If the body sees that your glycogen stores are full, it will take the energy and store it as fat. If we start to use energy over an extended amount of time, the body will conserve its glycogen stores and start pulling from fat.
The body does this every second of every day, so we are in a constant flux of being over or under fed, but it all balances out over a period of time.
I will not be offended if someone corrects me. I am trying to explain as best I understand it, but there are others with a much better understanding. Gbrice did some 'splaining above.
