Piteous asides about being fat (7,6)

I believe the answer is:

adipose tissue

'being fat' is the definition.
(I've seen this before)

'piteous asides about' is the wordplay.
'about' indicates an anagram.
'piteous'+'asides'='piteousasides'
'piteousasides' is an anagram of 'ADIPOSE TISSUE'.

(Another definition for adipose tissue that I've seen is " Cells that store fat".)

I've seen this clue in The Guardian.
