Potential jealous family members

So I started losing weight in February I’m currently 13 pounds down. And everybody in my household knows that i am on a diet & they respect that, but yesterday my mom brought juice home and asked me why didn’t I drink it & I said because I don’t drink juice anymore .. I had completely cut out sugar never the less, she says after that “well your naturally big boned so your always gonna be a little big” I felt like she was trying to say even though I lose weight I’m still gonna be big .. which was uncalled for because it wasn’t like we were talking about my weight or anything I could see if I was asking but I didn’t. Than today she says “your butt is getting flat” and than she told me I was getting “crazy” with my diet ... I just kinda laughed it off but it’s just annoying, I feel like you don’t say things to people like that who are losing weight it’s rude.
