Filter by:For women diagnosed with breast cancer, dietary, weight loss, and physical activity have been linked with clinically significant weight loss; decreased risk of death; reduced risk of breast cancer recurrence; fewer cardiovascular events; and improved physical function. The objectives of these aims are to a) determine if the TOPS materials and format are possible and accepted by overweight and obese African American breast cancer survivors; b) gather data for sample size calculations for a larger future study. To meet these aims, we will collect data to see if participants enjoyed the TOPS program and suggestions for changes to the program to make it fit their needs. Other methods will measure recruitment, retention, and weight change. Aim 1: Examine the feasibility and acceptability of a national, low-cost, community-based, peer-led, weight loss program (Take Off Pounds Sensibly, TOPS) for overweight and obese African American breast cancer survivors in the local chapter of a national African American breast cancer support group (Sisters Network Triangle North Carolina, SNTNC). Aim 2: Assess the weight change of overweight and obese African American breast cancer survivors after 6 months in the TOPS program to gather data for sample size calculations for a future RCT (randomized controlled trial).
All participants were weighed every week for 24 weeks, wearing light clothes to the nearest 0.1 kg, using a body composition analyzer. Height was determined during the first clinic evaluation using a fixed wall stadiometer to the nearest 0.1 cm, in standing position. Intervention: Participants followed a liquid diet plan during the first week after the endoscopic bariatric procedure (Bioenterics Intragastric Balloon - BIB - or Primary Obesity Surgery Endoluminal - POSE -). Subsequently, subjects were randomly assigned either a Mediterranean-style or a protein diet plan. Energy intake was calculated according to the Spanish Consensus on Bariatric Endoscopy. The hypothesis of this project is to analyze whether the Mediterranean-style diet is more effective compared with the open protein diet plans in weight loss and weight relapse in subjects with obesity who underwent endoscopic bariatric therapies.
Consuming large volumes of water has recently been identified as a common weight loss strategy among U.S. adults. It is a widespread belief that drinking water increases feelings of satiety and reduces food intake, which could contribute to long-term weight maintenance. Many studies have shown support for this, demonstrating water's ability to reduce hunger and energy intake. In some cases, increased water consumption was associated with weight loss. However, the mechanisms of how water affects food intake have been minimally explored. There is potential that the effect of water on reduced food intake and increased satiety is due to individuals' belief that water will reduce their appetite and food intake. The question remains if water expectancy has a meaningful influence on water's ability to reduce food intake. The investigators hypothesize that participants will report less hunger and consume fewer calories when given water and an expectancy that water will affect appetite, compared to a condition when given water and do not expect water to have an effect on appetite. We further hypothesize that calorie intake will not meaningfully differ when participants are given water with no expectancies compared to when given no water. During this experiment, the investigators will vary the presence of water and manipulate expectancies about water's effects on appetite across three conditions: (1) an expectancy and water condition; (2) an expectancy and no water condition; and (3) a no expectancy and water condition. In each condition, participants will engage in a bogus taste test and complete two short cognitive tasks for distraction purposes. In an effort to prevent demand characteristics, this study involves deception. Participants will be told that the research team is interested in testing the effects of three different mint herb variations on attention, coordination, and taste perceptions. After completing the cognitive tasks and taste test, participants will have a 10 minute period to eat as much of the remaining food as they'd like. Food will be weighed before and after this period (without the participant's knowledge) in order to determine caloric intake.
The aim of this randomized controlled trial is to evaluate the effects of a physiotherapist-delivered dietary weight loss program on clinical outcomes among people with knee osteoarthritis (OA) who have overweight or obesity. The primary hypothesis is that a physiotherapist-delivered dietary weight loss plus exercise program will be more effective in achieving weight loss than a physiotherapist-delivered exercise program alone. Approximately 6-9 physiotherapists in Melbourne, Australia will be recruited and trained in weight management for OA patients, as well as trained in how to deliver the specific study interventions. The same therapists will deliver the intervention in both arms of the trial. 88 participants with knee OA will be recruited from the community and randomized into one of the two arms a) diet plus exercise intervention or b) exercise intervention alone. Participants in both groups will be asked to attend 6 consultations with the physiotherapist over 6 months. Questionnaire and laboratory-based outcome measures will be completed by participants at baseline and at the end of the 6 month intervention period. A biostatistician will analyse blinded, de-identified data.
The detrimental effect of overweight and obesity on fecundity has been well documented. The investigators wish to investigate the intervention program for weight loss before fertility treatment. Subsequently to gain knowledge on the effect of overweight/obesity and weight loss on the vaginal microbiome, on DNA damage on sperm cells, on the occurrence of endocrine disruptors in the endometrium, and on the gene expression in the endometrium.
Approximately 20-40% of patients with ulcerative colitis (UC) are obese. The investigators have demonstrated that obesity adversely impacts disease course in patients with UC, leading to higher risk of persistently active disease, surgery, hospitalization, and treatment failure, particularly in biologic-treated patients. Intentional weight loss is effective in improving disease outcomes in patients with inflammatory arthritis, but there is limited data on its impact in UC. While dietary interventions for weight loss have limited efficacy and endoscopic bariatric interventions may be too invasive in patients with UC with active gastrointestinal symptoms, pharmacological weight loss with a highly effective oral agent may be a novel strategy to induce weight loss and augment the efficacy of biologic therapy in UC. Hence, the investigators are conducting a pilot, phase 2A, 22-week, randomized, placebo-controlled clinical trial of phentermine-topiramate in obese patients with active UC starting on a new biologic agent (infliximab, adalimumab, golimumab, vedolizumab). The overall objective is to (1) evaluate the efficacy, safety and tolerability of phentermine-topiramate, and (2) to assess the impact of pharmacological weight loss on clinical outcomes, inflammatory burden and biologic trough concentration in patients with UC. The central hypothesis is that phentermine-topiramate will be safe, effective, and well tolerated in patients with UC, and weight loss would achieve higher rates of clinical and biochemical remission, and higher biologic trough concentration.
This is an interventional research study about clinical, psychosocial, and behavioral factors that impact weight loss, weight maintenance, and cardiovascular disease in socially disadvantaged persons.
This past century witnessed a significant increase in the prevalence of obesity. successful maintenance of weight loss is defined as losing at least 10% of the initial body weight and maintaining it for at least one year. However, keeping the low body weight is rarely maintained, as 80% of people who lost 10% of their body weight will return to their initial weight within a year. Although there is no agreement as to what contributes to the recurrent weight regain phenomenon (also known as 'weight cycling' or 'yo-yo diet'), it is strongly associated with the risk of developing metabolic risk factors and their complications including heart disease and all-cause mortality. Altering the gut microbiota is one method to treat disease states associated with gut bacteria. For instance, fecal microbiota transplant (FMT) or fecal bacteriotherapy, is the process of transferring stool from a healthy donor to another. Although numerous individual microbes have been identified as related to obesity, multiple studies suggest that loss of microbial diversity has a stronger impact on the development of metabolic dysfunction, this diversity may be restored by FMT. This study will determine whether microbiome modulation might be a possible future target against recurrent obesity in humans and whether orally administered FMT from a lean donor, post weight loss might be an effective intervention to prevent weight regain.
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.
Malnutrition occurs frequently in patients with cancer during and after radiotherapy to the gastrointestinal (GI) area and can lead to negative outcomes. N-3 fatty acids from fish, especially eicosapentaenoic acid (EPA) may possess anticachectic properties. The aim of this study is to investigate the effect of two nutritional interventions; dietary counselling and an oral nutritional supplement (ONS) containing 2.2 g of the n-3 fatty acid EPA (Forticare®) or standard care, including dietary counselling and protein supplementation when needed.
