Attrition from pediatric weight management programs is unacceptably high, with dropout ranging from 27-73%. This project will utilize a model that predicts dropout from treatment, increasing its power and accuracy through a multi-site observational study. This will result in a powerful tool that will be used to decrease attrition from pediatric weight management, with the potential for widespread dissemination to improve treatment outcomes.

The effectiveness of low-protein diets supplemented with essential aminoacid (EAA) formulas in genetic disorders of amino acid (AA) catabolism, such as maple syrup urine disease (MSUD), is widely recognized (Blackburn PR et al. 2017). The main aim of the present study is to evaluate a difference in the effectiveness of a multidisciplinary rehabilitation program in patients with high degree of obesity with and without supplementation of this new formula of amino acids (essential + tricarboxylic acids - EAA-AC). For this reason, patients of both sexes, aged between 45 and 65, suffering from high-grade obesity will be recruited in Piancavallo. The enrolled patients divided, randomly, into two groups will be given: EAA-AC group a low-calorie and low-protein diet integrated with 4 sachets of EAA-AC supplement per day; the control group will follow a low-calorie and low-protein diet only with placebo. The parameters considered, after two weeks of treatment, will be: weight loss; the maintenance/recovery of muscle mass assessed through changes in body composition and functional tests (Hand grip, 6MWT or TUG) but also through the analysis of mitochondrial function in PBMC and circulating levels of mtDNA; the improvement of the glucose picture and the lipid profile. 1 month after discharge, patients will carry out an outpatient check-up to evaluate the maintenance of muscle mass using impedance testing.
NCT04036331
The purpose of this research is to determine the effectiveness of a coordinated program (Dyad Plus) that would help to facilitate self-monitoring, positive communication, joint problem solving, and social support to increase physical activity, healthy eating, and weight loss. Participants of the Brenner FIT (Families In Training) pediatric weight management program and their parent/guardian will co-enroll in weight loss programs. Parents/guardians will receive the components of By Design Essentials.
NCT00739362
This study will determine whether electrical stimulation of an area of the brain called the dorsolateral prefrontal cortex, which is important in determining the feeling of fullness after eating, affects how much food a person eats and weight loss over 4 weeks. It will also compare weight changes in people who attend weight loss counseling sessions and those who do not over this period of time. Obese, non-diabetic people between 18 and 60 years of age who are in good health and who live in the Phoenix, AZ, metropolitan area are eligible for this study. Candidates must have a body mass index of 35 kg/m(2) or more and weigh less than 350 pounds. Participants are admitted to the NIH inpatient unit in Phoenix for the first 9 days of the study for tests, which include meal tests to determine eating behaviors and caloric intake, blood and urine tests, glucose tolerance test, weight measurement, psychological assessments and DEXA scan to measure body fat. For 3 of the days, they will be asked to eat all of their food from automated vending machines. Some subjects receive transcranial direct current stimulation (TDCS). For this procedure, electrodes that conduct electricity are placed on the head and arm and the current is turned on for 40 minutes. Some tingling may be felt under the electrodes. Other subjects receive sham TDCS, with the current turned on only very briefly. After the evaluations, subjects are discharged home from the NIH unit and instructed to eat 25 percent fewer calories than they consumed while on a weight maintenance diet the first 3 days of their inpatient stay. They maintain the lower calorie diet at home for 4 weeks. During this period they come to the NIH unit 3 days a week to receive either real or sham TDCS.
NCT00687115
This study will investigate how to better predict why some individuals gain or lose weight more easily than others. It will examine whether the increase in the amount of energy a body burns in 24 hours with overeating or the decrease over 24 hours with fasting can help determine how easily someone gains or loses weight. Healthy people between 18 and 60 years of age who have a body mass index (BMI) between 18.5 kg/m(2) and 24 kg/m(2) (for overfeeding study) or a BMI greater than 27 kg/m(2) with a body weight less than 350 pounds (weight loss study) may be eligible for this study. The study requires a 10-week admission to the NIH Clinical Center (2-week baseline, 6-week overfeeding/weight loss, 2-week post-weight change). Participants undergo the following tests and procedures during the hospital admission: * Medical history, physical examination and laboratory studies * Questionnaires to assess eating behavior, food preferences, body composition, and activity level * Body composition assessment (height, weight, waist circumference, and fat mass and muscle content through DXA and MRI scans) * Oral glucose tolerance test * Meal test to measure the response of certain hormones to food * Activity monitors to determine activity level * Metabolic chamber study to measure calories burned over 24 hours and monitor body temperature * Free-living energy use study to measure calories burned under normal home conditions over 7 days * Fat and muscle biopsies * Dietary intervention: Measurements of food intake and energy loss over a 6-week overfeeding (1.5 times the subject s normal food intake) or weight loss (one-half the subject s normal food intake) program Followup procedures after the inpatient stay: * Height and weight measurements at 6 months (overfeeding study participants) and monthly for the first year, at 3-month intervals for the second year, and then yearly for 3 more years (weight loss study participants) * Yearly visits (2-night inpatient stay) for all participants for repeat meal test, DXA, oral glucose tolerance test, behavioral questionnaires and, in women who can become pregnant, pregnancy test
NCT06989203
This study is a randomized clinical trail with a parallel design, involving 120 overweight/obese (body-mass index, BMI ≥ 24 kg/m²) participants and 20 normal-weight participants. Overweight/obese participants will be randomly allocated to one of three groups: 1) calorie restricted balanced diet (CRD)group; 2) CRD + semaglutide group; or 3) CRD + segaglutide with protein supplementation. Through a 3-month weight loss intervention and 6-month follow-up, this study aims to investigate the effects of dietary protein supplementation combined with semaglutide on weight loss, energy and glucose and lipid metabolism, muscle loss, and weight regain. Additionally, the study will explore key factors affecting intervention efficacy, including obesity phenotypes, gut microbiota profiles, genetic backgrounds, and lifestyle factors, to provide evidence for optimizing individualized intervention strategies.

The goal of this clinical trial is to identify the specific characteristics (phenotypes) that may be useful to help select the right medication for weight loss, and to study the effect of individualized guided medication in patients with bipolar disorder ages 18-65. The main questions it aims to answer are: * Can the investigators compare the distribution of obesity characteristics (hungry brain, hungry gut, emotional hunger) between bipolar patients and non-bipolar participants (comparing from IRB #24-002375)? * Can the investigators evaluate the feasibility of anti-obesity medication (AOM) in patients with bipolar disorder? Participation will last for about 20 weeks and includes 8 in-person study visits, up to 11 phone call visits, and 13 virtual group therapy sessions. The first visit lasts about 2 hours and includes going over the informed consent form, a diagnostic interview to confirm diagnosis, gathering vital signs, mood questionnaires, an ECG, a blood draw, and urine drug and pregnancy tests (if applicable). The second visit lasts about 6-7 hours and involves multiple procedures and completing questionnaires to determine which study drug would allow participants to lose weight most effectively. At the third visit, participants will be assigned to take one of three FDA approved medications for weight loss: Semaglutide (Wegovy®), Naltrexone/Bupropion (Contrave®), or Phentermine/Topiramate (Qsymia®). It is possible that participants could be assigned to a group that receives no study medication. All participants will be enrolled in a 12-week virtual group therapy program targeted for weight loss. On this third visit the investigators will also gather vital signs, and participants will give a sample of blood. After the third visit, participants will come in for study visits every 4 weeks for 20 weeks (5 visits) to assess medication adherence, vitals, and answer questions about mood and eating (participants will also give a sample of blood at the 8-week and 20-week visits). For participants assigned to a study medication, the study team will call every week for the first 2 months (excluding in-person visit weeks) to assess mood and safety. After the first 2 months, the study team will call the participant every two weeks in between in-person visits. Participants will be compensated for time spent in this study. Participants assigned to a study medication will also be given the option to participate in the open-label phase of the study, which involves 3 follow-up visits (weeks 24, 36, and 48) over 7 months after the 20-week trial. During this phase, participants can continue to take the medication through their clinical care provider.
NCT07032571
The goal of the Reset trial is to learn about the optimal combination of dietary behavior strategies in a fully digital weight loss intervention. The intervention is designed for adults with overweight or obesity. The investigators will examine the impact on weight loss of four dietary strategies: 1) limiting Red Zone Foods (i.e., foods that are high in calories and low in nutrition), 2) limiting eating windows, 3) increasing protein intake, and 4) increasing fiber intake. Each of these strategies will include goal setting, daily self-monitoring, and tailored feedback. The investigators will recruit 208 participants. Broadly, adults with overweight or obesity who live in the U.S. will be eligible. The weight loss intervention will last 12 weeks. All participants will be asked to track their body weight daily and complete weekly behavioral lessons and action plans to promote healthy eating and physical activity. All study tasks will occur remotely. Assessment of body weight and survey measures will occur at the beginning of the trial ("baseline"), and at 1 month and 3 months. The Multiphase Optimization Strategy (MOST) framework will be used to identify which combination of the dietary behavior strategies results in the greatest weight loss. In total, there will be 16 treatment conditions.
NCT07280403
The goal of this clinical trial is to determine the effect of a low carbohydrate higher protein diet, modelled after the Atkins program on weight loss, glycemic control, risk markers of cardiovascular disease and body composition in patients taking semaglutide. Participants will: * Be randomized to follow either a low carb, higher protein diet or a low fat diet for 3 months. * Visit the clinic at week 2, 4, 8 and 12 to meet with a dietician, fill out a symptoms questionnaire and for bloodwork * Complete 3-day food records 4 times over the 12 weeks.

This project anticipates addressing the obesity epidemics problem which has caused unhealthy lifestyle in billions of obesities and overweight people worldwide. The investigators propose on digital health solution in providing healthcare-on-demand, for personalized health, healthy lifestyle and weight management. This study proposes on using Cognitive Behavior Therapy (CBT) in decreasing individual's food craving, which is administered through AI (Assistive Intelligence) tracking. As with any new medicine, uncertain long-term effects and high costs of these new drugs are also critical factors considered by physicians and policy makers worldwide. Researchers have also reported on 85% of people re-gaining premedication weight after 5 years. There is no easily available self-controlled monitoring strategy/intervention for the unhealthy lifestyle is believed to be one of the main problems. Therefore, the investigators propose on the research and development of self-managing digital health APP (application) for 12 months over two phases, with three months to design APP and nine months to confirm the clinical validation. During the first phase, the investigators propose on design of an "AI Mindful Eating" App, to enhance individual's healthy lifestyle with subsequent weight-loss. Based on "gut-brain-axis", this is anticipated to be achieved by using CBT and AI is used to recognize nutrition and mood within mobile images. This facilitates fulfilling lifestyle and long-term weight-loss. Finally, the study proposes to complete function definition and clinical validation for our AI Humanity APP. By scheduled check-up program by monitoring and analyzing body weight, body fat, anthropometric and metabolic change data between case and control groups. The investigators intend to disclose the effect of the AI assistant APP in weight management and metabolic disease prevention.

NCT06811324
Obesity and type 2 diabetes mellitus (T2DM) represent major public health concerns in the aging community. Tirzepatide, a novel dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist recently approved for the treatment of T2DM and obesity has been shown to be effective at reducing weight, improving markers of T2DM control, and improving cardiovascular health. Utilization of tirzepatide among older adults has been on the rise since FDA approval was issued, however the effects of tirzepatide use on functional outcomes in older adults with obesity are not well established. Recent studies show that weight loss caused by tirzepatide may be driven by substantial loss of lean muscle mass, which may contribute to weakness and frailty, particularly among older adults. The proposed pilot study aims to evaluate how treatment with tirzepatide for 6 months affects muscle mass and function among older adults, and if changes in muscle mass are linked to changes in functional status over the same time period.
