Effect of a High-Protein Diet With Meal Replacements on Weight Loss

The goal of this clinical trial is to learn if a structured high-protein diet with meal replacements can help with weight loss in adults with overweight or obesity. The main questions it aims to answer are: Does this diet help participants lose more body weight? Does this diet improve body composition and blood markers such as glucose and cholesterol? Researchers will compare a structured diet program with meal replacements to a standard low-calorie diet to see if it leads to better weight loss and health outcomes. Participants will: Follow a calorie-restricted diet for the duration of the study Be assigned to either a meal replacement program or a standard diet Attend study visits for body measurements and blood tests Report their feelings of hunger and fullness
