Nobel Prize Scientist Was Asked “Is 18 Hours of Fasting Right?” His Answer Surprised Everyone...!!!

What does Yoshinori Ohsumi, the scientist who won the 2016 Nobel Prize for autophagy, actually say about fasting? Thousands of videos use his name to sell 16-hour and 18-hour fasting windows. But when people asked him if 18 hours is the correct interval, his answer was: "I can't answer it." In this video, we go through his own words from his Nobel press conference and his interviews. We also look at what a long-time colleague says about the 16-hour rule, and what human studies really show about fasting and cell recycling.
