Filter by:With this trial, the aim is to assess the benefits and harms of a non-surgical intensive weight loss intervention that includes total dietary replacements, behavioural support and weight-loss medication compared with bariatric surgery for people with severe and complex obesity. The interpretation of the results will help inform future care pathways for people with obesity in whom bariatric surgery is currently the only available effective treatment option.
Calorie restriction (CR) is the most important treatment for weighting loss. In recent years, two novel types of intermittent fasting recently have gained more attention: the 5:2 diet and time-restricted eating (TRE). TRE requires individuals to eat in a specified number of hours per day (typically 4 to 10 hours) without energy intake restriction. The 5:2 diet involves 5 feast days and 2 fast days per week; participants eat ad libitum without restriction on feast days while 25% of energy needs (approximately 500-800 kcal per day) are consumed on fast days. However, the effects of dietary strategy of intermittent fasting plus time-restricted eating (modified time-restricted eating: TRE 5 days and fasting 2days per week) on weight loss and cardiometabolic risk factors in obese adults have not been proved. This randomized controlled trial aimed to evaluate the effect of modified time-restricted eating (mTRE) and CR on weight loss and cardiometabolic risk factors in obese adults compared to usual health care over 12 months.
The Investigators propose suture plication placement at the distal gastric body drives a significant portion of weight loss in endoscopic sleeve and sutures only need to be placed in the distal gastric body. Therefore, in this pilot study, the investigators aim to compare "belt" with "belt and suspenders" plication pattern using the Endomina system to determine percent total weight loss.
The purpose is to optimize the EMPOWER program by integrating strategies to reduce food cravings, a critical yet often overlooked factor for long-term success in weight management. The objective of this study is to determine the efficacy of craving coping strategies on weight loss outcomes by conducting a randomized controlled trial. Participants will be randomized to receive one of the two strategies to manage food cravings.
The purpose of the Chinese Obesity and MEtabolic Surgery Database (COMES Database) is to collect data and examine the long-term effects of metabolic and bariatric surgery on obesity and metabolic disorders in the Chinese population.
The purpose of this study is to evaluate if and how continuous glucose monitors (CGMs) impact food consumption, choice, and purchasing in individuals attempting to lose weight using their own weight management approach.
The goal of this randomized control trial is to compare the effect of a liquid formula rich in nutrients and low in calories (supplement) with the progressive diet with conventional foods that we usually recommend in patients after surgery. The main question it aims to answer is if the addition of a high-protein, volume-controlled nutritional supplement as a fundamental part of the diet during the first two months after surgery will preserve the patient's nutritional status and prevent the appearance of nutritional deficits and associated complications. Participants will be evaluated at the beginning, at 1 month and at the end of the study (2m) and the following determinations will be made: - Analytical determination - Nitrogen balance by determining urea N2 in 24-hour urine - Anthropometric determinations - Body composition determined by impedanciometry - Resting energy expenditure and nutrient oxidation measured by indirect calorimetry. - Energy, protein and hydration intake. - Gastrointestinal tolerance through self-registration of symptoms. Researchers will compare the effect of a complete hypocaloric liquid formula group with the usual progressive diet group to see if they achieve the protein intake goal established for patients after obesity surgery, preservation of nutritional status and lean mass during the rapid phase of weight loss and the gastrointestinal tolerance during the first two months after surgery.
Prolonged dietary protein restriction has been shown to increase energy expenditure in mice simultaneously with an increase in plasma FGF21 levels. In overfeeding studies, a protein-restricted diet reduces weight gain in both mice and humans compared with normal and high-protein diets. Further, in energy balance studies, when lean men are provided with a protein-restricted diet for five weeks, an increase in energy intake was necessary to obtain their body weight. However, whether the effect of a protein-restricted diet is the same when consumed by overweight to obese men has divergent results in both mice and humans.
Reliability of Chest Wall Perforator Flaps for Breast Reshaping following Massive Weight Loss
This study is a parallel randomized controlled trial (RCT). To determine the effect of intermittent fasting, intermittent fasting with behavioral economics, and intensive lifestyle modification on nutritional status; the differences between HOMA-IR, body weight change, and body composition in obese people. Each participant will be randomized to receive the intervention (intermittent fasting, intermittent fasting with behavioral economics, or intensive lifestyle modification. The study protocol will be explained to the eligible participant and informed written consent will be obtained. The total sample size will be 123 participants. Blood and urine samples will be collected at baseline and each follow-up visit including 1-month, 2-months, 6-month, and 12-months, respectively for further study to find out the mechanisms of weight loss, weight regain, and the improvement in the metabolic disease.
