Look for healthy sounding outcome (6)

I believe the answer is:

sequel

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

'outcome' is the definition.
(I know that sequel is a type of outcome)

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for sequel that I've seen before include "Big film follow-up" , "Follow-up work" , "Something following an earlier event" , "Upshot - what follows" , "Continuation of an earlier story" .)

I've seen this clue in The Guardian.
