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

From the registry

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…
