'snacks' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'famed artist is full of energy' is the wordplay.
'famed artist' becomes 'munch' (painter Edvard Munch. I am not sure about the 'famed' bit.).
'full of' means one lot of letters goes inside another.
'energy' becomes 'e' (physics symbol as in E=mcu).
'is' placed around 'e' is 'ies'.
'munch'+'ies'='MUNCHIES'

'from' is the link.
