In this episode of The Holistic GLP-1 Podcast, we welcome world-renowned physician, bestselling author, and founder of NutritionFacts.org, Dr. Michael Greger. 

Known for his evidence-based, straight-shooting approach to nutrition and lifestyle medicine, Dr. Greger provides a clear look at the most pressing questions surrounding GLP-1 medications, their promises and pitfalls in a 2025 context and beyond.

Key topics here include: the truth about food noise, the metabolic downsides of artificial sweeteners, and the very real concern of disproportionate lean muscle loss while taking these drugs.

We also consider how natural foods and spices like turmeric, cinnamon and even vinegar can naturally stimulate GLP-1 in the body, and why strength training may be your single most important ally to protect your health while taking these medications.

If you’ve ever wondered whether GLP-1s can be a bridge to better habits—or just a prescription for a lifelong pharmaceutical plan—you won’t want to miss this refreshingly direct conversation with Dr. Michael Greger.

So, without furthers ado, let’s get into it!
