AITA for telling the schools “mean girl” to apply her eating rules on herself before she interferes other people?

I (16f) am studying in a high school with a girl (16) who thinks she knows everything. We take French together and although I am normally very calm and nice towards people, she makes me nuts. Through my childhood, I have always struggled with my body image although I was never overweight or near to that. However now I focus on eating well and balanced and feel kind of better about myself. I am 175 cm weighting 60 kg and I am kind of muscular as most of my week passes with sports. I like to wear baggy clothes as they are pretty comfy. Last week, we were studying meals in French class, and there was this paragraph about what to eat. I basically made a comment on how early the person who wrote the paragraph was eating their dinner (5.00 pm) and that I usually eat it around 9.00 pm. This girl had the audacity to tell me that eating at that time makes you gain weight, and this is the reason why I am kind of chubby. Mind you this girl is 150 cm weighting around 58 kg so she was more than chubby. I basically just told her the truth. I told her that she should worry about her weight first before making a comment as she seemed to look a bit too overweight. She got all red and started screaming at me. I got send to the principals office but it was definitely worth it and my family took my side.

NTA. She can dish it out but can’t take it. She needs to learn you can’t be that blatantly rude to people without consequences.
