"Body" by Julia Michaels is an apology song about the way she treats her partner. She is aware that her behavior causes insecurity and unhappiness in the relationship, but struggles to change her ways. Through the song, she expresses her desire to love herself and her body in the same way her partner loves her. She acknowledges her own flaws and struggles with self-acceptance. The chorus repeats the desire to love her own body like her partner does, to feel incredible and beautiful. She acknowledges that she doesn't see herself in the same way her partner does but wants to, expressing the desire for self-love and acceptance. The verses illustrate specific examples of her mistreating her partner, such as not allowing them to go out with friends and criticizing their appearance. However, the song is ultimately about self-acceptance and self-love, with Julia seeking to change the way she treats herself and her own body.
