Watching your edacious uncle at an all-you-can-eat buffet would be an alarming experience, since edacious means eating huge amounts of food ravenously.

If you go all day without eating, you're bound to be edacious by dinner time. Although sometimes the adjective edacious is used to simply mean "related to eating," it more usually implies a gluttonous devouring of food. The root word is the Latin edax, "voracious or gluttonous," which comes from edere, "to eat."
