A word that implies hungry but all food tastes bad and unappealing
Solution 1:
Avoidant/restrictive food intake disorder (ARFID). If you have ARFID you will feel a very strong need to avoid food in general or certain foods because of their smell, taste or texture. The idea of eating can fill you with anxiety. ARFID does not tend to be connected to issues with body image – it is an anxiety about the process of eating itself.
