After 4 days without food, glycogen stores would be depleted, and gluconeogenesis becomes the primary source for maintaining blood glucose levels.  During periods of starvation and fasting the body will begin to divert stored fats into the metabolic pool in order to allow for adequate energy production. When adipose tissue is stimulated to release fatty acids stored in triglycerides, the glycerol backbone diffuses into the blood and is delivered to the liver. Within the liver glycerol is phosphorylated and converted to DHAP and then diverted into the glucose production via gluconeogenesis
