Active clinical trials for "Weight Loss"

This weight loss study will investigate the impact of calorie distribution across a day (large breakfast meals and smaller evening meals versus small breakfast meals and large evening meals) on body weight, and physiological and behavioral mechanisms regulating energy balance. Participants will undergo 2 x 4 week energy restriction protocols in a randomized cross over design; big breakfast (45% of calories in the morning meal, 20% at dinner) and big dinner (45% of calories in the evening meal, 20% at breakfast). We predict that timing of eating will influence energy balance, because morning energy expenditure is amplified in comparison to the evening. This study will allow us to assess whether the increased energy expenditure in the morning is linked to natural biological circadian rhythm or behavioral adaptions.

The purpose of this study is to evaluate the efficacy of cryotherapy on the slimming of subcutaneous fat mass in the abdomen and saddlebags. Cryotherapy is a completely non-invasive method that induces a selective reduction of fat cells by localized and controlled cooling in areas such as the abdomen, flanks, inner knees, inner thighs, back and arms. Adipose tissue is composed of two types of tissue: white and brown adipose tissue. Studies have shown that exposure to cold induces an increase in the number of brown adipocytes (detected by PET/CT-scan) under the effect of the hormone irisin produced by the muscles. In addition, another study has shown that prolonged exposure to cold reduces the size of brown adipocytes leading to thermogenesis, suggesting that cold exposure may contribute to the control of obesity. The freezing technology of this cryotherapy unit allows the temperature of the subcutaneous adipose tissue to move almost instantaneously from -6°C to -10°C, gradually causing the reduction of subcutaneous adipose tissue.

The purpose of this study is to compare the effect of endoscopic sleeve gastroplasty (ESG) with diet and exercise, to diet and exercise alone, to see which is better in weight loss reduction. Investigators will also compare the effects of ESG to diet and exercise comorbidities such as diabetes, sleep apnea and high cholesterol as well as the various obesity related hormones.

This study evaluates different versions of a text messaging-based app for weight loss. This study will place participants to 1 of 32 experimental conditions that reflect different texting components and levels. Participants will be randomized to a condition. The investigators will recruit 448 adults into a 6-month weight loss program, with an additional follow-up 6-months after the intervention ends.

Inclusion Criteria: aged 21 and older, BMI>=25, and presence of recurrent binge eating on the MOVE! Survey. Exclusion Criteria: more than 4 MOVE! sessions in the prior year; active psychosis or suicidal ideation; medical or psychiatric illness, or cognitive deficits that interfere with providing consent or completing assessments, and; pregnancy or lactation. Participants will be recruited from the VA's MOVE! Program at VA Connecticut Healthcare System (both Newington and West Haven campuses). Those participants who meet eligibility and are interested in the study will meet with a research associate who will obtain written consent. A baseline appointment will be made where the participant will complete written assessments, anthropometric measures (weight, height, blood pressure etc.), along with a blood draw. Participants will then be randomized, by luck of a draw, to either MOVE! or MOVE!+clinician-led CBT treatment. For those randomized to the MOVE! condition, participants will continue in the MOVE! program by meeting with the multidisciplinary team in a group setting once a week for 60 minutes, for 16 weeks. The group sessions are lead by a dietician, health psychologist, and physical therapist. For those randomized to the MOVE!+CBT treatments, participants will continue in the MOVE! program as described above, but will also partake in up to 10 individualized sessions over a 3-month period. Participants will be given a treatment manual to read at home, ask to complete daily food logs and work with the study therapist to create goals and complete homework that is geared at examining and changing how participant think about binge eating and how that thinking affects behavior. Lastly, a walking program will also be incorporated into the treatment. For both treatment arms, 3 months from treatment starting, then again at 9 months and 15 months, participants will be asked to complete post and follow up assessments, much like the baseline.

The aim of the trial is to study the effect of a mobile application-based lifestyle change program on body weight loss in adult subjects with obesity. The main focus is to motivate and support beneficial lifestyle changes targeting long-term weight management. This study comprises two randomly assigned study arms: mobile application-based lifestyle change program and "waiting-list" control. The mobile application-based lifestyle change program consists of twice a week content for the first 6 months, continuing with less frequent contents for the following 6 months (the length of intervention 12 months). The "waiting-list" control group will receive mobile application-based lifestyle change program after 6 months followed by intervention for 12 months. The main aim is to demonstrate that the users of mobile application-based lifestyle change program lose more weight than controls at 6 month timepoint and weight loss is maintained for 18 months (6 months after the end of mobile application-based lifestyle change program use). Weight is measured and blood samples (lipids, glucose and metabolic syndrome measures) are collected at 0, 6, 12, and 18 months. The mobile application-based counselling contains aspects of cognitive behavior therapy and persuasive system design and consists of twice a week reminders, tasks, self-monitoring, and reflection. The main outcome is the decrease in body weight. Secondary outcomes are changes in eating behavior, psychological factors, components of metabolic syndrome (waist circumference, plasma lipid and glucose values, blood pressure), and calculated scores of metabolic condition and adiposity.

With the prevalence of obesity soaring and the absence of an effective and safe treatment that is low-cost and always feasible, the use of food supplements has gained attention for the potential benefits in the absence of significant safety concerns. Cinnamon (CC) and Withania somnifera (WS) are plant-based supplements reported to be effective in improving metabolic health and body composition, the first mainly acting on insulin resistance and the second on energy expenditure and leptin resistance, as shown in preclinical and some clinical studies. Their association, possibly synergistic leveraging different mechanisms of action, has never been studied. This was a double-blind placebo-controlled study. Patients with overweight or obesity were prescribed a mildly hypocaloric diet with CC 300 mg plus WS 150 mg tid for 4 weeks in a cross over design and anthropometric parameters together with safety outcomes were collected.

The purpose of this study is to assess the effect of a food-specific Go/No-Go (GNG) computerized training task on weight loss, food evaluation, and disinhibition in a population of overweight and obese individuals.

This study will investigate the acute effect of three isocaloric meals varying in level of food processing, including a whole foods, gluten-free, and highly processed meal on energy metabolism and blood glucose in 8-12 young adult, normal weight females. A secondary aim of this proposed study is to compare palatability, satiety, and perceived energy ratings among highly processed, unrefined, and gluten-free unrefined isocaloric meals.

Abstract Introduction: This pilot study will determine the recruitment feasibility, retention, and adhesion for a motivational interviewing program for weight loss in adults according to the processes of change in weight loss. Methods and Analysis: The single-arm pilot study will be a feasibility study of the Motivation to Lose Weight version 1 (MLW v.1). The study includes presential and online sessions. Participants will be recruited through advertisements on social media and selected according to the inclusion criteria. Participants will receive 8 sessions of approximately 30-45 minutes of motivational interviewing (MI) according to the processes of change in weight loss, as measured by the S-Weight scale. The results will be evaluated at the beginning and the end of the program, which will last 8 weeks. The primary outcome of the study is feasibility. The intervention will be feasible if adherence to the proposed activities in the sessions is greater than 70%, we can recruit 10 patients within 8 weeks, the proportion of interested people and registered participants is greater than 30%, and more than 75% of participants attend the final study visit. The secondary outcome is weight loss, fat mass percentage, muscle mass, waist and hip measurements, and the scores of behavioral scales. Ethics and discussion: The feasibility of this project consists of proposing an individualized intervention based on MI strategy(s) for each participant, according to the stage of readiness, and thus, help to evolve in the process of losing weight. This intervention aims to increase the participant's confidence level to implement actions that lead to the progression of behavior and, consequently, the action and maintenance of the lost weight. This study was approved by the Research Ethics Committee (REC) of the Hospital de Clínicas de Porto Alegre (HCPA) under number 20220209 CAAE 59573622300005327.
