Went without food (6)
I believe the answer is:
fasted
'went without food' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for fasted that I've seen before include "dieted?" , "Abstained from food as in penance" , "Ate no food" , "Went without food for a period" , "Went voluntarily without food" .)
