The science-backed protocol to double autophagy and lose weight using sardine fasting, with Dr. Dom D’Agostino. Try ARMRA Colostrum for yourself, go to https://armra.com/theprimalpodcast or enter code THEPRIMALPODCAST to get 15% off your first order.
Is there a single metabolic switch that can accelerate weight loss while repairing your cells? In this episode, world-renowned metabolic researcher Dr. Dom D’Agostino (PhD) joins us to explain the science of autophagy, ketosis, and the gut microbiome. Referencing decades of laboratory research and clinical observation, Dr. D’Agostino explains why the traditional calories in, calories out model fails to account for cellular signaling and nutrient density. From the specific biochemical benefits of sardine fasting to the role of ketones in preserving gut barrier integrity, this conversation provides the medical clarity needed to optimize your biology. Whether you are looking to reverse metabolic dysfunction or seeking the latest data on nutritional ketosis, this episode bridges the gap between science and practical human experience.
In This Episode, We Reveal:
* The Autophagy Switch: A scientific breakdown of how to double cellular cleanup and the specific dietary triggers that initiate protein recycling.
* The Sardine Fasting Protocol: Why this specific high-protein, high-omega-3 approach is a clinical powerhouse for metabolic health and rapid ketosis.
* Ketosis & Disease Prevention: Moving beyond the scale to understand how ketones function as signaling molecules for longevity and neuroprotection.
* Gut Barrier Integrity: The relationship between the microbiome and metabolic health, and why maintaining the gut lining is the first line of defense against systemic inflammation.
* Translating Research to Reality: How to apply cutting-edge metabolic data to daily life for sustainable weight loss and disease prevention.
