Kara’s obsession w food also makes a lot if sense when u remember that for kara, until she became supergirl there really wasn’t much physical activity she could do that gave her endorphins bc she wasn’t using her powers and just normal everyday activity does nothing for her like is there anything other than sex and food that would do much? I am not an expert on the subject so idk but when you have Massive PTSD and need stress relief and physical activity doesn’t work and all your other senses are constantly dialed up to a bajillion it makes sense Kara loves food
