Filter by:The aim of the study will be comparing the effectiveness of two diets: moderate in fat with a high proportion of monounsaturated fatty acids (MUFAs) - the Mediterranean diet (MED) and 2) the low in fat and high in dietary fiber contents the dietary approaches to stop hypertension diet (DASH) on weight maintenance and cardiovascular risks following a recent body weight reduction in centrally obese postmenopausal women. The tested diets will be given ad libitum manner. Moreover, adherence to both prescribed weight-loss maintenance diets will be also evaluated by the plasma concentration of alkylresorcinols (AR) as a possible whole grain wheat/rye dietary biomarker and by the analysis of fatty acids profile in erythrocyte membranes as a dietary biomarker of a fatty acids consumption. The participants of this study will be 150 non-smoking, postmenopausal women with central obesity, who wished to lose weight and have at least one other criterion of metabolic syndrome. The intervention will include 3 phases: Phase I (weeks 1-8), weight loss dietary intervention with 700 kcal/d energy deficit, Phase II (week 9-32), weight loss maintenance intervention for those participants losing ≥10% initial body weight the MED or the DASH diet will be offered in a random manner. The control group will receive oral dietary recommendations based on the Harvard model "Healthy Eating Plate". After this 32 weeks period will be finished, the participants will be discharged to the community with no contact by study personnel, until the 52-weeks follow-up period (Phase III).
The aim of this project is to improve the evidence-base regarding lifestyle and mental health symptoms among fitness instructors. A national cohort of fitness instructors will be invited to participate in this study by responding to an online questionnaire. The questionnaire will consist of items regarding exercise, nutrition, eating disorders, the menstrual cycle, depression, anxiety, body dissatisfaction and satisfaction, drive for muscularity and leanness, and experiences of sexual harassment. Findings from this study will provide an evidence-base for initiatives to improve/optimize mental health among fitness instructors, and also in the process of developing fitness centres to a core partner in public health and health promotion work.
The main purpose of this research study is to determine if the use of a nutritional supplement and exercise improve or worsen cachexia.
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.
Outcomes of treatments for binge eating spectrum eating disorders are yet to yield desirable results, reporting up to 60-70% of patients remaining symptomatic at post-treatment. Adana City Training and Research Hospital Obesity Center is designed to provide multi-disciplinary health care services and training for groups of obese patients seeking professional help. The center includes a physician, dietitian, physiotherapist, psychologist, public relations officer, and a nurse acting as a life coach. Program is planned to carry initial assessment, health screening, necessary medical attention related to obesity, cognitive change, behavioral change, and sustainability activities. The initial assessment part consisted of one on one interviews of the patient with the physician, psychologist, dietitian, physiotherapist, and the nurse. Then, the patient is consulted with an endocrinologist, cardiologist, psychiatrist, and physical therapy and rehabilitation specialist to elucidate the significant factors that resulted in excessive weight gain and barriers in losing. Patients with severe or mismanaged medical conditions, including chronic diseases, neurological diseases, significant affective and psychotic disorders, and substance abuse or addiction disorders were directed to relevant clinics before registration. The patients who completed the screening are arranged into groups and weekly group meetings are planned. In two group meetings, basic medical knowledge and frequently asked questions are discussed. The center staff and the patients get acquinted. In the following twenty weeks, trainings by the physician, dietitian, psychologist and physiotherapist are conducted about medical information about obesity, using the technology to aid weight loss, what, when, how and why to eat, nutrition groups, ration management, water consumption, self-awareness, stress management, obesity and the association between the psychological processes, warming up and mobilization, correct stance and posture, and adequate physical activity. In addition to group meetings, in monthly individual meetings, the progress of the patients are evaluated. During the course of the program the patients with BED reported improvements in BED episodes and increased weight loss rate which give the idea to conduct a study. The primary goal of the study was to analyze the change in the severity of binge eating disorder in patients registered to the program. We expected to show a decrease in the frequency of the BED episodes in all the patients. The secondary goal includes the analysis of the context of the training program to compare the effectiveness of the topics and the methods. The study was a single-arm, prospective, quasi-experimental study with interrupted time-series design. There were no sampling methods; all patients registered to the center program with binge eating disorder and completed the acquaintance step were asked to be included. Inclusion criteria were having registered to the center for training, passed the first three steps, age between 18 to 65 years, a body mass index (BMI) equal to or over 30, and having binge eating disorder. Patients who failed to attend more than four pieces of training and complete a binge eating evaluation were excluded from the study. The training materials were developed by the trainers and edited by the author for the final version before training. The cases were analyzed for the change in the severity of binge eating disorder in the program. The data collection was performed via socio-demographic information form, binge eating disorder evaluation (BEDE) form, and progress record forms. BEDE was a structured form exclusively using DSM-5 BED diagnosis and the severity criteria1. Progress record form included weekly session content that was administered by a physician, dietitian, psychologist, and the physiotherapist and the monthly individual meetings data. BEDE and progress record forms were applied before the trainings that focuses on cognitive change and repeated every four weeks for 20 weeks. The patients were planned to receive 80 hours of training by the physician, dietitian, psychologist, and the physiotherapist.
A pilot study comparing the effects of pea protein versus whey protein on the preservation of muscle mass and functionality in individuals undertaking a weight loss regimen.
Introduction: The success rate of weight loss maintenance is limited. Therefore, the purpose of this study is to investigate the maintenance of weight loss and immunometabolic health outcomes after diet-induced weight loss followed by one-year treatment with a glucagon-like peptide-1 receptor agonist (liraglutide), physical exercise, or the combination of both treatments as compared with placebo in individuals with obesity. Methods and analysis: This is an investigator-initiated, randomized, placebo-controlled, parallel group trial. The investigators will enroll women and men (age 18 to 65 years) with obesity (body mass index 32 to 43 kg/m2) to adhere to a very low-calorie diet (800 kcal/day) for eight weeks in order to lose at least 5 % of body weight. Subsequently, participants will be randomized in a 1:1:1:1 ratio to one of four study groups for 52 weeks: 1) placebo, 2) exercise 150 min/week + placebo, 3) liraglutide 3.0 mg/day, and 4) exercise 150 min/week + liraglutide 3.0 mg/day. Re-screening is allowed within the recruitment period. The primary endpoint is change in body weight from randomization to end-of-treatment. Ethics and dissemination: The trial has been approved by the ethical committee of the Capital Region of Denmark (H-16027082) and the Danish Medicines Agency (EudraCT 2015-005585-32). The trial will be conducted in agreement with the Declaration of Helsinki and monitored to follow the guidelines for good clinical practice. Results will be submitted for publication in international peer-reviewed scientific journals.
The participants will visit the laboratory on 3 occasions, once for a preliminary visit and a further two occasions to complete experimental trials in a randomised order. The experimental trials will consist of cycling under two conditions; HIIE-First followed by Continuous (Trial-A) or Continuous-First followed by HIIE (Trial-B). Participants will be asked to standardise their diet for 24-hours and complete an overnight fast prior to visiting the laboratory. Participants will then complete 60-min of cycling split throughout the day into two 30-min bouts, HIIE or continuous cycling before breakfast followed by a 3.5 hour rest period before completing their remaining 30-min HIIE or Continuous cycling before lunch. Each experimental trail will last approximately 8 hours and begin at 08:00am. Throughout the trial measurements of subjective feelings of appetite, gastric emptying rate, substrate utilisation and regular blood samples will be taken. Post-trial nutritional and well-being questionnaires will be collected at 24-h post. Study hypothesis 1. The order in which continuous and HIIE is undertaken will result in differences in gastric emptying rate after ingesting a semi-sold lunch? 2. Depending on which mode of exercise is undertaken first will result in different gastrointestinal hormone responses, metabolic responses and appetite responses throughout the trial day? 3. Will the order in which different modes of exercise, undertaken within the same day effect nutritional intake and well-being 24-h after both exercise bout have been completed? 4. Is substrate oxidation effected by the order in which multiple exercise bout of different modes are undertaken within the same day.
Aim: The impact of extended antral resection (AR) after laparoscopic sleeve gastrectomy (LSG) on weight loss changes and metabolic response is still not clearly elucidated with conflicting results. The investigator's retrospective cohort study aimed to determine whether AR is superior to antral preservation (AP) regarding weight loss and resolution of co-morbidities. Methods: Patients were divided into two groups according to the distance of gastric division as AR group (2cm from pylorus) and AP group (6cm from pylorus). Postoperative excess weight loss percentile (%EWL) and total body weight loss percentiles (%TBWL) at the end of first, 6th and 12 months were compared. Secondly, metabolic parameters and complications were compared.
One in three college students have overweight or obesity and are in need of brief and simple weight loss interventions that complement their unstructured lifestyles. Implementation intentions, a strategy that connects a goal-aligned behavior to a cue, facilitate goal-attainment for a wide variety of health-behaviors, but have not been tested as a stand-alone treatment for weight loss in students. College students with overweight or obesity (N = 95) were randomized to one of three conditions: an implementation intention group (IMP), an enhanced implementation intention group (IMP+) that included text message reminders and fluency training (i.e., training for speed and accuracy), and a control goal intention group (GOL) for four weeks. Participants completed anthropometric and self-report assessments pre- and post-treatment as well as experience-sampling assessments during the study to assess how implementation intentions contribute more directly to behavior change
