Not wanting to eat anything? Not quite - tripe etc will suffice (5)
I believe the answer is:
offal
'eat anything? not quite tripe etc will suffice' is the definition.
I can't judge whether this defines the answer.
'not wanting to' is the wordplay.
'not wanting' becomes 'off' (eg someone no longer eating something is 'off' it).
'to' becomes 'al' (I can't explain this - if you can you should give a lot more credence to this answer).
'off'+'al'='OFFAL'
Can you help me to learn more?
(Other definitions for offal that I've seen before include "Edible liver or heart of animal" , "Internal organs of an animal some find tasty" , "Entails and organs of animals, rubbish" , "Lights perhaps" , "Worthless parts of animal carcass" .)
