42. Colleen Cutcliffe: Why Your Gut Holds the Key to Metabolic Health (And How to Fix It)

Have you ever wondered why gut health is at the root of everything, from metabolism and cravings to immunity and even mental clarity? Why do some people struggle with weight gain, energy crashes, and digestive issues despite eating well? And could the rise of GLP-1 medications like Ozempic be a sign that we've been ignoring a natural solution all along? In today's episode of Extend, I'm joined by Colleen Cutcliffe, a microbiome scientist and co-founder of Pendulum, a company leading the way in gut health research. She's here to break down why your microbiome isn't just about digestion, it plays a critical role in weight regulation, blood sugar balance, and even hormone production. We'll explore how your gut bacteria influence GLP-1, the hormone behind popular weight loss drugs, and why restoring your microbiome may be the key to naturally optimizing metabolism, reducing cravings, and improving long-term health. If you've ever dealt with stubborn weight, gut issues, or unexplained fatigue, this episode will give you science-backed strategies to rebuild your gut health, support natural GLP-1 production, and take control of your metabolism, without relying on injections. Colleen Cutcliffe, PhD, is a biochemist and microbiome researcher with over 20 years of experience in biotechnology and life sciences. She is the CEO and co-founder of Pendulum, a company pioneering next-generation probiotics to optimize metabolic and gut health.
