I am currently 10st 7 and would like to be 8st 7 by xmas. I am 5ft 3 so that would be a good weight for me. I actually went from 13st 11 to 9 st 9 last year then put nearly a stone on after my wedding. I am going to Australia for a holiday on 2nd Jan so would love to be trim and slim by then. Can I do this? And would anyone like to join me?
