O.k. We had our meal. Our digestive tract is extracting or producing all available glucose from the foodstuffs und places it into our blood.

A regulatory circuit always wants to get back to equilibrium.

If somewhere in the system a component is changed and the equilibrium of the system is out of balance, the regulatory circuit changes another component to reachieve balance.

The first change in the system is a change of the amount of glucose in the care system nourishing our cells: in our blood.

The second change is a rebalancing attempt. The glucose is supposed to vanish from our blood. Our hypophysis receives a message blood sugar level is rising to – let´s say – 200 ml /dl .

The hypophysis sends an order to the pancreas gland to produce a fleet of transport ships to bring glucose away from blood, into the storage rooms, our cells: The fleet of transport ships is called Insulin.

The fleet of insulin ships however is not just Robin and a few merry men, it´s a royal fleet of many many ships to do the job. Too many, to tell the truth. All these insulin-ships take glucose on board and store it away into the cells.

What now? No more glucose at all in our blood.

The message to our hypophysis is: very very low level of glucose in our blood. Code orange not enough energy fuel available for ongoing energy production in our muscle cells!!

Low level of glucose? The answer of the hypophysis is: low level of glucose!! Code red!! Low level of glucose!! All hands on deck!! Code: HUNGER!! HUNGER!! HUNGER!! Make our owner get up, run to the next food source and make him eat.

And thus…

…not the legend begins,

but: if our food supplied a high amount of stuff making it possible to release a lot of glucose into our blood, the insulin – reaction is far over the top.

The hypophysis orders to overflow our blood with a giant fleet of insulin ships.

So even after food intake we might be sitting here and become hungry again a very short time after our meal..

Tomorrow: energy needs and body weight.
