Show Notes

In this episode of The Dana Parish Podcast, I sit down with one of TIME100's Most Influential Health leaders, Dr. Ziyad Al-Aly. He's a renowned nephrologist/ epidemiologist & researcher at Wash U, and today we dive into his groundbreaking new GLP-1 study, published in NATURE, where unexpected benefits and side effects were discovered.

This is the largest GLP-1 study to date, encompassing over 215,000 patients, 4 years, and 2 million controls. We cover:

  • How GLP-1 medications work: mechanisms affecting weight loss, inflammation, and neurocognitive health.

  • Unexpected benefits: Reduced risks of Alzheimer's, substance use disorders, seizures, and infectious diseases.

  • Side effects & controversies: GI issues like gastroparesis, pancreatitis, need for longer-term study, and the debate over dependency.

  • Micro-dosing: The dose makes the poison

  • Multisystemic Benefits: A possible treatment for Long Covid?

  • Obesity: The Mother of All Ills

  • America is SO Unhealthy: The role of ultra-processed food and how GLP-1s could transform public health.

  • The affordability crisis: Why high costs and limited access are preventing widespread benefits.

Dr. Al-Aly doesn't shy away from discussing the polarizing nature of GLP-1 medications, and addresses the controversies and concerns surrounding these drugs.

Don't miss this fascinating discussion that could reshape how we handle chronic disease treatment and prevention.
