For example, spots upcoming heavy meal (6)
I believe the answer is:
stodge
'heavy meal' is the definition.
(stodge is heavy or filling food)
'for example spots upcoming' is the wordplay.
'for example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'spots' becomes 'dots' (I have seen 'Tiny spots ' mean 'dots' so perhaps 'spots' could also mean 'dots').
'upcoming' is a reversal indicator.
'eg'+'dots'='egdots'
'egdots' back-to-front is 'STODGE'.
(Other definitions for stodge that I've seen before include "Heavy food (colloq.)" , "Sticky stuff" , "Steamed pudding" , "Food that's hard to digest" , "heavy fare" .)
