'following a limited diet' is the definition.
The definition suggests an adjective which matches the answer.

'terribly unfair it primarily alters recipes' is the wordplay.
'terribly' indicates an anagram.
'primarily' suggests taking the first letters.
The first letters of 'alters recipes' is 'ar'.
'unfair'+'it'+'ar'='unfairitar'
'unfairitar' anagrammed gives 'FRUITARIAN'.

'is' is the link.
