Hi Lou
I was sure i had replied to you as I remember reading your post..sorry, that it does look as though I have posted it.
Sorry to hear about the gain, but it definitely cant be fat, it has to be your body getting used to eating again. I know you will have followed the refeed to the letter.
Dont worry too much, but like you say, you have always seen the figures coming down, so it is hard....rest assured it isnt fat and you havent done anything wrong.
I am sure it will right itself....keep positive sweetie.
Take care and you have done so well, amazing really!!!
