Hi. I'm looking for an idiom in English, which could be as close as possible to Estonian "(eating something) with a long tooth".... or to German "Ohne Appetit Essen". Thank you, Kadri
"Long in the tooth" in the U.S. means "old."
"Ohne appetit essen" is no appetite.
Reluctantly can be expressed as "dragging your feet" or "dawdling."
If one has no appetite, we simply say, "I'm not hungry."
If one is reluctantly eating and it is a child, we tell him to "quit playing with your food and eat."
