Suffering from lack of food (8)
I believe the answer is:
starving
'suffering from lack of food' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for starving that I've seen before include "certainly not scoffing" , "feeling famished" , "Ravenous, really hungry" , "Dying of hunger" , "Suffering from lack of food" .)
