Filter by:The feasibility study was conducted using a mixed-methods single group, pre and post-test design (Quasi experiment) approach. The investigator assessed if a weight reduction program using WhatsApp and peer support would work well enough to conduct a larger study. The investigator conducted the study in an urban slum (Azam Basti) in Karachi, Pakistan and enrolled 50 participants, along with participant nominated peers from the same family. Initial eligibility was assessed over the phone. Those who met the initial eligibility were visited to assess eligibility in terms of BMI (23 kg/m2 and above). Height was measured in centimeters (cm) and weight in kilograms (kgs) using a digital weighing scale. Both values were entered into the web-based calculator to calculate BMI. Participants with a BMI of 23 kg/m2 and above were enrolled and written informed consent was obtained. The participants then nominated one peer from the family. Peer eligibility was assessed and written informed consent was obtained. Once the participants and peers were enrolled in the study, the baseline assessments were completed. During the baseline assessments, participants were interviewed for sociodemographic and health-related information, 24-hour dietary recall, and Global Physical Activity Questionnaire (GPAQ). Peers were also interviewed for sociodemographic information. After the baseline assessment, the participants and peers received lifestyle modification education through WhatsApp voice calls for three days and then once monthly for one year delivered by a trained nutritionist. The intervention was delivered mostly in groups. The peer-supported lifestyle modification intervention was developed with the aim of helping participants adopt healthier lifestyles by making dietary changes, increasing physical activity, and achieving a weight loss goal of 5% of their initial body weight. Additionally, the intervention aimed to prevent weight gain among participants. The participants were followed-up for one year. Participants weight (kg), diet through 24-hour dietary recall, and physical activity through Global Physical Activity Questionnaire (GPAQ) were assessed every month. Social support questionnaire was also asked from participants at 3, 6, 9, and 12 months. The investigator also conducted in-depth interviews at the end of the study with study participants and peers to understand the barriers, facilitators, and experiences of the lifestyle modification intervention program.
The purpose of this study is to test a new weight loss intervention designed for cancer survivors who have heart disease or cardiometabolic conditions. The investigators want to determine whether this study is feasible and acceptable to participants. The investigators also want to learn more about how cancer survivors take their medications.
In post-menopause, most women gain weight, and obesity rates are more prevalent in this particular group. In addition, there is an increased risk of cardiovascular disease, cancer, and diabetes. Given that this weight gain can be related to risk behaviours, healthy weight management (such as an increase in physical activity or healthy eating) is crucial to promote a healthy weight and well-being. The ME-WEL (MEnopause and WEigth Loss) project (ref. SFRH/BD/144525/2019), entails an eHealth intervention for weight management and well-being in post-menopausal women with overweight or obesity, based on two theoretical models of behavioral change - the Health Action Process Approach (HAPA), and the Health Belief Model (HBM), and applying the Behaviour Change Techniques Taxonomy (BCTT). This group's eHealth intervention lasts 8 weeks. Each week there is a different theme to be addressed, taking into account the behavioral change models mechanisms, in articulation with different BCT´s. Subjective well-being, self-esteem, weight loss, implementation of weight management strategies, and changes in eating behavior and physical activity/exercise were evaluated, through follow-ups at 3- and 6- post-intervention.
The purpose of this study will be to examine the effectiveness of an application-based lifestyle change program on body composition, body shape, body, image, and self-esteem in females following a 6-week period. The study will be carried out in a randomized, placebo-controlled, parallel manner. Participants will be stratified into quartiles based on their body mass indices during screening and prior to baseline testing. Participants from each quartile will be randomly divided by into experimental or control conditions. Following randomization, participants will be baseline assessed on their body composition using a whole body Dual Energy X-Ray Absorptiometry scan, on their subjective measures of body shape and image using a variety of questionnaires, blood chemistry panel, and lower-body strength using a isometric mid-thigh pull dynamometer. Following baseline testing, participants will undergo 6-weeks of following their respective condition. Participants will be instructed to follow their group-specific guidelines for the 6-week period to the best of their ability. Body shape and image questionnaires and assessments of body composition, blood chemistry, and lower-body strength will be conducted following the week 6 to conclude the study.
Gastric myoelectric, inflammatory, and hormonal responses, body compositional, energy expenditure, and metabolic changes during the development of obesity and the weight loss process are underinvestigated. This project studied the myoelectrical inflammatory and hormonal responses of the stomach, in addition to energy expenditure and body composition changes during weight loss via bariatric surgery and lifestyle intervention.
In a previous study (NCT04081337), 55 participants with obesity participated on a 18-week lifestyle intervention to reduce their body weight, targeting 10% body weight loss. The participants received tirzepatide (15mg after titration) or placebo during the weight loss intervention. Before and after the lifestyle intervention, energy expenditure (48-h room indirect calorimetry) and body weight and composition (dual-X-ray absorptiometry) were measured, thus enabling the assessment of metabolic adaptation. In this study, participants having provided their consent to be re-contacted will be invited to attend the research center 12,18 and 24 months after completing the lifestyle intervention. Body weight and composition will be measured, aiming to explore the association between metabolic adaptation and changes in body weight and composition after a weight loss intervention. In addition, we will explore whether weight and fat mass changes are different between groups, and whether these effects are mediated by metabolic adaptation.
The aim of this randomized, parallel, two-arm, placebo-controlled, double-blind, multicenter clinical trial is to evaluate the efficacy of a dietary supplement on weight loss and psychological well-being in overweight individuals.
The primary objective of this study is to investigate the safety and efficacy of a bone broth diet on weight loss in obese adults. The change in weight and body mass index (BMI) following the bone broth diet will be measured from baseline at Days 22 and 50. Additionally, the safety and tolerability of the bone broth diet will be measured by the occurrence of post-emergent adverse events (AEs).
The goal of this pilot trial is to learn about the optimal intensity level of goals in a digital weight loss intervention among adults with overweight or obesity. The main questions of the study are to assess the feasibility and acceptability of different goal intensities across four domains (calorie goal, step goal, eating window goal, red zone food goal). The investigators will recruit 32 total participants to the trial. Recruitment will occur through remote channels. Interested individuals will be directed to an online screening questionnaire; those who are eligible will then be invited to attend an initial remote session with study personnel to ensure interest and eligibility in the study. The weight loss intervention will last 10 weeks, and all participants will receive a "core" treatment consisting of self-monitoring weight, food intake, and steps (all via digital tools provided by the study team), along with behavioral lessons, action plans, and tailored feedback. Depending on which group participants are assigned to in the study, individuals will receive either a more or less challenging goal across the four domains. All study tasks will occur remotely, thus, participants will never come in-person for any tasks. Assessment of body weight and other measures will occur at the beginning of the trial ("baseline"), and at 4 weeks and 10 weeks. The investigators will use the Multiphase Optimization Strategy (MOST) framework to identify which of the goal intensity levels result in meaningful engagement and weight loss. The current study is the first step towards answering this question; it is designed as a pilot factorial trial, which focuses on feasibility and acceptability. In total, there will be 16 treatment conditions.
In this clinical trial, the investigators aim to examine the impact of a 12-week early time-restricted carbohydrate consumption diet on weight loss and glucose metabolism in patients with overweight/obesity and type 2 diabetes
