Don't suppress her at this time, because she will bounce back immediately, just like when she says she is too fat and you say she is fat, she will bounce back immediately and say my mother is fat, deceiving you. I'd think so if I didn't tell you. In this case, you can simply comfort her and compare her with a third party. For example, tell her that your figure is quite good. Although it is a little worse than those models, it is still quite standard. When she says she is short, you can say: Your height is actually ok, but it is still a little higher than the average girl. Change the subject again
