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

'pub?' is the definition.
(one's local pub)

'short for low calorie' is the wordplay.
'short for low' becomes 'lo' (I can't justify this - if you can you should believe this answer much more).
'calorie' becomes 'cal'.
'lo'+'cal'='LOCAL'

Can you help me to learn more?

(Other definitions for local that I've seen before include "Regional, parochial" , "Regional; a pub" , "Close to home - public house" , "Of the particular neighbourhood" , "stopping train" .)

I've seen this clue in the Sydney Morning Herald.
