Fiber is suddenly showing up everywhere, from soda and candy to pasta and protein snacks. But more fiber isn’t automatically better, especially when it leaves you feeling bloated, uncomfortable, or confused about what your body actually needs.
Registered dietitian and GLP-1 user Ana Reisdorf sits down with David Istier, founder and CEO of gutzy Organic, to discuss the gut microbiome, prebiotics, probiotics, and why different sources of fiber can feel different in your body. David also shares how his experience helping launch GoGo squeeZ in the United States—and the health challenges he faced while building his own company—led to the creation of gutzy.
For people taking GLP-1 medications, the central takeaway is simple: eating less makes the nutritional quality of what you eat even more important. Ana and David discuss how to look beyond protein and fiber marketing claims, prioritize real food, and find convenient options for days when appetite is low.

**ABOUT THE GUEST**
David Istier is the founder and CEO of gutzy Organic. Originally from France, David began his career in food marketing and later helped launch GoGo squeeZ in the United States. After experiencing significant stress and health challenges while building his own company, he became interested in plants, prebiotic fiber, and gut health. That experience eventually led him to create gutzy Organic and its refrigerated fruit-and-vegetable pouches.
