Filter by:This study is a single-arm behavioral weight loss intervention for emerging adult women with in-person assessments at 0 (baseline) and 4 months (post-treatment) in addition to EMA data collection regarding risk factors known to interfere with program engagement and weight loss in this high-risk population (e.g., sleep, psychological distress, life events).
This research will test the efficacy of a weight management intervention through a three-group randomized trial: mHealth only, mHealth+Community Health Worker (CHW) support, versus control group, among residents of Boston's public housing developments. The mHealth group consists of a 1-year text messaging program to promote diet and physical activity behavior changes and the CHW support consists of monthly phone counseling delivered by a CHW to support the text messaging program. Our hypothesis is that the mHealth+CHW group will be more effective in bringing about weight loss compared to mHealth alone or the assessment only control group. The findings are expected to inform future health promotion efforts among residents in public housing developments.
Body fat (BF) and muscle mass showed opposing association with mortality. Whole-food, plant-based (WFPB) lifestyle programs has been on the rise lately especially due to impressive health benefits. The results of research on the effectiveness of popular weight loss diets in obese subjects showed 20 to 30% loss of lean muscle mass within to the total body weight loss, whereas in the whole-food, plant-based (vegan) diet the loss was up to 42%. Therefore, an open research problem is to find a way how to improve body composition in an effective and healthy way (i.e., losing of excess BF while maintaining muscle mass as much as possible) but still using stric plant-based (vegan) diet. Investigators will perform retrospective analysis of measurements of body composition and phase angle values of aprox. 200 participants who were on a WFPB lifestyle program from 2016 to 2021 and performed two successive measurements (initial and follow up (FU)), without body mass index (BMI) limitation on same medically approved and calibrated bioelectrical impedance (Tanita 780 S MA, Tokyo, Japan) and were not yet included in our previous studies. A WFPB lifestyle program were consisted of nutrition (i), (ii) physical activity and (iii) support system. Primary outcome include the following measures: BF % and FFM and to examine the change from initial values to FU values (by gender), according BMI classification (e.g,, normal, pre-obese and obese) with subanalysis for those participants who lost up to 5 kg/more and those who lost 5 kg or more of body weight.
The DIETAPYR2 study is a randomized controlled crossover trial consisting of two experimental periods each lasting 8 weeks. Enrolled participants were randomly assigned to either a Pyrenean beef-based diet or a conventional chicken-based diet and instructed to consume this meat three times a week. In the first visit the medical history was obtained and anthropometric measurements, blood pressure (systolic and diastolic) and heart rate were taken. The day after the first visit, in the morning, a sample of blood, stool and urine was taken from the participants after an overnight fast. At the time of this visit (period 1), each participant was randomly assigned to a Pyrenean beef diet (intervention group) or a conventional chicken-based diet (control group). After an experimental period of 8 weeks, the participants were invited to carry out the same evaluations as during the first visit. Subsequently, a 5-week washout period was carried out to eliminate the possible residual effects of the first experimental period. After the washout period, the participants were called back for the same assessments during a third visit just before the second experimental period (period 2). During this period, those who were previously on a Pyrenean beef diet (intervention group) were crossed with the conventional chicken diet (control group) and vice versa. Finally, after the second 8-week experimental period, the participants were retested as on previous visits.
Relative Energy Deficiency in Sport (RED-S) characterizes a range of negative health and performance outcomes that result from chronically low energy availability. RED-S concerns high performance junior and senior athletes across Canada and has a prevalence rate of 3-60%. Our ability to assess and diagnose RED-S remains poor. Accordingly, we aim to create the best parameters to diagnose and manage RED-S; along with information of the prevalence and severity across Canada and globally. These outcomes are expected to have a significant positive impact on the health and performance of Canadian athletes in preparation for the Olympic Games in 2022 and beyond.
PhaoeSOL (Microphyt, Baillargues, France) is a microalgae-based nutritional ingredient developed with a patented production process that has New Dietary Ingredient (NDI) status from the FDA (#1120). It is an extract of the microalgae Phaeodactylum tricornutum standardized to 2.0% Fucoxanthin (FX) content by adding a food grade medium-chain triglyceride (MCT)-oil and a tocopherol-rich (Vitamin E) extract (0.5 % w:w). PhaeoSOL is intended for use as a source of the naturally occurring carotenoid, fucoxanthin, in food supplement products for the general population at levels not to exceed 437 mg/person/day for a maximal duration of 30 days of PhaeoSOL (equivalent to 10 mg fucoxanthin/person/day). Prior studies suggest that marine algae and Fucoxanthinol may have anti-obesity, lipid lowering, and glucose management enhancing properties. The purpose of this proof of concept pilot study is to examine whether dietary supplementation of PhaoeSOL enhances the benefits of women participating in an exercise and weight management program.
Many patients would benefit from dietary/nutritional support to better manage their conditions but evaluating current intake in relation to personal targets is labour-intensive and often does not feature as part of clinical consultations. Primary objective: test usability and acceptability of 'myfood24 Health' for monitoring dietary intake in a group of patients. Recruit 60 gastroenterology surgery patient (Leeds) and 60 Tier 3 Weight Management patients (30 Leeds/ 30 York). Randomise to 3 groups 1. usual care 2. myfood24Health 3. myfood24Health plus personalised feedback 'diet optimisation engine' which suggests changes to amounts or types of foods During a 2-month follow-up, patients in group 2 or 3 will be asked to record daily diet in myfood24, including weekend and weekdays and use it a minimum of 4 times. HCPs will be able to review diet/nutrients for group 2 and 3 patients and can support dietary change or nutritional goals, as part of patients' ongoing clinical management, during existing scheduled clinic visits (N.B. not all participants will have a scheduled clinic appointment during the study). 2 months after recruitment, all participants will receive a link to an online feedback questionnaire. At end of study, HPCs will be invited to provide feedback during a 30 minute interview.
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.
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.
In this study, when patients diagnosed with AN started treatment and their weight increased by 10%; On the other hand, it was aimed to compare the changes in serum adipokine levels observed in morbidly obese patients before bariatric surgery and when they lost 10% of their post-op weight with both anthropometric measurements, biochemical parameters, and values of healthy volunteers.
