Explanation:
Skipping lunch leads to starvation leads to a decrease in blood glucose level and low energy levels.  
This lack of glucose increases metabolism of reserved fat for energy production. There is an increased oxidation of fatty acids stored in the liver which leads to increased production of ketone bodies from acetyl CoA. Brain metabolism also follows the same path where fatty acids are converted to ketone bodies.  
Further, impaired insulin secretion from beta cells and elevation of epinephrine during starvation activates hormone-sensitive lipase
The activity of glycogen synthase is also increased during starvation due to increased glycogen metabolism.
However, insulin secretion is affected due to starvation.

Well with blocked vessels, lets use plaque buildup as the reason for blocked vessels. It's Like trying to match together two puzzle pieces that don't fit. The piece if forced together, will be a tight fit much like how blood cells/platelets trying to fit through a small area. The pressure will be increase because the more pressure that is being put on will help to push blood through a clotted area.
