Evaluation of a Nutritional Intervention With Dietary Supplements in People Who Have Recently Lost Weight: Effects on Body Composition, Emotional Health, and Gut Microbiota

This study aims to evaluate the effects of a 12-week nutritional intervention with dietary supplements on individuals who have experienced significant weight loss following the use of GLP-1 receptor agonists or similar weight-loss treatments. The study will investigate whether the combined supplementation protocol can improve body composition, emotional well-being, and gut microbiota diversity after discontinuation of pharmacological treatment. Participants will be randomly assigned to one of two groups: an intervention group receiving a daily combination of food supplements containing bioactive compounds (including polyphenols and antioxidants) and a placebo group. Both groups will maintain their habitual diet and lifestyle throughout the study. Primary outcomes include changes in fat-free mass, emotional state, and gut microbiota composition. Secondary outcomes include metabolic markers, appetite regulation, and quality of life indicators. This project seeks to provide evidence-based strategies for maintaining health and preventing metabolic rebound following rapid weight loss or pharmacologically induced appetite suppression.

Physiologic Response to Bariatric Surgery and the Impact of Adjunct Semaglutide in Adolescents

The study plans to learn more about what happens to the body after bariatric surgery in people 12 to 24 years old. The study aims to understand why people respond differently to bariatric surgery and how to define success beyond weight loss alone. The study also plans to learn more about whether a medication (semaglutide or tirzepatide) can help people 12 to 24 years old who, between 6 and 24 months after bariatric surgery, have not lost as much weight as expected.
