Filter by:A phase II, randomized, double-blind, placebo-controlled, in parallel groups clinical trial to assess the safety and efficacy of dietary supplementation with tryptophan to achieve weight loss, and its neuropsychological effects in adolescents with obesity.
Aim: - The overall aims of this study to look at what changes are seen overweight and obese (very overweight) children, as they get thinner. - Specifically the investigators are interested in the chemicals and bacteria that children pass in their urine and stool because looking at how these change as it tells us about how their gut and other bodily systems are adapting. Hypothesis: Metabolic profiling is a useful and accurate tool for observing and monitoring weight loss in children Study plan: - To observe this weight loss process in children, the investigators will be attending a commercial weight loss camp called 'MORElife' which takes place every year in Leeds. This camp is attended by children age 8-17years who are overweight or obese, for between two and five weeks. It aims to help them lose weight through a structured diet, exercise, education and support program. - The investigators plan to, with the consent of the parent and agreement the child ask if they would kindly give us a urine sample at the beginning and end of their time on the camp. For those staying longer than 2 weeks the investigators will also ask for a sample in the middle if possible. - In addition for those children who consent, the investigators will also ask for a small stool (poo) sample at these same time points although there is no obligation to participate at all in the study and it will not affect their time on the camp whatever they decide. - Any children who will be attending the MORElife reunion (arranged by the camp at around 10-12 months after) who agree will be asked for a final urine and stool sample to look at the long-term effects. - Each sample is given a code so as to remain anonymous, frozen and transported to the university laboratory to be analyzed. - With permission and consent the investigators will also collect some information about the children such as, weight and height from the camp coordinators as well as samples of the diet that they will be fed and example of exercise activities to give a full picture so that results can be as accurate as possible.
This study is designed to examine the added benefits of weight loss to an exercise program in older obese Veterans with peripheral arterial disease. The investigators want to determine if weight loss in addition to exercise will 1) improve walking ability to a greater extent than exercise alone and 2) determine the underlying reasons why walking ability improves by measuring blood flow and the amount of muscle in the leg muscles.
The purpose of this study is to carry out a field trial to evaluate the effectiveness and added value of the b-SLIM digital Super Coach in a convenient sample of overweight and obese adults.
The effects of non-nutritive sweetened (NNS) beverages on weight management and psychological indices of appetitive behaviour have not been assessed in both weight loss and maintained weight loss phases over the long term to determine whether NNS beverages may assist in efforts to lose weight and maintain weight loss and how this affects appetite expression (satiety, food choice, craving, ease of dieting etc.). Thus the present research will determine the impact of NNS beverages as compared to water on weight loss and weight loss maintenance, satiation, satiety, cravings for sweet, exercise efforts and mood state across both a period of weight-loss as well as a weight-maintenance phase. To determine if the effects of NNS on appetite are beneficial or detrimental to successful weight management, the study will also systematically compare the effects of NNS beverages, water and caloric beverages (CBs) on appetite (hunger, satiety, liking and wanting) and energy intake (including food choice and caloric compensation) across the whole day during active weight management in a subset of participants.
While some evidence on weight change elicited from commercially available weight loss programs, such as Weight Watchers, is available, there is little evidence evaluating any health-related outcomes that result from losing weight through these programs. In addition, little data exists on the adherence and satisfaction of these types of programs. The purpose of this study is to evaluate body weight and health-related outcomes that are achieved from participating in a Weight Watchers program, along with program adherence and satisfaction. Men and women (N=150) that are participating in Weight Watchers weight loss program will undergo assessments at the University of Pittsburgh to evaluate outcomes related to the Weight Watchers 6 month intervention. Assessment visits, separate from the intervention, will take place at baseline (0 months), 3 months and 6 months for approximately 90 minutes at the Physical Activity and Weight Management Research Center. Participants will be asked to undergo assessments of body weight, height, aerobic stamina, functional fitness, flexibility, and complete a series of questionnaires related to demographics, program satisfaction, sleep quality, happiness, and food cravings. Adherence to the program will be measured by the number of group sessions attended.
Surgery is the only effective treatment for morbid obesity and can be divided into restrictive surgeries (Lap Band and Sleeve gastrectomy), malabsorptive surgeries (Biliary pancreatic deviation and duodenal switch) or a combination of both (RYGBP). This later technique is the most common and most effective surgical procedure performed worldwide and has been processed to be an effective treatment of morbid obesity and its complications, achieving excess weight loss of 65 to 80 % ; 1-2 years after surgery (1,2). Vertical gastric plication is a novel surgical approach for reducing the stomach capacity. Anterior surface plication and greater curvature plication are variations of vertical gastric plication that reduce the gastric capacity through infolding of the anterior surface or greater curvature of the stomach, respectively. These approaches have been tested, with positive results (3,4). A transoral or endoluminal approach (ie, a procedure that requires no incision, because access is granted through the mouth) offers the potential for additional benefit to the patient, because the procedures continue to become more and more minimally invasive. Advances in endoluminal devices are now allowing clinicians the ability to begin exploring bariatric procedures performed via flexible endoscopy. Although these procedures may not be as effective as their surgical counterparts, these less-invasive options may relieve patients of the significant risks associated with surgery (5).
Motivational interviewing and nutritional counseling for weight loss in primary care.
This study aims to develop and demonstrate the effectiveness of a systematic, practical, cost-effective diet-induced weight loss and exercise intervention in both urban and rural communities that can reduce pain and improve other clinical outcomes in knee OA patients. This pragmatic community-based trial will determine if the investigators previous findings translate to real-world settings and will address common concerns about barriers to effectiveness/ implementation.
The purpose of this study is to compare two different techniques of mastopexy with autologous augmentation, the Lower Pole Subglandular Advancement Mastoplasty (LOPOSAM) and Rubins Mastopexy with autologous augmentation, in massive weight loss patients to see if one technique is superior to the other.
