Food symbolism
The extended metaphor of food indicates love and connection on this show. Both Lorelai and Rory only eat with people they feel connected to, and whenever they declare they're not hungry it means it's the person/situation they're uncomfortable with, as indicated by them becoming hungry again when they leave the situation.
Additionally, the junk food seems connected to silly or playful states of mind, while whenever they eat healthy food it's connected to something more serious, like when Luke insists they eat healthier, Friday night dinners, and when struggling economically.
Recurring foods, apart from the pancakes and eggs and often doughnuts they have at Luke's, are paella and devilled eggs (though not together).
