I have spoke to my parents about going vegan and they don't agree with it! They say it's unhealthy and no matter what I say won't change there view on vegan ism?! My mum tried to be vegan when she was a teenager and ended up over exercising and I'm assuming she didn't eat enough as this worsened her binging, purging and anorexia! What should I do to become vegan? Is there a way to convince them after this experience? How can I convince them to allow me to live this lifestyle?
