It depends. Some children just say no to certain junk food at parties, and no one notices. Some children don't want to feel different so they take time off the keto diet for a few hours (if health conditions permit this). Whilst other children feel so incredible and finally lose weight (which in itself is isolating for many children) or are seizure-free (which also cuts off many children from participating in parties), they don't want to go back to sugar and junk food.
