Parliament to mention rises based on consumption (8)
I believe the answer is:
dietetic
'based on consumption' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives can occasionally mean the same thing.
'parliament to mention rises' is the wordplay.
'parliament' becomes 'diet' (I've seen this before).
'to mention' becomes 'cite' (synonyms).
'rises' says the letters should be written in reverse.
'cite' backwards is 'etic'.
'diet'+'etic'='DIETETIC'
Can you help me to learn more?
(Other definitions for dietetic that I've seen before include "it's to do with what you eat" , "of nutrition" , "relating to food intake" .)
