The Autophagy Maester - Yoshinori Ohsumi: The Science of Self-Renewal

Send us Fan MailHave you ever wondered what happens inside your body when you don’t eat for a while — when you give yourself space between meals? In this week’s episode of Project Weight Loss, we explore that quiet magic with the story of Nobel Laureate Maester Yoshinori Ohsumi, whose discovery of autophagy — the body’s natural process of self-cleaning and renewal — changed how we understand health, vitality, and longevity. From his humble lab in Japan to the moment he glimpsed a new world under the microscope, Ohsumi’s curiosity reveals how our bodies are wired to restore themselves, especially in moments of pause.We’ll talk about how autophagy connects to fasting, weight management, brain health, and aging — and why giving your body a little space to “dine in” can make such a difference. You’ll hear about Ohsumi’s groundbreaking experiments, his partnership with his wife and collaborator Mariko Ohsumi, and how their discoveries invite us to see self-renewal as a natural rhythm of life. I’ll also link this episode to my earlier one on the Blue Zones — where long-living communities show us what it means to live in harmony with our biology. Listen in, reflect, and maybe even give your body that gentle reset it’s been asking for.Quote of the Week:“We are wired for feast and famine, not feast, feast, feast.” — Dr. Jason FungListen to my related episode: The Blue Zones: The Secrets to Living Citations1.    Ohsumi, Y.
