Does Sardine Fasting for Longevity Really Work?
Thu Feb 05 2026
Sardines are one of the most nutrient-dense, anti-inflammatory foods you can eat, but does eating only sardines actually count as fasting?
On today's show, I break down the growing trend of "sardine fasting," explain why it's gaining popularity, and clarify the key differences between true fasting, fasting-mimicking diets, and simply following a low-calorie, high-protein plan.
You'll learn why sardines, while incredibly healthy, do not lower IGF-1 or activate AMPK, why that matters for longevity and autophagy, and when a sardine-only day may—or may not—make sense depending on your goals.
Join me on today's Cabral Concept, Episode 3646, to find out whether the sardine fasting diet really works and what you can do instead to achieve better results.
Enjoy the show!
