Wow! Welcome and congrats on your health. I assume you are a teenager - it must be hard to break with family over food, since it's so important to everyone.
My little sis flipped her lid when I first told her about this stuff - she said that Atkin's heart exploded, that meat isn't digested but just rots in the stomach, a lot of veggo nonsense. When I finally saw her this summer and she saw the "new me" she hasn't said a dang word since and she has finally stopped being a vegetarian though I suspect she still takes in too much soy junk and not enough protein.
