Thanks for the welcome, guys!
chinadoll - I do indeed have the book, and have read and explained it to her, she just panics a lot! My Dad lost a lot of weight on Atkins a few years ago, with no real exercise owing to a disability, and has kept most of it off - he was very healthy throughout, and still is, but she was concerned that at 16 [as I was then], I was "too young to diet". The whole "it's a way of life, and healthy" thing didn't work. :P
But I do have my Dad's support, and my Mum is dubious but accepting it slowly as she has seen weight come off, and watch my skin improve, as well as me getting active and being a lot happier. She's getting there!
