I know some of those naturally skinny girls, and actually they do something different to me (and maybe you), they don't over eat! They might have a packet of sweets but then they would miss a meal, they have a takeaway but know when they are full.  I don't do either of those things.  That's how they are naturally skinny, they listen to their body.  I listen to something else and if I knew hoe to re programme then I probably wouldn't need to be on this diet! Xx
