Dietary Protein Sources and Glycemic Variability

This goal of trial is to evaluate the effects of plant-based vs. animal-based diets on glycemic variability in overweight or obese adults through a 3-week dietary intervention. The main question it aims to answer is: Will a plant-based diet be able to reduce glycemic variability in overweight or obese adults compared with an animal-based diet? Participants will strictly follow a designated plant-based or animal-based dietary regimen throughout the duration of the 3-week study. They will wear a Continuous Glucose Monitor (CGM) throughout the study, engage in weekly clinical assessments, and record their daily dietary intake.
