In this episode, we dive into a recent study led by Dr. Carla Prado published in Lancet Diabetes & Endocrinology, which explores the impact of GLP-1 receptor agonists on muscle loss during weight loss treatments. These medications are widely used for their effectiveness in reducing body weight, but Prado’s research highlights an important concern: the significant loss of lean mass, including muscle, which can make up as much as 39% of the total weight lost with GLP-1 agonists. This rate is notably higher than that seen with non-pharmacological weight loss, where muscle loss is typically 10-30%.

Why does muscle loss matter in weight loss? Muscle is essential not only for strength and movement but also for regulating blood sugar, supporting immune function, and storing amino acids needed for recovery and health. Losing muscle mas ...
