Meal turning bakers fat (9)
I believe the answer is:
breakfast
'meal' is the definition.
(breakfast is a kind of meal)
'turning bakers fat' is the wordplay.
'turning' indicates an anagram.
'bakers'+'fat'='bakersfat'
'bakersfat' is an anagram of 'BREAKFAST'.
(Other definitions for breakfast that I've seen before include "Eat in the morning" , "something to eat" , "Early meal" , "One could be first on the table" , "First meal at Tiffany's" .)
