Food lover's gut more wobbly (7)
I believe the answer is:
gourmet
'food lover's' is the definition.
(lover of fine food)
'gut more wobbly' is the wordplay.
'wobbly' is an anagram indicator.
'gut'+'more'='gutmore'
'gutmore' with letters rearranged gives 'GOURMET'.
(Other definitions for gourmet that I've seen before include "Gastronome" , "Epicure" , "bon viveur" , "One has expert knowledge of food and wine" , "One has a passion for fine food and wine" .)
