WW Winter Challenge

I joined the Winter Challenge on the WW forum a month back. It's been a slightly rocky month with my little blow out but I still think my goal is achievable with a little hard work and good quality choices.

My goal is to be 90kg by the 31st of May. Meaning I need to lose 8.9kg in 8 and half weeks. Optimistic? Maybe, but i'm going to give it my best shot!
