Intermittent fasting

What happens during fasting?

After fasting for few hours blood glucose levels drop, as it is absorbed by cells, dropped glucose levels trigger the pancreas to release glucagon to turn off glycogen synthesis in the liver and stimulate its breakdown into glucose. The glucose is released into the bloodstream to serve as a fuel source for cells throughout the body. If glycogen stores are depleted during fasting, alternative sources, including fatty acids and proteins, can be metabolized and used as fuel. These changes are also accompanied by other changes at the cellular levels called autophagy where cells digest and remove old and dysfunctional proteins that build up inside cells.


There are also some studies that suggested changes in gene expression related to protection against diseases.
