first study investigating the effect of a package of family based lifestyle interventions guided by a health coach. This package of interventions would be supported by technology such as a smartphone application to record dietary intake and the use of wearable fitness trackers to track physical activity. The nationals of the UAE (called Emiratis),have retained traditional cultural values, including strong ties to extended family, which may lead to better adherence to family based rather than individual appointments and interventions, which could lower CVD risk.
