Instigated dieting revolution (7)

I believe the answer is:

ignited

I'm a little stuck... Click here to teach me more about this clue!

'instigated' is the definition.
Although both the answer and definition are past participle verbs, I don't see how they can define each other.

'dieting revolution' is the wordplay.
'revolution' indicates an anagram.
'dieting' with letters rearranged gives 'IGNITED'.

Can you help me to learn more?

(Other definitions for ignited that I've seen before include "Lit" , "Gin diet (anag.)" , "Set alight" , "fired" , "Caught fire" .)

I've seen this clue in The Daily Express.
