Having less bread, disappeared to eat seconds (5,3)
I believe the answer is:
worse off
'having less bread' is the definition.
(with less money - bread can mean money)
'disappeared to eat seconds' is the wordplay.
'disappeared' becomes 'wore off' (wear off can mean to fade or disappear).
'to eat' is an insertion indicator.
'seconds' becomes 's'.
'woreoff' going around 's' is 'WORSE OFF'.
(Other definitions for worse off that I've seen before include "More out of pocket" , "Less prosperous" .)
