Writer's point regularly belies little for the consumer (6)
I believe the answer is:
nibble
'little for the consumer' is the definition.
(a little bit of food to be consumed)
'writer's point regularly belies' is the wordplay.
'writer's point' becomes 'nib' (nib of a pen, something which writes).
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternating letters of 'belies' are 'ble'.
'nib'+'ble'='NIBBLE'
(Other definitions for nibble that I've seen before include "Take small bites of" , "Bite gently and eat a little at a time" , "Take tiny bites" , "Eat with small dainty bites, like mouse" , "express tentative interest" .)
