Desire subtle changes be removed? (4)

I believe the answer is:

lust

'desire' is the definition.
(lust is a kind of desire)

I don't understand the remainder of the clue.

(Other definitions for lust that I've seen before include "Depraved desire" , "Passionate desire" , "Libido" , "Lecherousness" , "Deadly sin of extreme passion" .)

I've seen this clue in The Guardian.
