Fiber as GLP-1 Booster: Experts Weigh In
A Vogue article examines whether fiber can boost the effects of GLP-1 drugs like Ozempic. Experts including Dr. Stephanie Behringer-Massera of Mount Sinai and Dr. James Alexander Joseph of CeliaRx explain that fiber may activate gut receptors to release natural GLP-1, but effects are short-lived. While 95% of the US population lacks sufficient fiber, it is not a proven booster for GLP-1s. Both protein and fiber are essential: protein supports muscle and tissue repair, fiber supports gut health and metabolism. Adults should aim for 25–38 grams of fiber daily from whole foods like lentils, beans, chia seeds, and leafy greens. Supplements like Metamucil offer only one fiber type; a diverse diet is better for gut microbiome. Rapid increase in fiber can cause bloating and cramping; gradual introduction with hydration is recommended.
