Just going out of my way to mention something:

Monster Girl Encyclopedia World Guide I: Fallen Maidens

"Spirit energy is the greatest treat for monsters, but there are many of them that mainly eat food other than mana, and even monsters that mainly eat energy can also replenish nutrients by eating normal food."

And

"Even among monsters that primarily feed on mana, there are many that also taste and enjoy food purely for amusement."

So yeah, no monster without spirit energy will ever starve as long as they have access to regular food.
