My DD2 (15) has always been a picky eater and now has decided to go vegan "to be more healthy" I told her that it was very easy to achieve a healthy diet with going vegan but she was having none of it. I have noticed however she has been eating nowhere near enough and is still going to the gym, I'm worried that she's starving herself and using being vegan as an excuse not to eat things. DD1 (18) keeps an eye on her and often tells me she's lied about eating things or just not eaten anything. I'm worried and I know if I approach her about it she will not talk to me as we do not have the best relationship.
