Active clinical trials for "Obesity"

Very low carbohydrate diets and high-complex carbohydrate, low-fat diets are popular weight-loss methods in the United States. The purpose of the Energy Balance Study is to explore how extreme differences in diet affect eating behaviors, activity and calorie-use, and body composition. We will conduct a controlled feeding study (all food will be provided for the duration of the study) in which obese adults will be randomly assigned to one of three dietary groups: a low-carbohydrate-eat as much as you like diet, a high-carbohydrate-eat as much as you like diet, or a high-carbohydrate-calorie-restricted diet. The low-carbohydrate diet will be modeled after the Induction Phase of the Atkins Diet. The high carbohydrate diet will be based on the "Dietary Approaches to Stop Hypertension (DASH)" diet. During the first 3 weeks, participants will eat a typical diet adjusted so that they neither gain or lose weight. Then, for 6 weeks, they will eat their assigned research diet. Resting calorie use and body composition measurements will be taken at the end of week 2 and week 9. Frequent blood sampling for 24 hours will be done through a catheter (tube) placed in an arm vein at the end of weeks 2 and week 9 and for 12 hours at the end of week 3. Change in body composition, activity and energy expenditure, and blood components known to influence eating behavior will be measured under typical diet conditions and after one-day and 6 weeks of the research diet.

The investigators ultimate goal is to test the hypothesis that immediate feedback of dietary adherence will enhance compliance to a weight loss program. This study deals directly with gathering the needed preliminary data for a grant submission.

The PILI 'Ohana CBPR partnership implemented a pilot study to determine whether a Family plus Community focused intervention will improve weight loss maintenance compared to Standard follow-up in overweight/obese Native Hawaiian (NH) and other Pacific People (PP) adults (> 18 yr. old) after receiving a standard individual-focused behavioral intervention. The primary hypothesis was that overweight/obese NH and PP adults that undergo a combined family-focused plus community-focused intervention vs. a standard follow-up after receiving a standard individual-focused behavioral intervention will have significantly higher rates of weight loss maintenance.

The purpose of this study is to determine if chewing gum increases energy expenditure and decreases food intake.

The aim of this prospective randomized study is the prevention of excessive weight gain in obese pregnant women. The study will compare perinatal outcomes of obese pregnant women treated in the traditional way to outcomes of nutritionally monitored obese pregnant women and evaluate a preliminary behavioral model applicable to the general practice of obstetrics.

to compare the results of SASI to SAS-J in treatment of morbid obesity

In this study, the investigators evaluated the association between various measures of adiposity [BMI and waist circumference (WC)] and clinical outcomes in Asian patients with AF who were prescribed OAC, using a nationwide population based cohort.

This study tests if semaglutide tablets of 50 mg can help people with obesity to lower their food intake compared to placebo. This study also tests how semaglutide 50 mg works on appetite, control of eating (such as cravings and restraints) and how long time the food stays in the stomach after a meal. In addition, how much semaglutide is in the blood will also be tested. Participants will either get semaglutide or placebo - which treatment participants will get is decided by chance. Participants will receive one semaglutide (or placebo) tablet per day during the 20-week treatment period. The dose of semaglutide is slowly increased every 4 weeks during the study to reach the treatment dose of 50 mg semaglutide taken for 4 weeks. The study lasts for up to 29 weeks for each person and includes a screening period (up to 4 weeks), a treatment period (20 weeks) and a follow-up period (total of 5 weeks after the last dosing). Participants will have 12 visits with the study doctors at the institute.

Gardner GOALS is a 6 month program for treatment of childhood obesity that consists of twice monthly telehealth meetings with a health educator. Potential participants enter the study using a randomly ordered list of eligible patients based on BMI, age and number of clinic visits in 2020.

This study will test whether managing the hours during which people eat, called time restricted eating, might help them to lose weight. For this study, one parent and a child will enroll as a group (called a dyad). The dyads will be assigned at random to practice time restricted eating (within 10-12 hours per day) but will be able to eat whatever they would like or to limit portion size and increase fruit, vegetable and lean protein intake and limit sugar sweetened beverages and undergo . Both groups will receive dietary counseling, Bluetooth toothbrushes and scales to help monitor their progress. The study will last for 12 weeks and will have one survey four weeks after the last in person visit. There will be 2 in person visits, 7 virtual visits, 2 phone visits and daily time logs.
