Filter by:Prospective, observational, multicenter study based on a registry of patients with obesity and associated comorbidities undergoing a standardized multidisciplinary weight loss method with a 2-year follow-up.
This project is studying whether patients who use MyFitnessPal as an aid to weight loss have more success than patients who are only given traditional medical guidance from the patient's physician.
Excess skin on the abdomen is a common problem for many individuals after massive weight loss. The surgical procedure of abdominoplasty is intended to remove excess skin and improve the shape of the torso in abdomen, in order to address issues such as skin fold eczema, difficulties finding clothing, and psychosocial issues. The investigators will conduct a randomized, controlled trial where individuals with excess skin on the abdomen will be randomized to either standard abdominoplasty or abdominoplasty in combination with liposuction. The investigators will examine the rate of complications, and the functional and aesthetical outcomes of the two methods.
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.
This online pilot weight loss study will explore the feasibility of recruiting individuals to an established online behavioral weight loss program of varying duration (4 months vs. 6 months), We will compare 6-month weight losses between the two programs of shorter and longer duration, respectively, and obtain data to characterize weight maintenance experiences and retention. Both groups will receive the same intervention; the only difference is the number of weeks the group will meet. Both groups will complete follow ups at 2, 4, 6, and 12 months (12 months after the study begins).
The objective of the study is to examine the extent to which diet/lifestyle change programs with a multidisciplinary team (consisting of a dietician, physician and behaviorist/health coach) that develop healthy behaviors before creating a calorie deficit for weight loss will result in greater weight loss and a longer duration of weight maintenance. It intends to compare the extent of weight loss and weight maintenance in participants who will undergo calorie restriction without prior behavioral interventions to participants that will undergo behavioral interventions prior to starting calorie restriction.
The study has two phases. In Phase 1, the investigators will revise and pilot the distress tolerance (DT) protocol that was originally developed and piloted in a previous study (2P20 GM103430, Spas, PI). Despite the 4-week post-intervention treatment outcomes demonstrating the DT protocol's association with smoking cessation and weight loss, several revisions to the DT protocol are important to improve the intervention. First, the investigators will include the overweight/obese smokers' group-level feedback that the investigators collected during the 7-week intervention and at the 4-week post-intervention individual interviews to tailor the DT protocol to meet the unique needs of smokers with excess weight. Subjects from the previous study revealed factors that led to current and/or previous successful smoking cessation and weight loss efforts, barriers to sustaining current and/or previous successful smoking cessation and weight loss efforts, and general feedback about DT intervention for both health risks. The investigators believe revising the DT protocol to include overweight/obese smokers' unique experience with the novel intervention and their acumen about these key factors will improve the intervention and its generalizability to smokers with excess weight. Additional revisions are described elsewhere. After the investigators pilot the revised DT protocol, the investigators will revise the active health control protocol comprised of standard treatment for smoking cessation and weight loss to ensure both protocols equate for intervention contact time. Although both protocols will have some similar content, to avoid any threats to internal validity, no DT-specific material will be included in the control. In Phase 2, the investigators will conduct a two-armed, preliminary randomized controlled trial (RCT) to compare the revised DT protocol's efficacy to the active health control protocol.
The purpose of this study is to determine if a weight loss app (VA MOVE!® Coach App) along with regularly scheduled telephone counseling, will motivate obese people with metabolic syndrome to lose weight and improve the symptoms of the metabolic syndrome, compared to usual weight loss approaches. This study will randomly assign participants to one of two groups, interventional or control. The interventional group will use the app with phone coaching and standard of care for weight loss. The control group will receive standard weight loss care without the app and phone coaching. Weight loss motivation to adopt life-style changes to maintain weight loss and quality of life between the two groups will be compared. The metabolic syndrome (MetS) is a cluster of disorders including high blood pressure, pre-diabetes, the tendency to carry body weight around the waist, and increased fat in the blood. When these problems happen together, there is an increased risk for heart attack, stroke, diabetes and certain cancers. Although the metabolic syndrome is a serious condition, it can be treated with diet, weight loss and increased activity. It can even be reversed using these lifestyle changes. Due to poor success with routine short-term weight loss treatment (group and one-on-one counseling), it is time to address the problem by a different method. Studies have shown feedback devices and weight loss apps have been successful in weight loss and weight maintenance. They are economical (many apps are free), and convenient to use, without attendance at group sessions. Since weight loss is the corner stone for improvement in the symptoms of the MetS, this study will offer a unique approach to support individuals who are committed to losing weight and adopting a healthier lifestyle. Numerous studies demonstrated that feedback via text messaging, and interaction through social networking support groups, in addition to iPhone apps, are all more effective in weight loss measures than group sessions at a hospital site. (Duncan et al., 2011; Greene, Sacks, Piniewski, Kil, & Hahn, 2012; Shaw et al., 2013; Spring et al., 2013). The benefit of these various methods is that they appear to accelerate weight loss and prevent weight re-gain if employed long-term. With technology changing daily, these approaches must be considered an essential adjunct to, or replacement for, traditional group counselling sessions.
The purpose of this registry is to evaluate if sleeve gastrectomy surgery will help with symptoms of delayed gastric emptying for patients suffering from diabetic gastroparesis.
The purpose of this study is to test two versions a weight loss program potentially suitable for implementation in Africa. A successful method would have widespread application in low-income countries, with the potential to improve world health.
