A Japanese cell biologist Yoshinori Ohsumi won the Nobel Prize in Medicine in 2016 for his research on how cells recycle and renew their content, a process called autophagy. (two Greek words: “auto” or self and “phagy” to eat.) After about 17 hours of fasting, these cells start eating the cells that are the ‘debris’ of the body. They clean the house so to speak: dusting, sweeping, vacuuming, washing, waxing, deodorizing. Squeaky clean!!! They especially like ‘brown’ fat cells. The real bad boys, the visceral fat.
