The Hidden Heart Benefits of GLP-1s (with Dr. Ralph DeFronzo)

In this breakthrough episode, Dr. Ralph DeFronzo—one of the most respected names in metabolic health—joins Elizabeth to discuss the real story behind GLP-1 medications.

If you've ever wondered:

Do I have to stay on GLP-1s forever?

Are lower doses (or "microdoses") actually effective?

Can I activate GLP-1 naturally—without prescriptions?

Is it really safe for long-term use?

…this episode gives you honest answers, straight from an expert who helped define modern diabetes treatment.

Dr. D explains how GLP-1s not only facilitate weight loss by reducing one's appetite, but also protect your heart, liver, brain and kidneys—and why most people overlook this crucial benefit. You'll learn what makes someone a "super responder," the link between cortisol and weight loss resistance, and how to finally quiet "Food Noise" for good. ✨
