In this episode, Kayla sits down with Dr. Karan Rajan, who is one of the most followed medical professionals on social media, and he breaks down the gut microbiome like you've never heard before. If you've ever felt bloated after eating fiber, tried keto and felt amazing temporarily, or wondered why your "clean" diet isn't delivering results, this episode is for you.
They talk about why fiber is non-negotiable fuel for your gut bacteria, how to gradually increase intake from 10g to 50g+ daily, and the specific prebiotic fibers that matter most. Dr. Rajan shares his daily eating protocol, explains why prebiotics trump probiotics, and reveals the critical differences between male and female microbiomes. You'll also learn his exact protocols for recovering from antibiotics, healing leaky gut and why fasting activates your gut's self-cleaning system.
