Coarse toast enjoyed by those who are fit (4,6)

I believe the answer is:

rude health

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

'enjoyed by those who are fit' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'coarse toast' is the wordplay.
'coarse' becomes 'rude' (I've seen this before).
'toast' becomes 'health' (I've seen this before).
'rude'+'health'='RUDE HEALTH'

Can you help me to learn more?

I've seen this clue in The Globe and Mail.
