She told talk show host Lorraine Kelly what she thinks women who hate their bodies should say to themselves every day.
"This is just a moment in your life," said Graham, "and if you want change, it's not a pill you take, a boyfriend that changes your mind, it's not a family member, it's you."
"Get down into your bra and panties, look yourself in the mirror and say, 'I love you, back fat, you are my best friend. Thighs, you're so sexy, you can't stop rubbing against each other.' Start talking to those things you don't really love, and all of a sudden your mind changes ... Confidence is in there, you just have to find the role model within you," she told Kelly.
Graham also took the opportunity to call out fashion's outdated labels and sometimes toxic selfie culture.
On why "plus-size" has to go: "The average size American woman is my size ... So to call us average and then place us in a category of plus-size, it's kind of awful," said the supermodel.
On selfie culture and seeking approval from others: "To find affirmation from [social media] likes is a whole other situation. I tell young girls, your likes is not your worth. Your worth has to come form within. And that's why I tell people [to try] affirmations: I always tell myself, 'I am bold, I am brilliant, I am beautiful, and I can have and do whatever I want."
