641: Understanding Fiber and Gut Health with Dr. Will Bulsiewicz

Age Less / Live More

Fiber is often overlooked in discussions about diet, weight loss, and immunity, but it shouldn’t be. Fiber is essential for digestive health, improving gut motility, and regulating bowel movements. It’s also key for weight management, as high-fiber foods are more filling. Research shows that fiber can reduce LDL cholesterol, potentially lowering the risk of heart disease. Additionally, fiber lowers the glycemic load of foods, helping prevent metabolic syndrome and related conditions. Fiber also plays a crucial role in microbiome health, acting as a prebiotic to support the growth of beneficial gut bacteria, which positively impacts immune function, mental health, and more. The issue? Most of us don’t eat enough fiber or a wide variety of plants. My guest on this podcast is a gastroenterologist who literally wrote the book on fiber and will share his insights on how to heal your gut.

Listen and learn:

• About fiber, resistant starch and polyphenols as prebiotics
• Why you should aim to eat 30 plant foods weekly
• The importance of colorful plant foods
• How fiber transforms into antiinflammatory short chain fats in your gut
• The reward vs. risks of fecal transplants
