to get myself motivated!

[FeedMyFaceWithJaffaCakes]

So I am FAT.
And I need to fix it.
I've been this way before (frightened to get on the scales this time!) and lost it all but over the course of six twelve months, it's all crept back on.
Not just that, but I am RIDICULOUSLY unfit.
My mum is forever going on about it too, she and my sis are very slim. It doesn't help. And I worry that soon my DP won't find me attractive anymore.
Can someone give me suggestions of good diets to give me a kickstart! (don't just say eat less, move more because obviously I know this already!)
Thank you delightful MNetters
