Healthy? Congratulations! (4,3,3)

I believe the answer is:

good for you

I believe this is a double definition.

'healthy?' is the first definition.
('good for you' can be a synonym of 'healthy')

'congratulations' is the second definition.
(I've seen this before)

(Other definitions for good for you that I've seen before include "like a healthy steak?" , "Vegetables are meant to be" , "Well done! Health-giving" , "Very fatty steak may not be" , "Generally, fruit and veg is" .)

I've seen this clue in The Times.
