Thank you everyone.
Today I have had the 3 meals recommended in the book but have only had 604 calories. I don't feel starving but I do know that that isn't enough. Since reading the books it has been like a switch being flicked and I know I can do this and have stopped treating food like something other than fuel. If I tried to explain my issues you would think I belong on Mars but suffice to say I have changed my whole mindset about eating.
