I mentioned this site in a thread about fasting.
This is what I pulled from the site about hunger after not eating.
Hunger:
Most are surprised by the disappearance of hunger once the border is crossed into fasting’s land of silence. After a day or two, hunger’s voice will be rare indeed. Craving can continue on for some days longer, and then at last stillness, leaving the deep groans of the soul. Once the body quiets, the richer connection with our spiritual hunger can be felt. There is nothing like it!
The odd time hunger can flare up, more often in a juice fast than water. This could be due to excessive pulp in the juice, reawakening digestion. If hunger persists, try straining your juice or adding some prune juice to clean out the digestive tract.

Basically your digestion is not active. There are no juices being produced. Its similar to taste buds. When your mouth gets a taste of food it starts to salivate (natural digetive juice) and this is the beginning of your digestion. The same thing occurs when food hits the stomach.
Another misconception about hunger pangs is that it automatically means hunger.
A lot of the time it is the body trying to regulate insulin levels. It may also mean dehydration.
I would say the best way to test it out is breaking the cycle by having just 1 mouthful of food and wait for a reaction. I bet your body will ask for more
