Hello Kitty
Welcome to this wonderful site!
Good on you for making the decision to do something positive. Have a look at some of the recipes on here, there are a lot of really tasty healthy things to find!
I know exactly what you mean about exercise, I'm 36 and terribly lazy
I'm also not keen on the idea of going to a gym, so at the moment I'm making sure I get a walk at lunchtime at work, and occasionally shutting the curtains, making sure my husband won't disturb me, and dancing to bad pop music - at least it's a start!
I read this site every day since I've started again, it's incredibly motivating. Read some of the success stories in the goals section, it really makes you realise that it's actually possible to do it.
Good luck!
