Dr. Valter Longo recommends just 12 to 13 hours of daily fasting for most people — not the 16+ hour marathons many self-respecting biohackers swear by.

He says going longer every day could backfire, triggering nutrient deficiencies and long-term issues.

You may find this podcast surprising, and you may change your diet on the back of it.

Dr. Valter Longo is one of the world’s leading experts on longevity, fasting, and disease prevention.

He’s the creator of the Fasting-Mimicking Diet, author of The Longevity Diet, and a pioneer in nutrition-based healthspan research.
