Diet losing weight from round here (5)
I believe the answer is:
local
'diet' is the definition.
(lo-cal is short for 'low calories')
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for local that I've seen before include "Nieghbourhood pub or its customer" , "In nearby area" , "Confined to a place" , "nearest boozer!" , "Pub - not far away" .)
