Episode 80. LIGHT: The New Psychology of Weight Loss | Lizzie Merritt

It’s always a pleasure to sit down with a friend, and this episode is exactly that. I had the chance to talk with Lizzie Merritt, who co-directs the Todd Durkin IMPACT Life Coaching Certification with me. She recently released her second bestselling book, LIGHT: The New Psychology of Weight Loss, and we talk about the book along with the deeper work behind it.

Lizzie is a weight loss coach who has spent years studying the psychology behind lasting change. In LIGHT, she offers a new way to approach weight loss by helping you rebuild self-trust and work with your brain instead of fighting it.

With a mix of warmth, humor, and research-backed insight, Lizzie shares her L.I.G.H.T. Method, a practical framework to shift your mindset and move past the patterns that keep you stuck.

In this episode, you’ll learn how to:

  • Let go of guilt and focus on what actually works
  • Work through challenges like perfectionism, emotional eating, and self-sabotage
  • Use simple experiments to build momentum
  • Stop postponing happiness and start living your life now

This is not a typical diet conversation, and Lizzie is not a typical coach. She brings a grounded, honest approach that helps you get back on your own side.
