After a couple hours I figured out how to hide the HUD for cutscenes.
1. Copy of the common event 125 ( Hunger/Thirst Bars ) and create a new one as 128 (Hide HUD)
2. In the new common event 128 under the comment that says "SET THE COORDINATES FOR THE BARS." set the coordinates for X and Y to "1000" for both
3. Set the common event to start as parallel from switch 226.
4. rename switch 226 to "Hide Hunger/Thirst HUD"
5. Every time you want to hide the hunger system you turn off switch 225 and turn on switch 226. Then to return the HUD turn off 226 and turn on 225.
