Am I wrong to tell my friend to stop projecting because she's the one who's actually fat and not me?

My friend constantly comments on other people's looks, including mine. She almost always makes comments on my body, such as "heyy u got a tummy"(I have a TINY bit of a BELLY, not even noticeable. I'm 5'7 and my weight is in the 60 kgs+ range), or that I'm curvy from the front but not from behind because according to her, I have nice boobs but "straight" hips and legs, and I'm not a "proper" hourglass like her. She doubled down and said she's sure because she has seen me change in the locker room. She says that she herself is curvy both from the front and behind but it's not noticeable because she has a tummy. At this point I had enough and told her to stop projecting because she's the one who's actually fat and not me. She got pissed and isn't talking to me. Was I too harsh on her?
