HealthHealth & FitnessFitness
GLP-1 receptor agonists have transformed weight loss and metabolic health—but what are we overlooking? In this episode of New Frontiers in Functional Medicine, Dr. Kara Fitzgerald is joined by Dr. Sanjay Bhojraj and Dr. Alexis Gonzales to explore the clinical tradeoffs of GLP-1 therapy, including lean muscle preservation, nutrient status, weight regain, and long-term metabolic health.

The conversation also examines SiPore, an engineered silica-based intervention that works locally in the GI tract to slow the breakdown and absorption of carbohydrates and fats. Dr. Fitzgerald and her guests discuss findings from the randomized, double-blind, placebo-controlled SHINE trial, including outcomes related to A1c, visceral fat, waist circumference, cholesterol, and lean mass.

They also explore how CGMs can reveal post-meal glucose patterns, why muscle preservation matters during weight loss, and how clinicians can support patients transitioning off GLP-1 medications—including those preparing for pregnancy, IVF, or surgery.
