Insulin promotes synthesis of fatty acids in the liver. As discussed above, insulin is stimulatory to synthesis of glycogen in the liver. However, as glycogen accumulates to high levels (roughly 5% of liver mass), further synthesis is strongly suppressed.
You eat a high-fat meal or snack (this is the fun part). In a few hours, the fat begins to digest; this continues for several hours. The level of fat in the bloodstream (triglycerides) rises. High triglycerides in the bloodstream cause the liver to become resistant to insulin. When the liver is insulin resistant, it produces and secretes more glucose than usual. The blood glucose rises steadily as the livers glucose output goes up.
